On the Distance Constrained Vehicle Routing Problem

, et

We analyze the vehicle routing problem with constraints on the total distance traveled by each vehicle. Two objective functions are considered: minimize the total distance traveled by vehicles and minimize the number of vehicles used. We demonstrate a close relationship between the optimal solutions for the two objective functions and perform worst-case analysis for a class of heuristics. We present a heuristic that provides a good worst-case result when the customers are relatively close to the depot.
