摘　　要：为了更精确合理地对新桥硫铁矿排水方案进行优选,对利用突变理论的方法进行优化,建立突变理论和熵权法相结合的改进模型。从经济和工程量方面出发,综合考虑了影响排水方案优选的3个层次的12个指标,统计样本数据。运用熵权法分层确定同一上层变量下各指标的客观权重,导入突变理论中,建立综合评价结构模型,消除了主观因素的影响。同时运用突变理论和EM-TOPSIS进行方案优选,通过对比3种方法的优选结果,证明了改进突变理论的可靠性与合理性。This paper is aimed at developing a drainage scheme of Xinqiao pyrite mine in an optimistic way. For this purpose,we have established an optimization model which joins the catastrophe theory and the entropy weight method into our scheme model.Among the numerous factors that influencing the drainage scheme optimization,we prefer to believe that the principles of practicing economy and engineering should be the most important ones among all the others. Keeping this thinking line,we have chosen12 indexes in 3 levels and then worked out all the sampling data necessary in one stroke. Starting from the data in calculation,we have first of all adopted the entropy weight method to obtain the objective balanced system of the indexes which should be put under the same sphere of the superior and first-rank indispensable variables. Thus,we have imported all the objective weights into our catastrophe theory model. And,then,in accordance with the size of the weights,we have decided the primary and secondary control variables and ranked them in a well-arranged manner. A hierarchical pondering helps us to chalk out the final mutation function system. And,then,we have worked out the most likely to be the idealistic drainage scheme on the basis of the function value system. At the same time,we began to resort to the catastrophe theory and the method named EM- TOPSIS to process the basic data and pick up the optimal projects. Comparing the results achieved by using the three methods,it has become clear that the optimistic results of the improved catastrophe theory consideration are different from all kinds of the catastrophe theories but the same as EM- TOPSIS＇. Judging from what we have made as the forecast likeliness,the following conclusions can be drawn：First of all,the catastrophe theory ＇s calculation results may change when the entropy weight method is introduced to. The next version in importance will tell us that the subjective factors may lead to the different outcomes that we can get from the catastrophe theory＇s
