Production-distribution Planning in Supply Chain Management under Fuzzy Environment for Large-scale Hydropower Construction Projects

摘要

In this paper, production-distribution planning in construction supply chain management is presented under fuzzy environment. This paper specifically addresses bi-level decision making problem with lower level corresponding to a plant planning problem, while the upper level to a distribution network problem. The main targets of the upper level are to minimize cost and maximize the satisfaction level for concrete mixing plants. The targets of the lower level are to maximize the profit and customer satisfaction level. The model is formulated in terms of fuzzy programming and the best solution is provided by using the fuzzy simulation and sensitive analysis is used to highlight the results. The Neelum Jhelum Hydropower Project is used as a real-world example to illustrate the effectiveness of the proposed approach.
