This paper outlines opportunities and challenges in the implementation of BPEL based WFMS(WorkFlow Management System) for the MES(Manufacturing Execution Systems) in semiconductor manufacturing. At present, the most MESs in semiconductor wafer fabrication shop have the problems in terms of application software integration, reactivity, and adaptability. When a plant has to produce new product mix, remodel the manufacturing execution process, or replace obsolete equipments, the principal road blocks for responding to new manufacturing environment are the difficulties in porting existing application software to new configurations. In this paper, the issues about WFMS technologies including BPEL standard applied for MES are presented. And then, we introduce the integrated development framework named nanoFlow which is optimized for developing the BPEL based WFMS application for automated manufacturing system. And we describe a WFMS implemented with using nanoFlow framework, review and evaluate the system.

고객과 공급업체 그리고 비즈니스 파트너들 간의 협업과 정보 공유를 수행하는 일련의 비즈니스 프로세스(Business Process)는 전자상거래에서 흔히 찾아 볼 수 있으며, 이는 Wf-XML을 기반으로 하고 있다. Wf-XML(workflow-XML)은 비동기 웹서비스 프로토콜로 워크플로 엔진의 상호연동을 위해 제안된 XML기반 프로토콜을 정의한 언어이다. 본 논문에서는 서로 다른 워크플로 엔진의 상호연동을 위하여 Wf-XML에서 제공하는 리소스 모델을 UML 다이어그램으로 모델링하여 기업들간의 상호연동과 협업을 위한 업무 흐름 파악을 용이하게 하는 모델을 제안한다.

In producing anamorphic 3D advertisement projects, it is necessary to apply the principles of illusion art to distort the images output to the screen (Image Distortion) so that their display aligns with our visual perception in a real three-dimensional environment. We focuse on the methods of image distortion in the creation of content for anamorphic 3D advertisement screens in this thesis. We propose using Unity 3D's real-time rendering instead of the offline rendering method of compositing method, and employing UV grid mapping to replace the manual correction in Adobe After Effects(AE). The significance of this paper lies in simplifying the image distortion processing workflow in anamorphic 3D projects and optimizing the image distortion creation methods used in compositing method. In outdoor anamorphic 3D advertisement projects, the proposed image distortion creation method demonstrates significant advantages in terms of production time, process simplification, flexibility, and expansion possibilities. Our research provides new perspectives and methods for the creation of anamorphic 3D content, offering theoretical and methodological references for professionals working on similar contents.

비즈니스 프로세스 관리(BPM)는 프로세스의 모델링, 분석, 실행에 이르는 비즈니스 프로세스 전 라이프 사이클을 지원하고자 하는 개념으로, 급변하는 경영 환경의 변화에서 기업의 경쟁력을 재고하기 위하여 필요로 되는 새로운 기업 컴퓨팅 패러다임이다. 비즈니스 프로세스 관리의 개념을 도입함으로써 기업들은 조직의 프로세스를 능동적이고 빠르게 (재)설계하고 수행할 수 있으며, 기업간 M&A 및 전략적 제휴를 효율적으로 수행할 수 있다. 기업간 협업이 이루어지기 위해서는 그들 간의 프로세스의 교류 및 통합이 필수적이다. 통합의 한 수단으로 여러 프로세스에 관련된 Data들을 Rule의 형태로 표현하여 관리할 수 있다. 본 연구에서는 워크플로, BPMS 등의 환경에서 비즈니스 Rule을 포함하는 비즈니스 프로세스 수행시에 관리해야 할 제약조건을 통합 관리할 수 있는 방법론을 제시한다. 비즈니스 프로세스를 수행하면서 체크해야 할 제약조건들을 규명한후 이들을 표현할 수 있는 프로세스 기반의 트리거 모델을 제시한다. 또한 본 방법론의 실현 가능성을 보여주기 위해 예제와 함께 프로토타입 시스템을 구현하였고 Performance 측면에서는 제한적이기는 하지만 DB에 기반한 제약조건 관리방법과의 비교를 통해서 본 연구에서 제안하고 있는 방법의 우수성을 보여준다. 본 연구에서 제안하는 방법론은 Workflow 및 BPMS와 같은 프로세스 관리 시스템에서 통합의 수단으로 사용되고 있는 EAI 등을 보완해 줄수 있는 툴로써 활용가능하리라 기대된다.

BPMN(Business Process Modeling Notation)은 BPMI(Business Process Management Initiative)에서 발표한 것으로서 비즈니스 프로세스 모델링을 위한 표준 표기법이다. BPMN은 표준 모델링 표기법 이므로 다른 모델링 표기법을 익히는데 사용되는 시간을 줄이며 IT 및 비즈니스 사용자들 간의 의사소통을 증진시킬 수 있다. 이에 대응하여 WfMC(The Workflow Management Coalition)는 XPDL 매핑작업을 시도하여 BPMN을 XPDL로 표현할 수 있도록 하였고, 그 결과 BPMN에 매핑시킨 XPDL2.0을 발표하였다. 본 논문에서 설계한 모델링 시스템은 표준 표기법인 BPMN을 통하여 모델링을 하고 그 결과를 국제 표준화 워크풀로우 정의 언어인 XPDL2.0으로 제공하는 워크플로우 모델링시스템을 제안하여 다른 워크플로우 시스템들과의 상호 호환성을 제공하는 것이며, 역할 기반의 모델링 방식으로 복잡한 모델링 작업을 단순화 시킬 수 있다. 즉, 워크플로우 모델링 기능에 실시간 그룹웨어 특성들을 통합하여, 한 차원 높은 수준의 모델링 환경제공을 통하여 기존의 워크플로우 시스템들이 지원하지 못 했던 워크플로우 모델링 협동 작업을 실시간으로 지원 할 수 있을 문만 아니라, 요즘과 같이 대형화와 복잡화 그리고 다양화의 특징을 갖는 조직들의 워크플로우 들에 대한 효율적인 분석 및 모델링 환경을 제공하기 위한 워크플로우 모델링 시스템을 제안한다.

This paper outlines opportunities and challenges in the Implementation of BPEL based WFMS(Work Flow Management System) for the MES(Manufacturing Execution Systems) level in semiconductor manufacturing. At present, the most MES that are composed of several hundreds of applications in semiconductor wafer fabrication shop have the same problems as others about flexibility and adaptability. When a plant has to produce new product mix, remodel the manufacturing execution process, or replace obsolete equipments, the principal road blocks for responding to new manufacturing environment are inflexible communication infrastructure among the manufacturing process components and the difficulty in porting existing application software to new configurations. In this paper, the issues about BPEL standard, used for the flexibility of Workflow Management System, are presented. We introduce the integrated development framework named nanoFlow which is optimized for developing the BPEL based WFMS application for automated manufacturing system. We describe a WFMS implemented with using nanoFlow framework, review and evaluate the system in terms of flexibility and adaptability.

This paper introduces the development of an integrated design system using Service-Oriented Architecture. The system is proposed and being developed based on several advanced technologies, such as multi-agents, Internet/web Service, workflow, database and is aiming to provide the successful fulfill our target of integrating personnel, design activities and engineering resources along a predefined engineering design project (workflow) during product development process. By using SOA concept, the system tries to separates the engineering process into the engineering knowledge and the usage of engineering tool. Consequently, the computing resources in organization can be fully utilized and thus the cost can be reduced. The system is being designed and developed on the base of JADE (Java Agent DEvelopment Framework).

The process and efficiency of monitoring building and construction violations is a concern of the construction industry. The detection of violations requires appropriate and sufficiently accurate spatial information to manage and support a comprehensive inspection process and monitor compliance. A building inspection workflow must extract appropriate spatial and measurement in-formation from a variety of sources, identify potential violations across a range of compliance criteria and determine the quality of resulting inspection reports. This paper presents a framework for supporting building inspections using spatial information and methods to detect construction violations and compliance. Current inspection processes involve issues around the identification of building violations, access to building regulations and existing spatial information, integration of a range of spatial and non-spatial information, and the quality of decisions within the inspection workflows. A survey of building inspectors was conducted and used together with the issues identified to establish the requirements for a spatial inspection framework. The results demonstrate how such a framework can support improved decision-making and reduced fieldwork effort in detecting and measuring the accuracy of building violations involving building placements, street offsets and footprint areas.

Process mining aims at mining valuable information from process execution results (called "event logs"). Even though process mining techniques have proven to be a valuable tool, the mining results from real process logs are usually too complex to interpret. The main cause that leads to complex models is the diversity of process logs. To address this issue, this paper proposes a trace clustering approach that splits a process log into homogeneous subsets and applies existing process mining techniques to each subset. Based on log profiles from a process log, the approach uses existing clustering techniques to derive clusters. Our approach are implemented in ProM framework. To illustrate this, a real-life case study is also presented.

Traditional business process management systems provide verification tools of process models to deploy and automate the models. However, there are not so many studies on how to maintain systematically collaborative process models such as supply chain processes when companies are willing to change and update the collaborative process models. In this paper, we analyze change patterns of collaborative processes and declare 19 change patterns. In addition, we apply the change patterns to the process interoperability patterns in order to identify the change problems in case of independent process changes of collaborative processes. As a result, we devise an independency checking algorithm of process changes in collaborative processes.
