Recent Advances and Future Directions for Quality Engineering

Abstract

The origins of quality engineering are in manufacturing, where quality engineers apply basic statistical methodologies to improve the quality and productivity of products and processes. In the past decade, people have discovered that these methodologies are effective for improving almost any type of system or process, such as financial, health care, and supply chains.This paper begins with a review of key advances and trends within quality engineering over the past decade. The second part uses the first part as a foundation to outline new application areas for the field. It also discusses how quality engineering needs to evolve in order to make significant contributions to these new areas.

New control charts for monitoring the Weibull percentiles under complete data and Type‐II censoring

“…Control limits are determined at a given ARL 0 . Moreover, the Fredholm integral equation of the second kind is used to numerically compute the ARL 1 .…”

“…Recently, Vining et al suggested that there is a strong need to develop process control techniques for reliability data to ensure that the product/process maintains the expected reliability standard. Li and Kong noted that the techniques which have been proposed to monitor the occurrence rate of nonconforming items can be viewed as monitoring failure events.…”

A double exponentially weighted moving average chart based on likelihood ratio for monitoring an inflated Pareto process

“…In the food industry, quality characteristics include sensory properties such as flavor, color, aroma, taste, and texture; quantitative properties namely, percentage of a certain ingredient, weight, length and width of a certain product, etc . Vining et al stated that the food industry is a potential area for the application of statistical process improvement approaches. Statistically monitoring food quality characteristics is essential.…”

Bootstrapping Analysis of Lifetime Data with Subsampling

“…Greater emphasis on reliability is one of the future directions for quality engineering . Vining et al .…”

“…Greater emphasis on reliability is one of the future directions for quality engineering. 5 Vining et al 6 noted that current practice almost exclusively restricts the use of experimental protocols in reliability testing to completely randomized accelerated life tests. The future will see more broad scale use of basic experimental designs, analyses, protocols, and concepts.…”
