充填管道磨损风险评估的组合权重与可变模糊耦合模型
An integrated model of combination weights and variable fuzzy on evaluating backfill pipeline wear risk
摘要
Abstract
Based on the complexity and incompatibility of factors of pipeline wear risk, the subjective and objective combination weights and variable fuzzy sets were introduced to evaluate the backfill pipeline wear risk. The 12 main factors, i.e., weighted average particle size of backfill aggregation, shape of backfill aggregation, slurry density, slurry corrosivity, pipeline wear resistance, pipeline inner diameter of drill-hole, pipeline thickness, drill-hole inclined rate, multiple ratio pipeline length to column in backfill, installation quality, the ratio of velocity and critical velocity and degree of pipeline changes, were selected. An integrated model of the wear risk evaluation of backfill pipeline was established by the subjective and objective combination weights and variable fuzzy sets. Taking measured data of supply pipeline of backfill system in five domestic mines for example, the optimum combination weight of factors were determined by AHP and information entropy, then comprehensive risk characteristic value was calculated by variable fuzzy model, and risk grade of backfill pipeline wear was obtained, and finally the accuracy was validated through comparing the results with other evaluation models. The results show that this model results are consistent with those of other models and the actual results. It also provides a new method for wear risk evaluation of backfill pipeline.关键词
