Three reliability engineering techniques and their application to evaluating the availability of IT systems: An introduction
نویسندگان
چکیده
D. Bailey E. Frank-Schultz P. Lindeque J. L. Temple III We present a brief introduction to three reliability engineering techniques: failure mode, effects, and criticality analysis; reliability block diagrams; and fault tree analysis. We demonstrate the use of one of these techniques, reliability block diagrams, in evaluating the availability of information technology (IT) systems through a case study involving an IT system supported by a three-tier Web-server configuration.

Comparative analysis of profit between three dissimilar repairable redundant systems using supporting external device for operation
The importance in promoting, sustaining industries, manufacturing systems and economy through reliability measurement has become an area of interest. The profit of a system may be enhanced using highly reliable structural design of the system or subsystem of higher reliability. On improving the reliability and availability of a system, the production and associated profit will also increase. Re...
متن کاملAn Optimal Preventive Maintenance Model to Enhance Availability and Reliability of Flexible Manufacturing Systems
General preventive maintenance model for the components of a system, which improves the reliability to ‘as good as new,’ was used to optimize the maintenance cost. The cost function of a maintenance policy was minimized under given availability constraint. On the other hand, in order to ensure appropriate reliability and availability, the development of the optimal maintenanc...
متن کاملAnalysis of the Reliability of a Three-Component System with Two Repairmen
In this paper authors have considered a system having three units A, B1 and B2. A is controlled by a controller and B1 and B2 are independent. Two repairmen are involved in repair of the system. One of the repairmen (the first) is the foreman (boss) and the other an assistant (apprentice). Whenever any unit fails, repair is undertaken by boss. If the boss is busy in repairing and at the same ti...

متن کاملImprovement of the Reliability of Automatic Manufacture Systems by Using FTA Technique
In recent years, Many manufacturing industries for promoting their efficiency have tended to use the automatic manufacturing systems. Expanding automatic systems and to increase their complexity are representing the necessity of studying a proper functional quality and using reliable equipment in such systems more than ever. In this direction, the technique of fault tree analysis (FTA), along w...
