Demand of Natural Gas (NG) consumption is continuously increasing by long service life and low environmental impact than other fossil fuels. Because of this reasons, Gas wells exploration and huge LNG plant construction project are being boosted world-widely. Especially, overseas NG pipe-line projects are emerging by considering safe and efficiency at the inter-country sections. At the same time, Korean contractors are being achieved to record-breaking performance at 2011's overseas construction market and 80% of new-record was attained from overseas plant construction projects. Nevertheless, Korean contractors are behind than overseas leading contractors by geographical distance from gas wells and concentrated demand for storage plant. In these reasons, this paper aims to develop the standardized business process model(BPM) for overseas NG pipe-line project at project planning phase to support the project entry. To this aim, first of all, extract the BPM through the broad literature and overseas construction market review and domestic/overseas pipe-line project analysis. Second, Test-bed was performed to confirm of practical applicability by 4 experts. And then 15 experts survey were performed to validate the usability and effectiveness of BPM for overseas NG pipe-line project. Consequently, if Korean contractors are using this BPM with their own know-how and experiences, it will be returned to more reasonable and rational references for decision making in overseas NG pipe-line project.

This research focuses on the process improvement of port logistics by using Lean methodology. On the one hand, we firstly analyze the current situation and weakness of the processes in port logistics, and then re-design the current processes by the principles of Lean discipline. Based on the appropriately changed processes, the improvement scheme of port logistics will be figured out. On the other hand, we construct the port logistics system by implementing the improved processes. The port logistics' processes accomplished in steel company will be further assorted and identified. The relationship of wharves process, operational process, shipping process, construction process, quality process, and purchasing process are also defined. Every process has been improved by Lean Tools in order to analyze the value added or non-value added processes, to improve the service level, and to reduce the cycle time, inventory, changing time, re-working and waste. Based on above, the appropriate environment that is suitable to Lean process of port logistics will be established and the modeling that can help to implement the improvement scheme will be figured out.

Business Process Management (BPM) System is a software system to support an efficient execution, control and management of business processes. The system automates complex business processes and manages them effectively to raise productivity. Traditional commercial systems mainly focus on automating processes and do not have methods for enhancing process performances and task performer's efficiency. Therefore, there is room for enhancement of task performers' productivities and efficiency of business processes. In this paper, we propose a new method of executing business processes more efficiently in that a whole process is scheduled considering the degree of participants' workload. The method allows managing the largest constraints among constituent resources of the process. This method is based on the DBR (Drum-Buffer-Rope) in TOC (Theory of Constraints) concepts. We first consider the differences between business process models and DBR application models, and then develop the modified drum, buffer and rope. This leads us to develop BP-DBR (Business Process-DBR) that can control the proper size of task performers' work list and arrival rate of process instances. Use of BP-DBR improves the efficiency of the whole process as well as participants' working condition. We then carry out a set of simulation experiments and compare the effectiveness of our approach with that of the scheduling techniques used in existing systems.

인터넷을 이용한 기업간 전자상거래를 위해 기업 내부의 업무 흐름을 관리하는 워크플로우에 관한 관심이 높아지고 있다. 워크플로우 엔진을 구동시키기 위해 먼저 고려되어야 하는 것이 기업 내부의 업무 프로세스를 정의하고 정의된 프로세스를 validation할 수 있는 모델링 도구가 필요하다. 이에 본 논문에서는 물류 협업 프로세스를 정의하고 모델링하기 위한 EJB 기반의 Business Process Modeling Tool(BPMT)를 설계 및 구현하다. BPMT는 WPDL을 지원하는 다 기종의 워크플로우 엔진에서도 협력 체제를 구축할 수 있도록 설계되었으며, 프로세스를 수행시키기 위한 Activity, Transition, Process, Organization, Application, RelevantData DataType으로 구성 되는 일련의 업무 흐름을 정의하며, 범용적인 의미의 Process 설계 도구로서 사용자가 편리하게 작업할 수 있도록 Integrated UI를 지 원한다. 또한 기본적인 물류 영역의 업무 프로세스를 라이브러리화하여 제공함으로써 사용자로 하여금 새로운 물류 프로세스 정의를 쉽게 한다.

USN (Ubiquitous Sensor Network)의 인프라 기술은 유비쿼터스 환경에서의 다양한 서비스를 창출하고 실생활에 적용할 수 있는 기술로 정착하고 있다. 산업분야에서는 관계적 협업이 중시되는 비즈니스 환경에서 실시간 기업이 되기 위해 RFID, EPC 네트워크 등의 기술을 비즈니스 서비스 모델에 적용한 u-SCM으로 적용할 수 있다. 웹 서비스 환경에서 u-SCM을 적용하면서도 고차원의 공급사슬 통합이 이루어지기 위해서는, 여러 상호작용주체가 참여하는 글로벌 프로세스 수준에서 u-SCM프로세스를 관리하고 제어할 필요가 있으며, 본 논문에서는 유비쿼터스 컴퓨팅 기술을 SCM에 적용한 u-SCM 프로세스를, 비즈니스 프로세스 표준언어인 BPEL(Business Process Execution Language)을 적용하여, 각 업무프로세스를 웹서비스로 구성된 환경에서 효과적으로 통합하여 적용하도록 하는 방안을 제시한다. 이러한 접근법은 기업, 조직 간에 적재적소에 실시간 데이터를 수집하고 접근 및 분석하여, 업무 프로세스의 중단이 없도록 u-SCM 프로세스의 진행과정을 보다 효율적으로 관리, 모니터링 하는 것이 가능하도록 하며, 향후 u-SCM프로세스 수행 결과를 토대로 프로세스의 개선에 대한 방안을 모색할 수 있다.

Abstract Corporate activities are composed of numerous working processes and during the working flow, various business processes are being created and completed simultaneously. Enterprise Resources Planning (ERP) makes the working process simple, yet creates more complicated work structure and therefore, there is an absolute need of efficient management for business processes. The workflow literature has been looking for efficient and effective ways of rediscovering and mining workflow intelligence and knowledge from their enactment histories and event logs. As part of studies to analyze and improve the process, the concepts of 'Process Mining', 'Process re-discovery', 'BPR (Business Process Reengineering)' have appeared and the studies for practical implementation are proactively being done. However, these studies normally follow the approach throughout data warehousing for log data of process instances. It is very hard for these approaches to reflect user's intention to the rediscovering and mining activities. The process instances designed based on the consideration of analysis can make groupings effectively and when the analysis demand of user changes within the analysis domain can also reduce the cost of analysis. Therefore, the thesis proposes a special type of workflow model, which is called a colored workflow model, that is extended from the ICN (information control net) modeling methodology by reinforcing the concept of colored token. The colored tokens represent the conceptual types of constraints and criteria that can be used to classifying and grouping the workflow intelligence and knowledge extracted from the corresponding workflow models' enactment histories and event logs. Through the runtime information of process instances, it makes possible to analyze proactive and user-oriented process with the goal of deriving business knowledge from the beginning of process definition.

기업의 경쟁력을 확보하고, 이를 유지하기 위해서는 기업의 정보화가 필수적이다. 이에 따라 구현된 한 기업의 정보화 수준을 평가할 수 있는 정보화 수준 평가모델은 매우 중요한 척도로 사용된다. 그러나 기존의 평가방식들은 대부분 중소기업의 다양한 규모와 업종, 사업유형 등을 반영하지 못하고 있을 뿐만 아니라, 기업의 주요 업무프로세스별로 현재 상황의 정보화 수준을 평가해서 향후 정보화를 추진하기 위한 로드맵을 제시하는데 한계가 있다. 본 연구에서는 중소 제조업체를 대상으로 제조업종의 사업형태를 고려하여 전사적 정보화 성숙단계 및 주요 업무프로세스별 정보화 수준을 평가할 수 있는 모델을 개발하였다.

The processes for verification of performance records in construction have many problems according to construction firm's participating in some of the processes. This study analyzed about current processes and provided improved processes with IDEF method. As the result of this study, it was found that 'As-Is' model has many repetition of activities and 'To-Be' model has three times more effective than 'As-Is' model has. The data modeling which is available for 'To-Be' model was also suggested.
