Establishment and Application of a Grey Quality Gain–Loss Function Model

Based on Grey System Theory and the inverted normal quality gain–loss function, grey function model is put forward. According to constant compensation hyperbolic tangent compensation, with nominal-type characteristics, larger-the-better characteristics smaller-the-better built. A multivariate multiple sub indexes concept of cost are proposed. Case analysis applied control dam concrete construction, which verifies applicability provides an important reference for research new theory construction control.
