Architecture of Computing with Words Based Information Technology for Proactive Aviation Security Control

Level of aviation security (AS) of an airport depends on the state of the system for countering acts of unlawful interference by intruders into airports (SCAUI), which includes airport security officers, as well as and technical devices for inspection of passengers, hand luggage, and baggage, security systems to protect the airport's controlled areas. In this article, we introduce basic principles of the information technology (IT), whose application allows to increase the airport AS by improving the quality of proactive control over the state of SCAUI. The developed IT is built on the basis of the client-server architecture and the SCAUI model. The authors propose to perform proactive control by consecutively solving direct and inverse problems. The direct problem is a problem of assessing the overall level of the AS based on the verbal assessments of individual factors. The inverse problem is the problem of identifying those factors, which have predominant influence on the AS. At the core of the SCAUI model and all computing involved in solving both direct an inverse problems lie ideas from the computing with words domain. Each word is represented as an interval type-2 fuzzy set, and their aggregation is performed using linguistic weighted average.
