The vehicle routing problem with time windows (VRPTW) is an important problem in third-party logistics and supply chain management. We extend the VRPTW to the VRPTW with overtime and outsourcing vehicles (VRPTWOV), which allows overtime for drivers and the possibility of using outsourced vehicles. This problem can be applied to third-party logistics companies for managing central distributor-local distributors, local distributor-retailers (or customers), and manufacturers. We developed a mixed integer programming model, a genetic algorithm (GA), and a hybrid algorithm based on simulated annealing. The computational results demonstrate the efficiency of the developed algorithms. We also develop a decision support system for the VRPTWOV that is equipped with a vehicle route rescheduling function for realistic situations based on the GA.
► We model for the VRPTW with outsourcing vehicles and overtime (VRPTWOV).
► We develop a mixed integer programming, a GA, and a hybrid algorithm for the VRPTWOV.
► We develop a decision support system for the VRPTWOV based on the GA.
► The system can be a useful for the manager of the third party logistics companies.
