Research On Robust Design For Food Supply Chain System

The purpose of this research is to robust design for food supply chain system. As complex social and economic system, with the increasingly fierce competition and increase economic uncertainty, consumer demand's personalized and diverse and rapid environmental change, food supply chain management has a lot of uncertainty factors that are difficult to manage the main obstacle. Robust design is the purpose of reducing uncertainty for the negative influence of supply chain performance, and optimizing supply chain so as to improve the competitiveness of enterprises, so there has important theoretical and practical significance.Firstly, this paper introduces the background and significance of research, and expounds and summarizes the current research status of related field, then we analysis two kind of common robust design method, and carries on the comparison, summarizes their respective advantages and disadvantages. Dual response surface method has a high repeatability in text and calculation, and for high uncertainty factors,it has a certain binding on the choice of factors quantity and testing time. Based on this kind of situation, this paper provides improved dual response surface method, meanwhile, through detailed analysis of the uncertainty of food chain, the author ensures the influence factors of the robustness on the system, finally we uses the improvement of dual response surface method, and realizes the robust design for food supply chain system, and obtain a robustness optimization solution. We comparises the robustness solution and the robustness optimal solution for response surface method through the numerical experiment, then it verifies the effectiveness of the improved dual response surface method.This innovative work has the following basically:1. This paper presents an improved dual response surface method. We improved the dual response surface method in robust design, which analysis uncertainty factors comprehensively and flexibly, and finally to obtain more robustness results, so this method makes up some shortcomings.2. This paper enriched robust design theory in complex food supply chain field of applied research. This paper comprehensive and systematically analyzes characteristics, influence factors on the food supply chain system and the uncertainty factors what have an important impact on the system. How to resolve the supply chain performance problems through the robust design method and related theory. Moreover it rich the theoretical research achievements for robust model of supply chain system design.3. In this paper, we make a quantitative analysis for the uncertainty of problem on the food chain, and it can more thoroughly solve the uncertainty impacts for the food supply chain.
