Research On Effectiveness Evaluation Technology Of Anti-Submarine Helicopter Attack Submarine

Anti-submarine helicopters play a vital role as one of the primary weapons and equipment in submarine warfare,offering excellent maneuverability,a wide array of anti-submarine equipment,and high efficiency in combating submarines.While some progress has been made in researching the individual combat effectiveness of anti-submarine helicopters,there remains a scarcity of studies focused on systematically evaluating their overall combat effectiveness.Previous studies often separate the search effectiveness of anti-submarine helicopters from their torpedo attack capabilities,relying on subjective judgment of individual experts to establish evaluation models.This approach frequently leads to incomplete assessment content and inaccurate evaluation results.To address these limitations,this thesis aims to evaluate the attack effectiveness of anti-submarine helicopters by considering the helicopter platform and its mounted weapons as a unified system.A mathematical model for submarine warfare will be established,which incorporates multiple indices for group decision-making.Additionally,a software tool for evaluating the effectiveness of anti-submarine helicopter attacks against submarines will be developed.This software will enable the assessment of anti-submarine helicopter’s performance across various combat missions.The specific research objectives of this thesis are as follows:(1)Based on the analysis of the weapon and equipment performance of the antisubmarine helicopter and the process of attacking submarines,the attack model of the antisubmarine helicopter,the motion model of the anti-submarine helicopter and the submarine,and the search model of the anti-submarine helicopter were established.A multi-aircraft cooperative sonar search formation was studied for submarine targets without directional information,and a probability model for the anti-submarine helicopter search was established based on the probability of submarine distribution.This provides model support for the operational simulation of the anti-submarine helicopter effectiveness evaluation software.(2)According to the design principles of effectiveness evaluation indices,the attack submarine combat indices for anti-submarine helicopters are summarized.An evaluation index system for the attack submarine effectiveness of anti-submarine helicopters is established.The steps for evaluating the attack submarine effectiveness of anti-submarine helicopters are defined.An analysis of the improvement directions for the analytic hierarchy process and fuzzy analytic hierarchy process is conducted.An effectiveness evaluation method based on group decision-making and fuzzy analytic hierarchy process is proposed.A weight calculation model is established based on the least square principle,and the expert weight set is computed.This ensures that the index weights better reflect the opinions of the expert group and provides an evaluation method for the attack submarine effectiveness evaluation software of anti-submarine helicopters.(3)The anti-submarine helicopter attack and search effectiveness evaluation software was designed and implemented.The software is based on anti-submarine helicopter attack and search simulation,simulating different situations of anti-submarine helicopter attack and search under various missions.The simulation data is used as the quantitative indicator parameters for evaluating the anti-submarine helicopter attack and search effectiveness.Meanwhile,the software can dynamically adjust the subjective and qualitative parameters in the indicators.The anti-submarine helicopter attack and search effectiveness is evaluated using a combination of qualitative and quantitative parameters,and the evaluation results are displayed and analyzed.
