Sustainable management issues of waste during drilling oil wells in marine conditions,
the process of disposal of drill cuttings in the conditions of deficiency, and fuzzy initial information
using fuzzy inference system are investigated. Based on the conducted system analysis, the main
criteria for controlling the process of re-injection of suspended drill cuttings were analyzed and
selected. We described the technology of preparation and injection of drill cuttings slurry into the
underground horizon. The method of modeling and management of the process of disposal of drilling
cuttings in the marine environment in a fuzzy environment with the use of fuzzy inference system,
which helps to overcome the problems of scarcity and fuzziness of the original information due to
the knowledge and experience of experts are proposed. The scheme and structure of the elements
of the fuzzy inference system based on the Mamdani algorithm are given. The implementation of
the fuzzy output system procedure was carried out in MatLab using Fuzzy Logic Toolbox. For the
purpose of sustainable waste management in the process of oil production of marine fields, waste
management tasks are formulated as a fuzzy mathematical programming problem, which takes into
account economic and environmental criteria and many production constraints that may be fuzzy.
Since the vector of such criteria is characterized by inconsistency, the developed methods for solving
the set tasks of sustainable management are based on various tradeoff schemes modified to work
in a fuzzy environment. The novelty and originality of the developed methods lies in the fact that,
unlike the well-known methods of similar methods for solving fuzzy problems, they are set and
solved without conversion to a system of equivalent deterministic problems, with-out losing the
main part of the collected fuzzy information. This allows, through the full use of the original fuzzy
information, to obtain a more adequate solution to the fuzzy problem of the real problem under
production conditions.
