在現在高度競爭的環境下，船舶製造商除了必須因應新船需求快速提升，在多艘新船製造並行下，限制的交船時間更是一大挑戰。面對這般變幻莫測的環境與多重限制，迫使造船公司決策者必須加強其造船製程效率。由這篇研究的建構模型所求出的最佳解，能夠協助決策者做出較適當的決策。近年來，經過金融風暴以及全球經濟蕭條之後，造船企業開始重視成本管理模擬以及成本控管。除此之外，在瞬息萬變的市場變化之下，匯率差也成為一個影響甚巨的因素，貨幣時間價值變得越來越重要；為了達成上述這些目標，學者們提出建議使用專案管理方法去達到這些要求。在此篇研究中，我們應用了模糊理論模型和現值成本法的概念來解決造船專案管理問題。此模糊理論模型目標是最小化總專案成本、總專案時間、以及趕工成本。除此之外，我們應用符號距離法去轉化模糊數，讓它轉成兩個極值，然後解模糊化，進而算出數值。另外，這篇論文會加入現實參數進入模型，來解決模糊多目標造船專案管理問題。這些最佳解將更貼近實際的情況。

In the highly competitive environment, shipbuilding enterprises have to cope with the rapidly increase demand of new ship, and the limited delivery time is a great challenge to naval architecture enterprises. Therefore, decision makers of naval architecture corporations are forced to reinforce their shipbuilding procedure. In this study, the proposed model is utilized to figure out optimal solution to help decision makers making decisions. In recent years, after global financial crisis and economic depression, naval architecture enterprises find it is significant to step up cost management practice, and improve the ability of cost control. Besides, exchange-rate difference is also a fatal influence factor in this constantly changing market; thus “time value of money”issue becomes more and more important. In order to achieve these goals, researchers introduce “Project Management” to meet the requirement. In this paper, a fuzzy model is established and the Net Present Value (NPV) method is applied for the multi-objective naval architecture project management problem. The fuzzy model tries to minimize total project cost, total completion time and total crashing cost in the same time. Besides, the signed distance method is utilized to the proposed model to transform fuzzy numbers into crisp values and a defuzzification model will be provided in this paper. Moreover, this paper will present an interactive solution procedure to get the preferred satisfactory solution for the multi-objective naval architecture project management. The solution in this paper are closer to approach the reality of the world.
