Abstract

The paper presents the variant of vehicle routing problem that considers the optimal integration of forward flow of materials from manufacturer to customers with a backward flow of materials from customers to specialised warehouses or recycling sites. The problem is called vehicle routing problem with simultaneous pickup and delivery (VRPSPD). In VRPSPD, a customer requires a given shipment to be delivered as well as a given load to be picked up simultaneously. Complete service (i.e., delivery and pickup) to the customer is provided by a vehicle in a single visit and thus the load of a vehicle fluctuates over the route. Given that the load fluctuates over the route, an important issue of VRPSPD is checking the feasibility of a route during local search. In this paper, we present the cumulative net-pickup approach for checking the feasibility of a vehicle route while performing neighbourhood search in local search schemes.
