| Abstract: | Concerning the problems of designing and modeling the process of Point-Of-Care Testing (POCT) system, a method for concurrence system modeling and analyzing based on Time-Petri Net (TPN) was proposed which built more accurate information model for the process designing of POCT system. The activity holding duration was introduced into classical TPN, and the TPN modeling method for POCT control process was proposed. The scheduling simulator embedded in Petri net model was also designed for assisting the analysis, and optimization of the POCT control process. The simulation results show that the proposed modeling method for TPN can satisfy the practical requirement of process modeling of the parallel multi-class POCT control system in the fields such as reachable nodes and running time and provide powerful tool for process simulation and analysis. Furthermore, the proposed TPN can assist the system designer for the optimization of POCT system. |
