and multidisciplinary design optimization ( mdo ), a new theory about complex engineering system design, is chosen as the optimization method for such a large engineering system . the main points in this paper are as follows : ( 1 ) based on the system effectiveness model from wseiac, this paper studies the corresponding factors of torpedo weapon system, and gives both its model and analysis architecture . every effectiveness index is studied and given corresponding ways of analysis 本文的主要研究?jī)?nèi)容和成果如下:(1)運(yùn)用wseiac模型,結(jié)合魚雷武器系統(tǒng)的作戰(zhàn)過程和武器系統(tǒng)組成的具體實(shí)際,給出了魚雷武器系統(tǒng)作戰(zhàn)效能的數(shù)學(xué)模型,構(gòu)造了作戰(zhàn)效能分析的指標(biāo)體系,并對(duì)各個(gè)作戰(zhàn)效能指標(biāo)進(jìn)行了詳細(xì)的分析和討論,給出了相應(yīng)的分析和研究方法;綜合應(yīng)用模糊數(shù)學(xué)和灰色理論,提出了兩種用于作戰(zhàn)效能評(píng)判的灰色模糊綜合評(píng)判方法;為了考慮作戰(zhàn)過程中的不確定因素,設(shè)計(jì)了一種作戰(zhàn)效能的仿真方法。
