A solid state relay (SSR) is an electrical ON-OFF control device through which the delivery of electrical power to loads is switched either ON or OFF by a small control signal. The device serves the same function as a classical electromechanical relay (EMR) but carries no mechanical switching...

Through listening to the voice of the customer, quality function deployment (QFD) is a systematic methodology for quality improvement and product development. The quality of a product or service is ultimately judged in terms of customer satisfaction. Customer satisfaction benchmarking can help...

Under rapidly changing and highly competitive circumstances, the timely design, development and marketing of new products or services with creative and innovative features are essential for a company’s survival. In order to capture and retain market share, customer requirements and...

Abstract Control charts for high quality processes based on counting cumulative conforming items have attracted a lot of attention recently. However, such charting procedures usually apply when items are inspected one by one. There are situations that products are inspected sample by sample for...

To achieve quality in customer service is to enhance a company’s competitiveness. With the birth of the World Wide Web, the process of making products and services available to customers has changed from traditional communication channels to Web‐based information systems. Consequently, the...

For high-quality processes, non-conforming items are seldom observed and the traditional p (or np) charts are not suitable for monitoring the state of the process. A type of chart based on the count of cumulative conforming items has recently been introduced and it is especially useful for...

Topp-Leone distribution is a continuous unimodal distribution with bounded support (recently rediscovered) which is useful for modelling life-time phenomena. In this paper we study some reliability measures of this distribution such as the hazard rate, mean residual life, reversed hazard rate,...

High-yield production processes that involve a low fraction non-conforming are becoming more common, and the limitations of the standard control charting procedures for such processes are well known. This paper examines the control procedures based on the conforming unit run lengths applied to...

Purpose – Planning and control of humanoid biped walking has been an active research topic for many years. But, there is no definite answer to the question of how to practicre‐examinedally achieve speedy and stable walking in real‐time and in a changing environment. The purpose of this...
