| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In a bike sharing system (BSS) , we proposed a multiple-Vehicle Bike Sharing System Routing Problem (mBSSRP) to determine short tours to adjust bicycles using vehicles in short time. However, it is difficult to construct feasible solutions for some instances due to strict constraints of mBSSRP. Therefore, we proposed a multiple-Vehicle Bike Sharing System Routing Problem with Soft Constraints (mBSSRP-S) that removes some constraints from mBSSRP and adds those violations to objective function of mBSSRP as penalties. Furthermore, we proposed a dynamic weight adjustment method to efficiently explore both feasible and infeasible solution space of mBSSRP by solving mBSSRP-S. Numerical experiments have shown that we obtained good solutions for instances with about 50 ports. However, the number of ports in real BSSs in more than hundreds. Thus, in this study, we investigate the performance for large-scale instances. As results of numerical experiments, we confirm that good solutions of mBSSRP are obtained for the large-scale instances. | |
