Recent work has raised the challenge of efficient automated troubleshooting in domains where repairing a set of components in a single repair action is cheaper than repairing each of them separately. This corresponds to cases where there is a non-negligible overhead to initiating a repair action and to testing the system after a repair action. In this work we propose several algorithms for choo...

The mobile telecommunication industry has experienced a very rapid growth in the recent past. This has resulted in significant technological and architectural evolution in the wireless networks. The expansion and the heterogenity of these networks have made their operational cost more and more important. Typical faults in these networks may be related to equipment breakdown and inappropriate pl...

Fault tree analysis is often used in elevator fault diagnosis because of its simplicity and reliability. However, the traditional method has problems low efficiency due to ignoring location change bottom events during troubleshooting. This paper proposes a rapid based on multiattribute decision making solve problem. The system constructed expert knowledge multisource data, location-related matr...

Technical support contributes 17% of the total cost of ownership of today’s desktop computers [12], and troubleshooting misconfigurations is a large part of technical support. For information systems, administrative expenses, made up almost entirely of people costs, represent 60–80% of the total cost of ownership [5]. Prior work [21, 24] has created promising tools that automate troubleshooting...

Experienced oncology nurses use different troubleshooting techniques for clearing occluded central venous access devices (CVADs) with varying degrees of success. The purpose of this study was to explore troubleshooting techniques used for clearing occluded CVADs by experienced oncology RNs and identify the perceived effectiveness of each technique. An invitation for a web-based survey was sent ...
