چکیده

Pickup and delivery problem with time windows (PDP-TW) is a challenging scheduling problem for which each delivery is coupled with a pickup request. Metaheuristic search techniques like the tabu search have been used to solve PDP-TW. In this paper, we investigated a min-conflicts based micro-genetic algorithm combining some interesting construction heuristic, namely the Align-Fold or Boomerang, and repair heuristics including a new Swap operator and a modified billiard operator to effectively solve PDD-TW. Our results compared favorably against those of a tabuembedded metaheuristic search on a set of modified Solomon’s test cases. More importantly, our proposed heuristics can easily be integrated into many search schemes for solving other complex scheduling problems.

An Improved Particle Swarm Optimization for a Class of Capacitated Vehicle Routing Problems

Vehicle Routing Problem (VRP) is addressed to a class of problems for determining a set of vehicle routes, in which each vehicle departs from a given depot, serves a given set of customers, and returns back to the same depot. On the other hand, simultaneous delivery and pickup problems have drawn much attention in the past few years due to its high usage in real world cases. This study, therefo...

Improving the Initialization and Repair Heuristics to Effectively Solve the Pickup and Delivery Problems with Time Windows

Pickup and delivery problems with time windows (PDPTW) are challenging yet realistic scheduling problems in which each delivery vehicle is assigned to handle different pairs of pickup-anddelivery requests. Our previous work successfully adapted the push forward insertion heuristic (PFIH) for initialization, and proposed a new swap operator to effectively solve PDP-TWs. In this paper, we improve...
