Wykrywanie zmian struktury kosztów kontroli jakości z wykorzystaniem testów permutacyjnych

The quality control aiming to provide a desired level of quality of produced products, requires bearing significant expenses. The structure of expenditure spent on quality assurance, due to its multidimensional nature, should be known and constantly monitored in order to detect the changes taking place therein. In this paper a proposal for a method to verify the hypothesis about the stability of the cost structure is presented. The method applies a statistical testing procedure based on permutations. In the presented example the real data coming from the acceptance inspection carried out in factory in Silesia have been used.
