Abstract
This article addresses a logistics districting problem for a company whose operations consist of the pickup and delivery of packages within a region. The service region is to be divided into districts, each served by a single vehicle that departs from a central depot. The district design aims to optimize two criteria: compact district shape and balance of workload content among districts. We present a mathematical formulation of the problem as well as a multi-start heuristic procedure to solve the problem. The procedure combines some elements of metaheuristics such as Tabu Search and GRASP. Experimental results in comparison with CPLEX solutions are presented. ICIC International
