IMPROVEMENT OF A PRODUCT DESIGN USING MULTI CRITERIA DECISION MAKING METHODS WITH TAGUCHI METHOD

16580

Producing a high quality product is very important in satisfying customer needs and gaining customer confidence. Not being able to provide customers a high quality product eventually results in decrease of profits for manufacturing companies. Therefore, this situation is extremely important in survival of manufacturing companies in ever increasing competition generated by not only domestic but also international companies. To produce high-quality products, the factors that may affect product quality, should be analyzed starting with the product design stage. In this study, first, the factors that are important in quality of a washing machine and their levels are determined. Then, these factors and their interactions are analyzed using an experimental design model developed in the study. Finally the optimal levels of the factors are determined with the solution of the model. In the study, along with the Taguchi method, the Multi Criteria Decision Making (MCDM) methods such as; GRA (Grey Relational Analysis), TOPSIS (Technique for Order Preference by Similarity to Ideal Solution), and VIKOR (Vlse Kriterijumska Optimizacija I Kompromisno Resenje- Multi-Criteria Optimization And Compromise Solution) are also used in the development of the model and its solution. The results of the different approaches are compared and the optimal factor-level combinations are determined.
