隨著顧客的消費能力大幅提昇，以往單一產品已不能滿足今日消費者多變的需求，企業為增加本身的競爭能力，必須提供多樣化的產品以滿足不同消費族群的需求，產品的多樣化設計（Product Design for Variety）將成為企業製造與生產時，需要考慮的問題。在近幾年來，企業漸漸發現大規模生產製造模式，雖然可以降低生產成本，但是單一的產品樣式，較難吸引消費者的目光，今日的消費者要的是符合其要求的產品。因此，企業開始將模組化(Modular)的概念應用在產品設計上，透過功能模組的搭配變換，可以滿足不同消費者的需求，並且可使企業在開發產品時做出快速且正確的反應，以符合市場的需求。然而模組零件越多，設計上將更為複雜，企業若能在諸多模組當中，選擇最適當的模組來進行生產，節省不必要的成本損失，將使企業增加額外的利潤，也將使企業競爭力大幅提升。因此，本研究以模組化的結構為基礎，訂定一個利潤函數，並結合遺傳演算法找到最適模組零件來進行多樣化產品的製造。

When the consumption is increasing rapidly, the simplex products have not satisfied with the demand of customers. Manufacturers attempt to increase their ability of competition. They must provide varied products to satisfy with the demand of customers. When manufacturers fabricate products, product design for variety will be considered. During the several years, manufacturers detect that the cost can be decreased by a lot of production, but the customers are attracted hardly by the simplex form of product. The customers desire to conform to their requirements. Manufacturers begin to apply modular conception in product design. Through the function modules compose, it will satisfy with the different groups of customers and manufacturers will make a decision rapidly and correctly in product design. But when quantities of modules are increasing, it will be complex in product design. If modules can be chosen optimally and produced by the manufacturers, the cost will decrease and the competition ability of manufacturers will rise rapidly. This paper bases the module conception to construct a model and describes the genetic algorithm is applied to search the optimal combination of the modules. The manufacturers will fabricate products by the optimal modules.
