Abstract:

This bachelor thesis deals with the selection of a rock polishing machine for the Yakutian Art School. The school currently has rock polishing machines that do not fit the current requirements because they are dated and old. In the beginning of the theoretical part of this thesis, the issue of the decision-making process will be outlined. The model of multiple criteria decision analysis (MCDA) will be described and its elements will be specified. This section explains the method of determining the weights of the criteria and the method for selecting a suitable, efficient alternative using multiple criteria decision-making (MCDM). The practical part of this thesis presents the decision-making problem the Yakutian Art School faces and its specifics. All following elements of this model are specified and described. The pairwise comparison method of Saaty is used to determine criteria weight through the preferences of the decision maker of this process. After the modelling, the concept of dominance is used to reduce the set of alternatives. The calculation leads to the selection of an efficient alternative which is done through a weighted sum approach. Based on all calculations, the option with the greatest utility for the Art School is selected and recommended to the Yakutian Art School. Finally, a sensitivity analysis is performed to test the ordering of alternatives based on the change of the price criterion. The price of one of the alternatives changes when given a discount from the seller and it is considered prior to the final solution of this thesis.
