分析了外国空军重视效费比研究的原因和采取的几项措施。对发展武器系统应进行科学论证,选择武器系统应进行综合对比,武器系统的使用要求应力求合理、高效和延长使用寿命等方面进行了论述。最后希望在发展武器装备时应对效费比的研究予以重视并加大力度。 Analyzes the reason why the foreign air force attaches importance to the research on the cost-effectiveness ratio and several measures to be taken. The development of weapons systems should be scientifically justified, the selection of weapons systems should be comprehensive comparison, the use of weapons systems should be reasonable, efficient and extend the service life and other aspects are discussed. Finally, I hope we should pay more attention to and intensify the research on the cost-effectiveness ratio when developing weapons and equipment.
