The process of ship form evaluate alternatives is a multiple criteria and multiple objectives one , which is mainly based on the designers " subjective experience in the past . the bias error is inevitable because the result mainly depends on the designers " subjectivity 船型方案论证是一个多准则、多目标的决策过程，过去主要靠设计者的经验来完成，船舶工程系统设计基本上还是一种经验设计，这使得最终的决策结果难免带有由于决策者的主观臆断性而可能造成的系统误差。
Abstract : take cylindrical compression string which has been applied extensively in the piston compressor with the concentric ring valve for example , the mathematics model of optimum design for the air valve string has been set and the optimum value of single & multiobjective has been evaluated by the way of monotonic analysis 文摘:以活塞式压缩机环状阀中使用最为广泛的圆柱形压缩弹簧为例，建立了气阀弹簧优化设计的数学模型，并用单调分析法进行了单目标和多目标的优化求解
A novel strategy combined the fuzzy logic of linear multivariable feedback control to design a controller of statcom to meet the multi - objective demands of power systems is also proposed in this dissertation , and the controller is designed with this strategy , because of variational element , nonlinearity and multi - objective controlling demands of statcom , this paper designs the controller respectively aimed at continuous linear control for voltage maintaining , oscillation damping , improving the transient stability 根据电力系统变参数、非线性以及对控制要求多目标的特点，本文针对维持系统节点电压、阻尼系统振荡、提高系统暂态稳定性能等不同控制目标分别设计了控制器，然后将模糊逻辑和多状态线性反馈相结合，提出了一种能满足电力系统多目标要求的控制方法，并用该控制方法为statcom设计了控制器。
