Research On Improvement Of Supply Chain Protocol Inventory Of State Grid Corp Based On System Dynamics

In the era of economic globalization,it is increasingly important to for the supply chain management to be customer demand oriented and to take the resources-integration as an approach.As an industry closely related to national economy and security,it is crucial for the electricity sector to establish an effective supply chain management system.The new round of electricity sector reforms launched in March 2015 is changing the profitability model of China's grid companies.This will remarkably shift the company from single material management to supply chain management.In this context,it is important to examine how to build a domestically leading and internationally first-class supply chain management system for the State Grid.However,few existing papers have studied the supply chain management of the State Grid,let alone the supply chain model on the protocol inventory.of the company.Using system dynamics approach,this paper examines the inventory simulation of State Grid Corp supply chain.It firstly analyzes several methods of supply chain inventory management and the internal logic and thinking of system dynamics,and determines the applicability of system dynamics to supply chain inventory management;Then,it analyzes the status quo of the supply chain of the State Grid,and determines the material management based on the purchase model of the protocol inventory.Using CPFR(Collaborative Planning Forecasting and Replenishment)supply chain inventory management as an improvement method,taking the system dynamics as the research tool,the supply chain of the State Grid is improved.The supply chain is compared and analyzed before and after the improvement.In addition,the system dynamics modeling of the supply chain before and after the improvement is simulated to examine their inpacts on the stock quantity and the stock stability.At the end of the paper,recommendations on specific measures for the State Grid's supply chain inventory management based on CPFR is made.The main conclusions drawn from this study are:First,CPFR model,which is characterized by coordinated planning and information sharing,has applicability to the research on the supply chain management of State Grid Corporation.Second,compared with the traditional model,the average inventory of the material platform of State Grid Corp under CPFR mode is reduced by 13%,the variance is reduced by 35%;the supplier inventory is reduced by 14%,the variance is reduced by 20%;the manufacturer inventory is reduced by 41%and the variance is reduced by 16%.It proves that CPFR mode can stabilize the supply chain inventory Third,the CPFR management model can be applied in two aspects:(1)Establishment of supplier evaluation mechanism(2)Establishment of e-commerce system.
