This paper is based on the cosco vessel investment decision support system project. firstly, according to the shipping enterprise ' s situation and character, a program suitable to the shipping enterprise is given, which is used to help decision - maker analyze the economical effect of the investment and choose correct investment project. secondly, the author extends the use of the evaluation method of single ship investment, simplifys the calculation of revenue and cost, set up the multi - objective synthesis evaluation model of ship investment to evaluate ship investment considering the fleet as a whole, then to make decisions on vessel type jtonnage, number, financing pattern ; finally, the author analyzes the system, and designs the system, mainly including the design of operation database, design of decision support database, the design of models database, system interface, the style of the system, and analyzes the techni cal problems about the system, some functions has been put into use
以輔助或支持企業的決策者分析投資的經濟效果，選擇投資方向及決策方案，使決策的結果更能滿足航運企業發展的實際需要，作出科學的決策；其次，本文將單船投資決策的技術經濟評價方法進行推廣，在計算npv指標中涉及到的復雜的成本與收入計算問題進行簡化，並利用運籌學的知識，建立船舶投資決策模型，從船隊整體角度對船舶投資進行綜合評價，以達到對船隊中投入船舶種類、船舶噸位、數量與融資方式選擇的多維決策；最後，本文對船舶投資決策支持系統進行了詳細的系統分析，作出整體框架設計，主要包括操作數據庫設計、 dss數據庫設計、模型庫設計和系統介面、系統風格設計，並對系統開發中涉及到的技術問題予以分析，並實現了部分功能。 -
Obviously, the artificial ground motions used for structural time history analysis should well coincide with multi - damping - ratio - spectra. based on the comparison of the conventional algorithms for multi - objective optimization and genetic algorithms, a method for the simulation of multi - damping - ratio - spectra is proposed in the thesis which combines the multi - objective optimization algorithms and genetic algorithms. the program corresponding to the method is also developed and the method is proved to be feasible and convenient by an example at the end of the thesis
本文通過分析多目標優化問題的解的意義和常用解法，在比較現有的幾種常用優化演算法的基礎上，選用遺傳演算法這種自適應全局優化概率搜尋演算法作為本文的搜尋方法，將其與多目標優化理論有機地結合在一起，形成多目標遺傳演算法，並將其引入地震動模擬，形成基於遺傳演算法擬合多阻尼比反應譜的地震動模擬程序。
