民航安全信息工作绩效评价指标体系研究

为完善安全信息工作管理制度,提高民航业安全信息工作的质量,将平衡计分卡方法(BSC)进行变型,结合实际工作经验,将平衡计分卡4个层面的逻辑关系由传统的递进关系,变为并列递进关系,构建民航安全信息工作绩效管理指标体系.先采用层次分析法求取主观权重,然后用变精度粗糙集求取客观权重,最后将主、客观权重通过最小相对信息熵原理进行优化,并且采用改进的TOPSIS方法从新的角度对指标体系的信度和效度进行验证.结果表明,一级指标"安全信息的质量"最优权重为0.407,占总权重的40.66%,是评价安全信息工作优良的决定性指标;而其二级指标"安全信息的规范程度"的ρi值最大,反应了该指标信度效度最大,达到0.288,占总权重的11.97%,在安全信息工作绩效管理中最重要.该指标体系可以实际应用于安全信息工作绩效管理过程,有助于提升安全信息工作的管理水平,提高安民航安全信息的质量.

A Study on an Index System of Performance Management for Safety Information in Civil Aviation

In order to modify the regulations of safety management and improve the quality of safety information in civil aviation, the balance scored card (BSC) method is modified to develop an index system of performance management for safety information.The logical relation of four levels in BSC is adjusted from traditional progressive to parallel progressive.To determine the weights of indices, the methods of analytic hierarchy process (AHP) and variable precision rough set (VPRS) are used to obtain subjective and objective weights, respectively.The subjective and objective weights are optimized by principle of minimum relative entropy (PMRE).This new index system is validated by an improved TOPSIS method.The results show that, the quality of safety information is the key factor to evaluate the performance.Its optimal weight is 0.407 and accounts for 40.66% of the total weight.One of the secondary indices, the specification degree of safety information weight, contributes the largest ρi.Its optimal weight is 0.288 and accounts for 11.97% of the total weight, indicating the largest reliability and validity for the performance management system.Hence, the proposed index system can be applied to actual processes of performance management for safety information in order to improving the level of management as well as the quality of safety information in civil aviation.
