다양한 환경 속에서 기업이 업무의 효율성과 효과적인 업무처리를 해결하기 위해서 핵심정보시스템으로 워크플로우를 도입하고 있다. 최근에는 워크플로우 확장으로 비즈니스 프로세스 관리(BPM: Business Process Management)가 기업 소프트웨어 시장의 가장 중요한 부분을 차지하고 있다. 비즈니스 프로세스 관리에서 워크플로우는 핵심적인 역할을 수행하고 있지만, 워크플로우 연구의 대부분은 복잡한 업무의 정확한 실행 순서를 찾기 위한 시간적인 제약들에 집중되어 있다. 그런 이유에서 워크플로우 스케줄링의 대부분은 처리해야 할 다양한 자원의 모델링에 집중되었으며, 자원과 연관된 제약조건에서의 워크플로우 스케줄링에 대한 관심은 미흡한 편이다. 본 논문에서는 자원할당 제약조건에 따른 워크플로우 스케줄링에 적합한 CTR(Concurrent Transaction Logic) 기반의 변형 템플릿(Transformation Template)과 논리적 프레임워크를 제안한다. 변형 템플릿은 워크플로우 변형 템플릿(Workflow Transformation Template)과 제약조건 변형 템플릿(Constraint Transformation Template)으로 구성된다. 이 변형 템플릿은 기존의 워크플로우를 자원할당 제약조건 하에서 새로운 워크플로우를 논리적으로 표현하는데 용이하게 사용할 수가 있다.

철근공사는 거푸집공사와 더불어 건축물의 구조적 안정성과 내구성 및 공기에 가장 큰 영향을 미치고 있는 공사이다. 그러나 국내 철근 콘크리트 공사는 철근현장가공조립을 주로 하고있어 낮은 생산성을 갖고 있는 실정이다. 따라서 본 논문은 생산성 향상을 위해 철근현장가공조립 프로세스를 부가가치 생산성향상을 위한 낭비요소를 분석하였다. 낭비요소 분석은 비가치창출 작업으로 인해 발생하는 요소로 철근현장가공조립의 가치분석을 통해 부가가치를 극대화 하고자 하였다. 그 결과 가치창출작업들이 비가치창출 작업보다 월등히 적다는 것으로 분석되었다. 특히, 본 논문에서 낭비는 불필요한 작업 단계와 인력, 장비, 자재, 시간 등에서 낭비되고 있었다. 또한 흐름생산이 되지 않고, 과잉생산을 하고 있는 것으로 조사되었으며, 가치의 변화가 필요한 것으로 분석되었다. 본 논문에서는 부가가치 생산성 향상을 위해 프로세스 상에 내재되어 있는 낭비요소를 분석하여 부가가치를 창출하는 가치창출 작업을 최대화하고, 비 가치창출작업을 최소화하는데 목적이 있다.

Construction Productivity is one of the most important elements in construction management. It is used in construction process scheduling and cost management, which are significant sector in construction management. It is important to make appropriate schedule and monitor how works are done within schedule. But construction project contains uncertainty and inexactitude, modifying construction schedule is being an issue to manage construction works well. Even though prediction and monitoring of productivity can be principal activity, it is hard to predict productivity with manager's experience and a standard of estimate. A large number of factors influencing productivity, such as drawing, construction method, weather, labor, material, equipment, etc. But current calculation of productivity depends on empirical probability, not consider difference of each influencing factor. In this research, the aim is to present a productivity predicting regression model of form work, which includes effectiveness of influences factors. 5 variables existed inside form work are selected by interview and site research based on literature review of existed various productivity influencing factors. The effectiveness and correlation of productivity influencing factors are analyzed by statistical approach, and it is used to make productivity regression model. The finding of this research will improves monitoring and controlling of project schedule in construction phase.

An efficient management of product information is critical to the enhancement of corporate competitiveness. Product information is often distributed in term of organization, geography, and time. With the rapid increase in the use of Internet or its associated Web and intranets, it has been accelerating to integrate the distributed information. In this research, a Distributed, Open, Intelligent Product data Management system, namely DOI-PDM, is developed. This system deals with product information following the STEP standard, and its operation is controlled by a Web-based workflow management system. CORBA is employed to ensure interoperability among distributed objects. It is intended to achieve openness by using various standards, such s STEP, KQML, SGML, and WfMC specifications. One major difficulty in managing it needs also be properly modified according to the dynamics. It however is very hard to have a prior anticipation to the dynamics. It however is very hard to have a prior anticipation to the modification requirements in practice. We introduce a process adaptation model and a use of intelligent agent technology. An agent is delegated to modify process definitions during run-time. A method of agent implementation and a proper communication scheme among te agents are proposed. Also developed in this research is a STEP-based content search system which can co-work with the agents by providing relevant product information that the agents require.

As the size and complexity of network increase Distributed System Management (DSM) will be significant issue within information network in order to increase the high reliability and to improve the flexibility of network management. The OSI management model has several problems. The key problems are that it does not fully address the problem of how to develop communication protocol in support of DSM and how to classify the management connection criteria. In this paper to solve first problem described above this paper propose the connectionless CMIP to accomplish for effectively managing the distributed management managing systems to handle the dynamic informations. To work out second problem we introduce the connection criteria in the hierarchy of management system and finally evaluate the efficiency of a suggested protocol during cooperative negotiation among the managing system.

The OSI management model has several problems. The key problems are that it does not fully address the problems of how to develop communication protocol in support of DSM, and how to classify the management connection criteria. In this paper, to solve first problem described above, this paper propose the connectionless CMIP(Common Management Information Protocol) to accomplish for effectively managing the distributed management system, and indicate its efficiency; this protocol is available to negotiate among the managing systems, handle the dynamic information. To work out second problem, we introduce the connection criteria in the hierarchy of management systems, and finally evaluate the efficiency of a suggested protocol during cooperative negotiation among the managing systems.

Research sponsored by the Korean Government investigated the establishment of a risk management process by Korean contractors involved with plant projects in the Middle East. This research effort builds upon the work completed by the Construction Industry Institute (CII), called the International Project Risk Assessment (IPRA) tool and method, and also explored how CII's Project Definition Rating Index (PDRI) could be incorporated to improve project planning by addressing risks and scope development issues. Specific findings and recommendations were developed including the creation of the Contractor Critical Areas of Concern (CCAC) risk screening tool for Korean contractors pursuing Middle East oil and gas projects.

In recent years, dramatic advances in information technology have motivated the construction industry to improve its productivity. Computer-based information technology includes Computer-Aided Design (CAD), Computer-Aided Engineering (CAE), Computer-Aided Manufacturing (CAM), Enterprise Resource Planning (ERP), Digital Mock-Up (DMU) and Product Data Management (PDM). Most construction industries are trying to apply these technologies for quality improvement, reduction of construction time and cost. PDM is very useful for managing data and process related to product design and manufacturing. PDM system has various functions such as drawing and engineering document management, product structure and structure modification management, part classification management, workflow management, and project management. In this paper, PDM system was applied to the design of steel-concrete composite girder bridge. To make a practical guidance for PDM implementation to bridge design, the procedure for its implementation was presented. Consequently, this paper could be useful to enhance the efficiency of bridge design.

The National Education Information System(NEIS) has been utilized in primary and secondary schools. In this paper, we consider the NEIS should be used not only for educational administration affairs, but also for a lifelong management of national human resource. The current School Information Management System(SIMS), including the NEIS, is unsatisfactory due to the insufficiency of actual field suitability and end-user's conveniency. To this, we have devised improvements of the SIMS in the seven problem areas: ) The core business process of the school should be analyzed sufficiently and reflected in SIMS. (2) We should fully utilize groupware functions which activate the learning organization. (3) We might apply and use the CRM techniques of enterprises in SIMS. (4) The SIMS should be easy to make necessary school assessment data. (5) We should complement functions of the SIMS for a lifelong healthcare information management of national human resource. (6) The SIMS should support the school lunch management. (7) We should bring BOM and work-flow concepts into the SIMS.
