Information systems development entails planning, analysis, design and construction phases. The analysis phase identifying user requirements is the most important of these phases. Since unidentified defects in the early phase causes increased work and costs as development proceeds, the quality of analysis results affects the quality of the resultant system. Major tasks in the analysis phase are data modeling and process modeling. Research on building a knowledge-based system for data modeling have been conducted much, however, not sufficiently for process modeling. As a system environment with high user interaction increases, research on process modeling methods and knowledge- based systems considering such environment are required. In this research, a process modeling framework for information systems with high user interaction is suggested and a knowledge-based system for supporting the suggested framework is implemented. A proposed model consists of the following tasks: event analysis, process analysis, and event/process interaction analysis. Event analysis identifies business events and their responses. Process analysis break down the processes of an enterprise into progressively increasing details. Decomposition begins at the function level and ends when the elementary process level is reached. Event/process interaction analysis verifies the results of process analysis and event analysis. A knowledge-based system for supporting a proposed process modeling framework is implemented in a web-based environment.

Nowadays, automated modeling system for steel margin based on interactive user interface has been developed and applied to the production design stage. The system could increase design efficiency and minimize human error owing to recent CAD technique. However, there has been no approach to the pre-nesting design stage at all in early modeling process especially where ship model should be handled at more than two design stages using AVEVA Marine. A designer of the design stage needs artificial intelligence system beyond modeling automation when 3D model must be prepared in early modeling process using AVEVA Marine because they have focused on 2D nesting traditionally. In addition, they have a hard time figuring out the model prepared in previous design stage and modifying the model for steel purchase size in early modeling process. In this paper, artificial intelligence modeling system for automated application of steel margin in early modeling process using AVEVA Marine is developed in order to apply to the pre-nesting design stage that can detect effective segments before a calculation to find if a segment locates near block butt boundaries by filtering noise segments among lines, curves and surface intersections based on IT big data analysis.

본 연구는 제품디자인 개발과정에서 많이 활용되고 있는 워크스테이션(workstation)의 하나인 알라아스(Alias)를 활용하여 정확한 3차원 모델 링 데이터를 구축하는 과정을 비디오 개발 과정을 통해 제시하였다. 먼저 알리아스(Alias) 모델 링의 기본이 되는 NURBS 곡선의 특징과 표면 생성 방법을 파악하였다. 기본적인 표면을 생성한 후 사실적인 이미지 표현을 위해 적용하게 되는 질감표현(texture), 조명(lighting), 렌더링(rendering) 방법을 파악하였다. 제품 디자인의 모델 링에 필요한 이러한 요소들을 비디오 디자인 개발 과정을 통해 종합적인 활용방향을 제시하였다.

최근 들어 소프트웨어 개발에 있어서 사용자 인터페이스가 차지하는 비중이 급증하고 있다. 이로 인해 스윙, MFC, Web 2.0 등과 같은 다양한 사용자 인터페이스 개발 관련 기술들이 소개되고 있다. 그러나 현재 대부분의 소프트웨어 개발에 있어서는 사용자 인터페이스 부분과 비즈니스 부분을 별도로 개발하는 프로세스로 진행되고 있다. 이로 인해 통합 과정에서의 어려움, 개발 기간의 연장, 개발 모델의 재사용성의 저하등과 같은 문제점들이 발생하고 있다. 즉, UI 모델링이 체계적이고 계층적이지 못하며, UI 모델링과 비즈니스 모델링간의 일관성있는 통합 기법을 제공치 않아, 구축 모델의 확장성과 재사용성의 저하를 초래하고 있다. 본 논문은 이를 해결하기 위해 개발 단계의 추상화 수준에 따른 계층적 메타모델을 사용해서 단일화되고 체계적인 UML 기반의 사용자 인터페이스 모델링 프로세스를 제시한다. 이를 위해, 개발의 성숙도에 준거하여 PIM/PSM으로 UI 모델의 모델링 요소를 계층화하여 메타모델을 제시한다. 3 단계 모델링(개념/명세/상세)에 의해 UI 및 비즈니스 메타모델을 적용해서 UI 모델링과 비즈니스 모델링이 통합된 계층적인 모델링 프로세스를 정립한다. 제시한 프로세스를 인터넷 쇼핑몰에 적용해 봄으로써 실효성을 제시한다. 실험 결과를 통해 계층적 UI 메타모델 및 프로세스가 체계적이고 계층적인 UI 모델을 구축할 수 있다. 이는 모델의 품질과 재 사용성을 향상시킬 수 있었다.

The software group in Giant Magellan Telescope Organization (GMTO) is developing the GMT Software Development Kit (SDK) for the device control and the telescope operations. The SDK is dived into the modeling and the operation defining. In the modeling process, Domain Specific Language (DSL) can validate the availability of a model and generate a skeleton code automatically. After the modeling, the developer can simply define the device operation. All devices are connected via EtherCAT, and the SDK simplifies the network connection. This presentation will give an overview of the modeling process and development examples using the GMT SDK.

This study reviews the concept of Integrated Logistic Support(ILS), ILS standards, ILS elements, and the processes of developing ILS elements and Logistics Support Analysis(LSA). It also examines the potentials of applying ILS development process to building CALS systems in commercial sectors in order to accomplish business process innovation and achieve life-cycle cost savings in product and equipment management. In order to utilize the ILS approach for commercial industries, we need customizing the process of Logistics Support Analysis defined in MIL-STD-1388-lA. The success of ILS implementation depends on the determination of the range of ILS elements in relation with the application environment, and the appropriate development of those elements. During the development process, in order to analyze and design logistics flow processes and supporting activities, we suggest the object-oriented logistics process modeling approach with basic concepts and constructs embedded in objects. Several diagrams including Class Diagram, Class-Instance Diagram, and Integrated Instance Diagram, are provided. Simple Steps to follow are suggested for the analysis and design of inter-organizational logistics flow and support processes. The outcomes of the study are expected to contribute to stimulating the utilization of ILS concepts and development process during building commercial CALS systems.

Entity-relationship modeling for designing relational database is a very complicated thinking process that requires extensive knowledge and experiences. It is very likely that designers make mistakes in this process. In order to minimize the mistakes, a systematic method to guide the thinking process is needed. In this research, an entity-relationship modeling system is developed, which resolves the whole process of information modeling, data modeling, and functional dependency relationship analysis into small and simple decision-making steps. Therefore, it can reduce the possibility of making decision errors and improve the efficiency of the modeling process. It's functionality and efficiency is verified through some modeling examples. It is expected that the modeling system can be commercialized, if some functions are added, such as detection, warning, and correction of decision errors, and educational help.

New product development is a complex managerial process which involves multiple functional groups, each with a different perspective. Quality function deployment (QFD) is a new product development process which stresses cross-functional integration. QFD provides a specific approach for ensuring quality through each stage of the product development and production process. This paper provides an overview of QFD including its concepts and methods, and then proposes an integrated approach to formulating and solving the QFD process. This paper also discusses issues associated with the prescriptive modeling of QFD.

Mathematics educators have examined mathematical modeling, where students tackle authentic real-life problems and develop problem-solving strategies with a sense of agency. However, few empirical studies have been conducted to illuminate the developmental process of teachers' competencies in mathematical modeling, particularly for elementary school teachers. Scholars have noted that elementary mathematics teachers can effectively teach mathematical modeling by designing tasks that consider students' abilities and preferences. In this vein, this review paper introduces a study conducted by Jung (2023), which examines the developmental process of an elementary school mathematics teacher's competencies in mathematical modeling and how she overcame related challenges.
