최근 기존 정보시스템에 고객이나 사용자의 다양한 요구사항이나 기업의 환경 변화를 반영하여 새로운 정보시스템으로 재구축하는 경향을 보이고 있다. 이를 통해 기업들에서 경쟁 우위를 선점함으로써 보다 우세한 경쟁력을 갖출 수 있다. 본 논문에서는 정보시스템 재구축을 위한 프로세스 모델링(Process Modeling)과 데이터 모델링(Data Modeling)을 체계적으로 수행하는 방안을 제시하고, 이를 실제로 적용한 사례를 보여준다. 정보시스템의 전체적인 관점에서의 요구사항 및 기존 정보시스템의 미비사항을 분석하여 정보화 대상을 추출하는 프로세스 모델 분석(Process Model Analysis) 단계와 정보화 대상을 개념 모델로 전환하는 논리 데이터 모델링(Logical Data Modeling) 단계, 실제 컴퓨터에 저장하여 사용하는 물리 데이터 모델링(Physical Data Modeling) 단계로 구성된다.

This paper utilizes the FIDO methodology (Function, Information, Dynamic, Organization modeling) which is an enterprise modeling tool that can describe inter-organizational interaction (specifically between prime and sub contractors in this experiment). FIDO follows the standard IDEFO rules in order to demonstrate how a cascading information flow can evolve from a customer to a prime to a subcontractor in a concurrent manner, in a supply chain environment. Background on these processes is presented, followed with the newly derived process and methodology. This is presented in a supply chain management context, and results from an actual experiment at Motorola utilizing subcontractors that supply custom machine parts is presented and reviewed.

Various types of building information should be linked to 3D model objects for their effective use by stakeholders. Because Building Information Modeling (BIM) based on 3D is used by different stakeholders, the created BIM need standard guidelines for each purpose, as, for example, for quantity take-off. Thus, this study was conducted to propose guidelines for BIM modeling for quantity take-off in the framework, especially, in the concrete and form. The proposed guidelines adopted each element of the BIM model based on an analysis of the problem of the general BIM model. Moreover, the usability and accuracy of the reinforced structure modeling guidelines were verified by comparing the quantity of the commercial estimation software and the modeling quantity using the proposed modeling guidelines.

에이전트에 대한 연구는 최근에 들어와 그 응용분야가 점차 확대되어 가고 있으며, 에이전트를 근간으로 하는 소프트웨어도 점점 복잡화, 대형화되고 있는 추세이다. 이에 따라 에이전트를 근간으로 하는 소프트웨어 개발 방식도 좀 더 체계적이며 공학적인 접근이 요구되고 있다. 본 논문에서는 에이전트 기반의 소프트웨어를 효율적으로 모델링하기 위하여 에이전트 추출, Intra agent modeling과 Inter agent modeling 기법과 방법론을 지원하는 Agent-Oriented Modeling Tool에 대해 소개한다. 에이전트 추출은 실세계에 존재하는 객체들로부터 에이전트를 추출하는 방법을 사용했고, Intra agent modeling에서는 에이전트의 내부를 Goal, Belief, Plan, Capability로 나누어 각각의 모델링 방법을, Inter agent modeling에서는 다중 에이전트 시스템에서 에이전트의 Mobile과 에이전트간의 메시지 교환을 중심으로 한 모델링 방법을 제안한다.

Game theory has been regarded as a useful theoretical tool for modeling the interactions between distinct entities and thus it has been harnessed in various research field. In particular, research attention has been shown to how to apply game theory to modeling the interactions between malign and benign entities in the field of wireless networks. Although various game theoretic modeling work have been proposed in the field of wireless networks, our proposed work is disparate to the existing work in the sense that we focus on mobile malign node detection problem in static wireless sensor networks. More specifically, we propose a Bayesian game theoretic modeling for mobile malign node detection problem in static wireless sensor networks. In our modeling, we formulate a two-player static Bayesian game with imperfect information such that player 1 is aware of the type of player 2, but player 2 is not aware of the type of player 1. We use four strategies in our static Bayesian game. We obtain Bayesian Nash Equilibria with pure strategies under certain conditions.

Industry Foundation Classes(IFC) is the core product schema for ensuring the interoperability of information in Building Information Modeling(BIM) environment. However, since current IFC is mainly focused on building structure. there are limitations in the generation of functional information of components when applied to civil infrastructures. Previous studies have proposed IFC-based new entities for the civil infrastructures, it takes long time to support them in BIM authoring software packages. In this study, we proposed practical rules to apply IFC-based information modeling using BIM authoring software and additional new entities for the civil infrastructure through attributes and information mapping. The availabilities of proposed method were examined using the rail and sleeper information models based on an extended IFC data schema for the railway infrastructures.

Enterprise integration, which aims to enhance an enterprise's competitive edge, requires a highly structured product information model as a common product database. Previous research works on this issue have been narrowly focused on the transformation of product information between various operation areas, leading to a situation where enterprise integration lacks a formal method of information modeling. In this paper, research works and issues surrounding product information modeling for enterprise integration are reviewed, and the requirements for a product information model are identified. A product information model called L3DPIM (Layered Three Dimentional Product Information Model) is proposed, which is based on a feature-based design process. This model is expected to serve as a modeling paradigm for enterprise integration.
