To promote the off-site construction (OSC) in Korea, technical innovation applied to each phase, such as design, engineering, factory production, and site assembly, is important and equally necessary is the development of management and operation methods that are different from existing construction production methods. However, the current OSC-related studies in Korea are conducted from the technical development viewpoints, such as construction methods. Additionally, few studies have been conducted to derive a management measure for successful OSC projects. Therefore, studies to derive a management measure based on a clear understanding of the core success factors of OSC projects are required. This study aims to analyze several studies related to the success factors of OSC projects conducted overseas and to show its core implications for the successful management of OSC projects in Korea. We expect this study to improve the viability of OSC projects, which will be expanded in Korea in the future.

In a large owner organization, a program manager of multiple maintenance and remodeling projects has experienced increasing scale and complexity of coordinating the M/R projects with in-house technicians who belong to multiple trade shops. This paper proposes a dual-level hierarchical planning strategy that consists of a program master plan in the long-term horizon and a master construction schedule in an operational scheduling window. A rolling horizon approach to the program master plan is proposed to deal with the external uncertainty of unknown stream of project requests. A resource-constrained scheduling algorithm is developed to generate the master construction schedule in a scheduling window. During development of the algorithm, more emphasis is placed on long-term organizational resource continuity, especially flow management of program constraint resources, than ephemeral events of an individual activity and project. Monte Carlo simulation experiments of three scheduling windows are used to evaluate the relative performance of the proposed scheduling algorithm against three popular scheduling heuristics for resource-constrained multiple projects.

Objective of Urban regeneration is a recovery of urban utilities through a physical, environmental, cultural, industrial and economic regeneration. The current paradigm of urban regeneration is not a simple redevelopment as physical redevelopment or improvement. This study is proposed that value system management applied the benefit management, value system, Quality Function deployment for a value conflict of urban regeneration. There is a reason to conflict value that value system is unstructured. Because this study is proposed to establish the process of value system, and applied this process to Se-woon 4th area urban regeneration project. This study is analyzed to divide value system of urban regeneration program into city level, district level, zone level in district. An analysis of value system obtained through '2020 urban master plan', 'the downtown recreate a comprehensive plan', 'Se-woon New town plan'. It is proposed that value system management method through Between values correlation analysis and the order of priority deduction. These are obtained to use Delphi technique and Analytic Hierarchy Process(AHP)

Construction Projects have mutual collaborative structures among various participants for common objectives. Most of all the design project which is the initial phase in the project is crucial for determining project overall quality and requires intimate and continuous relations between project participants. Thus, this study suggests Design Collaboration Management System for successful performing projects through cooperation among participants in the initial stage of projects. First, expert interviews were performed to figure out present conditions of design collaboration management and problems. The factor analysis was applied to draw owner's collaboration factors and engineer's collaboration factors. Based on those factors, this study suggests design cooperation management process which gives a framework for systematic management method. Through the process the design collaboration management system was developed which helps owner/designers/engineer's co-work. The System suggested from this study realizes systematic information management tool and through that it is expected to improve design product;'s quality, and further contribute the advancement of project.

Many companies are executing big data analysis and utilization projects to legitimize the development of new business areas or conversion of management or technical strategies. In Korea and abroad, however, such projects are failing because they are not completed within specified deadlines, which is not unrelated to the current situation in which the knowledge base for big data project risk management from an engineering perspective is grossly lacking. As such, the current study analyzes the risk factors of big data implementation and utilization projects, in addition to finding risk factors that are highly important. To achieve this end, the study extracts project risk factors via literature review, after which they are grouped using affinity methodology and sifted through expert surveys. The deduced risk factors are structuralize using factor analysis to develop a table that categorizes various types of big data project risk factors. The current study is significant that in it provides a basis for developing basic control indicators related to risk identification, risk assessment, and risk analysis. The findings from the study contribute greatly to the success of big data projects, by providing theoretical basis regarding efficient big data project risk management.

This paper deals with an approach to boost the public sector SI market in Korea. In order to promote competition powers of the software industry in Korea, a software industry promotion law has been issued, which restricts large SI companies from competing in the public sector system integration market. However, naturally many SI projects in public sectors are too large and complicated to be carried by small and medium size companies. This paper proposes an approach to reform the SI market for those small and medium size SI companies.

국내에도 BIM이 도입되어 다수의 프로젝트가 수행되고 있으며 정부에서는 정책적으로 BIM 확산을 도모하고 있다. 하지만 기술적 한계와 이해의 부족으로 인한 여러 가지 부작용이 발생하고 있으며 특히 현재 도입이 가장 활성화 되어 있는 설계 엔지니어링 업무 영역에서 보완이 필요한 부분도 가장 많이 발생하고 있는 실정이다. 이에 본 연구에서는 기존의 설계사례의 분석을 통해 협업 관점에서 MEP 작업요소의 주요 이슈를 도출하고 건축기계설비의 관점을 좀 더 정확하게 이해할 수 있도록 타 공종 기준의 MEP 작업요소 이해를 위한 기준을 제시하였으며 이러한 내용이 앞으로의 국내의 BIM 프로젝트의 수행과 지침의 작성에 활용될 수 있는 기초자료로 활용되기를 기대한다.

오픈 소스 소프트웨어에 대한 관심과 함께 많은 연구가 진행 중이며, 오픈 소스 소프트웨어 개발을 지원하는 커뮤니티도 다수 존재하고 있다. 오픈 소스를 활용한 개발비용을 예측을 위해선 오픈 소스의 개발 기간을 예측하여야 하지만, OSS 개발 방법에는 개발 기간을 산정하는 것이 미비하다. 그리하여 본 연구에서는 OSS 커뮤니티에서 개발기간을 산정하는 것에 대하여 XP 개발 방법의 사용자 스토리 카드를 이용한 산정법을 적용하여 활용하는 연구를 하고자 한다. 이를 위해, XP의 산정법을 OSS 커뮤니티에 적합하게 수정하였다. 또한 제안한 방법을 실제 SourceForge.net의 프로젝트 중 버그와 추가사항의 기록이 많은 프로젝트에 적용하여 그 가능성을 입증하였다.

모바일 응용 어플리케이션의 규모가 점점 늘어남에 따라서 하나의 모바일 어플리케이션을 개발할 때에도 큰 프로젝트 그룹이 형성되어 다수의 개발자가 동시에 개발을 진행하게 된다. 본 논문에서는 안드로이드 모바일 응용 어플리케이션 개발환경을 웹을 통해서 다자간 공유 형식으로 개발할 수 있는 통합 개발환경을 설계하고 구현하였다. 본 논문에서 개발한 통합 개발환경을 이용하면, 웹 브라우저를 통해서 프로젝트 개설, 버전 관리, 공유 및 동기화를 할 수 있어서 어느 환경에서든 웹을 통해서 그룹화하여 모바일 어플리케이션을 개발 할 수가 있다.

현재 소프트웨어 요구사항은 전체 소프트웨어 개발 프로세스를 거쳐, 완성된 제품 인도 시 인수 기준으로 작용한다. 그러므로 이런 요구사항은 개발주기 전체에 걸친 매우 중요한 관리 수단이다. 그러나 국내 다수의 중소기업은 이러한 문서화에 시간 및 비용이 부족하여, 개발 문서의 부재 혹은 코드와 문서가 불일치한 것이 현실이다. 이 문제를 해결하기 위해, 자동 프로젝트 문서 발생기(Automatic Project Document Generator)를 제안한다. 제안한 발생기를 통해 요구사항 스펙과 소스 코드 간 동기화로 요구사항 대로 개발이 진행되는지 확인 가능하다.
