The use of control charts for monitoring schemes in medical context should consider adjustments to incorporate the specific risk for each individual. Some authors propose the use of a risk-adjusted survival time cumulative sum (RAST CUSUM) control ch

The aim of this paper is to propose a new attribute control chart, namely MaxD, to monitor a bivariate process mean. No measurement is taken but using a gauge ring each sampled unit is classified as failed/disapproved or not in each dimension. If the

This paper proposes a new combined control chart for monitoring the mean of a process. A sample of size n is split into two sub-samples of sizes n1 and n2 = n - n1, determined by an optimization search. The units of the first sub-sample are evaluated

An alternative model for an on-line monitoring process for variables is presented in this paper. The characteristic of interest follows a normal distribution and changes of the distribution parameters are described by a two-state Markov chain. Items
