Effectiveness assessment of agricultural machinery based on fuzzy sets theory

The main goal of this research was the development of an algorithm for the implementation of negative risk parameters in a synthesis model for a risk level assessment for a specific machine used in the mining industry. Fuzzy sets and fuzzy logic theory, in combination with statistical methods, were applied to analyze the time picture state of the observed machine. Fuzzy logic is presented through fuzzy proposition and a fuzzy composition module. Using these tools, the symmetric position of the fuzzy sets with regard to class was used, and the symmetric fuzzy inference approach was used in an outcome calculation. The main benefit of the proposed model is being able to use numerical and linguistic data in a risk assessment model. The proposed risk assessment model, using fuzzy logic conclusions and min–max composition, was used on a mobile crushing machine. The results indicated that the risk level of the mobile crushing machine was in the “high” category, which means that it is necessary to introduce maintenance policies based on this high risk. The proposed risk assessment model is useful for any engineering system.

“…Consequently, the crisp MCDM methods are extended into the fuzzy environment. The fuzzy MCDM methods are, therefore, widely employed across various areas of research (Kahraman, ; Kahraman and Kaya, ; Baležentienė and Klimas, ; Torlak et al ., ; Baležentienė and Kusta, ; Baležentienė and Užupis, , ; Miodragović et al ., ). The fuzzy logic does also enable to arrive at the linguistic reasoning, where assessments are expressed in words rather than numbers.…”

This paper focuses on the MULTIMOORA method. Specifically, it discusses its development as well as extensions alongside with an overview of their applications. Indeed, the MULTIMOORA is a relatively new multi-criteria decision making method consisting of the three parts. Therefore, it is specific with peculiarities of both complete and partial aggregation techniques. The MULTIMOORA method consists of the three parts, namely the Ratio System, the Reference Point, and the Full Multiplicative Form. The paper discussed the extensions of MULTIMOORA into the fuzzy environment and group decision making. The carried out survey identified the two major areas of application of MOORA and MULTIMOORA, namely engineering decision support for technological development and economic researches. The economic researches can further be classified into those related to micro-level or macro-level analyses.

The topic of pseudonymization of personal data has shown, that theoretical and methodological basics in sphere of automatized systems have just started to gain general trend. The majority of studies in this sphere are, commonly, about personal data in general, rarely touching the topic of pseudonymization and depersonalization. Therefore, the topic of pseudonymization has not fully assimilated in enterprise systems and has not grown any popularity, because enterprises tend to choose reliable tools and methods of information security while depersonalization is only beginning its way and is not common for big corporations. This leads to disinterestedness in solving known issues and goals of pseudonymization, universal methods have not been researched. However, low cost and simplicity of this method of personal data protection is turning our attention on it and ask ourselves a question: “Should we have a deep dive in it?”. Answer is obvious – yes. Certainly, this method has its disadvantages and it is not an ideal solution. But it certainly should be distributed worldwide.
