Simulation is one of the most important methods utilizing models to study system.Simulation technology has developed for nearly 50 years. It has been applied widelyand effectively in aerospace, military, automation, electric power and other fields. Withthe development of computer technology and in-depth research in all areas, systemsimulation technology is becoming more and more mature and its application fields areexpanding.Recently, more and more people are paying attention to modern logistics. It hasmany features, including wide coverage, comprehensiveness and broad involvement. Itcovers industry, agriculture and service industry, and it integrates a number of areas inmanagement and engineering. It involves many processes such as transportation,warehousing, packaging, service, information, and so on. Logistics is not only related to the enterprises' development, but also plays a vital role in the development of the national economy. Therefore, people pursue the common goal of promoting the transformation from traditional logistics to modern logistics. The research on introducing system simulation technology into modern logistics can assist people to scientifically plan and design logistics systems, control logistics operation process, and allocate logistics resources. It can promote the overall optimization of logistics system. At the same time, the vigorous development of the logistics industry will also promote the development of system simulation technology and open up a new field for the application of system simulation.
