Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, on-demand mobility services such as food delivery and ride-sharing have rapidly expanded, significantly impacting people's daily lives. In this paper, online optimization of the pickup and delivery problem is studied. In particular, we focus on incorporating an accident recovery forecast. First, the target area is modeled by a set of graphs. Next, constraints and cost functions are introduced. Then, the pickup and delivery problem is rewritten as a mixed integer linear programming problem. Finally, we provide numerical examples illustrating the computational results under accident scenarios with the incorporation of an accident recovery forecast.
