Work ow systems hold the promise of facilitating the everyday operation of many enterprises and work environments. As a result, many commercial work ow management systems have been developed. These systems, although useful, do not scale well, have limited fault-tolerance, and are in exible in terms of interoperating with other work ow systems. In this paper, we discuss the limitations of contem...

The main aim of the distribution companies is to reduce their operating costs to get ahead of competition. One of the most popular approach is to increase the degree of reliability of distribution system. The management of network defeats (e.g. earth fault, short circuits) offers a lot of feasibilities for automation. The main jobs are fault localization, fault detachment and system refurbishin...

The need for a separate fault-management system, that is able to carry out both failure detection and reconfiguration, is becoming imperative due to the increasing complexity of fault-tolerant distributed applications. Such practice would eliminate the intricacies of the failure detection mechanisms from the application and would avoid repeating them in every program. The dependability of such ...

In this paper we present the initial specification of a system that covers both the control and management planes of network operation, with emphasis on fault, performance, and configuration management. The system incorporates rapid and reliable ATM network layer selfhealing mechanisms, intelligent load balancing, dynamic routing and resource management functions all interworking together with ...

After an incipient fault mode has been detected a logical question to ask is: How long can the system continue to be operated before the incipient fault mode degrades to a failure condition? In many cases answering this question is complicated by the fact that further fault growth will depend on how the system is intended to be used in the future. The problem is then complicated even further wh...

Systems with high dependability requirements are increasingly relying on complex on-line fault management systems to function in a wide range of scenarios. Fault management systems involve a combination of multiple steps – monitoring, data analysis, planning and execution – that are typically independently developed and optimized. We argue that it is inefficient and ineffective to improve any p...

Management policies can be used to specify requirements about the desired behaviour of distributed systems. Violations of policies (faults) can then be detected , isolated, located, and corrected using a policy-driven fault management system. Other work in this area to date has focused on network-level faults. We believe that in a distributed system it is more appropriate to focus on faults at ...

Sucker-rod pumping system operating status fault diagnosis technology is closely related to the energy consumption, production per well and the cost of crude oil exploration. But the knowledge depiction of the expert diagnostic system is mainly based on the production rules, neural networks or object-oriented. As ontology has advantages in hierarchy and semantic relationships expressing, it is ...

In this paper, a logic-based approach to automated system management is described. In particular, we focus on model-based fault diagnosis and fault correction based on planning.

Consider a system composed of N nodes that can be faulty or fault-free. The purpose of distributed system-level diagnosis is to have each fault-free node determine the state of all nodes of the system. This paper presents a Hierarchical Adaptive Distributed System-level Diagnosis (Hi-ADSD) algorithm, which is a fully distributed algorithm that allows every fault-free node to achieve diagnosis i...
