基于PCA-LINMAP-FCE的通信系统维修性评价方法

Method of maintainability evaluation based on PCA-LINMAP-FCE for communication systems

为提高通信系统维修性评价的实用性和可操作性,提出了一种基于PCA-LINMAP-FCE的维修性评价方法.在构建简化的维修性评价指标体系的基础上,将PCA-LINMAP与模糊综合评判(FCE)方法相结合,从定量和定性的角度对维修性进行评价.实例仿真分析表明,该方法可操作性强,且有效地降低了评价的主观随意性,使维修设计和作业人员全面掌控通信系统装备维修性的影响因素,能够为科学制定设计方案和维修实施决策方案提供决策信息.

In order to enhance the practical and operational performance, a method based on PCA-LINMAP-FCE for maintainability evaluation is proposed. Combining PCA-LINMAP with fuzzy comprehensive evaluation, the pro- vided approach evaluates the maintainability quantitatively and qualitatively on the basis of a simplified evaluation index system. Experimental results show that this high operational method reduces the arbitrary of subjective evalua- tion effectively. It is useful for maintenance personnel and designer to get acquainted with influencing factors of ma- intainability, and supply decision-making information for scientific design and implementation of maintaining scheme.
