面向多主体、多任务的维修保障信息建模技术

Maintenance Information Modeling Technology Facing Multiagent and Multitasking

针对装备使用阶段维修保障信息采集需求不确定性大、变动性强等问题,研究了面向多主体、多任务的维修保障信息建模技术.从维修保障数据、维修保障信息和维修保障知识等三个层面研究了维修保障信息应用的基本模式;提出了基于模型树方法的维修保障信息采集需求确定技术,并分析了维修保障信息的可采集特性;针对维修保障信息的多主体和多任务特性,提出了基于事件驱动的维修保障信息建模方法;最后设计开发了维修保障数据仓库管理系统.研究结果表明,提出的信息建模方法具有高度的开放性和扩展性,能够应对维修保障信息采集需求不断调整变化的现实.

In order to resolve the uncertainty and variability of equipment maintenance information collecting requirement in the process of equipment employing, maintenance information modeling technology facing multiagent and multitasking is studied. The basic applying mode of maintenance information is studied from the sides of maintenance data, maintenance information and maintenance knowledge. Maintenance information collecting requirement ascertaining technology based on model tree is presented, as well as the the characteristic of information being gained. Aiming at the characteristic of multiagent and multitasking, maintenance information modeling method is presented based on event driving mechanism. At last the maintenance data warehouse system is designed. The research result shows that the maintenance information modeling technology being provided with favourable opening and expanding can deal with the fact of variational maintenance information collecting requirement.
