Extending trouble ticket systems to fault diagnostics
TLDR
Current research trends towards understanding and implementing these advanced functions in network management platforms to effect automatic trouble ticket generation, fault diagnostics, and the correlation of multiple views network problems and behavior are described.Abstract:
Network management in large heterogeneous communication environments requires the incorporation of more advanced tools than are currently available, especially in the area of fault management. By providing an informational infrastructure for documenting network behavior and maintenance activities, TTSs (trouble ticket systems) have provided some relief for the fault management problem. Researchers have recognized TTSs as a means for realizing more advanced functions in network management platforms to effect automatic trouble ticket generation, fault diagnostics, and the correlation of multiple views network problems and behavior. The authors describe current research trends towards understanding and implementing these advanced functions in a TTS framework. >read more

Distributed Systems for System Architects
Paulo Veríssimo,Luís Rodrigues +1 more
TL;DR: The distributed systems architect assembles pieces of hardware that are at least as large as a computer or a network router, and assigns pieces of software that are self-contained - such as Java applets - to those hardware components.

Method and apparatus for resolving faults in communications networks
TL;DR: In this article, the authors propose an improved method and apparatus of resolving faults in a communications network using a trouble ticket data structure to describe communications network faults, where completed trouble tickets are stored in a library and when an outstanding communication network fault is received, the system uses at least one determinator to correlate the outstanding communications network fault to data fields in the set of data fields of the data structure.

Outline of a New Approach to the Analysis of Complex Systems and Decision Processes
TL;DR: By relying on the use of linguistic variables and fuzzy algorithms, the approach provides an approximate and yet effective means of describing the behavior of systems which are too complex or too ill-defined to admit of precise mathematical analysis.

Fuzzy logic in control systems: fuzzy logic controller. II
TL;DR: The basic aspects of the FLC (fuzzy logic controller) decision-making logic are examined and several issues, including the definitions of a fuzzy implication, compositional operators, the interpretations of the sentence connectives 'and' and 'also', and fuzzy inference mechanisms, are investigated.
