Research On Supply Chain Performance Of Fresh E-Commerce Based On Rough Sets And Fuzzy Comprehensive Evaluation

In recent years,with the rapid development of e-commerce and the change of people's consumption behavior,the fresh e-commerce is rapidly spring up.Fresh products are different from traditional industrial products,"easy to rot away,not easy to store" is the inherent attribute of it.The development of fresh e-commerce and cold-chain logistics provides the basis for efficient circulation of fresh products.But in fact,in the circulation process of fresh products,often due to the various uncertainties of each link,it's often unable to achieve the products value,the enterprise engaged in fresh e-commerce and its upstream and downstream enterprises not only unprofitable,but also face and bear a lot of risk.Supply chain management has become the consensus to reduce costs,to reduce risk,to improve profitability and to enhance the competitiveness for fresh e-commerce sector.Fresh e-commerce supply chain performance evaluation is an important part of the supply ch ain management,which can effectively identify the supply chain operation level and provide decision support for its performance improvement.Therefore,it is of great significance to establish a set of performance evaluation index system suitable for the development of fresh e-commerce supply chain.The following research has been done in this paper to the performance evaluation of the e-commerce supply chain as follows: Firstly,systematically reviews the fresh e-commerce supply chain characteristics and related content,put forward the fresh e-commerce supply chain mode with fresh e-commerce platform as the core,at the same time,summarize the related theories on supply chain performance evaluation;Then,based on the above research content and related t heories,from the perspective of fresh e-commerce platform enterprises,combine with the fresh e-commerce supply chain's "product characteristics","e-commerce characteristics",based on the BSC model,from the six dimensions of "products,e-commerce ability,financial,customer,operation process,learning and growth ",systematically construct the system of performance evaluation index of fresh e-commerce supply chain,comprehensive consideration of the factors influencing the performance of fresh e-commerce supply chain;Next,combined with the characteristics of fresh e-commerce supply chain,construct the performance evaluation of fresh e-commerce supply chain model based on rough sets and fuzzy comprehensive evaluation model,using rough set theory to the evaluation index redundancy in the evaluation system of reduction and determine the weight of each index of each corresponding attribute,then use fuzzy comprehensive evaluation method to evaluate the performance of fresh e-commerce supply chain;Finally,the calculation and analysis are carried out with specific examples,and some suggestions and countermeasures are put forward,and the validity of the model is proved.This paper provides new ideas and methods for the performance evaluation of fresh e-commerce supply chain.
