Abstract

Statistics process control (SPC)is one of the crucial methods securing product quality and reliability in modern production, and process capability index is an important indicator mostly used in SPC. Process capability index is a degree in which, using the ratio of process specifications´ upper limit and low limit to the actual change range (indicated by 6σ), to measure a process meeting requirement of the product capability indicators. SPC´s main aim is to be able to keep comparatively small change round the given target for the process. Besides process capability index, SPC should concern process target that would not be precise. This paper shows the process control of minimax based on the process target and on process capability index, in fuzzy environment.
