摘要
为增强企业性能建模中性能指标之间关系的表达能力,改进了基于因果关系的性能建模方法,提出了一种基于条件概率的指标关系改进方法。通过在性能指标关系的测度与性能指标的状态值之间建立基于条件概率关系的联系,研究了性能指标关系的动态变化特性。为了进一步增强该方法在表达性能指标关系方面的能力,扩展了所提出的基本模型。指出了这种性能建模方法在应用中需要解决的关键问题和可能的解决途径。最后,通过仿真举例,说明了该方法的有效性。
To improve the representation capability for index relationships in enterprise performance modeling, the performance modeling method based on casual relationship was improved and an index improvement method based on conditioned probability was proposed. To study the dynamic characteristics of the Performance Indicator （PI） relationship, the association between the measurement of PI relationship and the status of PI was set up. And then, the proposed basic model was expended in several directions to further improve the representation capability. Key problems in the application of the method were pointed out,and possible solutions to these problems were also provided. A simulation example was finally provided to explain its effectiveness.
