some applications are critical and must designed fault tolerant system. usually voting algorithm is one of the principle elements of a fault tolerant system. two kinds of voting algorithm are used in most applications, they are majority voting algorithm and weighted average algorithm these algorithms have some problems. majority confronts with the problem of threshold limits and voter of weight...

The Orbital Cygnus vehicle is being developed to perform autonomous rendezvous with International Space Station (ISS) and to provide cargo services to the faculty. Safety through fault management has been a primary consideration in the design of the trajectories, GN&C algorithms, and software. This paper describes the approach used to design and validate a fault management system required to me...

For the four processes of aero engine health management, which are composed of condition monitoring, diagnostics, prognostics and prescriptive action, a four-layer architecture of aero engine health management divided into data layer, transaction layer, decision layer and users layer, is designed based on multi-agent. Corresponding to the function of each layer, six agent roles are defined, suc...

Abstract. In this paper we discuss the perspectives that should be taken into account by the research community while trying to evolve Fault-Management towards Autonomic Fault-Management. The well known and established FCAPS Management Framework for Fault-management, Configuration-management, Accounting-management, Performance-management and Security-management, assumes the involvement of human...

Generalized Multi-Protocol Label Switching (GMPLS) is currently under standardization. It basically reuses the MPLS control plane (IP routing and signaling) for various technologies such as fiber switching, DWDM, SONET, and packet MPLS. Since GMPLS runs in core networks, fault management is of major concern. However, fast fault recovery and backup capacity assignments are very expensive and not...

This study proposes a network traffic monitoring system that will support the operation, management, expansion and design of a network system for its users through an analysis and diagnosis of the network-related equipments and lines in the PC-room. The proposed monitoring system is lightweight for its uses under the wireless environment and applies a web-based technology using JAVA to overcome...

Software systems are known to suffer from outages due to transient errors. Recently, the phenomenon of “software aging”, one in which the state of the software system degrades with time, has been reported. To counteract this phenomenon,a proactive approach of fault management, called “software rejuvenation”, has been proposed. This essentially involves gracefully terminating an application or a...

Vehicle driveline system and its working accuracy play an important role in the performance of car. The purpose of this study is to provide an appropriate mechanism for investigating, identifying and determining the position and size of defects in the vehicle power transmission system. This is based on the patterns of the residual signal, obtained from a simulated model of the system. Neuro-...
