摘要
为了能够选择最优的工艺方案,提高企业效益,提出基于层次分析-灰色关联分析法的机械加工工艺方案评价方法。采用层次分析法(Analytic Hierarchy Process,AHP)对影响加工工艺方案质量的众多因素进行分析,构造科学的、层次化的加工工艺评价体系。运用极值化数据处理方法对各个指标评价值进行无量纲处理,然后通过关联系数和组合权重计算关联度,最终依据方案关联度大小确定工艺方案的优劣。以电磁铁组件为例验证了该评价模型的可行性和实用性。
In order to select the best technological scheme and improve the enterprise benefit,a method of evaluating the machining process scheme based on the Analytic Hierarchy Process( AHP) and grey relational analysis is put forward. The AHP analyzes the factors that influence the quality of processing scheme,and constructs a scientific and hierarchical evaluation system of machining process. The evaluation of extreme data processing method of each index value of dimensionless treatment,then the correlation degree calculated by correlation coefficient and the combination weights,finally according to the scheme the correlation degree determine the process schemes. Taking an electromagnetic component as an example,the feasibility and practicability of the evaluation model are verified.
