A Prioritization Method of Adjusting Parameters for Making Consensus on Combination of Risk-reducing Plans by Mutual Effect Analysis

Abstract

This paper addresses the prioritization problem of parameters for making consensus on the combination of risk-reducing plans. However, the existing method can not prioritize the parameters correctly based on the differences in “preferences”. So, we propose a prioritization method of adjusting parameters by mutual effect analysis. The proposed method defines the change rate of the preference as the mutual effect. Whether the mutual effect works or not is decided by “independent score” with the change rate. The risk-reducing plan which has strong mutual effect is prioritized in descending order of the mutual effect represented as “influence score”. As a result, the proposed method can improve averages of occupancy of parameters to be adjusted in top 5 of the priorities by 30%, and allow the parameter adjustment to be completed in an hour.
