A bi-level model for resource-constrained multiple project scheduling problems

Abstract

The aim of this paper is to present a bi-level model for the resource-constrained multiple project scheduling problems (RCMPSP). For the practical situation, the complex hierarchical organization structure and birandom environment are considered in the decision making process. For solving the bi-level model, improved particle swarm optimization algorithm is designed to obtain the optimal solutions. The results of an illustrative example are presented to highlight the practicality and efficiency of the proposed model and algorithm.
