"Mathematical evaluation methods and application to business"
Abstract: In order to allocate suitable persons to positions, we need to evaluate candidates and choose favorable ones. Note that an evaluation method should assure fairness and candidates are evaluated from many aspects. Usually data of evaluation are collected from voting by experts. Experts vote candidates with their favorable ranking. Based on these voting data, we evaluate candidates by ranking them. Or we make consensus among experts using some distance function between final ranking of candidates and favorable ranking of candidates by experts. First we briefly review standard evaluation methods, i.e., DEA, DEA based ranking method, AHP, Conjoint analysis and propose some extended method such as class-wise conjoint method. Using these method, we show some pplications to business. Next we review consensus making methods such as Cook and Kress relative distance method and its extension including scenario analysis and linguistic data analysis. Again using these methods we show some applications of consensus making methods including allocation of players to positions in some sports. Finally we discuss the further research problem such as how to break ties, fractional voting systems, how to assure fairness etc.
