Abstracted Meta-model for Effective Capabilities Portfolio Management (CPM)
Lee, Joongyoon,Yoon, Taehoon,Park, Youngwon The Korean Society of Systems Engineering 2011 시스템엔지니어링학술지 Vol.7 No.1
The purpose of this paper is to provide an abstracted meta-model for executing Capabilities Portfolio Management (CPM) effectively based on DoDAF2.0. The purpose of developing an architecture is for beneficial use of it. A good set of architectural artifacts facilitates the manipulation and use of them in meeting its usage objectives well. Systems engineering methodologies evolve to accommodate or to deal with enterprise or SoS/FoS level problems. And DoD's Capabilities Portfolio Management (CPM) is a good example which demonstrates enterprise or SoS level problems. However, the complexity of the architecture framework makes it difficult to develop and use the architecture models and their associated artifacts. DoDAF states that it was established to guide the development of architectures and to satisfy the demands of a structured, repeatable method for evaluating alternatives which add value to decisions and management practices. One of the objectives of DoDAF2.0 is to define concepts and models usable in CPM which is one of DoD's six core processes. However, DoDAF and various guidelines state requirements for CPM rather than how to. This paper provides methodology for CPM which includes process and tailored meta-models based on DoDAF Meta Model (DM2).

프로젝트 관리(PM)와 시스템엔지니어링 관리(SEM)의 범위 및 관계
이중윤,Lee, Joongyoon 한국시스템엔지니어링학회 2014 시스템엔지니어링학술지 Vol.10 No.2
Put Abstract text here. Recently, the Korea industry need systems engineering technology more than yesterday. The systems engineering management function is needed to use the systems engineering engine process effectively. The systems engineering management function is overlapped a lot with project management function and has vague interface. The project management and systems engineering are two independent disciplines. So there are few references which address the scope and relationships clearly between systems engineering management and project management. This paper suggest the scope and relationships between systems engineering management and project management and revise the PMP and SEMP structure of Blanchard and Fabrycky. Followings are the key concept of this paper presenting. The project management(PM) composed of technical management and non-technical management. The technical management scope is same with systems engineering management. The non-technical management scope is composed of parts of enterprise support processes.

스마트 서비스 시스템 기반 스마트 팩토리 아키텍처 설계
이희제,이중윤,Lee, Heeje,Lee, Joongyoon 한국시스템엔지니어링학회 2017 시스템엔지니어링학술지 Vol.13 No.2
A new paradigm based on distributed manufacturing services is emerging. This paradigm shift can be realized by smart functions and smart technologies such as Cyber Physical System (CPS), Artificial Intelligence (AI), and Cloud Computing. Most architectures define stack levels from Level 0 (equipment) to Level 4 (business area) and specify the services to be provided between them. Because of their a rough technical specification, there is a limitation on how to actually utilize a technology to actually implement a smart factory service with this architecture. In this paper, we propose a smart factory architecture that can be utilized directly from the perspective of a smart service system by making the use of System Engineering Process and System Modeling Language (SysML).

Technology Readiness Level Assignment to Industrial Plant System Life Cycle
Salim, Shelly,Jo, Raehyeok,Lee, Taekyeong,Lee, Joongyoon The Korean Society of Systems Engineering 2015 시스템엔지니어링학술지 Vol.11 No.2
During the industrial plant system life cycle, required technologies are developed and assessed to analyze their performance, risks and costs. The assessment is called technology readiness assessment (TRA) and the measure of readiness is called technology readiness level (TRL). The TRL consists of 9 levels and through the TRL assessment, the technology to be developed and its components are assigned to their appropriate TRL. TRL assessment should be performed in each life cycle stages to monitor the technology readiness and analyze the potential risks and costs. However, even though the concept of TRL has been largely adopted by numerous organizations and industry, direct and clear assignment of target TRL for each life cycle stage has been overlooked. Direct mapping/assignment of target TRL for each life cycle has benefits as follow: (1) the technical risks condition of each life cycle stage can be better understood, (2) cost incurred if the technology development is failed can be analyzed in each life cycle stage, and (3) more effective decision making because the technology readiness achievement for each life cycle stages is agreed beforehand. In this paper, we propose a steel-making plant system life cycle and TRL assignment to each of the system life cycle stage. By directly assigning target TRL for each life cycle stages, we look forward to a more coordinated (in terms of exit criteria) and highly effective (in terms of technical risks identification and eventually prevent project failure) technology development and assessment processes.

시스템 엔지니어링 표준 기반 제철 플랜트 엔지니어링 업무표준 개발 사례
이태경,조래혁,이중윤,Lee, TaeKyong,Cho, RaeHyuk,Salim, Shelly,Lee, JoongYoon 한국시스템엔지니어링학회 2016 시스템엔지니어링학술지 Vol.12 No.1
Plant engineering industry is considered as a key industry which will drive the future of Korea. However, Korean plant engineering companies have recently made huge losses in overseas businesses and the lack of engineering capability is pointed out as a main cause of this situation. Unlike Korean plant engineering companies, world leading engineering companies such as Flour and Bechtel have their own systems Engineering Standards/Guides ensuring successful fulfillments of the concept and basic design processes. An engineering standard for an organization is an essential means to shorten the time for engineering design, to maintain the engineering quality and to secure the engineering efficiency in the development of the complex system. Korean plant engineering companies'lack of engineering capability comes from the absence of the engineering standard. In the paper, we have developed a steel-making plant engineering standard based on a systems engineering standard. We chose both ISO/IEC/IEEE 15288 and NASA SE Handbook as main reference standards. First, we have introduced a life-cycle definition and a physical hierarchy of a general steel-making plant. Then we have introduced detailed engineering processes of each life-cycle stage. The full scope of the study was from the feasibility study to the basic design but in the paper, we have only introduced detailed engineering processes and exit criteria for the feasibility study and the concept design.
