基于贝叶斯网络的计量服务品质评估

Measurement Service Quality Evaluation Based on Bayesian Network

本文在调研南京市溧水区多家企业的基础上,提出了基于贝叶斯网络的计量服务品质评估。首先建立计量品质评估体系,然后将建立好的评估体系转换成贝叶斯拓扑模型,利用得到的数据计算出先验概率并且确定条件概率,最后刷新贝叶斯网络得到最终的概率评估值。本文的目的在于定量的得到服务评估值,对于提高以后的计量服务策略的制定提供了科学的依据。

This paper proposed a measurement service quality assessment based on bayesian network for investigation of many enterprises in Lishui District,Nanjing.Firstly,we established the measurement quality evaluation system,then mapped the established evaluation system into a bayesian topology model,the obtained data were used to calculate the a priori probability and determine the conditional probability,and finally refresh the Bayesian network to obtain the final probability.The purpose of this paper was to quantitatively obtain the service evaluation value,which provides a scientific basis for improving the future measurement service strategy.
