A High-Level Fuzzy Timed Petri-Net-Based Approach

摘要

In order to deal with the uncertain temporal knowledge of the complex real-time system and to improve the existed uncertain temporal knowledge expression and inference algorithm, a new kind of high-level fuzzy timed Petri nets was proposed based on fuzzy timed Petri nets (FTN). The uncertain temporal of the complex real-time can be quantitatively described and the time possibility can be analyzed after temporal constraint was added to resources and transitions of FTN. Finally, a case study was given to illustrate the usage of this approach. The temporal phenomena and laws of real-time system can be described more overall with HFTN. It is suitable for complex real-time system modeling and analysis.
