Simulation and Optimization of Loading and Unloading Operation System in Port Logistics Park Based on Arena

Port Logistics Park is a complex dynamic stochastic system. It consists of berths, container, ship, yard, cranes, transportation machinery, roads, parking areas, vehicles, staff and other elements which constraints and interacts with each other. Each of the operations within the port logistics park has the characteristics of discrete random. The ship arrival time, vehicle service time, facilities service time are all random and dynamic. Therefore, such a system is difficult to describe and evaluate by using conventionally single mathematical model. In this thesis, using Arena simulation software combined with loading and unloading system in port Logistics Park. Established model of loading and unloading operations and set the parameters related, in order to simulate the loading and unloading system of the port logistics park. By analyzing the simulation results, to adjust the parameters so that the waiting time and quantities are lower and the utilization rates of facilities are at a high level. At the same time, the total cost of the system is the lowest. The final objective is to work out the optimal loading and unloading system.
