A business process specification (BPS) plays the role of a contracted business scenario in the execution of the B2B business process instances. XML-based specification languages, such as BPSS, WS-BPEL, etc., are usually adopted for the specifications. However, composing complex XML-based specifications are not easy for humans. As an alternative, graphical modeling languages such as UML and BPMN can be employed. This paper presents an UML-based modeling method for graphically specifying ebXML BPSS instances (namely, business process specifications). UML diagrams, directly matching with ebXML BPSS, can be reused for understanding and generating ebXML BPSS instances. We discuss the value of tile method by developing a business reference library in the area of supply chain management.

Services in SOA are typically perceived as black-box to service consumers, and can be dynamically evolved at runtime, and run on a number of unknown and heterogeneous environments. Because of these characteristics of the services, effective and efficient monitoring of various aspects on services is an essential functionality for autonomous management of service. But the problem with or limitation in conventional or existing approaches is, that they focus on services themselves, ignoring the effects by business processes. Consequently, there is a room for service monitoring which provides more useful information of business level by acquisition of only external monitoring data that depend on specific BPEL engine and middleware. Moreover, there is a strong demand to present effective methods to reduce monitoring overhead which can degrade quality of services. EDA can cope with such limitations in SOA by collecting and analyzing events efficiently. In this paper, we first describe EDA benefits in service monitoring, and classify monitorring target, and present an appropriate monitoring method for each monitoring target. Also to provide the applicability of our approach, an event meta-model is defined, and event processing model and architecture based on the meta-model are proposed. And, with the proposed architecture and method, we implement a prototype of an event-driven dynamic monitoring framework which can collect and process internal and external data at runtime. Finally, we present the result of a case study to demonstrate the effectiveness and applicability of the proposed approach.

While standardization and its applications for registering and sharing information resources about B2B transactions such as business documents are relatively well developed, it is not easy to register and share business process resources because there are many ways to define complex business processes using different specification(definition) languages. In practice, there are several competing business process specification languages applicable under service-oriented architecture (SOA) such as ebXML BPSS, WS-BPEL, BPMN and so on. A systematic way has to be prepared to register/share diverse and heterogeneous specifications represented using those languages. This paper demonstrates the usefulness of sharing B2B business processes by prototyping a business process registry called ebRR4BP. First of all, we designed a metadata ontology to support the registration of diverse B2B business processes. To implement the proposed metadata ontology using ebXML registries, a mapping scheme to ebXML Registry Information Model is also suggested. The ontology and mapping scheme will be a foundation for supporting common interchange of business process metadata among B2B resistries.

In recent competitive business environment each enterprise has to be agile and flexible. For these purposes run-time monitoring ofservices provided by an enterprise and early decision making through this becomes core competition of the enterprise. In addition, in order to process various innumerable events which are generated on enterprise systems techniques which make filtering of meaningful data are needed. However, the existing study related with this is nothing but discovering of service faults by monitoring depending upon API of BPEL engine or middleware, or is nothing but processing of simple events based on low-level events. Accordingly, there would be limitations to provide useful business information. In this paper, through situation detection an extended complex event model is presented, which is possible to provide more valuable and useful business information. Concretely, first of all an event processing architecture in an enterprise system is proposed, and event meta-model which is suitable to the proposed architecture is going to be defined. Based on the defined meta-model, It is presented that syntax and semantics of constructs in our event processing language including various and progressive event operators, complex event pattern, key, etc. In addition, an event context mechanism is proposed to analyze more delicate events. Finally, through application studies application possibility of this study would be shown and merits of this event model would be present through comparison with other event model.

In recent years, business environments have become more complex; therefore, enterprises must be capable of responding flexibly and agilely. For these purposes, effective enterprise systems service monitoring and early decision making based on the same, emerge as core competency of the enterprise. In addition, enterprise system techniques that filter meaningful data are needed to event processing. However, the existing study related with this is nothing but discovering of service faults by monitoring depending upon API of BPEL engine or middleware, or is nothing but processing of simple events based on low-level events. Accordingly, there would be limitations to provide useful business information. In this study, we present an extended event processing model that enables delivery of more valuable and useful business information through situation detection. Primarily, the event processing architecture in an enterprise system is proposed as a definite approach, and then define an event meta-model suitable for the proposed architecture. Based on the defined model, we propose the syntax and semantics of the elements that make up the event processing language include various and progressive event operators, the rules, complex event pattern, etc. In addition, an event context mechanism is proposed to analyze more delicate events. Finally, the effectiveness and applicability of proposed approach is presented through a case study.

기업은 날이 갈수록 심화되는 경쟁 환경에 대비하기 위해 많은 공급업체들과의 협력관계를 점차 강화해나가고 있다. 정보기술이 발전함에 따라 기업들은 SCM (Supply Chain Management)을 도입하여 이를 실현해나가고 있는 추세이다. 이에 따라, 공급사슬상의 관련 기업간의 상호작용과 정보공유에 기반한 공급사슬 통합이 추진되고 있으며, 정교한 관리를 위해 프로세스 간의 통합을 통해 하나의 글로벌 프로세스로서 SCM을 관리할 필요가 대두되고 있다. 이러한 관점에서 프로세스를 하나의 객체로서 관리하는 BPM (Business Process Management)을 활용하여 SCM을 체계적으로 관리할 필요가 있다. 그러나, 지금까지의 BPM은 비즈니스 프로세스의 자동화 및 통제 등에 주력해왔기 때문에, 전체 프로세스 관점에서 이를 효율적으로 실행하는 기능을 제공하지 못하고 있다. 따라서, BPM을 통해 SCM 프로세스를 단순히 자동화하여 실행한다면, 각 참여 업체들이 글로벌 프로세스의 관점에서 효율적으로 업무를 수행하기 어렵다. 본 논문에서는, 각 공급업체들이 전체 프로세스 관점에서 효율적으로 업무를 수행하는 방법을 제안한다. 제안한 방법을 통해 각 업체들은 전체 프로세스 내 관련 경로의 긴급도 및 관련 업무의 우선처리순위 정보를 제공 받을 수 있다. 따라서, 관련 정보를 토대로 각자의 업무를 수행하기만 하면, 글로벌 SCM 프로세스의 효율성을 향상시킬 수 있을 것이다.

In the real world, business processes are very complex and composed or heterogeneous business activities. As the advent or the Web services enables business processes to be Integrated and to be automated. It makes enterprises integrate heterogeneous business processes from different business partners as well as their internal business processes. To support recent trends in integration of business processes, BPEL, WS-E and WS-T specipications have been established since 2002 WS-C and WS-T describe the reliable business environment including compensation (undo) or completed business processes. The compensation of business processes is a basic requirement for automation or business processes among business partners. Systems implementing these specifications, however, very rarely exist. It's not only because those specifications are developed recently. but also because they are not perfect yet. In this paper, a new business process transaction management, which complements the deficiency of WS-E and WS-T, is suggested. Furthermore, the new approach proposes the business logics for supervisory coordinators which manage serial and parallel business gates The modification or traditional WS-T specification and the simplification or WS-E specification make business processes managed effectively.
