Multi-Mode Resource Investment Project Scheduling Problem Based on Project Splitting

Abstract:

Combined with a class of actual production decisionmaking needs, a multimode project scheduling problem based on project splitting decision was proposed. In order to minimize the resource investment, an integrated optimization model including project splitting and multimode resource investment model was build. Considering the characteristics of the model, a doublelayer optimization algorithm, including project splitting algorithm and multimode resource investment project scheduling algorithm, was presented. The project splitting algorithm obtained a reasonable resolution scheme by moving jobs among different subprojects and the multimode resourcebased project scheduling algorithm determined the priority rules by analyzing the influence of different jobs on time constraints and resource constraints. The data experiment was carried out by using the Project Scheduling Problem Library(PSPLIB) standard example. Results validated the algorithm.
