基于MTN的维修工作建模与仿真技术研究

维修工作过程模型是维修性与维修工作分析与评定的重要基础和手段，现有的建模技术在描述维修过程以及维修过程的相关信息等方面不够直观、也不够丰富。基于Petri网的建模概念，提出了一种用于描述维修工作过程的建模技术——维修工作网（Maintenance Task Net，MTN）；详细叙述了通过维修工作组成元素和维修工作过程关系描述维修工作过程的方法；提出了针对不同维修工作的初始信息进行维修工作建模的两种建模方式；基于该建模技术，开发了软件工具在维修工作分析、虚拟维修仿真中进行了应用研究，验证了MTN的实用性。

Modeling And Simulating Technology of Maintenance Task based on MTN

Maintenance task process model is the important basis and method for maintainability and maintenance task analysis and evaluation, the modeling technology in existence is nor intuitionigtic or abundance for describing maintenance process and the information concerned. Based on Petri Net, a modeling technology--Maintenance Task Net is presented for describing maintenance process. The method is recounted, which makes use of maintenance task cells and task relationships. Two modeling modes are presented for different initial information of maintenance task. Based on the modeling technology, a software is developed and some applied research works are carried out in MTA( Maintenance Task Analysis) and VM( Virtual Maintenance) ,and the practicability of MTN is validated.
