Reliability Sampling Procedure For High Priced Products

Sampling procedure

High-priced technology can be good value for money.

M edical technology is now subject to the same economic scrutiny that was historically reserved for public health and disease prevention programs. It has long been true that vaccination, health education, and screening programs have been required by both public and private health care agencies to prove their economic worth before they could be funded. A frequently encountered criterion for fund...

A Sequential Sampling Procedure for Stochastic Programming

We develop a sequential sampling procedure for a class of stochastic programs. We assume that a sequence of feasible solutions with an optimal limit point is given as input to our procedure. Such a sequence can be generated by solving a series of sampling problems with increasing sample size, or it can be found by any other viable method. Our procedure estimates the optimality gap of a candidat...

A Sequential Sampling Procedure for Genetic Algorithms

In this paper, we apply sequential decision theory for scheduling tests in genetic algorithms and investigate an efficient sampling procedure for improving its performance. We use a loss function specifically defined for our analysis and obtain sequential decision equations for the optimal procedure. We derive simplified equations so that the procedure can be applied in practice. Finally, we co...

Belief reliability: a new metrics for products' reliability

Traditional reliability metrics are based on probability measures. However, in engineering practices, failure data are often so scarce that traditional metrics cannot be obtained. Furthermore, in many applications, premises of applying these metrics are violated frequently. Thus, this paper will give some new reliability metrics which can evaluate products’ reliability with few failure data. Fi...
