基于多目标决策的竖井施工方案优选

Optimization of Vertical Shaft Construction Plan based on Multi-objective Decision-making

竖井施工方案的选择涉及施工效率、经济性、安全性和环保性等多个关键维度。为实现这些目标的综合优化,本文首先构建了包括施工速度、单位掘进成本、施工安全性等在内的多目标优选指标体系。随后,收集各施工方案在效率、经济、安全、环保方面的指标数据作为分析样本,并运用优属度公式对数据进行归一化处理。在此基础上,提取理想最优与最劣方案的优属度向量。进一步,采用层次分析法为各项指标分配权重,并据此计算各竖井施工方案的权距优距离和权距劣距离。以最小化权距优、劣距离平方和为目标,求解出各方案的最优隶属度值。通过对比各方案的隶属度值,可确定综合最优的竖井施工方案。实践验证表明,该方法能有效指导矿山竖井施工方案的优选。

The selection of shaft construction schemes encompasses multiple aspects:efficiency,economics,safety,and environmental protection.This paper constructs a multi-objective optimization framework,including indicators like construction speed,unit excavation cost,and safety.Data from various schemes are normalized using the optimal membership formula.The Analytic Hierarchy Process assigns weights to these indicators,enabling the calculation of optimal and inferior distances for each scheme.The optimal scheme is identified by minimizing the sum of squared distances,guiding efficient and sustainable mine shaft construction.
