Conflict resolution towards an integrated project scheduling and material ordering system in a large-scale construction project. (English) Zbl 07139896
Summary: This paper emphasizes a novel integration of project scheduling and material ordering (PSMO) under a fuzzy random environment, which provides more flexibility to the project scheduling and considers additional trade-offs between these two issues. Hence, a novel Stackelberg game model within bi-level multi-objective programming is developed to examine the inherent conflicts and interactions in the integrated PSMO, in which the project scheduling problem (PSP) is the upper-level programming, while the material ordering problem (MOP) is the lower-level programming. To search for the optimal equilibrium strategy, a bi-level hybrid algorithm combined of particle swarm optimization (PSO) and genetic algorithm (GA) is developed. Finally, the applicability and efficiency of the proposed optimization methods are evaluated through a practical large-scale construction project.
