最佳化報廢機車回收場區位途程模式之研究

In practice, when deciding the location of recycling fields, waste motorcycle recycling companies mostly take account of the rent cost of a site, but the transportation cost has been ignored. Moreover, the vehicle routes for transporting waste motorcycles are planned by decision makers' experiences, without a perspective of systematic optimization. Therefore, in this study the time-space network technique and the mathematical programming method are employed to build a location routing model for waste motorcycle recycling with the goal of minimizing the total operating cost subject to related constraints. To efficiently solve realistically large problems occurring, a heuristic algorithm is also developed. Finally, numerical tests using real data from a Taiwan municipality are performed. The results show that the proposed model and the solution algorithm are good and could be useful references in practice.
