Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Originality/value

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