Interactive algorithm for multi-criteria control of the catalytic reforming unit at the Atyrau oil refinery based on qualitative information

The paper addresses the problem of decision-making for optimal control of the technological complex of a catalytic reforming unit under conditions of multicriteria and uncertainty caused by the fuzzy nature of the initial information. It is shown that traditional deterministic optimization methods do not fully account...

A hybrid classification model for high-precision fault mode detection in three-phase electrical networks

In modern electric power systems, accurately identifying short-circuit conditions is essential for reliable network monitoring and protection. This study proposes a hybrid machine learning framework for multi-class fault mode classification in three-phase electric networks. The experimental dataset included 15 operatin...

A Heuristic Multi-Criteria Optimization Method for Controlling the Benzene Production Process in a Fuzzy Environment

In practice, benzene production is carried out in complex technological facilities such as Benzene Production Units (BPUs). These units include several interconnected subsystems of oil refineries, characterized by several interacting operational parameters that affect both the production volume and the quality indicato...
