Optimization tasks in many technological processes are inherently multidimensional and often characterized by uncertainty and fuzziness. This study focuses on the development and application of a method for solving multi-criteria optimization problems under such fuzzy conditions, using the delayed coking process as a case study. Main Results: A heuristic method has been developed by combining and modifying the principles of the main criterion and ideal points to address multi-criteria optimization in a fuzzy environment. Traditional methods for solving fuzzy optimization problems typically involve converting the initial fuzzy problem into a series of crisp (deterministic) problems using level sets. Scientific Novelty: The novelty of the proposed heuristic approach lies in its ability to formalize fuzziness and solve the original problem directly in the fuzzy domain, without transforming it into a set of crisp sub-problems. This leads to more accurate and practically applicable solutions in fuzzy environments. Practical Value: The proposed method can be effectively applied to optimize the operational parameters of complex industrial processes where uncertainty is a significant factor. Results: The optimization results for the delayed coking process demonstrate the advantages of the proposed fuzzy approach compared to traditional methods. This multi-criteria fuzzy optimization method enables more effective decision-making by leveraging available fuzzy information to its fullest extent.
