依據自己所需的系統功能，量身訂做一套完全屬於自己的軟體，是軟體界的一個夢想。為了達到這個夢想，許多人致力於軟體IC的研究，元件軟體設計準則也因此日漸受到重視。
以元件為基礎的軟體設計方法，元件的重用性是很重要的一個議題。有了可供利用的元件後，接下來要面對的就是組合元件的問題。要建立一個元件組合的環境，必須先有一個設計藍圖，規劃好如何管理元件、如何組合元件以及如何取得所需元件。
本論文以一樹狀關係圖 (稱為相依樹) 管理元件，利用樹的特性來表達元件間階層性的相依關係，並設計一套元件管理器系統，提供建立存放元件的元件庫、選取元件以及組合元件等功能。
要在眾多的元件中找出所需的元件並非易事，論文中提出Recipe方式，將使用者需求具體化，透過各元件特徵的描述，系統自動幫使用者選出符合需求的元件。
論文最後以近年來越來越熱門的LINUX作業系統核心為範例，將LINUX核心元件加入元件資料庫，供使用者選取，組合出其所需求的最佳核心，量身訂作一套符合功能需求的最佳作業系統核心。

It’s a goal to design a customized program based on his own requirement. To reach it, many people spent time to research on software IC topic. The design of component software has been pay attention to it.
The reusability of the component is an important issue for the component-base software design. After well-defined component, here comes the problem of composing components. To build a composite environment, we have to make a plan to manage components, compose components, and get the required component.
This thesis proposes a dependence tree to manage components. And design a component manager to provide functions of establishing component repository, selecting components, and composing components.
It’s not a easy case to choose components what we need from manifold components stored in component repository. We propose an easy way,Recipe, to specific requirement. By well-define component attributes, component manager will automatically choose the components fited in with requirement.
The rest of this thesis gives an example on the hot LINUX kernel code. We add LINUX kernel component to component repository, and provide user to select component by their requirement. Finally, after composing the selected component, user will get the best matching requirement kernel.
