In the subsystems of eliminations of vulnerabilities and queues of unauthorized access considered as multichannel queueing systems with corresponding servers and queues, at random times there come requests to fix threats detected by the system. It is supposed that flows of requests demanding to eliminate threats coming to the mentioned subsystems of queueing systems are described with the Poisson distribution of probabilities, but processes of their elimination obey exponential law. For the system described above, there has been developed software realization of graphical interface which allows easily to change input parameters and observe graphical reflection of changes of the output indicators of the system.展开更多

Since CPS includes physical components, time and space constraints seriously challenge architecture study. In this paper, a service-oriented architecture of CPS was presented. Further, a two-way time synchronization algorithm for CPS service composition was put forward. And a formal method, for judging if actual CPS service meets space constraints, was suggested, which was based on space-π-calculus proposed. Finally, a case study was performed and CPS business process designed by the model and the proposed methods could run well. The application of research conclusion implies that it has rationality and feasibility.展开更多
