Abstract

In this paper, a methodology for reinforcing sustainability in supply chain (SC) model is proposed. For the sustainability, economic, environmental and social issues are considered in the SC model which consists of various facilities at each stage. Each issue considers i) the minimization of total cost, ii) the minimization of total amount of CO2 emission and iii) the maximization of total social influence. The SC model with reinforced sustainability is represented as a mathematical formulation and implemented using a hybrid approach. In numerical experiment, two scales of the SC model are presented and the performance of the proposed hybrid approach is compared with those of the some conventional approaches. The experimental results show that the proposed hybrid approach is more efficient than the competing approaches.
