部分权重信息下地下工程施工安全模糊决策研究

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

结合直觉模糊集理论提出了处理地下工程施工安全问题的方法,其用直觉模糊集描述不同防护措施对于地下工程各种不安全因素的满足和不满足程度.在属性权重部分已知的情况下,通过权重可能属性分析,建立单目标优化模型,求出目标模型的权重向量,并由此求出各方案的综合属性.根据各方案综合属性建立可能度矩阵;通过对可能度矩阵排序分析,得到各方案的排序向量;根据排序向量分量的大小对直觉模糊集进行排序,求出最佳防护方案.该方法能更好体现决策者的意愿和要求及被评价对象的真实水平或好坏程度,可避免人为因素的影响,为决策者提供有力的理论支持.

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.
