In the era of rapid technological development in the 21st century, which many experts refer to as the Fourth Industrial Revolution or Industry 4.0, artificial intelligence (AI) has received a new impetus for development and is increasingly integrated into our daily lives. This trend has become especially noticeable in the last few years. This article presents a novel approach to understanding and implementing AI technology, based on a "symbiotic alliance" between humans and machines. The article explores the concept of "symbiotic decision-making systems" (SDMS), which represent a new paradigm in decision-making. SDMS are grounded in the intersection and symbiosis of human and machine intelligence. The article introduces the definition of SDMS and proposes a classification system for them.
