改进德尔菲法在驾驶舱显示系统工效学评价指标筛选中的应用研究

目的 筛选出驾驶舱显示系统工效学评价指标。方法 首先，对国内外相关资料进行了广泛收集，在对资料进行系统分析和综合的基础上，初步形成了驾驶舱显示系统工效学评价指标体系。然后，针对初步确定的指标体系，采用改进德尔菲法，聘请了飞过多种型号飞机的23名现役有经验飞行员作为专家咨询人员进行了两轮咨询，并对咨询结果进行了统计处理。结果 通过两轮专家咨询，筛选出了对驾驶舱显示系统工效学评价影响大的指标。结论 改进德尔菲法作为一种充分发挥专家智慧、知识和经验的方法，具有一定的科学性和可操作性。

Study on Modified Delphi Method as Used for Index Filtration in Ergonomic Evaluation of Cockpit Display

Objective To build an index system for ergonomic evaluation of cockpit display.Method The modified Delphi method was proposed to build the index system.Firstly,on the basis of systematic,in-depth analysis and integration of the related information such as military standards,norms and technical productions both domestic and abroad,an index system for cockpit display ergonomic evaluation was primarily built.Then,23 fighter pilots were referred twice as the specialized consultants upon preliminary index system with the modified Delphi method.Finally,the comements of the specialized consultants were statistically analyzed.Result Based on the two times of information from the specialized consultants,the indexes that could cause more impact on pilots' efficiency were selected.Conclusion Modified Delphi method characterized with referring and synthesizing experimental results from experts is scientific and operatable.
