A Fuzzy Chance-Constrained Programming Model for Liquid Chlorine Downstream Products Selection Problem in Environmental Services

Development of cyclic economy is not only an important part of environmental services, but also the inevitable choice to achieve sustainable development. China´s chlor-alkali chemical cyclic economy development mode focus on fine chemical industry. In this paper, fuzzy theory is applied, and a fuzzy chance-constrained programming model based on credibility measure for liquid chlorine downstream products selection problem is built for a chlor-alkali chemical eco-industrial park. And two methods are designed to solve the model. When the fuzzy variables are triangular fuzzy numbers, the crisp equivalent of the model are derived. When the model can´t be transformed into a crisp equivalent, a genetic algorithm based on fuzzy simulation is designed for solving the model problem. Finally, a numerical example is presented to illustrate the modeling idea and the effectiveness of the proposed algorithm.
