This paper addresses an application of the specific methods of multi-criteria decision analysis to specify the appropriate supplier of an autonomous train in a certain production–distribution company. This company identifies three potential suppliers dealing with the development and purchase of autonomous train systems. In terms of the multi-criteria decision analysis, the WSA method, the Scoring method and the TOPSIS method were used to define a suitable compromise solution. To apply each method, individual suppliers were sorted depending on the appropriateness for the examined company based on relevance with all the identified criteria and their weights. The evaluation criteria include procurement cost, time of the whole autonomous train system project implementation, references from plants where such a technology has already been introduced, service department availability and battery charge time. Thereafter, the outcomes obtained using individual methods were compared to each other and the compromise supplier of the autonomous train system to be implemented in the selected company was determined.

Site selection is one of the basic vital decisions in the start-up process, expansion or relocation of businesses of all kinds. Construction of a new industrial system in the form of solar photovoltaic power plant is a major long-term investment, and in this sense determining the location is critical point on the road to success or failure of industrial system. One of the main objectives in industrial site selection is finding the most appropriate site with desired conditions defined by the selection criteria. This work suggests how to define and classify particular criteria considered for solar PV farm siting. Multi-criteria decision analysis (MCDA) is proposed as a method to process available technical information to support decisions in many fields, especially in environmental decision making. In some cases, due to the lack of reliable information on the impact of various natural factors on the economic activity related to the use of land resources, the method of expert assessments can be used. The peculiarity of this method is the lack of empirical evidence of the influence of a given factor on the final result of decision-making. In this case the value of separate factor is judged by experts. When applying this method, expert groups are formed of leading specialists, the main influence factors is established, a questionnaire and a scale of criteria are compiled. Level of reliability of the results is assessed by the coefficient of concordance.
