The Internet e-mail security software and standards, such as PGP (Pretty Good Privacy) and PEM (Privacy Enhanced Mail), have several limitations that should be overcome for their further applications to the Internet and network environments. In order to improve and reengineer those software, details of the As-Is software processing should be analyzed. One of the possible techniques for software analysis is IDEFO function modeling. Although IDEFO has been mainly used for BPR as one of the industrial engineering techniques, it has been rarely applied to the analysis of software processing and reengineering in computer and software engineering fields. Additionally, no sufficient details of PGP and PEM processing are analyzed in the literature. The objective of this paper is to demonstrate the application of the IDEFO to the systems analysis of the Internet e-mail security software as well as to provide software developers with the basis for software improvements.

This paper presents the results of analysis for the flexible computer integrated Construction(FCIC) system to adapt CALS on the construction industry. Acquisition and supply processes of the system are represented by IDEFO function models and FCIC information systems are briefly described in this paper. The model presented here used as a reference for the development of CALS system.

This paper presents the results of the systems analysis for the FCIM (Flexible Computer Integrated Manufacturing) system at the U.S. Tobyhanna Army Repair Depot, which is one of the RAMP (Rapid Acquisition of Manufactured Part) program sites for CALS implementation in the U.S. military. The FCIM system's acquisition and supply processes are represented by IDEFO function models and FCIM information systems are briefly decribed in this paper. The models presented here can be used at a reference for the development of CALS acquisition and supply systems. In addition. the distinction between input and control information on the IDEFO model it suggested from the practical modeling viewpoint.

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.

Among project delivery methods, Design-Build method is becoming an increasingly preferable alternative to traditional contracting method. The Design-Build delivery method was first introduced in Korea, 1975. But it still has been producing many problems. The previous researches had been suggested several ways to improve the Design-Build project delivery but it seemed to have had no effect whatsoever. This research proposes the success model for Design-Build delivery method through the 4 steps. First, find the proper modeling method. Second, establish the As-Is model for analyzing the circumstances of Design-Build method. Third, to begin with analyzing the As-Is Design-Build model and previous researches, establish the problem model. Finally, find success factors and circumstances through the overseas Design-Build system, and then establish the success Design-Build model.

Virtual construction (VC) system enables project manager to visually check mistakes in design materials by using virtual reality technology. In using VC system, to make 3D object by each construction element is still tedious work. This study suggests an improved method to make 3D object by using parameter-based 3D generation function. The IDEFO model to organize the process for the function. A VC system by this function was developed in this study and the function was verified by a bridge project in this system.

Models from different perspectives including functinal view, behavioural view and information view are necessary to implement complex systems such as CIM. It is difficult to integrate those models into a unified framework since they describe different aspects of the system for different purposes. However, modeling from different perspectives is often the case, and many workers are involved in developing a system. Thus, the transformation or interconnection mechanism is required to cope with the consistency problem between them and to save the efforts during development. In this study, a methodology to thansform the IDEFO model into a process flow model is proposed.

최근 건설 사업에서는 다양한 형태의 전산화 도구들을 현장에 적용하기 위한 노력이 진행 되고 있다. 그러나 철도시설과 같은 광역지역을 효율적으로 관리하기 위해서는 VR (Virtual Reality, 가상현실) 기술을 활용한 원격기반의 정보화 기법이 도입될 필요가 있다. 이를 위 본 연구에서는 VR과 Telepresence 기술을 통합한 실시간 현장 원격관리체계 구축 및 AR (Augmented Reality, 증강현실) 연동 방법론을 제안하며, 제시된 방법론의 실무 적용 성을 검토하고 있다. 이러한 가상건설지원 체계는 건설실무자와 시스템간의 실시간 상호작용을 가능하게 하며, 통합된 현장 진도 상황정보를 효율적으로 파악 할 수 있는 도구가 될 수 있을 것으로 기대된다.

In this paper, we suggest the system analysis method that integrate IDEFO and IDEFIX. Based on the method, we propose the procedure which can be used to build CALS/EC system in manufacturing industry. Also, applying the procedure and method to electronic company, we construct the CALSEC prototype system. With the three types of view-point, process, information technology and standard, we proceed the implementation of CALS/EC in manufacturing industry. We divide the electronic company's process into five core process, 1)processes-product concept planning process. 2)product development process, 3)procurement process, 4)delivery/distribution process and 5)customer service process.
