A Component-Testing Procedure For A Parallel System With Type II Censoring

We consider the problem of acceptance testing for a parallel (1-out-of-n:G) system of n different components with constant failure rates. The components are individually tested and the tests are terminated as soon as a preassigned number of each component fails. This paper provides a criterion for accepting or rejecting the system based on the product of the total times on test for each component. The critical level for the test statistic is chosen so as to guarantee that the specified levels of consumer and producer risks on the system reliability are not exceeded. If the testing costs depend on the number of each component tested, aminimum-cost procedure can be found from the feasible set of plans.

A Rapid Algorithm For Reliability Optimisation Of Parallel Redundant Systems

A rapid method is proposed for optimization of reliability of multiconstraint parallel redundant systems. The constraints need not be linear. This method provides good starting values, which are close to the boundary of the feasible region, for the number of redundant units in each subsystem. No proof has been presented to establish the optimality obtained by this method. Yet for examples tried out this method provides optimal or near optimal solutions.

Optimal Inspection Policy For Multistage Production Process With Alternate Inspection Plans

This paper considers a multistage production process with alternate inspection plans. At each stage a number of alternate inspection plans with different cost and reliabilities may be available. Since more reliable inspections are more costly it is essential to find out a compromise between the reliability and cost. A mathematical model is developed. Dynamic programming is used to determine at each stage that out of the available inspection plans (including the case of no inspection) which one will result in minimum s-expected total cost per item.

A Tri-State Oriented Parallel Processing System

An ``Alternating Sequential/Parallel' system, the Mopps was introduced a few years ago and is modified despite the fact that it solved satisfactorily a number of real-time problems. The new system, the ``Topps' is described and compared to Mopps in Section II and two applications are chosen to prove it to be superior. In Section III, the advantage of having a third basic, the ``ring' mode, is illustrated when solving sets of linear equations with band matrices. In Section IV, the advantage of having independent I/O for the slaves is illustrated for biomedical signal analysis.
