4. 2. Probabilistic and Experimental Analysis of Heuristic Algorithms for the Multiple-Depot Vehicle-Routing Problem

   Author : Libertad Tansini; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; probabilistic analysis; Multi-Depot Vehicle-Routing problem; heuristics; Time-Windows;

   Abstract : The aim of this thesis is to analyze different heuristic algorithms for solving the Multi-Depot Vehicle-Routing problem (MDVRP) with k depots and n points to be serviced (customers).
