Outline

This paper presents a resource-centric modeling and solution framework (REMS) for formulating diverse combinatorial optimization problems (COPs) as a unified paradigm and designing reusable metaheuristic algorithms. REMS decomposes a COP into resources and tasks, and constructs a problem model by deriving variables, objective functions, and constraints based on a unified solution structure that assigns tasks to given resources. Based on this unified solution structure, we design basic operators such as initial solution, neighborhood structure, destruction and recovery, crossover, and ranking, and develop various metaheuristic algorithms. We validate the effectiveness of REMS through experiments on ten diverse COPs (including routing, location, loading, assignment, scheduling, and graph coloring) using four single-point-based algorithms and one group-based algorithm. We demonstrate that REMS outperforms GUROBI and SCIP on large-scale and complex COP problems, and outperforms OR-TOOLS on some difficult COP problems.
