Abstract:
Statements of decision-making problems for managing fuzzy
technological objects have been formalized and obtained. and methods for
solving them are proposed. The object of study is a heating station for a
“hot” main oil pipeline. Since such objects are often characterized by multicriteria and often operate in conditions of unclear initial information, the
tasks are formalized in the form of multi-criteria decision-making problems
in a fuzzy environment. Based on the modification of various optimality
principles, new mathematical formulations of the problems to be solved
were obtained and interactive heuristic algorithms for solving them were
developed. The novelty of the proposed approaches to solving formalized
fuzzy problems from well-known methods for solving fuzzy problems lies
in the fact that problems are posed and solved without first converting them
to equivalent deterministic options, which does not reduce the loss of
original fuzzy information and makes it possible to obtain more adequate
and effective solutions. An example is given of the practical application of
the proposed approach to solving decision-making problems by
implementing one of the developed algorithms when solving the problem of
choosing an effective operating mode for the oil heating station of the UzenSamara oil pipeline at the Atyrau point.
