Outline of Final Research Achievements

In agricultural production management and agricultural product cost management, it is inevitable to set appropriate standard values for crop yields and other production indicators. However, there are situations where standard values themselves are not set, or even if they are, they are not appropriate. In this study, we chose to consider mode, which have been regarded as "typical" or "normal" values, as standard values. Although mode is usually obtained from histograms, mode in this method is not unique because the anchor position is arbitrarily set. Therefore, "bell-form frequency mode" and "alternate optimum mean" were developed as unique mode, and the standard value setting method was improved.

農業経営管理（Farm Management）

Academic Significance and Societal Importance of the Research Achievements

農業生産管理や農産物原価管理等の農業経営管理においては、労働時間や作物収量等の生産指標の適切な標準値の設定を行う必要があるが、営農の現場で標準値の設定が適切にできていないのが現状である。本研究では、最頻値をもって、標準値とみなす立場を選択した。最頻値は、通例のヒストグラムから求める方法では一意性がない。そこで、一意的な最頻値として「鍾形頻度最頻値」と「代替最適平均」を学術上新規に考案して、実際の農業経営管理の改善に寄与しようとした。
