摘　　要：将模糊数学和灰色理论结合在一起 ,针对目前复杂大系统的多目标决策问题 ,提出了一个简单实用而且有效的灰模糊求解方法 ,通过隶属函数的一致性使确定型指标和模糊型指标能融合在同一个决策中加以考虑 。Fuzzy Mathematics and Grey theory are combined together in this paper,aim at multiple objective decision of large complex system,a more simplicity utility and virtual Grey- fuzzy solution is given.By the coincidenceofsubjection function,ascertain type indices and blur type indices are combined to consider.At the same time a Grey- fuzzy method to ascertain weightrelation to subjection degree is introduced.
