基于层次分析法的铁路信息系统软件产品易用性的研究

Usability of railway information system software based on AHP

本文将国标通用的易用性度量模型与AHP方法相结合,利用众多决定产品易用的子特性构造判断矩阵并计算权重,根据权重值得出各子特性重要程度的先后次序,从而提出评价铁路信息系统软件产品易用性的方法。以某机房动力环境集中监控系统为例,采用基于AHP的铁路软件产品易用性评价方法,通过YAAHP软件完成该系统易用性评价的整个流程。

Nowadays, software solutions of railway information system were paid attention mainly with comprehensive function, process control, and advanced techniques, ignoring the usability. Regarding to the markets feedback, it was obviously essential to satisfy user experience by client oriented products designed more precisely and accurately. Herein the article proposed a method to evaluate the usability of railway information system software by the combination of the international standard usability measurement model and AHP. The sub-feature of determining the usability of solutions was used to construct the judgment matrix, and calculate its weight, according to the weight value, the precedence of important degree was made. Taking an existing Power Supply and Environment Centralized Monitory System as an example, based on the proposed method, the usability was evaluated by YAAHP.
