| As well as the most cumbersome and time consuming link of logistics distribution center, sorting system is the core of distribution center. Reasonable allocation on sorting system plays a decisive role in meeting the requirements and improving service levels of logistics distribution center.Based on the combined Agent and UML, and taking the sorting system in a logistics distribution center in Nanjing as the research object, the author sets up the static and dynamic models for every operating procedures of logistic sorting system.Some operation procedures in sorting system are simulated with the logistics simulation software——Flexsim. The author finishes the computer stimulation of sorting system. According to the results of simulation, some problems are found and relevant improvement measures are put forward.The author puts forward the research approaches used to study the sorting system by Agent and Flexsim. Those approaches are also applicable to other dynamic and stochastic systems in the field of logistics, and provide a theory reference and practical foundation for designing and evaluating logistic system. |
