Search and rescue (SAR) is an important part of joint operations, and also one of the key supports for
ensuring combat eectiveness. Aviation equipment is a major component of SAR action. Therefore,
the SAR capability of aviation equipment has become the key to aecting the overall SAR action.
This paper proposes the concept of the system of systems inuence degree (SoSID) and conducts a
scientic quantitative evaluation to quantitatively measure the eect of aviation equipment used in
SAR. First, according to the characteristics of SAR action in threat environments, the SAR capability
of aviation equipment is analyzed, and an indicator decomposition hierarchy model based on this
SAR capability is proposed. Second, based on the above model, the DECIDE (destroy, execute, cost,
implement, defend, evade) SoSID evaluation model is proposed. Third, a comparative test is designed
and a sensitivity analysis is conducted based on the sobol power sensitivity (SPS) analysis method
to obtain the index sensitivity of the SAR capability. The sensitivity is then ranked to obtain key
indicators. Finally, we build a simulation test environment to obtain multiple test plans for comparison
and verify the rationality of the index decomposition hierarchy model and the SoSID evaluation model
as well as the eectiveness of the SPS analysis method through analysis of the simulation results.
In modern high-tech wars and local conicts, the search and rescue (SAR) for people in distress on one’s side not
only acts to save an individual life but also oen develops into severe military and political events. erefore, it
is of great signicance to successfully conduct SAR actions to improve the operation capability of the joint force.
SAR mainly consists of SAR teams, including helicopters, attack aircra and refueling aircra, radar satellites
and other auxiliary forces, including mission control and rescue coordination. Aviation equipment system SAR
teams have been the key force for a SAR action.
erefore, this paper places aviation equipment into a SAR mission, through simulation test environment
and analyzing the simulation data to calculate the inuence degree of each piece of aviation equipment and its
performance on the SAR action, so as to provide a theoretical reference for the design of aviation equipment
and decision support for the commanders faced with actual SAR mission.
A common approach to measuring the degree of the inuence of aviation equipment on the system of systems
(SoS) state is to introduce the concept of SoS contribution, which examines the contribution degree of changes
of the equipment to be evaluated to the eectiveness of the operation SoS. Measurement of the SoS contribu-
tion of equipment, based on a review of the current domestic and international studies, is mainly based on the
perspectives of the SoS mission eectiveness and the SoS requirement satisfactory degree, which mainly includes
the contributions of weapon and equipment to the combat mission accomplishment eect
