A Study on the Analysis of SE Process Implementation for the Light Rail Transit Project
Kim, Chul Whan ; Han, Myeung-Duk ; Lee, Jae Hong ;
Journal of the Korea Society of Systems Engineering, volume 8, issue 2, 2012, Pages 1~10
This paper aims to analyze the result of SE Process Implementation on Light Rail Transit(LRT) Project. Currently the Light Rail Transit Project of Korea applies SE to the intermediate phase, that is, E&M phase which is a manufacturing and designing procedure. More seriously, the application effect of SE is not remarkable because it applies to some specific engineering fields like RAMS and it depends on superficial consulting of foreign companies with low SE support capability and investment capital. This study points out that the "Requirement Analysis" and "System Alternative Review" has not been conducted from the initial phase (basic plan and basic design) of the LRT projects. Several projects indicate that the amount of investments for SE activities through the Korea LRT project is relatively very small in comparison with the global capital which is about 10% of total project budget. Furthermore, Korea LRT projects have very few SE professionals and weak SE organization with no government directions and guide book for the efficient implementation of SE for the LRT projects.
A Study on the Systems Engineering Detailed Schedule for LRT Project
Han, Seok Youn ; Kim, Joo Uk ; Choi, Yo Chul ; Kang, Do Hoon ;
Journal of the Korea Society of Systems Engineering, volume 8, issue 2, 2012, Pages 11~17
Suppliers in light rail transit project makes a systems engineering management plan(SEMP) as a top level plan which has a SEMS and SEDS as an control and monitoring means. In this paper, we analyze the international standards and some related documents, and present the directions to make the SEMS and SEDS which have WBS, accomplishments, schedule, events, person in charge. And then customize the project management tool and make SEMS and SEDS of LRT project as an example. The research results can be applied in LRT project after tailoring based on the project.
An Investigation into Improving the Quality of Modern Weapon System Software Products: a Case Study
Choi, Taeyun Paul ; Lee, Hyo-Jin ;
Journal of the Korea Society of Systems Engineering, volume 8, issue 2, 2012, Pages 19~25
As modern weapon systems have evolved into embedded software systems, the capability to develop, install, and maintain high-quality software products is becoming increasingly valuable in today's competitive aerospace and defense industry. It is desirable, especially for government-contracted projects whose end-users are military personnel, that specific types of software quality elements are assured early during product development; namely, functionality and usability. Motivated by this need to approach improving software quality from a user's perspective, this paper presents a case study that analyzes system-level software integration testing results for a weapon system indigenously developed in the Republic of Korea. Quantitative data, such as software defect ratios and configuration change rates, are computed to observe meaningful trends with respect to functionality - represented by tests designed to verify the system's electrical signal interfaces - and usability, which is evaluated in terms of how often the initial human-computer interface had to be re-designed. Insights gained from these exercises are subsequently presented as a set of "lessons learned" to take into account when developing new software items for complex weapon systems.
On the Development of Reference Guidelines for Self-evaluation of Organization's Systems Engineering and Project Management Capability

Journal of the Korea Society of Systems Engineering, volume 8, issue 2, 2012, Pages 27~36
In modern systems, the operational capability of the system to the user needs is expanding rapidly to accommodate the size of the system, functionality, and interfaces are becoming increasingly complex. Accordingly, the systematic practice of project management and systems engineering in the system development process, as an important element in successful systems development is recognized. EIA/ANSI 632, ISO/IEC15288, the leading international standard for systems engineering and is the leading international standard on project management PMBOK. CMMI is also contains information about the activities of project management and systems engineering and worldwide basis to assess the maturity of an organization's ability to develop system being used. But CMMI model is too complex of structure and there are many overlap parts of contents. So there are many problems for members of organization understanding all of CMMI model, applying organization and, achieving improvement activity. In this study, through the analysis and integration between the model and the related standard coverage activities essential for successful systems development in organizations that require systems engineering and project management capabilities(SEPMC) for self-assessment and continuous improvement activities to provide useful reference guideline.
Study on Lecture Model for Systems Engineering Concept
Park, Joongyong ;
Journal of the Korea Society of Systems Engineering, volume 8, issue 2, 2012, Pages 37~45
About 20 years have passed since Systems Engineering(SE) was introduced in Korea. KCOSE(Korean Council On Systems Engineering) and KOSSE(The Korean Society of Systems Engineering) were established during that period and Korean SE community has increased quantitatively. But We can not answer "Yes!" for the questions "Did Korean SE community increase qualitatively? and How about SE education or training?" Many participants at SE lecture classes said that they were not able to understand SE concept. I analyzed current SE lecture materials and then proposed new model of SE concept lecture for SE novices. The new model consists of Vee diagram, life cycle model, PMTE paradigm, technical review, SE sample and definition of SE. I expect that the proposed model will contribute to upgrade a quality of domestic SE education.
Flooding and recovery system framework for Tsunami
Lee, Sun Kee ;
Journal of the Korea Society of Systems Engineering, volume 8, issue 2, 2012, Pages 47~55
Tsunami disaster, which ruined Japan Fukushima nuclear power plant sites in 2011 March, has raised not only the perception of that Tsunami and/or large scale flooding possibly surpass the design baselines for industry facilities and plants, but also the necessity to establish recovery system against flooding. This study suggests the framework for flooding and drainage system in compliance with flooding and drainage concept to define and identify requirements, functions, and components of the system with traceable relations. The framework with combination to CMMI engineering process is the base of corresponding high level system design.
A Study on Decommission Cost Estimation Framework with Engineering Approach
Lee, Sun Kee ;
Journal of the Korea Society of Systems Engineering, volume 8, issue 2, 2012, Pages 57~67
It is the sensitivity and confidentiality of nuclear power plant decommissioning cost that prevent detailed cost information to be released to the public, which causes some limitation to analyze and reuse the costs. This limitation to access cost information means that the lessons learned from preceding cost estimating may not systematically feed back into following cost estimates. As an alternative, decommissioning cost estimation framework is indispensable to reflecting available experience and knowledge for decommission costs. This study provides the cost estimation framework including data flow and structuralization based on engineering and bottom up approach to enhance decommissioning cost estimation.
