Abstract
To run a production processes an appropriate target for the process mean has to be fixed, for presenting process capability a suitable target for a process capability index has to be selected. Generally, the two targets are fixed independently. This paper presents a method which combines both targets with respect to process mean and process capability under a fuzzy environment. By defining linear membership functions for relaxing the strict conditions on the above given two targets, a minimax approach is used for obtaining a solution of the problem.
