Reliability and availability have always been important characteristics of systems but become even more critical and complex issues on networks. Due to the high complexity of accurate calculation methods, simulation methods for network reliability and availability evaluation have been a popular area of research, and received significant attention. In this paper the network topology model, the failure...
In order to solve the problem of collaborative relationship between entities in the management mode of organization coordination network (OCN) of major scientific and technological project (MSTP) based on authority links, we use systems engineering integrated, project management and calculation organization theory. We do the quantitative measurement of network and depict the corresponding mode view,...
Fault forecasting is very important to establish accurate maintenance support plan, reduce maintenance support cost, improve operational readiness rate and mission dependability rate, even avoid the huge loss for missile equipment; To resolve the problem of new-style missile equipment fault forecasting difficultly, which is induced by the complexity of system compose, fuzziness of configuration connection...
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...
This paper proposes a new approach to reliability modeling for units subjected to ramp-stress accelerated degradation test. The new approach is derived from cumulative damage theory and a Proportional Degradation Hazard Model. Step-stress approximation method is used. A numerical example is given to illustrate this approach.
Maintenance resources are the important part of the equipment support system and essential for the equipment maintenance. Maintenance resources can be classified into consumed resources and occupied resources. To effectively handle the consumed resources inventory control, a series of inventory models for consumed resources in a multi-echelon support system were proposed, which includes stock dynamic...
