Study on Resource Allocate Of Container Yard Based on Simulation Optimization Method

A simulation optimization method was proposed to realize the optimal planning on resource allocate of container yard. The formulation of mathematical programming model was established. The optimal objective was to minimum the cost of resource allocation and ensure to maximum the utilization rate of resource. Considering the uncertain and stochastic activities in the system, the discrete-event system simulation model was built. To solve the planning problem, the simulation optimization method was proposed with the simulation model. An actual case was analyzed to illustrate the validity and correctness. The results from simulation optimization method were compared with traditional planning method and the advantage of this method is shown. Moreover, the sensitivity of this planning result was analyzed.
