A Bi-level Programming to Two-Stage Transportation Planning Problem

This paper presents an extension of the two-stage transportation planning problem for a large scale hydropower construction project where bi-level programming and a balance of the satisfactory degree between decision makers are considered. For solving the complex and non-linear bilevel programming model, an interactive fuzzy programming technique and a particle swarm optimization with passive congregation algorithm are designed as a combined solution approach. Finally, the results and analysis of a practical example are presented to demonstrate the practicality and efficiency of the proposed model and optimization method.
