Abstract
This article considers the problem of increasing the efficiency of operational management of an oil refinery in the event of complex emergency situations that require immediate response, strict coordination 247of actions and damage minimization. The relevance of the work is due to the high degree of risk in the management of technological processes in the petrochemical industry, where failures and accidents can have critical consequences for both the production cycle and the environment.A methodological approach based on the use of piecewise linear approximation is proposed, which allows simplifying the integral form of the control problem by switching to a discrete model that ensures fast and accurate calculation of optimal strategies. Definitions of metrics of the distance between the states of the object, as well as the damage function, taking into account the importance of various parameters of the technological system through weighting factors, are introduced. Dynamic programming is used as an optimization method, providing a step-by-step selection of the best trajectory for eliminating an emergency situation.The transition conditions are formalized, models of admissible trajectories are developed taking into account the restrictions. The proposed method was tested using a real production incident as an example, which allowed us to confirm the accuracy and sustainability of the proposed approach in practice. The results obtained can be used in developing automated safety management systems at industrial enterprises in the oil refining industry
