Research On Supply Chain’s Emergency Logistics Decision Under The E-commerce Environment

With the rapid development of information and communication technologies, e-commerce as a new business concept and mode of operation, is gradually penetrated into all aspects of people’s daily life, is the traditional market opened up a new operational approach, and constantly increase the size of. The market is whether online or offline( "virtual market")( "actual market"), there is competition everywhere, companies are also increasingly fierce competition, the selection of suppliers from the beginning, the number of types of goods competition, to face object of consumption, distribution and service competition, price war to end, in the final analysis is the competition of the supply chain. The ever-changing environment in which e-commerce, e-commerce in the legal regime governing China is not perfect, if you manage to ignore the excessive pursuit of economic social benefits, ignoring the risk of emergency management to make wrong predictions and determine the cause of e-commerce supply chain, there is a big risk.According to statistics, in 2014, taobao network shopping platform in the double tenth of a turnover is 57 billion yuan, and in 2015 reached 92 billion yuan. Faced with such a huge order demand disturbances would have a significant impact on the supply chain, each enterprise inventory, transportation goods, orders the owner of the network of goods, delivery of goods suppliers, logistics service levels. Faced with such a huge increase in demand, suppliers how to procurement, production, planning, dealers how to order, how to adjust inventory, distribution centers how fixed, regular, quantitative and ensuring service levels to meet the needs of the case of the transport of goods to the hands of consumers, and slowly attracted the attention of scholars.To read about the electricity supplier supply chain logistics, emergency management literature and statistical data relating to the electricity supplier supply chain is the basis to determine the supply chain logistics is constraining the development of China’s e-commerce bottlenecks, logistics, backward technology, low level of logistics services, logistics services quality can not meet the requirements, leading e-commerce struggling. Therefore, the choice of e-commerce supply chain contingency as a research topic is crucial. This paper describes the use of systems thinking on supply chain logistics under electronic commerce background process, and on each node upstream and downstream e-commerce supply chain including suppliers, dealer network, network consumer, logistics services business, e-commerce platform, and its processes and theoretical introduction. On this basis, in view of the system, for even the supply chain logistics system, the system boundary and causality analysis, using the theory and methods of system dynamics to establish e-commerce supply chain logistics system model, and operates in accordance with its sales data, Vensim software made use of this model more experimental program to improve the supply chain logistics system in normal mode and emergency situations are simulated, the simulation results and improving strategies for analysis, rationalization proposals.
