摘要
服务通告是为改进航空产品可靠性和安全性而向运营商发出的一种服务性文件,其中的人工工时关系到运行成本和实施决策,然而我国服务通告人工工时依靠经验来确定,随意性大。针对该问题,提出了一种基于网络图的工时计算法,开发了相应的计算软件。首先,根据各工序关系与时长构建一种有向网络图;然后,计算网络图的时间参数获得总工时、最短工时和关键路径。最后,提出采用三个时长典型区间值进行并行处理,并在开发的计算软件上通过人机交互实现工时计算过程。
Service Bulletin is a service document issued to operators to improve the reliability and safety of aviation products.The labor hours are related to operating costs and implementation decisions.However,the labor hours for service bulletin in China are determined by experience,which are highly random.Specific to this problem,a method of calculating labor hours based on network diagramis proposed,and the corresponding calculation software is developed in this paper.First,a directed network diagram is built according to the relationship and duration of each process;then,several time parameters in the network diagram are defined in order to calculate the total labor hours,shortest labor hours and critical working paths;Finally,it is proposed to use three typical interval values for parallel calculation.The whole process is realized by human-computer interaction on the developed calculation software.
