Využití vybraných matematických a statistických metod k vyhodnocování dat spjatých s oblastí kvality

Abstract

The object of this thesis was to systematize the approaches of the selected mathematical and statistical methods, namely the use of fuzzy logic for selected methods. These methods include QFD and FMEA, their description and applications in the field of quality. The first part of this thesis describes the fuzzy logic. This part explains its basic definition and processing. The next part deals with method FMEA (Failure Mode and Effects Analysis). We can find the description of traditional method FMEA and its other innovative approaches here. The third section provides a principle and overview of the application and development of QFD (Quality Function Deployment), "house of quality" in the Czech sense. The last part contains the application of the methods QFD and FMEA using fuzzy logic in specific example.
