Abstract:
|
We propose and analyze a new chart for the multivariate process control of Poisson variables: the Linear Combination of Poissons (LCP) chart. The implementation parameters (coefficients of the linear combination and control limits) of this chart can be obtained running (in Windows) user-friendly software developed by the authors. The program employs genetic algorithms to minimize the out-of-control ARL for a given shift, under the constraint of a desired in-control ARL. The new chart shows very good performance when compared with its competitors. An EWMA version of it has also been developed.
