企业信息化环境下人-信息系统交互效率

Influence Mechanism of Matching on Human-information System Interactive Efficiency Within Enterprise Computerization Environment

针对制造业人-信息系统(H-IS)交互效率不高的问题,提出从任务-人-信息系统匹配的角度来优化交互效率,构建了人、任务、信息系统和交互环境匹配优度的概念模型。分析了任务与人、任务与信息系统、人与信息系统匹配对交互效率的影响机理,分析结果表明:任务与人的匹配、人与信息系统的匹配通过认知负荷、心理负荷影响人的认知效率和信息加工效率,进而影响人的自我效能感、焦虑程度和操作错误数;任务与信息系统的匹配通过员工的焦虑和信息系统功能的合理性要求影响人的情绪,进而影响人的觉醒水平和认知效率,最终影响人-信息系统交互效率。

Aiming at the fact that manufacturing human-information system（H-IS） interactive efficiency is lower, optimizing interactive efficiency is proposed from the view point of matching among task, human and IS. Matching notional model is built, the action mechanism is analyzed. Mechanisms analysis results show that the matching between human and tasks, human and IS affect cognitive efficiency and information processing efficiency by cognitive load and psychological load, further affect self-efficiency, anxiety and the number of operational errors of human. The matching between tasks and IS affects emotion by anxiety and the demand of IS rationality, and affects awakening level and cognitive efficiency, and ultimately affects H-IS interactive efficiency.
