Analysis of Urban Distribution Capacity System Based on Vensim

With the rapid growth of urban distribution, there are many problems that can culminate, including traffic congestion. Based on system dynamics theory, this paper constructs a dynamics model of urban distribution capacity system using systemic thinking, in which the model contains a social subsystem, vehicle subsystem, and environment subsystem. A cause-effect loop diagram is drawn and clarified by Vensim software to sort out the relationships and logical loops within the subsystems. Its purpose analyzes the factors affecting the change of distribution vehicle capacity and correlates it between the elements within the total system of capacity. For urban distribution in China, it is necessary to use the concept of sustainable development to establish the concept of green distribution into practice and implement it into the actual distribution work, so as to bring about the long-term development of the distribution economy.
