Creation of a Schedule Considering the Possibility of Rainout in a Professional Baseball Game – In the Case of Central League Schedule in 2017 –

Abstract

In this research, we aim to create a schedule in professional baseball that makes the difference of remaining game number among teams as small as possible. We consider not only making of deterministic schedule, but also a schedule that takes into account uncertainty such as cancellation due to rain. First, a schedule is generated by integer programming. By considering the rainout, we try to minimize the difference in the number of remaining games among the teams. In this research, we reduced the number of remaining games compared with the actual schedule, the difference between the maximum expected value and the minimum value of each team could also be suppressed. As a result, it is possible to reduce difference in the number of remaining games among the teams.
