基于灰色模糊算法的机床产品制造系统能效评价方法

针对机床产品制造系统具有能耗主体构成的多样性、复杂性、以及动态变化的随机性的特点，从经济、产品、设备和任务流程4个方面，归纳出了10个评价指标，构建了机床产品制造系统能效评价指标体系.本文提出了一种组合能效评价方法，在确定权重的环节采用粗糙集-AHM组合的方法，充分综合了客观与主观两方面的指标权重值，在其他环节应用了灰色关联法和模糊评价法，克服了能效评价过程中的灰色性和不确定性.最后，通过实例分析和仿真对比验证了该能效评价方法的可行性、稳定性.

Energy Efficiency Evaluation of Machine Tool Manufacturing System Based on Grey Fuzzy Algorithm

For machine tool manufacturing system has the characteristic of diversity, complexity and randomness of dynamic varity in main body of energy consumption structure, ten evaluation indexes are concluded from four aspects including economy, products equipments and task flow, and energy efficiency evaluation index construction of machine tool manufacturing system is structured. In this paper, a combination evaluation method of energy efficiency is proposed. The combination of Rough Sets and AHM is adopted in the step of determining weights, which combines the subjective and objective of weight value. Besides, the gray correlation method and grey fuzzy evaluation are used in other steps, to avoid grey and uncertainty. Lastly, living examples and simulation contrast experiment verify the feasibility and stability of the method.
