Description: The assessment technique in the conditions of fuzzy non-stochastic uncertainty of the advisability of manufacturing the perspective product on the advantages of the influence of myriad of qualitative nature factors is proposed. The formalized description of the myriad of qualitative nature factors seems to be an introduction to the consideration of the linguistic function of the myriad of linguistic variables. The fuzzy myriad for which the membership function is formed corresponds to each fuzzy number as the value of each linguistic variable that make up the myriad. The myriad of linguistic variables corresponds to myriad of some dimension of the qualitative nature factors, which, according to the understanding of the decision maker, he introduces them for consideration depending on the natural purpose of the perspective product. The subset of linguistic variables that corresponds to the accepted level of non-dominance of the decision maker is the function of belonging to the core of the fuzzy relation of strict preference, the qualitative nature factors, constitutes the myriad of the variables of the linguistic function of the myriad of linguistic variables. The essence of the functional dependence of the linguistic variables that determine the linguistic function is determined by the decision maker on the basis of known arithmetic operations and an understanding of the content of requirements for a prospective product. The formed functional dependence of the linguistic function of linguistic variables is used as the basis for determining the content of the list of alternatives for making a decision on the feasibility of manufacturing a prospective product sample. The comparison of the essence of the function of belonging to the linguistic function of the myriad of linguistic variables that correspond to different alternatives allows the decision maker to make a decision as to the appropriateness of the alternative, depending on the content and size of its resources.


Keywords: fuzzy non-stochastic uncertainty, qualitative nature factors, linguistic function of the myriad of linguistic variables, membership function
