Abstract
Excavators are quite expensive vehicles. Therefore, there may be huge losses for decision makers if a wrong decision is made during the purchasing process. A good evaluation of excavator alternatives both reduces costs and increases the benefits the excavator for the purchaser. The aim of this study is to prioritise excavator technologies to help decision makers during the purchasing process and to apply three different “data fusion methods” instead of the “theory of dominance” of the original MULTI MOORA method. The MULTI MOORA method is composed of three methods, namely: the ratio analysis as a part of MOORA, Reference Point Theory (the reference point approach as a part of MOORA) and the Full Multiplicative Form. It is used to prioritise excavator technologies in this study. The MULTI - MOORA method combines three results obtained from these three methods using the theory of dominance. Dominance directed graph, Rank position method and Borda count method as data fusion methods are also used to combine these three results instead of the “theory of dominance”. The results from this study show that there is no difference between the data fusion methods and the MULTI MOORA method can be applied to technology evaluation of the excavator alternatives successfully.

The MULTIMOORA method combines three results obtained from these three methods using the theory of dominance
Based on this matrix as an input, the ranking of the 13 excavator technologies according to the two parts of MOORA, namely, the ratio analysis and the reference point approach, and the full multiplicative form are performed
Summary
Machinery and equipment selection is essential to firms in order to be successful in a business environment. The selection of unsuitable machinery negatively affects all aspects of business performance This leads to failure in meeting the requirements of the customers in terms of quality, time and cost. The process of buying a machine is complex and consists of many stages In this process, different business managers try to determine the machine which will be bought with respect to certain criteria and to influence the selection decision based on their own selection priorities. Different business managers try to determine the machine which will be bought with respect to certain criteria and to influence the selection decision based on their own selection priorities They consider different evaluation criteria with respect to whether they are buying a machine for the first time
