The Sequential Probability Ratio Test (SPRT) is widely used in the field of reliability and quality control. This paper is a continuation and a significant extension of the authors' earlier paper; it is dedicated to various risk ratios (α/β) and wi

The sequential comparison test is a tool for evaluation of the operational innovation in information technology service delivery processes. Due to the strong variability of these processes, the evaluation is done in comparison with the parallel runni

This paper deals with development of a sequential test for comparison of the mean times between failures (MTBF) of two items: a new one (subscript n) and another serving as a reference (subscript ref). In the test, the hypothesis is checked that MTBF

PurposeThis paper aims to propose a methodology for planning of a truncated sequential probability ratio test (SPRT) in which two systems with exponentially distributed times between failures (TBFs) are compared. The study is concerned with tests wit

A planning methodology is proposed for the sequential probability ratio test (SPRT) for the purpose of practical application. The SPRT is the most common acceptance test in the field of reliability and quality control. In it, the hypothesis is checke

An improvement of IEC-61123 in the field of sequential probability ratio test (SPRT) is proposed. The current standard does not provide a proper solution for modern industry's needs, and the test plans are not up-to-date with the knowledge in the are

A sequential probability ratio test (SPRT) is discussed, for comparison of two systems, one "basic" (b), and the other "new" (n), with exponentially distributed times between failures (TBF). The hypothesis that the mean TBFn/MTBFb ges 1 is checked, v

This paper presents results of an analysis of the sequential test (ST) procedures described in MIL-HDBK-781A, and IEC 61124, intended for checking the mean Time Between Failures (TBF) value under an exponential distribution of the TBF. The methodolog

This study deals with simultaneous testing of two systems, one "basic" (subscript b), and the other "new" (n), both with an exponential distribution describing the times between failures. We test whether the mean TBFn/MTBFb ratio equals a given value

The proposed method, General Cross-Correlation Process Control (GCCPC), is intended for timely detection of hacker attacks and faults, before they become critical and disrupt the normal activity of a web server. It is based on observation of the corr
