Abstract:This paper presents a variant of the vehicle routing problem (VRP) that combines several constraints. This variant addresses the pickup and delivery problem (PDP), the use of multiple vehicles (m), the multi-depots (MD) and the time constraint (TW): m-MDPDPTW. In the m-MDPDPTW, one should build a route made up of several pairs (customer / supplier), which starts and ends at the same depot and respects the precedence and capacity constraints. For solving this problem, two approaches based on particle swarms are… Show more
