This work studies the effect of incorporating the 2-of-k, 3-of-k, and k-of-k runs rules into the one-sided bivariate generalized variance |S| control chart, in terms of the average run length (ARL). The Markov chain approach is used to obtain the ARL profiles for the proposed chart. From the ARL comparisons, the control charts with runs rules detect the process change faster than the corresponding...
The simulation of metal-forming process, in particular the hot rolling of steel, using model materials and scaled deformation conditions has been reviewed. It is shown that complete similarity cannot be achieved, with significant differences evident when simulating processes where the mechanisms of deformation are important. This, and difficulties in achieving friction conditions through lubrication,...
