Summary

Simulation is a crucial method in project management for analyzing the construction operations’ productivity and project schedules’ performance. The two level applications would be desirable if they are tightly linked to each other in practice. However, appropriate integration was not achieved. This paper presents a system, called Integrated Construction Operation and Schedule simulation (ICOS) system, which supports not only productivity analysis at operation level but also schedule management at a project level. The system allows creating operation models at the operation level, maintaining them in operation model library, executing sensitivity analysis to find the behaviors of the operation models when different combination of resources are used as existing DES systems do. ICOS facilitates to find the optimum solution of resource combinations which satisfy the user’s interest by computing the hourly productivity and the hourly cost of the operation. By drag-and-dropping an operation model kept in the operation model library, the operation models are integrated into an activity of the schedule model. When a complete schedule model is established by nesting operation models into the schedule model, stochastic simulation based scheduling is executed. A case study is presented to demonstrate the new simulation system and verify the validity of the system.
