| Abstract(in English) | To restore the number of bicycle in each port of the bike sharing system, we have formulated a multi- ple-Vehicle Bike Sharing System Routing Problem (mBSSRP), and proposed a heuristic method. In the mBSSRP, all vehicles must satisfy a time limit constraint and a capacity constraint. In numerical simulation, for some instances, the proposed method cannot find a good solution. One of the reasons is that a current solution of the proposed method in a searching process can not move to a new solution because feasible neighborhood solutions cannot be obtained. Therefore, to find a good solution of the mBSSRP, in this paper, we propose a method that can move to an infeasible neighborhood solution. Specifically, an over time from the time limit and an excess amount from the capacity of vehicle are added to the objective function of the mBSSRP as a penalty. As a result of numerical experiments, we confirmed that we can find better solutions of the mBSSRP by searching for the infeasible solutions. |
