New statistical analysis on the marketing research and efficiency evaluation with fuzzy data

– The purpose of this paper is to use soft computing technique and fuzzy statistical tool to evaluate people's performance on the marketing research and time management.

– Through standardized measurement system, the authors come up with real-value data to satisfy not the current needs but data itself. This is when fuzzy classification stands out and highlights the area of in-between and undefined.

– The proposed metric system helps the authors to assess the distance among trapezoidal fuzzy data. The index of efficiency between observed time and ideal time is also presented.

– With the ranking of fuzzy sample, the authors can examine the decision process by non-parametric testing hypothesis.
