Economic design of a variable sampling rate EWMA chart.
May 1, 2004... 1. Introduction In production processes control charts are widely used in monitoring to detect changes in process parameters. The traditional approach to sampling for a control chart is to use a Fixed Sampling Rate (FSR) in which we use a...

Statistical process control via context modeling of finite-state processes: an application to production monitoring.
May 1, 2004... 1. Introduction and literature review In many industrial environments process outputs are often adjusted by applying feedback mechanisms and policies. As an example, the temperature in a chemical reactor is controlled by a thermostat;...

A cautious minimum variance controller with ARIMA disturbances.
May 1, 2004... 1. Introduction Due to a number of factors, of which Box and Kramer (1992) provides an excellent discussion, Engineering Process Control (EPC) is an increasingly common tool for complementing statistical process control (SPC) in efforts to...

Multiresponse systems optimization using a goal attainment approach.
May 1, 2004... 1. Introduction Response Surface Methodology (RSM) (Box and Draper, 1987; Khuri and Cornell, 1996; Myers and Montgomery, 2002) is increasingly being used in various industries (semiconductor, chemical, food industry, etc.) for quality...

Optimization design of control chart systems.
May 1, 2004... 1. Introduction The fabrication of a product usually includes many process stages. The integration of all these stages results in a manufacturing system. Specifically, in the manufacture of a mechanical part, each stage corresponds to the...

Human performance reliability: on-line assessment using fuzzy logic.
May 1, 2004... 1. Introduction Physiological, psychological and physical factors all influence human reliability. Over the years, many approaches to human reliability assessment have been proposed (Swain and Guttmann, 1983; Embrey et al., 1984; Hannaman...

Algorithms to determine the threshold reliability of flow networks.
May 1, 2004... 1. Introduction With increasing emphases on better and more reliable services, many systems (such as computer and communication systems and transportation systems) have incorporated reliability analysis as an integral part in their...

An upper bound on the weight-balanced testing procedure with multiple testers.
May 1, 2004... 1. Introduction In this paper we analyze the Weight-Balanced Testing (WBT) algorithm with multiple testers. We start by exemplifying the sequential search problem as presented in Ahlswede and Wegner (1987) and Yeung (1991). Consider a...
