Abstract:
This study developed models to solve problems of optimisation, production, and
consumption in waste management based on methods of system analysis. Mathematical models of
the problems of optimisation and sustainable waste management in deterministic conditions and in
a fuzzy environment were formulated. The income from production was maximised considering
environmental standards that apply to the field of macroeconomics and microeconomics. The proposed
approach used MANAGER software to formalise and solve the problem of revenue optimisation with
production waste management to optimise the production of oil products with waste management
at a specific technological facility of the Atyrau oil refinery in Kazakhstan. Based on the combined
application of the principles of maximin and Pareto optimality, a formulation of the problem of
production optimisation with waste management was obtained and a heuristic algorithm for solving
the formulated fuzzy optimisation problem with waste management was developed.
