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。
For the characteristic of dynamic change randomness, variety, complexity and diversity in discrete manufacturing system, nine evaluation indexes were concluded from four aspects including product, equipment, economy and task flow, and energy efficiency evaluation index construction of discrete manufacturing system was structured. An improved entropy method was proposed. As the discrete degree of an index was too large when the entropy method was used to assign weight, the weight of the index would be very large. The idea of Analytic Hierarchy Model was used to improve the entropy method. So the improved entropy method could evaluate the discrete manufacturing system more scientifically. Living examples verify the feasibility and stability of this method.
