Problems solved by technology

This method is mainly configured according to the functional positioning and coverage capabilities of various types of aircraft. It does not comprehensively consider the synergy and utilization of the overlapping coverage of each aircraft type, and does not consider the characteristics of the regulatory waters, which makes it difficult for the configuration scheme to effectively play the role of aircraft.

Abstract

The invention provides a seaborne supervision and rescue aircraft service efficiency evaluation method, which comprises the steps of determining an adaptive evaluation water area and an evaluation water area area, and further comprises the following steps of: calculating a supervision effective coverage rate PWD of the evaluation water area considering a risk weight, a supervision coverage utilization rate PAi of each aircraft in the evaluation water area and a supervision coverage intensity PC of the evaluation water area; index thresholds are determined, wherein the index thresholds comprise a supervision effective coverage rate threshold lambda1, a supervision coverage utilization rate threshold lambda2 and a supervision coverage intensity threshold lambda3; comparing the PWD with the lambda 1, and judging whether the effective coverage rate of the water area supervision rescue aircraft is qualified or not; comparing the PAi with the lambda2, and judging whether the utilization rate of each airplane is qualified or not; comparing the PC with the lambda3, and judging whether the water area aircraft layout is reasonable or not. The method can effectively guide the quantitative evaluation and optimization of the configuration scheme efficiency of the supervision rescue aircraft, and the quantitative comparison and selection of the construction scheme of the supervision rescue aircraft and the multi-aircraft cooperative search and rescue scheme, and provides reference for the configuration efficiency and scheme optimization of related equipment.

Description

technical field [0001] The invention relates to the technical field of rescue aircraft performance evaluation, in particular to a service performance evaluation method for maritime supervision and rescue aircraft. Background technique [0002] Maritime supervision and rescue aircraft, as a general term for the "air" link in the "land, sea, air and space" integrated water transportation security system, include manned fixed-wing aircraft, rescue helicopters, and fixed-wing and rotary-wing multi-type UAVs. It is used for maritime patrol, emergency search and rescue and life rescue. In the future, the development of water traffic safety will change from the pursuit of speed and scale to more emphasis on quality and efficiency. It is urgent to understand the service efficiency of the configuration of supervision and rescue equipment, so as to optimize and adjust the construction layout and configuration intensity of construction projects in a timely manner. At present, the conf...
