基于信息距离的仓库管理系统易用性测度研究

系统易用性是影响系统军事效益的重要因素,是系统设计时要考虑的一项重要的指标。分析了易用性、功能性以及用户界面关系,采用信息状态转移距离即信息距离理论,研究系统等概率选择和信息状态串联结构时,单路径单目标和单路径多目标组合的易用性信息距离直接测度方法。以车辆器材仓库管理系统的实例,测算系统主路径信息距离和系统平均信息距离等参数,并给出系统易用性评估结论,以供参考。

Study on Ease-of-use Measurement of Warehouse Management Systems Based on Information Distance

In this paper,we analyzed the relationship between ease-of-use,functionality and user interface and,using the information distance theory,studied the method of direct measurement of the ease-of-use information distance when there exists equal probability of selection and serial-connection information status in the system.Then with regard to an empirical example of a vehicle equipment warehouse management system,we measured the information distance of the main route and the average information distance of the system and commented on the ease-of-use of the system.
