The importance of this phrase is well appreciated by mem- bers of the food industry. The ever increasing need for greater efficiency in the food business, with particular reference to Overton's Markets, Incorporated, has led the author to a study of food distribution centers. This study was conducted on a limited scale and the procedure followed will be explained in a following section under background of study. Statement of the Problem The basic problems of concern in this study involve the methods employed in the operation of the food distri— bution center of Overton's Markets, Incorporated. The need for the improvement of these methods in terms of efficiency and profitability has led the author to a study of food operations of similar size and volume.

The interviews were held with the following members of each organization. Mr. Wood, Warehouse Manager, Meijer‘s Super Market, Grand Rapids, Michigan; and Mr. Dewey, Warehouse Manager, Eberhard's Super Market, Grand Rapids, Michigan. i To bring this information up to date, the author mailed 1 letters to each company. Mr. Holton provided the information on Meijer's operation and Mr. Corbett up dated the information to coincide with Eberhard's present Operations. The material will be divided into two sections. Meijer's Super Markets This organization consists of seventeen super markets. Grocery merchandise is supplied to these retail outlets by a centrally located food distribution center. The most distant supermarket is sixty miles from the distribution center. The delivery time to this store is approximately one hour and thirty minutes. The grocery section of the Win-ox. J taming f: (A) I: (I) warehouse contains 90,000 square feet. Thirty full-time employees comprise the warehouse crew with each employee working forty hours per week. The following information involves the procedures used by this company in conducting the operation of the food distribution center. Procurement of merchandise. In the procurement of merchandise the following four basic categories will be considered: 1. The procurement of merchandise already stored in the distribution center. The IBM Inventory Control System is used by this company as a guide to reordering merchandise. The second category involves the procurement of new items. Under the organizational structure of this Operation two men perform this function. The two men are the grocery buyer and the grocery .department sales manager. New items are presented to these two men and after such factors as, the reputation of the manufacturer, the success of this product in other markets, and the movement of similar items already stocked, are considered a decision is reached as to whether the item is accepted or rejected. The third category is special promotion merchan- dise. The procedure followed by this company is to handle large quantities of special promotion 49 merchandise in the distribution center and make shipments to the stores as orders are placed by each store manager. If the special promotion involves only a few cases, shipments are made directly from the manufacturer to the retail outlet. 4. The fourth category involves drOp shipment mer- chandise. The greater portion of the grocery merchandise carried by each store is handled through the distribution center. Only those items requiring daily delivery and service are purchased on a drop shipment basis. Receiving_merchandise in the distribution center. The equipment used to receive merchandise in the warehouse consists of pallets and fork lift trucks. As merchandise is received it is placed on pallets which in turn are picked up by the fork lift trucks and transported to the section of the warehouse where the item is stored. To prevent confusion and congestion in the warehouse, separate docks are used to receive and ship merchandise. Eight docks are provided in the distribution center. Three of the docks are used to receive. These docks are Opened from 7:00 A.M. to 2:30 P. M., Monday through Friday. The only merchandise accepted at any other time is perishable items. The remaining five docks are used to ship merchandise to the stores. Ordering merchandise by stores. Each store in this organization submits an order form to the warehouse each week. The form is printed by IBM. The following discussion will provide the reader with a better understanding of the procedure followed. Each item appearing in the order form is assigned a code number. In addition to providing information on the size, description and retail price, the order form has four tear strips. Each tear strip has a code number for each item and a column for quantity ordered. These tear strips are filled in by the store manager and submitted to the warehouse. The order form can be used over a four week period, one strip for each week. Orders placed by the seventeen stores located in the city may be submitted on the same day they are filled. This is usually Tuesday of every week. The stores which are located outside the city must submit its orders one day in advance due to the delivery time required to reach these i stores. These orders are usually received on Tuesday or Wednesday of each week, and shipped on Thursday. After orders are processed priced and extended at cost and retail, they are forwarded to the distribution center to be filled. Order selection. Orders for the individual stores are assembled by the use of Rad—ox trucks. The Rad-ox is automatically moved to the various areas of the warehouse by a radio attached to the belt of one of the men comprising the selection and assembling team. In the Meijer's system Y; C” o u w i Y I 2 3 a: fli. O» an O .1 to n; hula a 60.3 «.fv n.»\ flu i—1—7t~ 'PES CC; .1“! . 5 t *3. .F J 2"“ of order selection and assembling the number of men used varies in accordance to the size of the order. The function of the men are as follows: I. The number one man Operates the Rad—ox truck. 2. The number of men who select the merchandise varies in accordance to the size of the orders. 3. After the merchandise has been selected and assembled at the loading docks, two-man crews are used to load the delivery equipment. The orders are loaded according to the location of the stores. Equipment used in the distribution center_procedure. According to Mr. Holton, operations director, the equipment used by Meijer's Super Markets in the distribution center consists of (l) 2 Rad—ox trucks and (2) 8 fork lifts. The equipment used in delivering merchandise to the individual stores consists of four tractors and sixteen trailer units. The extra trailer units are used when an entire trailer unit is filled with a single store order. The trailer is dropped at the store and then picked up after being unloaded. Location of merchandise in the distribution center. This company uses two systems to locate merchandise in the distribution center. The two systems are: 1. By movement--Fast selling merchandise is placed in areas near the shipping docks to expedite the 51 52 assembling and selection of merchandise for store orders. 2. By specific spot or slot--75% Of the items received in the center are placed in a specific spot. This procedure is also followed to expedite the assembling and selecting functions. Under this system a number is assigned each item received in the distribution center. The number is placed on the delivery manifest which is forwarded to the IBM room. This number is punched into master card for each item. This card is used to print additional cards used when orders are prepared in the IBM department. When the order is billed on the IBM Accounting Machine the slot number is printed on the invoice. This facilitates order selection as well as the receiving function (At store level) Distribution center inventory. The International Business Machines method of Inventory Control provides the company with a record Of the inventory on hand and sales by item. In connection with this system a physical inventory is taken quarterly. Checking merchandise. The procedure followed in checking merchandise for correct quantity and quality is very important. The procedures followed in performing the checking function are: 53 l. A complete check of all merchandise received by the center is made by using the duplicate COpy of the purchase order placed by the company. The purchase order contains information on the quantity, the size, and how the item is packed. When the merchandise is received the purchase order becomes the receiving report. The receiving report is used by the receiving supervisor to check the items as they are unloaded from the supplier's truck or railroad car. 2. A piece count against the order form is made of the merchandise received in the warehouse; under this method the total number of cases received at the retail outlet is compared with the total number of cases for which the store is billed. If the check turns up a discrepancy of ten cases or less then nothing is done, however, if the discrepancy involves ten or more cases measures are taken to correct the error. Distribution center security, The protective measures taken by this company and the employees responsible for performing each are as follows: 1. The warehouse foreman is responsible for opening the warehouse each day and for turning on the lights. i 4,. \J its; ‘3 s dist +J~ use 0, ;~. ".- the... C \ h q a .

This employee is also responsible for turning off the lights. The shipping supervisor is responsible for securing the trucks each day. The trucks are secured with a seal each night and the seal is recorded in the distribution center records. The ‘ shipping supervisor is the only individual allowed to break the seal and Open the delivery trucks each day. Eberhard's Super Markets This organization consists of twenty-four super markets and three food distribution centers. The three distribution centers are located within two hours driving time of each store. There are nine full time employees used in the operation of the company's warehouses. These employees work forty hours per week. The distribution centers are used to supply grocery merchandise to the twenty- four stores of the organization. In addition to these facilities, the company is also a member of Grand Rapids Wholesale Company. The following information involves the procedures followed by Eberhard‘s Super Markets, Incorpor— ated, in performing the functions of a food distribution center. 55 Procurement of merchandise. Consideration will be given to the following four basic methods used in the pro- curement of merchandise. 1. Merchandise which is already stored in the food distribution center. The process involved here entails the reordering of items to replenish the existing stock. This company has installed the IBM method of Inventory Control. This system provided management with information which serves as a guide to reordering merchandise. The second category is the procurement of new merchandise for the company. The responsibility for performing this function rests upon one grocery buyer and a buying committee. The buyer screens all new merchandise and accepts only those items which warrant further consideration, by the buying committee. After the items have been screened by the grocery buyer they are considered by the committee. The buyer makes the presentation to these members from the in- formation provided by the brokers' or manufacturers' representative. After the committee has considered such factors as the size of the potential market for the product in.their area, the sades of similar products already carried, and the amount of promotional activity to be conducted by the 56 supplier, decisions are made as to whether the product will be accepted or rejected. 3. The third category involves the procurement of special promotion merchandise. In this company the procurement of this type of merchandise is handled in the following manner. The initial orders placed by the individual stores are shipped directly from the manufacturer to the retail outlets. However, if special promotion merchan— dise is reordered by the company, the deliveries are made to the company's food distribution centers. The merchandise is distributed from this point to the stores in accordance with orders placed by the store managers. 4. The fourth category is drOp shipment merchandise. The only merchandise which is not handled through the warehouse involves items which are delivered and serviced daily at the individual stores. Receiving merchandise in the distribution center. This company operaties three distribution centers. Conveyors are used to receive merchandise in two of the distribution centers. The receiving procedure in the third warehouse involves the use of skids transported by power trucks. The skids are stored near the docks of the warehouse. As merchandise is unloaded at the dock it is placed on the skids. As each skid is loaded it is lifted by the use 57 of power Jacks and transferred to the area in which the items are stored. Separate docks are not provided for incoming and outgoing merchandise, nor are these functions allocated to certain areas. However, shipping and receiving are allocated to certain times. Merchandise is shipped from the warehouse to the stores on Thursday and Friday of each week. Merchandise is received on Monday, Tuesday, and Wednesday of each week. The only exceptions made by this compnay in receiving merchandise is when a refusal to unload a carrier would result in holding the driver in town over the week end. Ordering merchandise by stores. A preprinted order form is used. The date for the weekly order to be submitted to the food distribution centers varies according to the size of the grocery orders and the location of the stores. The time interval varies from one day and three days. All orders received from the stores are priced by the use of IBM equipment. Order selection. The selection and assembling functions of reading the order form, selecting the merchan- dise, placing the merchandise on the conveyor or skids, and loading trucks are performed by warehouse personnel. Merchandise is placed on trucks according to the location of the stores. The first order to be delivered on the truck 58 route is the last order to be placed on the truck. Each order is separated in the delivery truck through the use of fish nets. Equipment used in the distribution center procedure. According to Mr. Dewey, warehouse manager, of Eberhard's Super Markets, the equipment used in the Operation of the distribution centers consist of skids, power trucks, and a conveyor system. The equipment used in delivering merchandise to the individual stores consist of seven tractors, nine trailers and two straight trucks. Location of merchandise within the distribution center. Merchandise is stored in the company's distribution centers by specific spot or slot. Distribution center inventory, The IBM Inventory Control method provides the company with a perpetual inventory. Reorder stock conditions are called to the buyer‘s attention daily in the form of signal cards. These signal cards are a by-product Of prebilling, and reach the buyer before the corresponding physical stock position is reached.1 A physical inventory of all merchandise in the warehouses is taken quarterly. Checking merchandise. 1. Checking merchandise into the center. A complete check is made of all merchandise received.

The following recommendations for the improvement of Overton's Warehouse Operations are made. Reordering Merchandise The procedure used by Overton's of complete dependence of manufacturer's representatives and brokers for ordering l merchandise should be discontinued. The International Business Machines Unit Tub File Method of Inventory Control should be installed and all merchandise ordering should be done by designated employees.1 This system Of Inventory Control will provide the following records and other information needed by Overton employees to order merchandise more efficiently: 1Under the Tub file System, the IBM card punch, accounting machine, reproducer, and sorting machine are used. This system also involves the use of master cards and detail cards. For each product in the warehouse there is one master card; from this card the reproducing machine punches the same information in detail cards for each product unit. The number of detail cards depends on the number of cases of each item in the ware- house. The detail cards are placed in files in predetermined sequence. The detail cards are pulled from the files to fill orders and placed in the accounting machine to prepare invoices. 80 1. Information regarding item movement. Buyers will be able to buy to a specific rate of stock turn. 2. Reorder points are flagged for the buyers attention. To arrive at a reorder point, the average movement for a given period and the approximate time between the placement of the order and the arrival of the merchandise must be determined. The reorder point assures adequate stocks until the merchandise arrives 3. The tub file duplicates the warehouse inventory in card form. Any difference in the tub file and ware- house inventory is due to errors or shortages. A. Item turn can be determined and slow movers detected. Product movement reports can be provided for any desirable pcricd. U"! Increased labor efficiency is achieved through better scheduling and more efficient layout. In addition to the use of IBM for inventory control the equipment can be used to achieve greater efficiency in the handling of: 1. Accounts Payable. 2. Payroll. General Ledger. 3. 4. Accounts Receivable. Procurement of New Merchandise The position of a grocery buyer should be created. His function will be to make all buying decisions. The present 81 buying committee should be abolished. The buyer should be provided a Weekly Movement Analysis report. Special Promotional Merchandise In Overton’s Operation, two factors should be considered to determine whether or not special promotional merchandise will be handled through the Distribution Center. 1. Is the minimum order size compatable with stock turn requirements? 2. Is the cash discount adequate to cover warehouse handling cost? Ordering Merchandise by Stores The use of an order form compiled by using IBM cards and equipment is recommended.2 The order form provides descriptive information as well as code numbers for all items listed. The order form contains four tab strips, each one containing item code numbers. The order form is filled in by placing the quantity ordered next to the code number. The strip is then removed and forwarded to the IBM department for processing. (See Appendix B, page 113.) The advantages derived from this type of order form are: 2IBM Order Form. The master cards print information regarding pack, size, description, cost and code number on the order form. 82 3 1. New order forms are printed every four weeks. (Under the system employed by Overton‘s, large quantities of printed order forms were purchased to achieve a more favorable price structure.LL In a few weeks this resulted in an Obsolete listing of merchandise handled in the distribution center.) 2. A record of weekly store orders for each item is provided. This information serves as a guide in preparing the store order. 3. Printing costs are reduced since the item des— cription and code numbers are printed by the IBM Accounting Machine from master cards. 4. Mailing costs are reduced since only the order strips are sent to the distribution center. Order Scheduling Store orders should be received by the warehouse on schedule usually one day in advance of delivery. Store deliveries will be by schedule and additional deliveries by Special arrangement only. 3May vary in weeks, however, four weeks appear to be the most acceptable period. 11LOverton's order form contained information regarding the description of each item including the pack, size, cost in the warehouse at the time the order form was printed. 83 Pricing_Goods Orders The IBM equipment will be used to price orders. (See Appendix C, page 115.) Detail cards are pulled from the tub files in accordance with the orders placed by retail outlets. The detail cards are then run through the accounting machine which automatically prints the information contained in the card on the invoice. The invoice would then be forwarded to the warehouse to be filled and shipped to the retail stores. The advantages of this system are:5 I. Order picking will be more efficient. Items can be listed on the invoice in the same sequence as the merchandise is arranged in the warehouse. 2. Items can be located to achieve the most efficient use of warehouse space. This is possible since the arrangement can be entirely independent of the order form sequence. 3. Items which are out of stock will not be printed on the invoice. A. The total number of pieces can be automatically printed on the bottom of each invoice. This piece count is used; to determine truck requirements, assigning personnel to select merchandise and checking merchandise into retail stores. ti 5Personal interview with Norman Powers, IBM representa- ve. 84 An additional advantage accruing to Overton‘s will be a reduction in cost as compared to the manual procedure employed. The pricing of ten orders at cost and retail represented a weekly cost of approximately $190.6 Under the IBM method, the same functions could be performed for approximately $77.7 Location of Merchandise Within the Warehouse Specific or fixed slot. The fixed slot system will be used for high volume items. Floating slot. The floating slot system is to be used for seasonal, special promotional and slow moving merchandise. Advantages of the floating slot.8 1. Automatic stock rotation is achieved. 2. Merchandise received for special sales promotion is placed in the warehouse without assignment of a special area. 6This cost was provided by Mr. A. W. Overton. The cost is based on wages paid and supplies used in the pricing function. The rate per hour for each employee was multiplied by the number of hours each employee devoted to this function. 7This cost was derived by dividing the rate per month for the complete IBM Tub File installation by four to achieve the weekly cost. This figure was divided by total weekly Operating hours. The cost per hour was then multiplied by nine. This figure also includes the cost of supplies and labor. The rate per hour paid IBM Operations was multiplied by nine representing the time required to pull the grocery orders each week. 8Powers, op: cit. 86 loaded pallets from the receiving docks to the storage areas by a high lift fork truck. The high lift truck would be used to vertically store merchandise in the storage areas as well as along the selection line. The equipment necessary to accomplish the receiving function is: 1. One low lift truck to transfer loaded pallets to the receiving dock. The cost of this truck is approximately $3,000. 2. One stand—up reach type high lift truck that will Operate in a six foot aisle. The cost of this truck is approximately $4,000. This truck will be used to transfer and vertically stack merchan- dise in the reserve area and along the selection line. 3. Pallets. The palletized program will be built around a 32" x 40”, two—way, non-reversible, hard- wood pallet. Pallets cost approximately $2.50 each. Dock facilities for receiving and shipping merchandise. The structural facilities at Overton‘s Distribution Center do not provide separate docks for receiving and shipping merchandise. Separate receiving and shipping docks are desirable to: l. Prevent conjestion and the resulting inefficiency. 2. Simplify the scheduling of deliveries. 87 3. Achieve an efficient relationship between the internal Operation of the distribution center and the activities performed in the receiving and shipping areas. (See Appendix D, page 117.) 1 Order selection. The most efficient order selection system can be deveIOped through the use of four wheel hand trucks and a tow unit, which offer: 1. Greater flexibility, 2. Greater productivity, and 3. The cost of this system is reasonable. The type and function of the equipment used to accomplish the order picking function would include: I. Pallet Racks--Racks should be installed to deveIOp a selection line for pallet loads. The racks will be used to achieve full utilization Of the cubage without sacrificing selection. 2. Shelving--Shelving is used in the small goods area to further develop the selection line. 3. Pallets-—The 32” x 40” pallet would also be used in order selection. A. Four Wheel Trucks-—These units would be used to achieve mobility in the order picking function. The cost of each unit would be approximately $120.00. 5. Tow Truck--This tow truck would be used to transport four wheel trucks along the selection line to the marshalling area.lo lOThc marshalling area is a portion of the distribution center used to assemble retail store orders prior to loading. Orders will be divided with segments with one man selecting each segment. Empty pallets will be placed on four wheel trucks located along the selection line. The order picker selects the items and places each case on a pallet. The four wheel truck will be pulled by a tow truck along the selection line to the marshalling area or to the shipping dock if delivery equipment is available. The fork lift truck will be used to load the trucks. A prOposed work schedule is provided in Table XVII. This table is based on the following figures: Average number of cases shipped each week-—1A,OOO Average number of cases selected per hour, per man—-90 Number of hours necessary to accomplish order selection approximately --l56 TABLE PROPOSED WORK SCHEDULE Number Of Hours Shipping Devoted to Number of Number of Days Order Selection Order Pickers Cases Selected Thursday 8 2—1/2 1,800 Friday 9 A 3,2AO Saturday 9 A 3,2A0 Monday 9 A 3,2AO Tuesday 8 2—1/2 1,800 Wednesday A 2 720 Delivery equipment. Under Overton's Operation, the rolling equipment consists of eight straight trucks. How— ever, the capital investment and Operating cost of rolling 89 equipment could be reduced by the use of larger tractor- trailer units. The present rolling stock represents a total capital investment of approximately $57,1AA.80. The total cost is explained as follows: #32,000.00——Cost of eight trucks when new $18,720.00—-Labor cost of six full time drivers at a weekly cost of $60.00 each $ A60.80—-State and city license $57.60 per truck $ l,A6A.OO—-Insurance coverage, $183.00 per truckll $ A,500.00——Operating cost12 $57,1AA.80-—Total The present rolling stock should be replaced with two tractors, four trailers, and one straight truck. The factors leading to this recommendation include: 1. A total piece count of merchandise shipped from the distribution center weekly. 2. The case capacity of each trailer. 3. The time necessary to load and unload each trailer. A. The delivery time to and from each store. ler. Bradley Spencer, Commercial Insurance Agency, Portsmouth, Virginia. This includes $100,000 coverage upon injury to one person, $300,000 coverage for one occurrence involving more than one person; $25,000 prOperty damage. 12The Operating cost includes gas, oil, tires, repairs, and depreciation. Operating cost figured on a per mile basis of 15¢ and then multiplied by total yearly milage of 30,000. 90 5. The number of stores requiring the Spotting of a trailer. 6. Allowance for equipment breakdown. The total cost based on the previous recommendations would be approximately $40,793.76. This cost is explained as follows: $12, $12, $ 1) $ $7, $32, $ $4, 000. 000. 152 185. 750. 000. 183. 57. 00 —— 00 _- .00 -— 48. 800. 00 —— 00 -- .98 —— .00 -- l8 -- 00 -— 00 -- 00 -— 00 -— $40, 793. 76 -- Cost of four 35 foot single axel trailers (3,000.00 per unit) Cost of two model 1800 International Tractors with 342 cubic inch and heavy duty clutch and rear end License, $576.00 per tractor License, $12.00 per trailer Labor two drivers, $75.00 per week Insurance, two tractors $257.49 Insurance four trailers (10% of cost of tractors $25.75) Approximate Operating cost of tractor— trailer units 3 Operating cost of straight truck Cost of one straight truck Insurance License Total 13This is an approximate Operating cost based on the following information: Case capacity of straight truck, approximately - 500 Case capacity of tractor—trailer, approximately 1200 Total cases shipped from distribution center per week, approximately 14,000 Number of straight truck loads per year —— 1,456 Number of tractor—trailer loads per year-- 624 The average number of miles traveled per load is 206. This 91 Yearly Operating cost for tractor trailers will vary in accordance with the number of orders placed on each unit. For example, if only one order is placed on a trailer the average distance would be 20.6 miles. If two or more orders are placed on a trailer the total yearly Operating cost would be increased at the rate of seventeen cents per mile. However, if deliveries are prOperly scheduled operating cost will not significantly be affected in Overton’s Operation. The function of scheduling is facilitated under the present Operation since each store invoice contains a total piece count figure. This figure could be used by the warehouse supervisor in determining routes and truck requirements. The one straight truck prOposed under this program would be used to deliver ”fill in” orders or to complete regular deliveries when the quantity of merchandise to be shipped does not warrant a trailer. The actual yearly Operating cost would be difficult to determine since the mileage would vary from week to week. However, based on the maximum use of the straight truck under the present Operation the yearly Operating cost would be $750.00. .figure was derived by dividing the total yearly mileage (If 30,000 by the total number of straight truck loads per’year. qnle average mileage of 20.6 multiplied by 624 provides a bfiearly mileage for tractor trailer units of 12,854 ‘T‘xg. ' ~o .. 1,. . Cwn-rating cost r»; 71;: .1 :. 92 The tangible savings realized from the use of tractor- trailer as Opposed to straight truck is approximately $16,351.04. This savings does not include such intangible factors as employee fringe benefits. Placement of merchandise in the delivery trucks. The merchandise would be placed according to the location of the retail stores to be served. Under this system the last order to be delivered is the first order to be placed on the truck. Fish nets would be used to separate each order. Warehouse Inventory. Based on the use of IBM a physical inventory should be taken semi—annually. A physical count at the end of each six month period is adequate to provide: 1. A check against the IBM system in relation to the perpetual inventory. This will uncover errors which have been made in processing merchandise through IBM, or errors which have occurred in the distribution center. 2. The information necessary in determining the financial status of the company and in deve10p- ing the financial statements as required by law. However, the author does not rule out the advisability of Spot check of stock as a safety precaution. 93 Checking merchandise into the warehouse. A complete check of all merchandise is necessary to insure correct receipts. After the check has been completed the receiving clerk signs the delivery ticket and requires the endorsement of the transportation agent if exceptions are noted. Checking merchandise from warehouse into stores. The use of the IBM equipment facilitates using a piece count by supplying the total number of units invoiced. Warehouse security. The warehouse security is primarily the responsibility of the warehouse foreman. However, the assignment of Opening and closing the ware— house, turning on and off the lights and securing the trucks to the qualified members of the warehouse crew is recom— mended. Summary Procurement of merchandise. The IBM method of Inventory Control and Accounting is recommended based on the following advantages: 1. Better inventory control. 2. Increased stock turnover. Automatic store billing. Invoice lists items according to warehouse layout. Stock outs are not billed. Warehouse efficiency increased. Buying signals. CID-\JmU‘I-P‘U) Better accounting reports on sales and profits. 14'." ""“‘m- ...-m-: ...- 94 Special promotional merchandise. Promotional mer- chandise should be handled in the warehouse only when the cash discount is large enough to defray the handling cost, and when the minimum order size meets minimum stock turn requirements. The only exception to this rule might possibly rest in realization of a reduction in freight charges imposed when merchandise for several stores is delivered to one location. This may be termed "extra service” performed for the retail stores. DrOp shipments. The use of drOp shipments should be limited to those items requiring daily delivery and ser- vice or special promotional merchandise. Ordering merchandise by stores. The IBM printed order form is recommended for ordering merchandise from the warehouse. This system is recommended because: 1. Order forms are printed every four weeks, there- by assuring the store manager of a complete and correct listing of merchandise available. 2. Space is provided for store ordering history. 3. Printing and mailing costs are reduced. Order scheduling. The factors to be considered When deveIOping rules related to the receipt of store orders are: 1. Size of the orders. 2. Number of orders per week. 3. Size of work force. 4. Availability of storage and dock facilities. 5. Order filling speed. The order picking function will be scheduled to coincide with the receipt of store orders. Location of merchandise within the warehouse. The use of the fixed slot for high volume items and the float- ing slot for low volume items and items affected by seasonal variations is recommended. To achieve this the selection line would be divided into two sections. Receiving and shipping merchandise. Pallets and fork lift trucks 1:; rec~¢rerial for the following reasons: 1. The adaptability of the pallet and fork lift truck to the structure under consideration. 2. The Operations of the pallet and fork lift truck system is economical and efficient. 3. More efficient use of Space is possible. 4. Shipping and receiving can be performed simultane- ously under the palletized system. Placement of merchandise in the delivery trucks. The placement of store orders according to the location of the retail outlets to be served using fish nets to separate orders is recommended. Warehouse inventory. A physical inventory every Six months is recommended. 96 Checking merchandise into the warehouse. A complete check is recommended to insure the correct receipt of merchandise. Checking merchandise into stores. The total piece count figure provided by IBM offers store managers an economical check of merchandise received from the dis— tribution center. Warehouse security. The warehouse foreman must assume the final reSponsibility in all matters involving the warehouse security. CHAPTER VII CURRENT AND PROPOSED OPERATING PROCEDURES OF OVERTON S DISTRIBUTION CENTER The purpose of this chapter is threefold: 1. To summarize the systems employed by Overton's at the inception of this study. 2. To discuss recommendations related to changes in the distribution center. 3. To consider the results, both realized and anticipated, of these recommendations. Changes have occurred in the distribution center since the inception of this study. Therefore, the preceding points will be discussed under two broad classifications: (a) Current operating procedures. (b) PrOposed operating procedures. Current Operating Procedures The decision by management to initiate changes in the food distribution center Operation resulted from an analysis of the information secured in this study. That is, the economic feasibility of a change was proven by the successful acceptance of the systems by companies of Comparable size and volume. The first classification in which a change has oczcurred is in the procurement of merchandise. The IBM tiib file method of inventory control has been installed. 'IWiis system is being used by Overton's to: 1. Print order forms every four weeks for retail stores. Print invoices for retail stores. The use of IBM in the invoicing function has, reduced the 14 reduced the time necessary 15 and reduced the personnel required, to accomplish this function, possibility of error by reducing the extent of dependance on the human factor. Provide perpetual inventory information. Provide warehouse stock movement information. One Of the most significant deveIOpments resulting from this system originated from the movement analysis report. The inventory of one department was reduced from $45,000 to $25,000, in six months. The factor accounting for this inventory reduction was a stricter control over quantities purchased. The movement analysis report provided the information to accomplish this in addition LUnder IBM, one full—time and one part—time employee Eire used. 2Approximately 18% of the time is devoted to in— \/oicing under IBM. Mr. A. W. Overton stated that from SC) to 100% of the time of each employee was devoted to iIIVOiCing under the manual procedure. to being helpful in buying new items and discontinuing old items. In conjunction with the application of the movement analysis report to a program of discontinuing items, the following procedure has been adopted. Since March 15, 1963, IBM movement reports have been sent to each store manager. Each store manager was asked to check those items which should be continued despite poor movement figures. One—half of this program has been completed and approximately 500 items have been discontinued as a result of these findings. The grocery buyer also uses this movement report in buying new items.16 The procedure followed involves a study of the movement of a similar item already stocked in the distribution center. U7 Printed price change reports and new item listings are sent to the stores weekly. This enhances the flexibility of the system by facilitating the immediate distribution of new merchandise and by keeping retail prices current. The approximate weekly cost of providing the fore- goixmginformation is $144. This is less than pricing the 3The grocery buyer replaced the buying committee previously used in purchasing new merchandise. 100 orders at cost and retail under the manual system pre— viously employed by Overton's. Special promotion merchandise. The curent system continues to use special orders. However, if the cash discount is large enough to cover handling cost, the mer- chandise is handled through the distribution center. This is to effect economics in freight charges and to reduce the f time and personnel necessary to handle store door deliveries. é DrOp shipments. The original policy established by g Overton's limited this procedure to those items requiring E daily service and delivery. This is being continued and [_fl has been expanded to include those items which can be ordered economically in quantities that will provide a 1 stock turn every two weeks. Receiving merchandise. The use of pallets and fork trucks has resulted in greater utilization of warehouse facilities. The increase in warehouse utilization has for the first time placed management in a favorable position for deveIOping additional business without an accompanying increased investment in building. The number of employees actively engaged in the warehousing function has been reduced from seven to four. This reduction in personnel has been made possible due to: l. The use of the palletized system in receiving. 2. The increased selectivity of merchandise in the order picking function. 101 The cost of installing the palletized system was approximately $24,000. This cost includes pallets, pallet racks, and one high lift truck. Dock facilities. The current Operation involves the use of separate facilities to accomplish shipping and receiving. The results have been a smoother flow of merchandise into and out of the distribution center. The dock facilities have been located to coincide with the internal functioning of the distribution center. All receiving is done in the storage area and all shipping is limited to the order picking area. Ordering merchandise by stores. The current procedure involves the use of the IBM catalogue to order merchandiSe. The store orders must be in one day in advance of delivery. Checking merchandise. The procedure followed in checking merchandise into the distribution center remains the same. Store receiving is checked by piece count pro— vided on the IBM invoice. The total piece count method offers Overton's a fast and economical check of merchandise and an assurance that losses due to imprOper receipt of merchandise are at a minimum. Warehouse inventory. NO change in taking a physical inventory in Overton's distribution center has been made. Warehouse security. The responsibility for the security of the distribution center is delegated to mem— bers of the warehouse crew, with the warehouse manager 102 reSponsible for seeing that the security measures are prOperly performed. PrOposed Operating Procedures Order selection. Store orders continue to be selected by teams of from three to four men. Delivery equipment. Eight straight trucks continue to be maintained by Overton's Markets. However, recently Mr. A. W. Overton negotiated with a transportation company F to rent tractor trailer units for the larger store orders. This procedure involves the Spotting of empty trailela at the distribution center and the subsequent removal of the loaded "““1 rsto the retail outlets. This procedure k'...

Ebonclusion The purpose of this study has been to deveIOp and Iwecommend a system which when applied to Overton's Food Dixstribution Center would affect a more economical and efifificient distribution of merchandise. This study has beuen helpful in that many of the recommendations have been Enjoymed with favorable results. Additional changes are lilanned.
