机务维修人员疲劳风险评价模型及管理系统实现

Fatigue risk evaluation model and system for civil aviation maintenance personnel

为量化评价民航机务维修人员疲劳风险,首先通过调研和德尔菲法构建机务维修人员疲劳影响因素评价指标体系,依据灰色聚类原理,建立民航机务维修人员疲劳风险灰色聚类评价模型;然后从维修单位采集实际数据,结合各指标权重,通过算例验证模型的有效性;最后将模型应用于机务维修人员疲劳风险管理系统的开发中,实现调查问卷的电子化和评价过程的自动化计算。结论表明:用灰色聚类模型可实现机务维修人员疲劳风险的量化评价与分级,系统软件可作为机务维修单位疲劳风险管理的实际工具进一步推广应用。

For the sake of evaluating fatigue risk of civil aviation maintenance personnel in a quantitative way,firstly an evaluation index system of fatigue inducing factors was developed based on Delphi method and a fatigue risk evaluation model for aviation personnel was built based on the gray clustering principles.Then the practical data were collected from a certain maintenance company and a case study was conducted for validating the model.Finally,the model was integrated into the development of a fatigue maintenance management system where the electronic questionnaire processing and the automated calculation process were realized.The findings of this study indicate that this gray clustering model could be used to quantitatively evaluate fatigue risk of maintenance personnel and the system could be used by maintenance organizations as a practical tool for fatigue risk management.
