基于犹豫模糊集的制造过程多指标定量综合评价法

制造过程的稳定性是企业保障产品质量的基础,针对以往过程管理中缺乏系统的、全面的定量分析工具的问题,建立了面向制造过程的多指标定量评价体系,对制造过程的各影响因素进行具体分析定点评价,并基于犹豫模糊理论和多准则决策方法给出了过程因素期望指数和制造过程期望指数的计算步骤,以评价等级表的方式将制造过程所处的生产状态进行量化表达.实例分析表明,该方法能帮助管理者直观有效地评价制造过程状态,为企业在数字化生产建设方面提供更多维度的管理数据.

Comprehensive Evaluation Method for Quantitative Multi-indexes of Manufacturing Process Based on Hesitant Fuzzy Sets

Stability of manufacturing process is the basic for the company to guarantee the produce quality. In view of the lack of systematic and comprehensive quantitative analysis tools in the past process management, a multi-index quantitative evaluation system for manufacturing process is established. The influence factors on manufacturing process are analyzed and evaluated, and the calculation steps of process factor expectation index and manufacturing process expectation index are given based on the hesitant fuzzy theory and multi criteria decision making method. The production state of manufacturing process is expressed quantitatively by the rating scale. Case analysis shows that the method can help managers to evaluate the manufacturing process status intuitively and effectively, and provide more dimensional management data for enterprises in digital production construction.
