An ideal network troubleshooting system would be an almost fully automated system, monitoring the whole network at once, feeding the results to a knowledge-based decision making system that suggests actions to the operator or corrects the failure automatically. Reality is quite the contrary: operators separated in their offices try to track down complex networking failures in their own way, whi...

A new type of software framework for error troubleshooting in flexible manufacturing systems using a frame marker device. Our framework system meant to resolve the failures originated from the human-machine interface and to generate self-training from previous experience. Keywords—flexible manufacturing cell;error troubleshooting; augmented reality; software; framework.

Troubleshooting problems in real manufacturing environments impose constraints on admissible solutions that make the computational solutions offered by “troubleshooting from first principles” and the conventional experience based expert systems approaches infeasible. In this paper we present a computational theory for a solution to these problems that is based on the Principle of Locality and e...

model or time remaining. The planner is designed to be generic to tutors that teach troubleshooting for complex physical devices. It controls the Lower Hoist Tutor, a prototype tutor for the Mark-45 naval gun mount. This tutor teaches troubleshooting of the lower hoist, a complex hydraulic-electronic-mechanical assembly of the Mark-45 The tutor implementation demonstrates the planner’s operatio...

This licentiate thesis considers computer-assisted troubleshooting of complex products such asheavy trucks. The troubleshooting task is to find and repair all faulty components in a malfunc-tioning system. This is done by performing actions to gather more information regarding whichfaults there can be or to repair components that are suspected to be faulty. The expected cost of the<...
