Through the dynamification of testing intervals the flexibility level of confirmation systems for measuring equipment can be increased considerably. Since confirmation of inspection, measuring and testing equipment is a significant part of quality management and an essential requirement for the entire production process, especially with the increasing demands of micro- and nanotechnology, it is absolutely necessary to increase the efficiency of confirmation systems. Through a special method developed for this purpose, the flexibility level and efficiency of confirmation systems can be achieved and the expenses can be substantially reduced by the use of fuzzy logic for dynamification of testing intervals.
