INTEGRATED TECHNIQUE SEARCHING CAUSES OF QUALITY INCOMPATIBILITIES

Abstract

Achieving the expectation quality products level is possible among others, by using adequate management techniques, which allow or identify incompatibilities, its sources, and above all, the reasons for its occurrence and ways of its elimination. Applying in this aim singe technique is common, but it was turned out that a lack is integrated connection between selected techniques. The purpose of the study is to propose a technique consisting of cyclical use: brainstorming (BM), relationship diagram, cause and effect diagram, multiple voting, and the AHP method.The technique was verified in the nondestructive testing process. The analysis was performed for often occurring incompatibilities in mechanical sealers for 410 steel. The identified incompatibilities of the analyzed mechanical sealers were the most frequent porosity, which was identified by fluorescent method (FPI). The effectiveness of the proposed technique was shown. The main advantage of its use was to improve the process of decision-making referred to incompatibility causes. It is possible to effectively use this method to analyze another type of incompatibility and products in production and service enterprises.
