  4. For long time, the theory of the criteria system of the evaluation of torpedo collectivity design scenario lacked systemic discusses

    長期以來，有關魚雷總體方案評估指標體系的理論研究都比較零散和片面，特別缺乏系統有序的闡述。
  5. In order to solve two difficulties in the present conceptual design of torpedo, this paper introduces many new ideas into the original theories, and gives a new synthetic conceptual design theory for torpedo. one of the difficulties is that we have no a index which can represent various performances of torpedo, the other is that the coupling relationships among various subsystems and disciplines are ignored in the design process. the new ideas involve the study about operational effectiveness, life circle cost, risk and research schedule, which can be used together to evaluate a design project

    本文針對魚雷總體設計中目前存在的兩個突出技術難題： （ 1 ）缺乏能夠全面反映魚雷總體設計性能的指標（ 2 ）對魚雷總體設計中各部分組成、各學科間的耦合關系，沒有合適的分析和求解方法在原魚雷總體設計理論和方法的基礎上，引進了作戰效能、壽命周期費用、風險和研製周期的概念，來全面反映魚雷設計的性能、經濟性、風險性和時間性等指標；在優化設計中，採用多學科設計優化方法作為優化演算法，構建了一種新的魚雷總體綜合設計方法。
  6. ( 3 ) in the new theory of synthetic conceptual design of torpedo, this paper takes operational effectiveness as the object function in the optimization model. models and analysis methods are given for the synthetic conceptual design of torpedo based on the operational effectiveness. in order to involve economic index in the study, this paper introduces life circle cost into the synthetic conceptual design, and gives a model of design based on the ratio of cost and effectiveness
