Research On Supply Chain Of Transmission Line Project Based On System Dynamics

Transmission line engineering supply chain is one of the supply chain, which is composed of raw material suppliers, production and processing enterprises, transportation system and owner. In transmission line construction supply chain, each link is linked together closely, once a part of products manufacturing, information transfer or transport of unexpected, have a serious impact will be on the link of the whole supply chain, resulting in supply chain risk greatly increased, serious when can also affect the transmission line project time limit for a project, quality, safety and progress of. And because the transmission line engineering in the construction of the time is often selected in the sparsely populated, the environment is poor, which leads to the long line, the construction is difficult, the construction environment is bad, the time limit for a project. These characteristics determine the transmission line project supply chain has a lot of risk.In this paper, we focus on the system dynamics theory to carry on the risk of transmission line engineering supply chain risk, the main research contents include:(1)This paper first introduces the research background and significance of the research,and the study of the relevant theoretical knowledge of the supply chain risk and system dynamics, based on the basic content and characteristics of the supply chain, the principle and content of the project supply chain risk management and the basic theory of the system dynamics.(2)This paper studies the application of system dynamics theory in risk identification of transmission line engineering supply chain, analyzes the traditional risk identification method and its shortage. The system dynamics is applied in risk identification of transmission line engineering.(3)This paper establishes a risk feedback loop based on the risk identification stage,establishes the system flow chart of each sub system, evaluates the risk, including the risk assessment model, and establishes and runs the feasibility of the system dynamics in the risk assessment.(4)This paper introduces the risk identification and risk assessment of transmission line engineering supply chain. Based on the theory of system dynamics, the risk control of supply chain is carried out.
