동시공학으로의 제품개발 프로세스 개선을 위해서는 기업의 제품개발 조직 운영을 동시공학적 철학에 따라 개선하고 이를 지원하기 위한 컴퓨터 환경을 구축하는 두 가지 측면으로의 상호보완적인 접근방법이 요구된다. 한국적 기업환경에 적합한 동시공학시스템 K-CE시스템은 동시공학환경의 구현을 위해 핵심적인 제품정보 및 프로세스정보 관리, 워를로우 관리, 가상팀 지원의 동시공학 기반시스템 K-CE BASE와 프로세스의 병렬화 진행을 위한 프로세스 계획관리의 K-PMS, 네트윅을 통한 여러 부문 관계자의 설계 평가를 지원하는 제품개발 평가지원의 K-DESS로 구성된다. 이를 통해 기존의 제품개발 환경의 문제점을 극복하고 프로세스 간 지연요소를 제품개발 환경에서 설계변경의 최소화를 추구, 궁극적으로는 제품개발기간 단축과 원가 절가, 품질 향상의 동시공학 가치를 실현하고자 한다.

The purpose of this study is to develop the process to support and evaluate experts' decision making on vertical transportation planning in high-rise building constructions. Experts generally carry out the vertical transportation planning by heuristic methods, so there is a possibility that their decisions failed. The failure of the vertical transportation planning can be result in much loss of time and cost. The process presented in this paper evaluates experts' alternatives, organizes the results of the vertical transportation plan, and then leads to the systematic flow of materials and crews.

프로젝트 관리 성숙도(Project Management Maturity Model)란 기업 조직의 프로젝트 관리 관행이나 도구 및 기법 적용의 성숙도 단계를 정의한 것이며, 계량적인 성숙도 측정을 통해 프로젝트 관리의 장단점을 파악하고 개선하여 기업의 성과를 향상시키는데 그 목적이 있다. 본 논문에서는 프로젝트 관리성숙도를 활용하여 첫째, 한국 IT산업의 프로젝트 관리 성숙도를 측정하였고 둘째, 프로젝트 관리영역 중 범위관리와 원가관리의 계획 프로세스와 통제 프로세스간 성숙도를 비교 분석하였다. 연구 결과로 원가관리와 위험관리의 성숙도가 타 영역에 비해 낮아 개선의 노력이 필요하며, 범위정의 프로세스와 범위변경통제 프로세스간 프로젝트 관리 성숙도의 차이가 있는 것으로 나타났다. 본 연구의 성과로는 프로젝트 관리 성숙도 측정과 분석을 통해 기업의 프로젝트 관리 성숙도 향상과 프로젝트 성과 및 기업 성과 향상에 기여하는데 있다.

Practical and efficient application of lean construction, which has been proposed as an alternative to the limitations of traditional construction management methods, was developed to facilitate application on site and improve productivity through the fusion of traditional construction management methods. The concepts of Lean Time and Lean Cycle Time, which are the principles of lean construction, were introduced to eliminate waste and smooth flow production and pursuit of perfection, and the goal of establishing and improving the criteria for measurement and improvement was established and the information collection template was configured and applied to ensure reliability of measurement and analysis. Based on this, the project feasibility, reliability, and continuous improvement process were applied to the Field case to verify its effectiveness.

오늘날 세계화된 시장 환경은 기업간 협업 프로세스의 동적 구성을 요구하고 있으며, 웹 서비스 (Web services)와 비즈니스 프로세스 관리 (Business Process Management) 기술의 발전이 이의 구현을 뒷받침하고 있다. 임의의 기업과의 느슨한 구성(loosely-coupled)을 통한 동적 협업이 활성화됨에 따라, 프로세스의 서비스 품질 (Quality of Service)이 중요한 문제로 대두되고 있는데, 특히 단순한 단위 웹 서비스가 아닌 장기 실행 액티비티 (Long-termed activity)를 포함하는 협업 프로세스에서는 제한된 시간 내에 프로세스의 정상적 수행을 보장하는 것이 핵심적 요구사항이라 할 수 있다. 본 연구에서는 프로세스 수행 계획을 동적으로 생성, 관리함으로써 프로세스의 각 인스턴스들의 완료와 납기 준수를 보장할 수 있는 방법론을 제시한다. 본 방법론은 프로세스 인스턴스의 진행과정에 따라 중복(redundancy) 계획을 동적으로 수정함으로써 각 액티비티의 수행 시간과 신뢰성(reliability)을 독립적으로 관리한다. 본 방법론의 최적화 모델은 NP-hard로 증명되었으며, 본 연구에서는 최적화 모델을 위한 휴리스틱 알고리즘을 제시하고, 이를 실제 최적해와 비교하는 실험을 행하였다. 본 연구를 통해 보다 복잡한 기업간 협업환경에서의 수행 보장과 장애내감성 실현이 가능해 질 것으로 기대된다.

The role of information systems and business strategies of companies have attempted a variety of changes in the information technology environment that is displayed various. The advent of big data and knowledge-based analysis began to have great significance in the field of strategic planning for information systems specially constructed. The organization factors that affect the strategic planning of information systems through the application and practical Many researchers, technology, environmental have been introduced specifically. Input factors that affect the planning of information systems of these. In this study, it found the elements of the communication mechanism that exists between information and factors, the process of when developing a plan for information systems, and to study its relevance and convergence.

In multiple apartment construction project, BCWS is a critical management factor and has a great influence on the success of the project. Due to the many apartment buildings & facilities which produce numerous activities, there are several problems in making out a time schedule of work as well as production and management of precise BCWS from the allocation of resources. In this study, actual condition survey was executed in terms of the calculation and the management of BCWS. This study propose better solutions for efficient calculation of BCWS through the analysis of the problems and standard schedule & progress curves.

Demolition work is a precedence activity that is performed earlier than other remodeling activities. And demolition work is one of the critical path activities. So, demolition work is needed for systematic plan and management. However, contractors of the remodeling project established a rough plan and did not consider recycling wastes, safety of workers and structural stable of building. To improve this problem, a eco-friend process model of remodeling project is needed to be established. The process model is composed of five phases; 1) survey and analysis of general condition of demolition work, 2) prepare documents of demolition work 3) establishing demolition work plan, 4) demolition and inspection, 5) post-demolition management. Especially, demolition documents are based on establishing WBS, selecting the equipment and method, waste management and structure reinforcement. A process model of eco-friend demolition work is developed by using IDEF0 method.
