摘要:
This paper addresses a vehicle routing problem which considers customers to require simultaneous pickup and delivery service (VRPSPD). The VRPSPD problem is an NP-hard combinatorial optimization problem; therefore exact methods are incapable of solving large scale VRPSPD instances. A tabuembedded simulated annealing metaheuristic (TSSA) that utilizes four different neighborhood structures is presented to deal with this problem. 18 test problems with 100-400 customers from Montane and Galvao's benchmark are used to test the performance of the TSSA algorithm. Computational results demonstrate that TSSA could produce high quality solutions. ©, 2015, Journal of Computational Information Systems. All right reserved.
