多风机多级机站通风系统优化的模糊群体决策法

Study on optimization of mine ventilation system of multi-fan and multi-stage based on fuzzy population decision

矿井通风系统是一个复杂的非线性系统,具有随机性、模糊性和不确定性特征。为了实现矿井通风的系统安全,对系统的安全性进行了定性、定量的预测分析和安全评价。按目标分层,用分层模糊优选理论对矿井通风系统设计方案进行优选,分层时允许评价因素重叠,从而便于确定目标与评价因素的权重。对矿井通风系统建立了多个设计方案的评判指标体系,并应用模糊群体决策确定矿井通风系统方案评判指标的权值,研究成果已应用于中条山有色金属公司胡家峪铜矿通风系统优化研究中,获得了满意的结果。

Mine ventilation system is the complex nonlinear system, which is random, fuzzy and uncertain in characteristics. In order to realize system safety of mine ventilation, a qualitative and quantitative pre-measurement analysis and safety assessment is conducted for the system safety. The stages are divided according to the objectives. The factors of evaluation are allowed to overlap so that the weights of the objectives and factors of evaluation can be determined easily. Through the theoretical analysis and case study, the model has been proved to be more universal and efficient than the fuzzy comprehensive decision making model. This method is applied to the optimization of reconstruction design of ventilation system in a copper mine.
