What are the theories of search and rescue?

Theories of search and rescue (SAR) primarily focus on optimizing the efficiency and effectiveness of locating and assisting individuals in distress. Key theories include the "Area of Probability" model, which estimates where a missing person is likely to be based on last known positions and environmental factors. Another approach is the "Search Pattern Theory," which involves systematic methods, like grid or sector searches, to cover areas thoroughly. Additionally, advancements in technology and data analysis have led to theories that incorporate predictive modeling and real-time information to enhance SAR operations.
