摘要: 现有的建模技术在描述维修过程及其相关信息资源等方面存在很大不足,同时缺乏将抽象的维修任务描述与底层维修活动仿真相结合的研究,针对此问题提出并建立了维修任务仿真管理模型 MTN(Maintenance Task Net).构建MTN模型框架并建立基本功能模块,同时阐述了MTN建模的3个要素:状态、活动和条件.基于状态描述各种维修资源,基于活动定义维修动作行为,基于条件建立资源与活动间约束关系.进一步阐述MTN驱动虚拟场景进行维修仿真,同时控制管理整个维修仿真过程.最后给出了应用实例,该模型对实际工程中维修工作分析评价的开展具有一定的实用价值.

Abstract: It is insufficient to describe maintenance process and relevant resources with existing modeling technique, and existing methods are deficient to combine the expression of maintenance task and maintenance action simulation. Therefore, MTN (maintenance task net) was proposed in order to solve the integration of maintenance task description and maintenance action simulation.The framework of MTN including definition module, drive module and control module was constructed. The three key factors of MTN including state, action and condition based on the style of Petri net was biult. State could define maintenance resources such as human, tools and equipments.Action could define simulation process of behavior.Condition decided the constraint of state and action. MTN could drive virtual scene display system to run simulation and also could control the whole process. A case of LRU(line replaceable unit) disassembly was applied and the result proves that MTN model is valuable for the simulation and analysis of maintenance task.
