Cue-based decision-making in construction : an agent-based modeling approach
ABSTRACTCUE-BASED DECISION-MAKING IN CONSTRUCTION JOB SITES:AN AGENT-BASED MODELING APPROACHByAli LahoutiA construction worker often faces ambiguities as he/she executes an operation to deliver an assigned task. Ambiguities may be induced by a broken communication process (e.g., an incomplete construction drawing; an implicit verbal instruction), in which a recipient (e.g., a skilled trade worker) does not receive perfect information and explicit instruction. In such circumstance the receiver of this imperfect information is required to make a judgment on `what-to' do and `how-to' do it.This investigation suggests that the more perfect/explicit the instruction is the more efficient the execution will be - measured in terms of the reduced task duration and need for re-work. Perfectness and imperfectness of an instruction in this study is distinguished based on whether it is an explicit signal (e.g., a solid red traffic light) as opposed to an implicit `cues' (e.g., an alternating orange/green blinking traffic light). This hypothesis is evaluated based on impact of these two instructions types on performance efficiency of a construction skilled trade worker while executing an assignment.An Agent-Based Modeling (ABM) approach was employed and different types of instructions were introduced to an agent. The outcomes suggest that performance efficiency is correlated with level of instruction provided which can improve performance efficiency up to 78 percent.
