- Abstract:
-
Traditional resource-constrained project scheduling problems (RCPSPs) can hardly meet current practical needs. Hence, expanding the RCPSP is an inevitable trend. Therefore, this paper abstracts the original RCPSP problem based on the characteristics of dynamically releasing maintenance tasks for equipment, adding multimodal resource allocation issues related to equipment. Thus, a multimode dynamic resource allocation and scheduling model for multiple maintenance centers is established. This paper proposes a hybrid optimization algorithm combining genetic and long-nosed raccoon algorithms to solve the proposed model effectively. The algorithm is added with the selection, crossover, and mutation operators of the genetic algorithm based on the original coati optimization algorithm, which are mainly used to expand the search range, thereby jumping out of local optimization. Furthermore, greedy operator functions are added to further improve the quality of candidate solutions. Comparative analysis of the results of simulative experiments revealed that the newly proposed genetic long-nosed raccoon hybrid optimization algorithm is superior to other algorithms in terms of convergence speed and solution quality.
