Reliability Analysis of Hierarchical Systems

摘要

The hierarchical nature of hierarchical systems helps in fault coverage. Modular imperfect coverage model (MIPCM) introduced the dependencies among components and/or modules across the different levels in the hierarchy that increased the complexity of solutions. Given complexity, the Upward Imperfect Coverage Model (UMIPCM) has been developed to more clearly represent the performance relationship between the respective layers and the overall system. Based on simple and efficient algorithm (SEA) idea, the result on the top down separable algorithm is obtained for the HS, Finally, the application value of this efficient algorithm is analyzed by a sample hierarchical system. The hierarchical system analysis approach is an important part of reliability engineering. The upward modular imperfect coverage model (UMIPCM) helps lower complexity of reliability analysis. The top down separable algorithm is efficient and integrated, helping a reliability engineer use existing software packages for fault-tolerant HS.
