Computation of Diagnosable Fault-Occurrence Indices for Systems with Repeatable-Faults

Proceedings of the 44th IEEE Conference on Decision and Control, 2006
We study discrete-event systems prone to such faults which can occur repeatedly. For the diagnosis of re- peatable faults, [5] introduced the notion of l-diagnosability requiring the diagnosis of the lth occurrence of a fault within a bounded delay.

Design of fault diagnosable and repairable PLA's

IEEE Journal of Solid-State Circuits, 1989
Presents a complete fault-tolerant programmable logic array (PLA) design that includes both fault diagnosability and repairability. The proposed PLA design is capable of detecting, locating, and repairing single and multiple stuck-at, bridging, and crosspoint faults.

Intermittent Fault Diagnosability of Interconnection Networks

Journal of Computer Science and Technology, 2017
An interconnection network’s diagnosability is an important metric for measuring its self-diagnostic capability. Permanent fault and intermittent fault are two different fault models that exist in an interconnection network. In this paper, we focus on the problem pertaining to the diagnosability of interconnection networks in an intermittent fault ...

Diagnosing scan chain faults

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 1994
Testing screens for good chips. However, when test fall out is high (low yield) it becomes necessary to diagnose faults so that the manufacturing process or physical design can be filed to improve yield. Several scan based diagnostic schemes are used in industry. They work when the scan chain itself is fault free.

Diagnosing faults in electrical transmission networks

1999 European Control Conference (ECC), 1999
This paper describes a model-based diagnostic system for diagnosing faults in Electrical Transmission Systems. It checks the timing of the operation of network equipment against its Augmented Reactive Models (ARM). These ARM are finite state machine models extended to allow transitions to be conditioned on time intervals specified relative to the ...

Learning, indexing, and diagnosing network faults

Proceedings of the 15th ACM SIGKDD international conference on Knowledge discovery and data mining, 2009
Modern communication networks generate massive volume of operational event data, e.g., alarm, alert, and metrics, which can be used by a network management system (NMS) to diagnose potential faults. In this work, we introduce a new class of indexable fault signatures that encode temporal evolution of events generated by a network fault as well as ...

A New Measure for Hybrid Fault Diagnosability

IEEE Transactions on Computers, 1987
Using the PMC model of a multiprocessor system, a new, general quality of hybrid fitult (combinations of hard anid soft failing units) diagnosability is characterized which encompasses previously known results as well as provides a major extension.

On the Design of Multiple Fault Diagnosable Networks

IEEE Transactions on Computers, 1971
This paper considers the design of diagnosable combinational networks. The diagnosability criterion used here requires that the single fault detection test set for the network also detects all multiple faults. Several recent studies in the area of multiple fault diagnosis are reviewed and the results which are pertinent to this investigation are ...

System Fault Diagnosis: Closure and Diagnosability with Repair

IEEE Transactions on Computers, 1975
Determination of the detectability and diagnosability of a digital system containing at most t faulty system components is considered. The model employed is to an extent independent of the means used to implement diagnostic procedures, i.e., whether the tests are accomplished via hardware, software, or combinations thereof.

Diagnosing Transformer Faults with Petri Nets

2004
Transformer fault diagnosis and repair is a complex task that includes many possible types of faults and demands special trained personnel. In this paper, Petri Nets are used for the simulation of transformer fault diagnosis process and the definition of the actions followed to repair the transformer.
