Abstract:Magistrska naloga obravnava vrednotenje in izbiro tehnoloških rešitev za izdelavo statorjev elektromotorja. Izbrano podjetje, s katerim smo sodelovali pri izdelavi magistrske naloge, se vse pogosteje sooča z izbiro tehnoloških rešitev za izdelavo elektromotorjev in njihovih podsestavov. Zato smo se odločili za snovanje odločitvenega modela, ki bo omogočal hitro in enostavno vrednotenje tehnoloških rešitev za izdelavo statorjev. V magistrski nalogi smo predstavili razvoj in delovanje odločitvenih modelov po kombinirani odločitveni metodi utežene vsote in odločitvenih dreves ter odločitveni metodi DEX. V nadaljavanju smo analizirali alternative, odločitvene modele in rezultate primerjali in ugotavljali njihovo skladnost. Odločitveni modeli po obeh metodah pomagajo ovrednotiti najboljšo tehnološko rešitev na nivoju dobavitelja tehnološke rešitve za izdelavo statorjev. V modelu, izdelanem po kombinirani metodi utežene vsote in odločitvenih dreves, smo upoštevali tudi verjetnost pojavitve napovedanih proizvodnih količin, s čimer smo poskusili izbiro še dodatno izboljšati in čim bolj zmanjšati odločitveno tveganje. Zaradi kompleksnosti odločitvenega problema smo odločanje pri obeh odločitvenih modelih razdelili na dve stopnji in tako dosegli boljšo strukturiranost in preglednost odločitvenega postopka. Iz obeh odločitvenih modelov smo dobili enako razvrstitev izbranih alternativ in tako ugotovili, da sta modela primerljiva. Najbolje ovrednoteni dobavitelj strojne opreme je z Japonske in se tudi v realnosti izkazuje kot najboljši izmed treh ponudnikov strojne opreme za izdelavo statorjev elektromotorjev. Iz tega lahko sklepamo, da sta odločitvena modela pravilna in primerna za realizacijo v praksi.

Title:Assessment and selection of technical solutions for stator production
Abstract:The master thesis is about evaluation and selection of technological solutions for the production of stators for electro motors. The company we have collaborated with in making this master thesis is frequently faced with choosing technological solutions for producing electro motors and their sub components. Confronted with this issue, we decided to design a decision model, which will allow a quick and simple evaluation of stator production technological solutions. In the thesis we are presenting the designing and the concept of decision models, using two methods: a combination of a weighted-sum method and decision trees, and the method DEX. We analized decision alternatives, compared decision models and results, and evaluated their compliance. From both decision models we got the most suitable technological solution for stator production on the equipment supplier level. In the combined weighted sum and decision tree model of we considered also the probability of occurrence for different forecasted production quantities scenarios. With this we tried to further improve the selection and reduce the decision risks. Because of the complexity of the decision problem we carried out the evaluation in two stages. This allowed us to achieve a better comprehensibility and structure of decision models. We got the same results from both decision models and the same classification of the alternatives, so we could conclude that the decision models are comparable. The best evaluated machine supplier for stator production technology is also in the reality performing the best of the three evaluated suppliers. From this we can conclude that the decision models are correct and suitable for implementation in practice.
