Abstract [en]

Simulation is an effective quantitative analysis tool to compare and evaluate different system design. However, the application of simulation in construction industry has been limited to relatively restricted research fields. This paper presents a discrete event simulation (DES) model using in which quantitative performance evaluation between constant work-in-progress (CONWIP), a pull method that limits the work-in-progress (WIP) level in the production system according to the status of system, and push are provided. A card element in the simulation model is used to authorize the production, collect cards and limit work-in-progress (WIP) level in the system. The purpose of such comparison and evaluation is to explore the utilization of DES and CONWIP on inventory control.Uncertainty and variation in construction process has an important influence on project performance. The common practice to deal with variation is the holding of inventory. As demonstrated in developed simulation model in this research, suitable inventory improves the performance of project. However, excessive inventory induces no-added value. Simulation experiments show that application of DES and CONWIP provides an effective way of inventory control, simultaneously, maintain throughput and cycle time compared to push system. The research will be of interest to those evaluating the impacting of lean base method on construction project performance with simulation.Keywords: DES, inventory control, lean, CONWIP
