Optimization of fault management system in power plants based on DD-RCM and TPN

A method of optimizing the fault management system in power plants based on DD-RCM （resultchain based modeling for digital developing） and TPN （temporal Petri net） is proposed. First, the model of the fault management system was set using DD-RCM. Then, it was transformed to the temporal Petri net model by corresponding rules. Secondly, relationships among all the activities, such as choice, conflict, synchronization and concurrency, were confirmed according to the Petri net model and described employing the reengineering algorithm of incidence matrix. Thirdly, the Petri net model was reduced by combining reduction rules and conflict, synchronization relationships to optimize the fault management system in power plants. Finally, the functionality of the reduced net was proved by the temporal logic of the temporal Petri net.

基于DD-RCM和集控Petri网的产品生产过程研究

提出一种描述以及优化企业产品生产过程的方法。首先,用DD-RC方法建立企业产品整个生命周期的模型,并将DD-RC模型转换为集控Petri网模型;其次,根据Petri网模型确定出企业生产过程中各种活动之间的选择、冲突、同步和并发关系。进一步用关联矩阵的重组算法对各种关系加以描述。再次,对企业生产过程进行优化和整合。最后,以产品生命周期模型为例,阐明了本文方法的可行性及有效性。
