Initialization for optimization of real world vehicle routing problem
 Volf, Robin ; Klhůfek, Jan (referee) ; Sedlák, David (advisor)
The goal of this work is to optimize the initialization phase in solving the rich vehicle routing problem on a specific dataset which comes from a czech logistics company's data. This dataset has characteristics of VRPTW, VRPSPD and HFVRP. A modified cheapest insertion heuristic was chosen for the solution. Cost calculation consists of six partial costs which reflect individual constraints. Proposed heuristic is able to solve the instances in a matter of few seconds. Construction heuristic which generates valid solutions in short time enables more effective optimization in latter parts of solution.
