摘要
在云制造模式下,制造服务评价指标的赋权方法直接影响制造服务的评价数值和选择结果。采用G1-法和变精度粗糙集理论两种主、客观赋权法,分别对云制造服务评价指标进行赋权,然后基于最大熵原理的组合系数模型,集成两种赋权评价结果,协同主、客观因素对云制造服务评价的影响。最后通过实例验证了基于最大熵原理集成赋权方法的正确性和可行性。
Under cloud manufacturing mode,the weighting method of manufacturing service evaluation indexes directly affects the evaluation values and selection results.The two subjective and objective weighting methods of G1-method and variable precision rough sets theory are used to weight the evaluation indexes of cloud manufacturing services respectively.The combined coefficient model based on maximum entropy principle integrates two weighting results to coordinate the influence of subjective and objective factors on cloud manufacturing service evaluation.Finally,an example is given to verify the correctness and feasibility of the integrated weighting method base on maximum entropy principle.
