根据带式输送机质量评价指标的多元性特点,而且定量与定性指标并存,应用可拓学理论,建立了带式输送机的质量评价物元模型。利用可拓集合理论中的关联函数计算出关联度,应用层次分析法确定评价指标权重,得出待评价机型的质量等级。以某种带式输送机为例进行了应用研究,结果表明该方法具有一定的实用性,评价结果较合理。
According to the characteristics of the quality of the belt conveyor, the quantitative and qualitative indexes coexist. Based on the theory of extenics, the matter-element model of belt conveyor quality evaluation is established. Correlation degree is calculated by using the correlation function in extension set theory. The analytic hierarchy process is used to determine the weight of evaluation index and the quality grade of the model to be evaluated is obtained. An example of a belt conveyor has been applied research, the results show that the method has some practicality, the evaluation results are more reasonable.
