The global competition requires and the improved possibilities of data collecting and data analysis enables implementation of so-called continuous improvement strategies. Such a strategy can be divided into two parts, one which identifies room for improvement and a second one which takes care of...

In a production process, when quality of the product depends on more than one characteristic, ‘Multivariate Quality Control’ (MQC) techniques are used. Many MQC techniques have been developed to control multivariate variable processes, but not much work has been reported on multivariate...

In this paper recent results related to run and frequency quotas in time-homogeneous multi-state Markov chains are presented and their application in terms of the classical risk model is given.

This paper discusses several designing procedures for chain sampling inspection plan (ChSP-1) for given values of AQL and LQL and with associated requirements with respect to the risks. Though, these procedures differ methodologically in arriving at solutions, their common primary aim refers to...

This article deals with estimation of the change-point in a sequence of independent random variables. It is based on a least squares process endowed with a weight function. For finite sample sizes we derive bounds of the error probability. They immediately yield rates of consistency which are...

Without any particular notice of the worldwide scientific community, two anniversaries of one of the greatest - if not the greatest - heroes of humanity went by this year. 350 years ago the theologian, natural scientist and mathematician Jakob Bernoulli was born in Basel, and 300 years ago,...

In the past years many companies in the US and Europe have embraced a quality management initiative based on the concept and metrics of “Six Sigma”. Developed as an internal company strategy at Motorola, it was put into action as a quality management program at General Electric and other big...

A procedure is derived for determining the values of the parameters of a multinomial distribution by means of the fiducial approach proposed by Fisher. By decomposing the involved probability (mass or density) functions, it is shown that the resulting fiducial distributions belong to the...

In the area of stress-strength models there has been a large amount of work as regards estimation of the reliability R = Pr(X Y). The algebraic form for R = Pr(X Y) has been worked out for the vast majority of the well-known distributions when X and Y are independent random variables belonging...
