S/W 제품계열(S/W Product Line)은 공통의 유사한 기능을 지닌 S/W 제품 또는 S/W 시스템의 집합을 의미한다. S/W 제품 계열을 통해 특정 영역의 시장과 용도의 요구사항을 만족하여 특정 S/W 제품 개발시 미리 구축된 S/W 아키텍처 등의 S/W 핵심 자산을 재사용하여 개발한다. S/W 제품계열 기반의 S/W 개발방식은 미리 구축된 S/W 핵심자산을 재사용함으로 처음부터 전체 시스템을 개발하는 방식보다 쉽고, 빠르게 S/W를 생산할 수 있다. S/W 기술 선진국들은 S/W 제품계열을 S/W 생산기술의 핵심 분야로 선장하고 중점적으로 기술 개발을 지원하고 있다. 미국의 CMU/SEI는 산업체 및 국방성과 함께 제품계열 프레임워크 4.0 (Product-Line Framework 4.0)을 개발하였고 유럽은 ITEA(IT for European Advancement) 프로그램에서 제품계열 기술 개발을 지원하고 있다. 그러나 국내의 경우 S/W 개발의 생산성 향상 방안으로 제품계열 기반 S/W 생산기술의 필요성을 인식하고 있으나, 기술 개발 투자는 미흡한 상황이다. 본 논문에서는 이러한 S/W 제품계열 생산을 위한 S/W 제품계열의 공통 아키텍처를 정립하는 것을 목표로 하고 있다.

S/W product line is a S/W product or a set of S/W system, which has common functions. We can develop a specific S/W product, which satisfiesrequirements of a particular market segment and a mission in a specific domain by reusing the core asset such as the developed S/W architecture through the S/W product line. S/W development methodology based on the S/W product line can develop a S/W more easily and fast by reusing the developed S/W core asset. An advanced country of S/W technology selects S/W product line as a core field of S/W production technology, and support technology development. In case of USA, CMU/SEI (Carnegie Mellon University / Software Engineering Institute) developed product-line framework 4.0 together with the industry and the Ministry of National Defense. Europe is supporting the development of product line technology through ITEA(IT for European Advancement) program. In this paper, we aim to construct reference architecture of S/W product line for production of the S/W product line.

Software product line is a software product or a set of software system, which has common functions. We can develop a specific software product, which satisfies requirements of a particular market segment and a mission in a specific domain by reusing the core asset such as the developed software architecture through the software product line. Software development methodology based on the software product line can develop a software more easily and fast by reusing the developed software core asset. Developed countries of software technology select software product line as a core field of software production technology, and support technology development. In case of USA, CMU/SEI(Carnegie Mellon University/Software Engineering Institute) developed product-line framework 4.0 together with the industry and the Department of Defense. Europe is supporting the development of product line technology through ITEA(IT for European Advancement) program. However, industries in our country understand the necessity of software production technology based on product line concept for the purpose of increasing productivity, it is not sufficient to invest for this technology development. In this paper, we aim to construct the common architecture of software product line for production of the software product line.

This study proposed new method to decide the reference model necessary for design PID controller. In generally, control design problems using the reference model have the following two factors. One factor is that numerical model of the controlled system can be obtained extremely, and the other is that specification for the closed-loop dynamic performance is pure moderate. Therefore, the control design procedure is essentially based on the partial reference model matching which offers a reasonable method to simplify the design and the controller configuration under the controlled system uncertainty. ITAE(Integral of time-multiplied absolute error) performance index and Kitamori method etc. which were used a reference model method had a limit to settling time and rising time of reference model that it arrived to steady state response according to the controlled system. On this study, if it only knew peak time of overshoot and settling time by measurement signal of the controlled system, it can be made the reference model easily. We proposed new method to improve performance index of the reference model superior to existing reference model index and illustrate the numerical simulation results to show the effectiveness of proposed control method design.
