Information systems development entails planning, analysis, design and construction phases. The analysis phase identifying user requirements is the most important of these phases. Since unidentified defects in the early phase causes increased work and costs as development proceeds, the quality of analysis results affects the quality of the resultant system. Major tasks in the analysis phase are data modeling and process modeling. Research on building a knowledge-based system for data modeling have been conducted much, however, not sufficiently for process modeling. As a system environment with high user interaction increases, research on process modeling methods and knowledge- based systems considering such environment are required. In this research, a process modeling framework for information systems with high user interaction is suggested and a knowledge-based system for supporting the suggested framework is implemented. A proposed model consists of the following tasks: event analysis, process analysis, and event/process interaction analysis. Event analysis identifies business events and their responses. Process analysis break down the processes of an enterprise into progressively increasing details. Decomposition begins at the function level and ends when the elementary process level is reached. Event/process interaction analysis verifies the results of process analysis and event analysis. A knowledge-based system for supporting a proposed process modeling framework is implemented in a web-based environment.

Knowledge-based services are largely dependent upon human-driven works. Therefore, considering human characteristics is required when modeling processes for knowledge-based services. As an emerging technology for Business Process Management, Human Interaction Management and its supportive process management can be an alternative to deal with human-driven processes. However, current HIM does not suggest concrete method for modeling conditions that are essential to realize supportive process management. And the condition modeling of HumanEdj, the only HIM software implemented, reveals the problem of complexity. As a solution, this paper suggests a fact-oriented ontological approach to process modeling. The approach uses human-friendly form of facts for condition modeling.

Proposed in this paper is a standard-compliant business process modeling tool which is based on the UML(Unified Modeling Language) activity diagram and produces an XPDL(XML Process Definition Language) file as an output. The XPDL is a standard process definition exchange format by WfMC (Workflow Management Coalition). To develop an UML/XPDL-based modeling tool, the mapping of modeling elements between activity diagram and XPDL format is conducted after the detailed analysis of each modeling specification. As a result of this mapping, it is revealed that modeling elements of each activity diagram and XPDL must be expanded. So new modeling elements are identified and added to each specification. Based on this mapping, the prototype system is developed, and the usefulness of the developed system is shown through the case study.

In B2B e-commerce environments, many initiatives for process modeling have made efforts to design business processes correctly. Especially, Petri nets have been widely used as a good theory to design and verify process models. Therefore, we propose the process modeling method for the B2B e-commerce based on Petri nets. First of all, a B2B process model based on BPSS is represented by the UML activity diagram. Second, the activity diagram is transformed to a Petri net model. For the transformation, well-behaved building blocks/control structures and the modeling rules for inter-organizational workflow processes are proposed. Third, the process is partitioned into sharable processes for individual business partners. Finally, according to needs of individual business partners, the sharable processes are modified by well-structured refinement rules. The whole procedure is explained with the purchase process of an e-bookstore.

비즈니스 프로세스란 기업의 목표 달성을 위하여 다양한 비즈니스 규칙에 의해 정의된 상호 연관이 있는 비즈니스 기능의 집합을 의미한다. 이러한 비즈니스 프로세스 관리를 위해 많은 기업들은 프로세스 모델링 작업을 수행하게 되는데, 이러한 모델링 작업은 사람에 의해 수행되기 때문에 예기치 못한 이상 현상이 발생할 수 있게 된다. 이러한 이상 현상이 미리 검출되지 않고 프로세스 엔진에 의해 실행된다면 막대한 비용 및 손실을 초래할 수 있기 때문에 모델링 단계에서 이상 현상이 없도록 모델링을 하거나 모델링 도구 자체에서 미리 정의된 이상 현상들을 검출하는 작업이 필요하다. 본 논문에서는 비즈니스프로세스 이상 현상 검출작업에 활용될 수 있도록 모델링 단계에서 발생할 수 있는 이상 현상들을 타입에 따라 분류하고 정의하였다.

The pulsed laser deposition process modeling is investigated using neural networks based on radial basis function networks and multi-layer perceptron. Two input factors are examined with respect to the PL intensity. In order to minimize the joint confidence region of fabrication process with varying the conditions, D-optimal experimental design technique is performed and photoluminescence intensity is characterized by neural networks. The statistical results were then used to verify the fitness of the nonlinear process model. Based on the results, this modeling methodology can be optimized process conditions for pulsed laser deposition process.

Most of companies related to the area of B2B electronic commerce are making their efforts to innovate their existing business process into new designed process. XML-based electronic data interchange has potential to impact on reshaping the traditional EDI systems. This study intends to suggest a prototype of XML-based electronic data interchange using unified modeling language, with a case study applied in Korean automobile industry. In order to accomplish the research objectives, we employed UML as its standard modeling language, In this study, four diagramming techniques such as use case diagram, sequence diagram, class diagram, component diagram among eight modeling techniques are used for analyzing hierarchical business process. As a result of applying UML methodology, we design and develop XML/EDI applications efficiently. Our field test applied to Korean automobile industry shows that data modeling to design XML application using UML is better than existing methodologies in representing object schema of XML data and in extension and interoperability of systems.

업무에 초점을 둔 BPMN 모델은 서비스 지향 비즈니스 모델링에 한계점을 안고 있다. 이에, SOA 기반의 시스템 개발을 위해 서비스 수준에서 복잡한 응용 시스템을 디자인할 수 있는 서비스 지향의 비즈니스 모델링 기법이 요구된다. 본 논문은 BPMN 비즈니스 모델의 모듈성과 재사용성을 향상시키기 위해, 서비스 지향으로 BPMN 모델을 계층적으로 구축할 수 있는 메타모델과 이에 기반한 비즈니스 모델링 프로세스를 제시한다. 이를 위해, BPMN 모델의 모델링 요소들을 MDA와 MVC 패턴에 의해 계층화하고 서비스 지향의 모델링을 위한 확장된 XL-BPMN 메타모델을 정의한다. 이 메타모델의 모델링 요소를 이용해서, 모델링 단계에 의한 BPMN 서비스 모델링 프로세스를 정립한다. 이 기법은 온라인쇼핑몰시스템의 비즈니스 모델링에 사례로서 적용되고 평가되어진다. 잘 정의된 메타모델과 모델링 프로세스를 통해, 서비스 중심의 BPMN 비즈니스 모델을 생성할 수 있고, BPMN 모델의 모듈성을 증진시킬 수 있으며, 또한 독립적으로 재사용 가능한 모델의 수를 극대화할 수 있다.

In this paper, we propose an efficient internet-based logistics brokerage concept which can overcome the weakness of the traditional off-line method to intermediate between vehicle owners and shippers for matching empty vehicles and freights. For defining a business model based on the new concept and implementing an information system, it is necessary to analyze the business process for the internet-based logistics brokerage using a modeling methodology. In this paper, we analyze the logistics brokerage process using the UN/CEFACT Modeling Methodology (UMM) being utilized as a standard modeling methodology in the area of electronic commerce. After analyzing the business process, we can expect that the UMM can be used as a useful tool for modeling the business process of electronic commerce in which the description of the collaborative work is very important.
