... in these industries appear to have more problems with maintaining high quality levels. Design/methodology/approach The research studies the effects of increasing product variety and shortening product life cycles on one control system: quality management. Findings In situations of shortening product life...

...Zhang Wu Presents an approach to determine the optimum control limits of the x‐bar chart for skewed process distributions. The approach takes both the control limits of the x‐bar chart and the specification limits of x into consideration, and relates the out‐of‐control...

... the strength of support for the prevailing structures of ownership and control ‐ which remain largely unaddressed by quality initiatives because these structures are taken as given and are assumed to be legitimate. There are few examples where TQM has been introduced and workers have taken up places...

...René Gélinas Usually, statistical process control uses control charts for monitoring the evolution of a manufacturing process. Traditionally, control limits are computed without considering another aspect of statistical process control: the process capability (PC). This is essential information...

...Mamoun Al‐Salti; Anthony Statham The use of Statistical Process Control (SPC) techniques for monitoring manufacturing processes in mass production is relatively easy. In small‐batch manufacture, however, such techniques can be difficult to implement due to lack of sufficient data to establish...

...X. Ding; P.M. Frank Studies problems related to modelling, control and monitoring of circulatory systems with an artificial heart. First, presents a pulsatile model of cardiovascular systems. This model has a well‐grounded physiological basis and includes several reflex control systems...
