Taking software project risk event as the study object, this paper focuses on the problem of emergency disposal of software project risk and Petri nets modeling method is introduced to analyze the concurrent progresses. According to the happened risks, its emergency management process is defined and its Petri nets model is built. Due to its homogeneous characteristics with Markov chain, its Markov...
This paper proposes the GSPN method to model auto product warranty service process to analyze its performance. On that basis, the GSPN model is developed and converted to Markov Chain for the GSPN is isomorphic with Markov Chain. With Markov Chain and corresponding mathematics method we obtain the main performance indexes of the process. The bottlenecks of the process are identified to provide the...
As an important performance of equipment system, testability is always omitted in the traditional availability analysis. Testability design is an effective way to realize the fault detection and isolation. Determining testability index is the chief step of testability design. It needs to consider the influence factors of testability such as the requirement of system availability, reliability, maintainability,...
With the modeling technology of Petri nets-based, task logics are described in products collaborative design. With boundedness, the coverability tree algorithm of Petri net is designed. On this basis, corresponding Markov chain is constructed; the algorithm of analysis performance of stochastic Petri net is provided. Through the case, the utilization ratio of resources and design efficiency in this...
During the life cycle of business process management, the quantitative analysis of the time performance measure is pivotal to guarantee the validity of process model and to improve its quality. Based on the characteristic of management processes and the assumption that the processing time of activities is either zero or a stochastic variable obeying the exponential distribution, the generalized stochastic...
