Research on fuzzy decision-making for understructure work construction safety as partial weight information known.

Combining intuitionistic fuzzy sets, a new method for solving understructure work safety problems is presented. The proposed method describes the degrees of satisfiability and non-satisfiability of each understructure work construction protective measure to any unsafe factors by intuitionistic fuzzy sets. As attribute weight part known, through possible attribute analysis of weight, the single-objective optimization model is established, and the weight vector of the objective model is found, then the comprehensive attributes of various programs are obtained. According to various programs' comprehensive attributes, the possibility matrix is established. Through the sorting analysis of possibility matrix, the ordering vectors of various programs are obtained. According to the size of ordering vector component to the intuitionistic fuzzy sets, the best protection plan is got. This method can well manifest policy-maker's wish and request, and the appraised object's real level or quality. It can also avoid the impact of human factors and provide the powerful theory support for the policy-maker. [ABSTRACT FROM AUTHOR]
