Aiming at the current evaluation methods of technical contribution rate are mostly based on static combat networks with low credibility of the evaluation results,an evaluation method of technical contribution rate of U.S. aircraft carrier combat system-of-systems considering the influence of time and space is proposed.The U.S. aircraft carrier combat network model considering time and space factors is constructed based on OODA (observation,orientation,decision,action) operation loop.The effectiveness evaluation method of combat system-of-systems based on self-information is proposed. Combining the degree of technical support for equipment combat technical indicators, an evaluation model of technical contribution rate is established.Taking the air defense and anti-missile combat system-of-systems of the U.S. aircraft carrier as an example,the results show that the proposed method fully takes into account the spatial-temporal dynamic characteristics of the combat network,which can assess the contribution rate of technology more realistically and objectively,and support for the equipment project approval demonstration and technology optimization development.

Aiming at the demonstration and evaluation characteristics of systematic reliability,maintainability and supportability (RMS) requirements on complex equipment systems,through the research on RMS requirements, capability analysis, architecture analysis,simulation and evaluation of equipment system, the procedures and techniques for demonstrating and evaluating the RMS requirements of complex equipment systems are proposed. The idea of software platform architecture based on the above technology is given, which provides ideas and methods for carrying out the demonstration and evaluation of the RMS requirements of the complex equipment system that emphasizes systemization and actualization.

Radar measurement error is a main factor affecting the hand over precision during terminal guidance of the air defense missile weapon system, and the method to synthesize and evaluate the error is the key point in the weapon system research. Pointing at the common methods of error synthesis, the statistical results of each error synthesis method are analyzed, and the applicability of each error synthesis methods is studied. The radar flight calibration data are used for verification, which can be taken as the basis of the weapon system precision chain design.
