Search and Rescue at Sea: Situational Factors Analysis and Similarity Measure

Search and Rescue at sea (SAR) is an important guarantee of maritime security. The similarity among search and rescue situations is the vital basis of generating instant search and rescue plan. On the basis of the process of maritime search and rescue, the influential factors of SAR situation are analyzed. Through establishing search and rescue sequence, a similarity measure model of maritime search and rescue situation is proposed based on concept lattice. Example analysis is involved.
