چکیده انگلیسی


• A vehicle routing model is proposed to schedule periodic rail inspections.
• A customized heuristic algorithm is developed to effectively solve the problem.
• The proposed algorithm significantly outperforms state-of-art solution approaches.
• The modeling framework has been adopted in practice by a Class I railroad.

Railroads use a set of rail inspection teams to periodically examine the status of rail tracks across the railroad network. The rail inspection scheduling problem (RISP) is a large-scale routing and scheduling problem where thousands of inspection tasks are to be scheduled subject to many complex constraints. This paper proposes a vehicle routing problem formulation for RISP and develops a customized heuristic algorithm to effectively solve the problem. Real-world case studies show that the proposed approach significantly outperforms commercial solvers and the state-of-art manual solution approach. The proposed approach has been adopted by a Class I railroad to enhance safety and operational efficiency.
