基于突变理论的开拓方式优选

 鉴于常规多指标决策法在处理开拓方案优选问题时存在不足,建立了基于突变理论的开拓方案优选系统。以新桥矿露天转地下开拓方案为例建立评价模型;综合考虑决策开拓方案的影响指标,如经济、技术、地质、通风与环保条件等;对各评价指标依重要性进行整合处理,构建层状评价系统;应用归一公式对评价系统进行递归运算,计算各方案最终突变隶属函数值,得到3个方案的评价值分别为0.960、0.976和0.953,从而确定方案Ⅱ最优。

Optimization of Development System Based on Catastrophe Optimization Theory

Due to the fact that the conventional multiple attribute decision making methods used to solve the optimization of development system have many drawbacks, an optimization model of the development system is established in this paper based on the catastrophe optimization theory. Taking the development system of the Xinqiao Iron Mine from open-pit to underground as an example, a synthetic assessment model is established. During the evaluation process, many factors of the development system are taken into account, such as the economic and technical factors, the geological conditions, the ventilation and environment protection conditions. All evaluations are sorted by their importance as the first step and then a layered array of the evaluations is established. After that, the recursive calculation is made separately based on the catastrophe optimization theory. Then, the total function values for every method are obtained. The final function values in Xinqiao Iron Mine are 0.960, 0.976, 0.953 and the second model is shown to be the best.
