The article consideres the problems of determining the need to modernize the base stations of the cellular network based on the mathematical apparatus of the theory of fuzzy sets. To improve the quality of telecommunications services the operators should send significant funding for upgrading the equipment of base stations. Modernization can improve and extend the functions of base stations to provide cellular communication, increase the reliability of the base station in operation and the functionality of its individual elements, and reduce the cost of maintenance and repair when working on a cellular network. The complexity in collecting information about the equipment condition is determined by a large number of factors that affect its operation, as well as the imperfection of obtaining and processing the information received. For a comprehensive assessment of the need for modernization, it is necessary to take into account a number of indicators. In the structure of indicators of the need for modernization, there were introduced the parameters reflecting both the degree of aging and obsolescence(the technical gap and the backlog in connection with the emergence of new technologies and standards). In the process of a problem solving, the basic stages of decision-making on modernization have been allocated. Decision-making on the need for modernization is based not only on measuring information that takes into account the decision-makers, but also on linguistic and verbal information. Therefore, to determine the need for upgrading the base stations, the theory of fuzzy sets is used, with the help of which experts can be attracted to this issue. They will be able to formulate additional fuzzy judgments that help to take into account not only measuring characteristics, but also poorly formalized fuzzy information. To do this, the main indicators of the modernization need have been defined, and fuzzy estimates of the need for modernization for all indicators and a set of indicators reflecting the need for upgrading the base stations have been formulated.

AbstractWe discuss a potential case of borrowing in this paper: Breton a- ‘of’, ‘from’ marking of (internal) verbal arguments, unique in Insular Celtic languages, and reminiscent of Gallo-Romance de/du- (and en-) arguments. Looking at potential Gallo-Romance parallels of three Middle Breton constructions analyzed in some detail (a with indefinite mass nominals in direct object position, a-marking of internal arguments under the scope of negation, a [allomorphs an(ez)-/ahan-] with personal pronouns for internal arguments, subjects (mainly of predicative constructions) and as expletive subjects of existential constructions), we demonstrate that even if there are some semantic parallels and one strong structural overlap (a and de under the scope of negation), the amount of divergences in morphology, syntax and semantics and the only partially fitting relative chronology of the different constructions do not allow to conclude with certainty that language-contact is an explanation of the Breton facts, which might have come into being also because of internal change (bound to restructuring of the pronominal system in Breton). More research is necessary to complete our knowledge of a-marking in Middle Breton and Modern Breton varieties and on the precise history of French en, in order to decide for one or the other explanation.
