Simulation-Based Analysis of Construction Schedule

This paper presents a simulation-based network plan method aim at overcoming the defects of PERT in planning project schedule with uncertain activityduration.Dynamic simulation of the entire construction process is utilized to obtain the activity durations and project duration.As only basic simulation parameters such as geometrical shape and equipment type are needed the method avoids the difficulty in selection of stochastic function of activity duration in PERT.The construction duration,the completion probability of construction duration,and the critical index of activity are gained by statistical calculation of simulation results.Therefore,the reasonableness of construction duration and critical path are convincing.
