Application of Cycle-Based Simulation to Estimate Loss of Logistics Productivity on Construction Sites
Logistics management is a critical factor that determines the successful delivery of a construction project. The logistics activities have close connection with other logistics/construction activities, often producing hazards on site. Moreover, the policies and measurement taken to prevent these hazards often decrease the productivity of logistics activities. Therefore, quantitative evaluation of the influence of dynamic hazardous interactions between logistics/construction activities is critical for estimating the logistics productivity on situ. Unfortunately, previous research is inadequate in evaluating the contribution of dynamic hazardous interactions to the logistics productivity loss. This study develops a cycle-based simulation model for abstracting dynamic hazardous interactions between two logistics/construction activities, and then presents an algorithm for computing productivity loss. Consequently, the work delay of logistics activities can be better estimated and understood by site planners. In particular, the results of the case study indicate that the fluctuating characteristics of both logistics and construction activities in the same cycle significantly affect the logistics productivity loss.
