Review of Cost-Oriented Maintenance Resource Allocation and Task Scheduling Problems

The maintenance of complex equipment typically involves considerations such as cost control, resource allocation, workflow constraints, task mode selection, and maintenance deadlines, making it a complex resource-constrained project scheduling problem. This article first elaborates on the background of cost-oriented maintenance resource allocation and task scheduling. Next, it reviews and analyzes the current research status of related areas, including resource-constrained project scheduling, multi-project resource leveling, and resource allocation cost problems. Finally, potential future research directions are discussed.
