Effectiveness assessment of functioning o 38 f quality assurance system
Journal Title: Production Engineering Archives - Year 2013, Vol 0, Issue 1
Abstract
This paper presents the results of six-year studies that were conducted in an iron foundry. The research consisted in effectiveness assessment of the quality assurance system. Determinants of three groups of estima-tion criteria were characterized. In technological criterion the required values of dimensional tolerance, the value of required hardness, ragged-ness, the required values of coefficients of the scattering process and also acceptable fractions of the products were taken into consideration. The economic criteria included the assumed values of internal and ex-ternal costs of product defects. The exploitation criteria comprised the required level of reliability or durability and the required value of prod-ucts repairability. The obtained results point to too high costs of lacks in technological criteria. The undertakings were proposed in order to de-crease them.
