As a part of the transition to the logistics 4.0 era, automation and unmanned technology have become the biggest issues in the logistics industry based on the development of various technologies such as AI and robotics. Due to the high workload of logistics activities, automation of loading operation is regarded as the one of the most important topics in logistics field. The automation of the loading operation is expected to provide a higher work efficiency as well as a relaxation of the labor intensity during the loading process. In addition, optimization of the loading space will leads to the reduction of environmental pollution and carbon emission by minimizing idle spaces. This study aims to support the automation of the loading process in various logistics environments by developing efficient 3-Dimensional (3D) loading algorithms applicable to the actual logistics environment of B2B and B2C cases. Realistic considerations such as unloading order preferences, height limitation, and product rotation are addressed to achieve such applicablities. The performance of the proposed algorithms was tested via realistic numerical examples.

국내에 있어서 프로그래밍 언어의 수요ㆍ공급분석에 따른 COBOL의 교육방향에 대한 연구

류영태 부산 외국어 대학교 2001 外大論叢 Vol.23 No.1

COBOL has been one of the most successful business programming languages for last four decades, However, to keep up with the fast-changing world of information technologies(IT), new powerful and effective programming languages such as Visual Basic(VB) and Java are emerging. In America, COBOL has maintained its reputation, partly by evolving to address changing technology and user needs, but in Korea, COBOL is losing its position as a top programming language in a business application area. This article reports the results of a survey of 96 business and industry organizations and 95 higher-educational institutions to investigate the status of COBOL as a programming language in Korea. The result shows that about 26% of IS managers still use COBOL for maintenance of legacy applications, but only 2% of IS managers are considering to use COBOL for new applications development. Currently, about 16% of academic respondents still include COBOL within their IS curricula, but most of them are seriously considering to replace or remove it in their curricula. Evidence suggests that languages such as VB, Java, and other web programming tools are increasingly preferred now for implementing application systems as organizations move from mainframe-based computing to more flexible computing environments utilizing client/server architectures and distributed systems. So, for firms that have made the decision to move their application development to other languages, retraining programmers experienced in COBOL to adopt the new languages is critical, as there is a scarcity of IT professionals to keep up with a new IT environment.

정보시스템 개발사례를 통해 살펴본 성공적인 정보기술 프로젝트 관리를 위한 제언(提言)

류영태 정보과학연구소부산외국어대학교 2002 情報科學論集 Vol.4 No.-

Information technology(IT) project management is a crucial issue for organizations today. A 1995 study in the USA found that 31 percent of software projects will be canceled before completion, and more than half the projects will cost an average of 189 percent of the original estimates. This study examines a real information technology project, which is Northwest Airlines' ResNet project in the mid-1990s and 2000s resulted in a new reservation system and increased profits for the company. It found that several important factors for the project success are active executive support, user involvement and requirement analysis, experienced business-side project manager, clear business objectives and project objective, clear project scope and planning, and management of changes in a sociological context. These findings will be fully applied into the other IT project management.

흡상전류비 방식 고장점표정장치의 전기기관차를 이용한전류비 산출 기법에 관한 연구

류영태,문은아 조선대학교 공학기술연구원 2018 공학기술논문지 Vol.11 No.1

The Fault location system is divided into the AT boost current ratio method and the reactance method. In the general railway section, the boost current ratio method is used. In the case of an accident in the power supply section, the wake current non-direction expression refers to a method of expressing the wake current flowing into both ATs supplying power at an accident point in proportion to the ratio. In order to obtain accurate current ratio characteristics, a forced ground fault test is carried out. The forced ground fault test is not available in poor ground and requires much time and preparation. In this paper, we propose a method to replace the forced ground fault test by measuring the current ratio data of AT neutral point by using electric locomotive as a load, and verify its usefulness by measuring the current ratio during operation of the electric locomotive in the operating section.

웹 서버와 데이터베이스관리시스템을 활용한 소규모 웹 기반 데이터베이스 시스템의 구축방법에 대한 연구

류영태 부산 외국어 대학교 2004 外大論叢 Vol.29 No.-

인터넷을 기반으로 하는 정보기술의 발전과 함께 전자상거래는 점차 활성화되고 있다. 이러한 전자상거래의 핵심은 데이터베이스의 응용이라고 할 수 있을 것이다. 따라서 데이터베이스 시스템의 구축에 대한 관심은 그 어느 때 보다 높은 것이 현실이다. 또한 이러한 데이터베이스 시스템을 웹을 통해 활용하고자 하는 요구가 그 어느 때보다도 높다. 본 논문에서는 Microsoft Access(액세스)에서 구축한 데이터베이스를 Microsoft IIS(웹 서버)에 올려놓고 웹 페이지 또한 액세스에서 작성하여 이를 웹 서버에 있는 데이터베이스와 연동하여 네트워크로 연결되어 있는 어떠한 클라이언트에서라도 웹을 통하여 사용할 수 있는 데이터베이스 시스템의 구축을 소개한다. 이러한 시스템은 데이터베이스가 웹 환경에서 어떻게 실행되는 지를 보여줄 뿐만 아니라 손쉽게 시스템을 구축할 수 있다는 것을 보여준다.

국내 시스템통합(SI)업체에서의 CASE 도구(Tools)의 활용실태에 관한 분석

류영태 대한경영학회 2003 大韓經營學會誌 Vol.16 No.7

The study explores the use of CASE tools. Several research questions are asked. I) Are CASE tools being used? 2) What features of CASE tools are being used? 3) Do system developers who use CASE tools use the same methodologies and perform the same activities that system developers who do not use CASE tools use and perform? 4) Do system developers who use CASE tools enjoy them and they perceive CASE tools as being useful? About 400 system developers participated in this study. The study indicates there are still a low usage of CASE tools in Korea. Within the companies that have adopted CASE tools, low percentage of developers are actually using the tools. The systems developers who use CASE tools are using formal systems development methodologies more often than systems developers who do not use CASE tools. The systems developers who use CASE tools spend their time more on the analysis and design than systems developers who do not use CASE tools. The system developers who use CASE tools are using only few of the functions within the tools. Finally, the results indicate that systems developers are basically neutral on whether they enjoy using CASE tools and whether they perceive the tools are useful.

IS 2002 표준교육과정에 입각한 국내 정보시스템 관련학과의 교육과정에 대한 분석

류영태,Ryu, Young-Tae 대한경영정보학회 2010 경영과 정보연구 Vol.29 No.3

본 연구는 독립된 학문분야로서의 정보시스템이 갖는 표준교육과정의 핵심구조를 파악하고 이를 기초로 국내 정보시스템 관련학과의 교육과정을 정보시스템의 표준교육과정과 비교분석하고자 하였다. IS 2002 표준교육과정의 핵심교과목을 기초로 국내 정보시스템 관련학과의 교육과정을 비추어 보았을 때 전체 교육과정 가운데 약 58%만이 이에 해당하였다. 이는 곧 독립된 학문으로서의 정보시스템이 아직 국내에서 충분히 학문으로서 독립성을 확보하지 못하고 있음을 나타내고 있다. 다만 핵심교과목에 있어서는 편중됨이 없이 대체로 각 영역에 고루 편성되어 있는 것으로 나타났다. 아울러 정보시스템이 경영학을 모태로 출발하였음을 나타내는 증거가 인접학문의 분석을 통해 확인할 수 있었다. 다양한 인접학문 가운데 거의 독보적으로 70% 이상의 교과목이 경영학분야(회계학 포함)로 편성되어 있음을 볼 수 있었다. 이는 한편으로 정보시스템이 경영학에 의존하는 바가 커서 경영학으로부터 독립하여 독자적인 학문영역을 구축하는데 장애가 되고 있음을 나타내기도 한다. 국립대학 및 상위권 대학을 중심으로 많은 대학에서 독립된 학과(학부)를 개설하는 대신에 경영학과(학부) 내에서 몇 개의 관련 교과목을 편성하는 수준으로 전공을 운영하고 있는 것도 이러한 현실을 반영하고 있는 것으로 보인다. The purpose of this research is an assessment of Information Systems(IS) curriculums in Korea based on the IS 2002 model curriculum. Out of the 201 Korean universities, 60 universities have the IS discipline as a major or a department having an independent curriculum. Out of these 60 universities, 38 universities(63.4%) have the IS discipline in the business schools while the IS discipline in the rest of universities is located under the social science school and others. Information Systems as a field of academic study exists under a variety of different names. The different labels(Information Systems, Management Information Systems, Computer Information Systems, Information Management, e-commerce, e-business, etc.) reflect historical development of the field, different ideas about how to characterize it, and different emphases when programs were began. The result of mapping the IS courses into the IS 2002 model curriculum supports the fact that management as a reference discipline that provides underlying theories for IS as a particular new discipline should be its academic home. Within the IS courses, information technology area is the most popular. and followed by information systems fundamentals area, information systems theory and practice area, information systems development area, and information systems deployment and management process area.
