基于構件的產品線方法在數控領域的應用：在復雜的大型數控軟件系統的開發過程中，往往存在開發成本高、周期長、復用性差等特點。本文針對數控領域中的各個系統存在著大量的相似性和共同點，提出了一種面向整個數控領域的軟件開發過程---基于構件的產品線方法，并提出了其產品線構架和核心資產庫框架。由此實現數控領域中的大力度的軟件復用、降低開發成本、縮短開發周期，并支持數控系統用戶對產品的定制性要求。

Abstract: There are many problems in the development process of large-scale and complex
CNC system, such as high cost, long period of development and poor efficiency of reusability.
According to the comparability and intercommunity in each system in the domain of CNC, a
development model that oriented domain of CNC is introduced which is based on
component-based software product line method. The architecture of software product line and the architecture of core asset are given, which can enhance efficiency of software reusability, reduce cost, shorten period of development and meet the demand of user’s customization.
