Abstract (in Japanese) (See Japanese page) 
(in English) In data analysis, conditions that are effective for KPI are extracted and multiple actions are planned. However, when executing multiple action plans at the same time, because of the intersection between their targets, it is not the most effective for KPI to execute the combination of action plans which have the best score. For the search method for best combination of multiple action plans, all combinations of action plans must be considered in the worst case, and calculation cost was a problem. In this research, we propose a method to reduce the calculation cost by efficient search method using novel defined upward compatibility among action plans. We applied the proposed method to the data of academic achievement and evaluate the calculation cost. As a result, we reduced calculation cost by 60 percent.
