Analysis and modeling of supply chain management of fresh products based on genetic algorithm

The important factor for the supply chain management of fresh products is partner selection. Environment protection is also an important factor, however the factor is not taken into account by the traditional supplier selection. Therefore, the supplier selection standard includes the green standard in this paper. Our work is to investigate an optimal mathematical modeling for green partner selection. The four targets of the proposed model are cost, product quality, green appraisal score and time. The proposed genetic algorithm with multi-targets are to search the set of optimum solutions using by weighted sum method. The proposed model introduces a supply chain network structure to analysis average number Pareto-optimal solutions with genetic algorithm for the four problems. It is pointed out that the variation of f(2) and f(3) with f(1) and f(4) is kept within obvious ranges. This practical result highlights the fact that the effects of the fact that effects of f(2) and f(3) are important factors affecting the performance supply chain network of fresh product.
