| Outline of Final Research Achievements |
It is now possible to formally describe a production system with uncertainty under static conditions. In other words, if we focus on the occurrence time of an event and consider that the event can be scheduled from the occurrence time, we can think of the problem as an allocation problem for the schedule. These ideas can now be formally described.
We were also able to propose a new solution method for production systems with uncertainties. This was also realized by using a model that pays attention to the occurrence of uncertain events and makes a decision on whether or not scheduling should be performed at that time.

不確実性を含む生産システムの形式化は，その学術的意義は高い．形式化することで静的ではあるが，不確定事象を含む生産システムの最適解と最適値を求めることができる．最適解からどうすればよかったのかを知ることができ，新しい解法につながる可能性がある．
またこれまでの解法に対しても，解を比べることでどうすれば改善することができるのかを指し示すことができる．さらには最適値より，それらの解法を評価することが可能となる．以上のことから本研究は高い学術的な価値があるといえる．
