Driven by the explosive expansion and acceptance of the Internet and its multimedia front-end, the Web, a new generation of the modeling and simulation tools have come up with the name of Web-Based Simulation (WBS). Most of WBS libraries inherit its powerful advantages from Java. However, there are cases where explicit specification of models or interface objects is more desirable than the black-box programs. This paper presents an XML-based DEVS (Discrete Event System Specification) markup language for sharing simulation models on the Web. DEVS provides a system-theoretic formalism for the language while XML supports platform-independent data access. This paper focuses on the design of such a language.

최근 국내에서도 IT 프로젝트 관리의 중요성이 대두 되고 있으나, 중소규모의 프로젝트를 관리 함에 있어서 PMBOK(Project Management Body Of Knowledge)의 프로젝트 관리 이론과 PERT/CPM(Program Evaluation and Review Technique/Critical Path Method)과 같은 관리 기법들을 이용한 효율적인 프로젝트 평가 및 관리 사례는 많지 않는 실정이다. 철저한 프로젝트 관리를 위해서 소요되는 추가적인 인적 및 시간적 자원에 대한 투자가 현실적으로 어려우며, 평가 기준이나 기법들이 너무 복잡하고 난해한 것이 주된 원인이라 생각된다. 이 논문은 이러한 현실적인 상황을 고려하여, 중소규모의 IT 프로젝트에 적용하기 쉬우면서 효율적으로 활용할 수있는 시간과 인적자원에 대한 일정 시뮬레이션 모델을 통해 프로젝트를 평가하는 정량적 기준을 제공하고 이를 통해 프로젝트의 성공적 완수를 돕는데 의의가 있다.

Technology planning in the defense field aims to develop core technologies in order to develop weapon systems to satisfy the force integration period by researching and analyzing necessary technologies for weapon systems. In the past, core technology development projects were conducted by deriving core technology based on the main required operational capability. But in this case, there is the limitation that technologies which are necessary to develop weapon systems but do not directly affect required operational capability, such as system integration technologies, are not considered. In this paper, we propose a work breakdown structure-based technology research and analysis methodology that prevents vacant technologies by identifying core technologies that must be secured for the development of weapon systems at the component level. With the proposed methodology, it is possible to identify technologies that must be acquired to realize the required operational capability of systems or which must be secured even they do not affect the required operational capability.

Building information modeling (BIM) has been receiving attention as an integrated information model instead of CAD since the 2000s. BIM technology was first used in the architectural field and was later introduced to the civil engineering field. However, the government announced a plan for the application of BIM to 20% of all SOC projects from 2020, so the adoption of BIM technology is expected to accelerate. In order to successfully adopt BIM, a systematic structure should be supported for integrated design information and implementation technology. Also, it is important to establish the relationship between information systems because many complicated factors are intertwined in the construction industry. In this study, we propose a framework for constructing integrated information through identifying the information relations for introducing BIM in the civil engineering industry. We applied this framework to a bridge project to confirm its effectiveness. This study can be applied to the integrated management of the construction process and costs by introduction of a work breakdown structure (WBS) to BIM. In addition, this study is expected to contribute to the adoption of BIM in the civil engineering field through the proposal of information system standardization in this field.

Reviewing the previous researches related to SW quality, we find that they are mostly quality evaluation models for SW quality improvement and maturity-design models for software project management evaluation. There are few studies for the appropriateness of SW quality management by Quality Control(QC) functions. Moreover, they are bound for government's SW R&D projects in the view of the third party. Therefore, we propose means for the objective evaluation of SW quality management's appropriateness by QC functions. For this reason, there are three research proposes in our study as follows. Firstly, we produce problems for the evaluation of the existing government's SW R&D project management's appropriateness. Secondly, to overcome the drawbacks for the evaluation of the appropriateness of SW quality management, new appropriateness evaluation methods are proposed. Lastly, we investigate the availability and effectiveness of the appropriateness evaluation methods for WBS projects.

To plan a software project, the manager (1)make a work breakdown structure (WBS), (2) estimate efforts for each task, (3) assign employee to each task, and (4) estimate overall schedule. When software project becomes complicated, the possible combination of WBS, effort, and employee assignments dramatically becomes larger. Software planning tool can help software project managers to deal with this complexity. In this research, we discuss with a group of experts who work in software industry, to elicit practical requirements that should be considered in the software planning technique. Considering these requirements, we develop a software project planning tool APP (Automatic Project Planner) which provide effort estimation based on historical knowledge data and automatic human resource allocation. Our technique can be the basis of reasonable and practical software project planing.

This paper designs and proposes a file conversion process to IFC file, the international standard file format for BIM, in order to ensure mutual compatability and manageability among users of commercial BIM modeling and design softwares in the civil engineering area. The proposed process insert additional properties consisting of the properties of quantity calculation codes and properties of CBS/OBS/WBS standard classification scheme, to the three dimensional object shape information of the converted IFC files, using add-in converters for commercial BIM modeling softwares. In addition, a process of integrated use of IFC files for open web-based quantity, process(4D), and construction cost(5D) management is additionally designed and implemented. Based on these works, the ultimate goal of this study is to propose a novel process for integrated use of open web-based quantity, process(4D), and construction cost(5D), from the design stage of BIM modeling to the final construction stage in the civil engineering area.

In this paper, we propose a novel method for converting the existing 2D processes in the design and construction phase of civil engineering, to the future BIM-based processes. First, we compare and analyze the actual application processes of the outputs of the existing 2D method and the outputs of the 3D BIM method, for the whole process of BIM design of earthworks and road structures and integrated utilization of quantity, process(4D) and construction cost(5D), in view of life-cycle. The proposed method acquire the outputs of the design phase integrating IFC international common standard file information and CBS/OBS/WBS standard classification scheme information, and acquire the outputs of the construction stage by using an integrated utilization module for quantity, process(4D) and construction cost(5D). Ultimately, we intend to commercialize the step by step technologies for BIM design and construction in civil engineering by using the proposed method.
