受粗糙集理论中知识约简的启发,在模糊多属性决策理论中提出属性约简的概念,构建属性约简方法,寻求属性集合中所有最简单的保序属性约简子集以及属性约简核。用属性约简子集代替原有的属性集合,通常可以显著简化模糊多属性决策问题。还将此属性约简方法应用到生产线工位绩效评估中,表明此属性约简算法的实用性。
Enlightened by the knowledge reduction techniques in rought sets theory,attribute reduction conceptions and method are introduced into the fuzzy MADM problems.The purpose of this method is to search for all the simplest order-preserving attribute reduction subset and order-preserving core of the original problem.Then one of the attribute reduction subset could be used to substitute the original fuzzy MADM attribute set so as to simplify the decision making process.Furthermore,we apply this attribute reduction method in work-station performance evaluations to verify its validity and practicability.
