制造设备关键性能指标的基准设定

Benchmark determination for key performance indicators of manufacturing equipment

详细分析流程行业制造执行系统关键性能指标评估体系,建立了关于制造设备的关键性能指标集合。针对该评估体系的动态分析部分,提出了基于稳态优化理论的制造设备关键性能指标的基准设定方法,最后以二元精馏塔为例分析了其生产率的计算以及基准的确定。

This paper detailed analyses the evaluation architecture of key performance indicators（KPI）for manufacturing execution system（MES）in process industry,and a collection of KPI for manufacturing equipment is established.According to the dynamic analysis part of this evaluation architecture,a method based on steady-state optimization is proposed to determine the benchmark for KPI of manufacturing equipment.Finally,the calculation and benchmark determination for the produced ratio of a distillation column are achieved as an application case.
