Method of Evaluating Product Concepts Based on Improved Rough Set Grey Analysis

Abstract

Abstract:

Based on the improved rough set gray analysis,a new method was proposed to valuate the quality of the products with different indexes and different coefficients,combining the strengths of the fuzzy to deal with fuzzy problem and grey correlation analysis to make decision of multiple attributes.An example shows that this method can be used for evaluation and choice of multiple products with standard operation and can save assessment time.

Key words: product concept evaluation, user satisfaction, rough set grey analysis, difference index

摘要：

基于改进后的粗糙集灰色分析,提出了一种用差异指数和差分系数来评估产品品质的方法,该方法结合了粗糙集处理模糊问题的长处与灰色关联分析解决多重属性决策问题的优势。经实例验证，该方法便于对产品多个方案进行评估和优选，同时操作规范、节约评估时间。
