Research on Resources Integration of Urban Distribution System based on System Dynamics

Abstract

Resource of urban distribution system is a typical distributed network structure and the goal to integrate the resources of urban distribution system is to maximize the system value. This paper carries out an in-depth analysis on urban distribution system by the methodology of System Dynamics. The modeling and computer simulation are given after the dissection of system boundary, main system factors and system causality. The simulation shows that, to achieve the desired integration level and to improve the resources owners' efficiency, optimal the exogenous environment and introduce more favorable polices are both feasible, but to the other two factors, physical resources factor only effect the resources owners' efficiency and the coordination mechanisms factor impact none. 1. Introductions With the rapid changing of modern production modes, commercial activities and consumption patterns, urban distribution is getting more and more important, and it has already became an indispensable part of urban economic system. In the past few years, urban distribution system is gaining independence from urban logistics system gradually, it showed significant system characteristics in nowadays. As a key component of urban distribution system, urban distribution resources refer to all the imputing things which aim at achieving urban distribution system goal, it not only includes the narrowly speaking resources, such as capital, technology, knowledge, information, human resources, premises and facilities, but also includes the generalized resources, such as distribution organization, distribution institution and the relevant laws or regulations. In current urban distribution system, there are many prominent problems, such as vicious cycle between urban distribution resources inputs and its efficiency, unclear situation of resources owners' microscopic behavior and the immature of urban distribution market mechanism, these phenomenon have restricted and now is restricting the developing of the urban distribution system seriously. In addition, urban environmental pollution, urban traffic congestion, traffic accidents and other environment problems are inextricably linked with urban distribution activities, these problems have become a serious impediment to the overall development of modern urban. By reasonable configuration of decentralized urban distribution resources, we can achieve the organic integration and 1+1>2effect goal, and in this way we can improve our urban living environment. So research in the resources integration issue of urban distribution system has an important practical significance.
