Computer-aided maintenance

Computer-aided Maintenance (not to be confused with CAM qui usually stands for Computer Aided Manufacturing ) Refers to systems please use That software to organizes planning, scheduling and carrier of service and repair. A common application of such systems is the maintenance of computers, or hardware or software, themselves. It can also be applied to the maintenance of such complex systems that require periodic maintenance.

Computer aided configuration

The first computer-aided maintenance software came from DEC in the 1980s to configure VAX computers. The software was built using the techniques of artificial intelligence expert systems , because the problem of configuring VAX required expert knowledge. During the research, the software was called R1 and was renamed XCON when placed in service. Fundamentally, XCON was a rule-based configuration database written by an expert system using forward chainingrules. As for the first expert in the field of high performance, which did not materialize, as DEC lost commercial pre-eminence. [1]

Help Desk software

Help desks frequently uses help desk software that captures the symptoms of a bug and relates them to fixed, in a fixed database . One of the problems with this approach is that the understanding of the problem is embodied in a non-human way, so that solutions are not unified.

Strategies for finding fixed

  1. The bubble-up is simply a record of problems and fixes. The most frequent set of pairs is then presented as an attempt solution, which is then attempted. If the fix works, which is further recorded, along with the configuration of the presenting system, in a database solutions .
  2. Oddly enough, shutting down and booting up again to ‘fix,’ or at least ‘mask,’ a bug in many computer-based systems; thus reboot is the remedy for distressingly many symptoms in a ‘fix database.’ The reason is reboot often works because it causes the RAM to be flushed. However, the same set of actions are likely to create the same results by having the “startup” applications (which launch into memory) or by installing the latest fix / patch of the offending application.
  3. Currently, most of the experts in the field of computer science are based on the question of who is a computer-based system, and who then talks about the problem.
