【摘要】：针对离散制造系统具有能耗主体构成的动态变化随机性、多样性、以及复杂性的特点,从产品、设备、经济和任务流程4个方面,归纳出9个评价指标,建成了离散制造系统能耗评价指标体系。该方法基于改进熵值法的能效评价方法,针对熵值法在赋权时当某个指标的离散程度太大时,该指标会出现权重过大这一问题,借层次分析法的赋权思路,将主客评价结合起来,更好的对离散制造系统进行科学的评价。通过实例分析与仿真来对比验证该能效方法的稳定性、可行性。
[Abstract]:In view of the randomness, diversity and complexity of the dynamic change of discrete manufacturing system, nine evaluation indexes are concluded from four aspects: product, equipment, economy and task flow.The energy consumption evaluation index system of discrete manufacturing system is established.This method is based on the energy efficiency evaluation method based on the improved entropy method. When the discrete degree of an index is too large, the weight of the index will be too large when the entropy value method is weighted.Combining the subjective and objective evaluation, the discrete manufacturing system is better evaluated scientifically.The stability and feasibility of the energy efficiency method are verified by example analysis and simulation.
