The paper presents a combined model of reliability and performance (performability model) of two modules in series, each has C components in parallel. The objective of the paper is to illustrate the effect of the reliability on the performance. The paper emphasizes homogeneous continuous-time...

This note investigates the problem of minimizing the average fraction inspected (AFI) for a CSP – V plan. A solution procedure is developed to find the sampling plan parameters that meet the average outgoing quality limit (AOQL) requirement, while minimizing the AFI when the process average (...

A performance capability measure is proposed that is useful in a wide class of production processes. Traditional quality improvement methodologies concentrate on getting the process right in order to meet the capability requirements of the product immediately after production, as measured for a...

In this paper mixed acceptance sampling procedures are analyzed which combine methods of process control and acceptance sampling for arriving at an efficient and cost-reduced way of performing the control of outgoing or incoming lots of product. The resulting plans are called mixed sampling plans.

This paper presents a correction plan for maintaining high quality level of production processes. The Graphical Evaluation and Review Technique (GERT) is applied to model and analyze the dynamic characteristic of the plan. Unity values are tabulated to facilitate operation and construction of plans.

Neyman prediction and measurement procedures have been discussed by E.v. Collani, M. Dumitrescu and their co-workers since 1999. These procedures offer optimal, however, computational rather intensive ways for predicting with respect to the future outcome of a random variable and measuring with...

Industrial quality control is necessary at least for two reasons:Monitoring product or process quality in order to perform interventions for assuring a desired quality level.Monitoring product or process quality in order to meet certain requirements (imposed by law or customers) for documentation.

This paper compares semi-economic -control charts and -R control charts assuming two different discrete distributions for the length of the in-control period of a production process with regeneration points given by the alarms signals. Sample sizes and control limits for a set of parameters are...

We study a nonparametric sequential detection procedure, which aims at detecting the first time point where a drift term appears in a stationary process, from a Bayesian perspective. The approach is based on a nonparametric model for the drift, a nonparametric kernel smoother which is used to...
