アルカリ乾電池による機能性評価の検討

抄録

Experiments in the evaluation of AA alkaline dry cells were performed to study functional evaluation, Experiments to evaluate functionality in five categories for different purposes were studied, the functionality being stability with respect to ambient temperature. The S/N ratio was used to compare the functionality of alkaline dry cells made by eleven manufacturers. In the evaluation methodology proposed in this study, product function was evaluated as well as functionality, and total cost was also considered. The results showed different S/N trends for each evaluation. The study demonstrated the importance of clarifying the definition of functionality and employing noise factors based on usage conditions, and the necessity of evaluating variability under those conditions. The above showed that it is possible to select suitable products by considering evaluations of functionality and function, total cost, selection problems, etc. in combination with the purpose of the products.
