基于语义的业务流程一致性评价

随着Internet技术的不断发展,电子商务中的B2B应用也逐渐成为企业之间进行业务活动的主要依托技术,企业定义了自己的业务流程,双方业务流程的一致性在业务伙伴间的协作中扮演着非常重要的角色。目前,已经有诸如BPEL4WS和ebXML这样的电子商务技术能够使得企业在业务流程级进行协作,但这些技术均是基于XML技术,所提供的功能主要是语法上的,很少涉及他们的业务流程的一致性评价。为此,扩展了ebXML框架以支持业务流程的一致性评价,设计了一个一致性评价代理来执行客户企业的需要,并搜寻ebXML注册中心的潜在伙伴的业务信息,基于良好定义的一致性标准测试他们与客户企业业务流程间的一致性,最后提交一个评价结果给客户企业。通过这样的过程,客户企业能够找到合适的业务伙伴。而且,采用了语义网的方法,使得评价的结果更加准确。     

Message Queuing Markup Language for Enterprise Integration

With the advent of dynamic e-business and its open standards-based supporting technologies, valuable legacy applications that support essential business processes in enterprises can join this new area of distributed computing. Message Queuing allows applications to use components that communicate with one another using queued messages. In this paper, we propose an extensible Message Queuing Markup Language (MQML), which is a major component of the Software Integration Markup Language (SIML) for enterprise integration with Universal Web Services model. A research prototype is presented to validate the effectiveness and value of our proposed MQML for enterprise integration.     

Interoperable enterprise systems: Principles, concepts, and methods

Interoperable enterprise systems (be they supply chains, extended enterprises, or any form of virtual organizations) must be designed, controlled, and appraised from a holistic and systemic point of view. Systems interoperability is a key to enterprise integration, which recommends that the IT architecture and infrastructure be aligned with business process organization and control, themselves designed according to a strategic view expressed in an enterprise architecture. The paper discusses architectures and methods to build interoperable enterprise systems, advocating a mixed service and process orientation, to support synchronous and/or asynchronous operations, both at the business level (business events, business services, business processes) and at the application level (workflow, IT and Web services, application programs).     

A web services-based approach to develop a networked information integration service platform for gear enterprise

In order to deal with the problems of information integration and data sharing across distributed heterogeneous application systems in gear enterprises, it is imperative to build up a high quality information integration platform. Web Services, an emerging form of service-oriented architecture (SOA) for distributed computing, have the potential to serve as a key enabling technology to integrate heterogeneous systems under the distributed environment. This paper presents a novel information integration service platform which offers better support for the networked manufacturing of gear enterprise by taking full advantage of technologies of SOA and Web services. In this paper, the information integrated operation mode of gear enterprise networked manufacturing is deeply analyzed and the functional architecture of the networked information integration service platform is proposed. Furthermore, the application integrated framework of gear enterprise is constructed and the software architecture of the service platform is implemented in the .NET environment. Finally, an actual application example of hypoid gear networked manufacturing is provided to demonstrate the practicability of the proposed platform.     

2005 EDOC: meeting the challenges of enterprise computing

An increasing demand for interoperable applications exists, sparking the real-time exchange of data across borders, applications, and IT platforms. To perform these tasks, enterprise computing now encompasses a new class of groundbreaking technologies such as Web services and service-oriented architecture (SOA); business process integration and management; and middleware support, like that for utility, grid, peer-to-peer, and autonomic computing. Enterprise computing also influences the processes for business modeling, consulting, and service delivery; it affects the design, development, and deployment of software architecture, as well as the monitoring and management of such architecture. As enterprises demand increasing levels of networked information and services to carry out business processes, IT professionals need conferences like EDOC to discuss emerging technologies and issues in enterprise computing. For these reasons, what started out as the Enterprise Distributed Object Computing (EDOC) conference has come to encompass much more than just distributed objects. So this event now used the name International EDOC Enterprise Computing Conference, to recognize this broader scope yet also retain the initial conference's name recognition.     

基于服务协作中间件的动态流程模型

新兴的面向服务体系结构正在加速软件的发展和变化,无法适应动态环境的应用将逐渐失去作用,尤其对那些面临着需求频繁变更的业务流程管理系统而言更是如此.为了响应这种现实需求,基于Web服务和业务流程管理技术,提出了服务协作中间件(service cooperation middleware,简称SCM)模型,探讨了其内部机理与协作流程元模型的形式化.通过引入模型转换,扩充流程状态空间,定义了动态流程模型,动态流程的结构重构和行为自适应可以借助SCM的反射能力得以实现.针对SCM模型,设计了流程虚拟机(prrocess virtual machine,简称PVM),流程在运行时由PVM控制执行.借助于模型驱动机制,业务流程可从设计到运行不断地进行模型变换.由此建立的业务流程能够更灵活、更广泛地适用于各种开放环境,提升企业分布计算.     

Adding intelligent agents to existing EI frameworks

The global marketplace and the Internet have served as catalysts for enterprise integration (EI), both within a company and between a company and its suppliers and partners. EI software architectures, or frameworks, are often built on top of standard middleware and typically lack the ability to function in dynamic environments where flexibility, adaptability, and knowledge management are crucial. Furthermore, they do not scale well to wide-area enterprises that extend across organizational boundaries. These frameworks nevertheless offer a cost-effective basis for resource management, user coordination, knowledge exchange, and information extraction in a virtual enterprise. The paper considers how, by incorporating agents with their inherently distributed characteristics of autonomy, reasoning or intelligence, and goal-driven behavior, existing EI frameworks can be enhanced to support adaptive virtual enterprises

Model-based services convergence and multi-clouds integration

With the development of cloud computing, IT users (individuals, enterprises and even public services providers) are transferring their jobs or businesses to public online services provided by professional information service companies. These information service companies provide applications as public resources to support the business operation of their customers. However, no cloud computing service vendor (CCSV) can satisfy the full functional information system requirements of its customers. As a result, its customers often have to simultaneously use services distributed in different clouds and do some connectivity jobs manually. Services convergence and multi-clouds integration will lead to new business models and trigger new integration technologies that provide solutions to satisfy IT users’ complicated requirements. This paper firstly reviews the development of cloud computing from business and technical viewpoints and then discusses requirements and challenges of services convergence and multi-clouds integrations. Thirdly, a model based architecture of multi-clouds integration is provided. Business logic modelling for cross-organizational collaboration, service modelling and operation modelling methods with relative model mapping technology are discussed in detail. Some key enabling technologies are also developed. At last, case studies are presented to illustrate the implementation of the technologies developed in the paper.

Supporting virtual enterprise systems using agent coordination

Open environments like the Internet or corporate intranets enable a large number of interested enterprises to access, filter, process and present information on an as-needed basis. These environments support modern applications, such as virtual enterprises and interorganisational workflow management systems, which involve a number of heterogeneous resources, services and processes. However, any execution of a virtual enterprise system would yield to disjoining and error-prone behaviour without appropriate techniques to coordinate the various business processes. This paper reports on the design and implementation of a flexible agent-based framework for supporting the coordination of virtual enterprises and workflow management systems. The paper also shows how an agent coordination infrastructure, which is explained by social constraints, can impact on the engineering of highly dynamic virtual enterprises and workflow management systems by presenting a simple case study.     

A TCPN based approach to model the coordination in virtual manufacturing organizations☆

The recent developments of communication technologies and network computing have enabled the occurrence of the advanced manufacturing strategy—agile manufacturing. The essence of the agile manufacturing strategy is to form a virtual manufacturing organization (VMO), which integrates the core competencies of member enterprises in order to respond to the global market and increasing customer requirements rapidly. In a VMO, the manufacturing processes are distributed. So modeling and coordination of these processes are very complex. In this paper, we present a Petri Net based approach to model these distributed manufacturing processes and interaction relations among them. A workflow based manufacturing process execution environment is also established to support the implementation of the distributed manufacturing processes.     

Sustaining interoperability of networked liquid-sensing enterprises: A complex systems perspective

The emerging Liquid-Sensing Enterprise (LSE) concept provides manufacturing industrial networks with the required enablers to seamless interoperate and sustain its interoperability along the operational life cycle. Actually, the actual domain of enterprise information systems interoperability prospects the need for a new paradigm able to manage the network dynamics, facilitating adaptation along the lifecycle of an enterprise and the LSE network. The theory of complex systems provides a set of heuristics that can be applied to support the formalization of the LSE industrial network and its dynamics, demonstrating how they can be enabled and at the same time controlled to keep the overall level of interoperability stable. Hence, today there is technology suitable to implement such systems, capable to realize the LSE real, digital and virtual worlds. However, isolated, this technology cannot deliver the requirements for a self-sustainable LSE network. The authors propose a novel metaphor from complexity as a framework to model and implement the mechanism for sustaining interoperability in such networked environments. They identify the motivations for sustaining interoperability of networked liquid-sensing enterprises, having complex and adaptive systems as a vehicle to model and understand the relationships between enterprises and enterprise information systems in networked environments. Then, existing technology such as model-driven interoperability, agent-based or service oriented architectures, and knowledge management, is proposed to detail the conceptual solution for the sustainability of interoperability. An instantiation of the concept proposed is presented, which details the prototypal application elaborated in a real manufacturing scenario, implemented and validated during the European Project Factories of the Future IMAGINE.     

Mighty MESs; state-of-the-art and future manufacturing execution systems

This article intends to answer what manufacturing execution systems (MES) are and describe their relationship with other information systems. It summarizes the features of those significant MESs being used today and discusses their limitations and where they should evolve in order to accommodate customer needs for faster real-time response, the expanded functionality, and increased complexity, as well as computing technologies and research areas that support such evolution. The main message is that it is essential for a semiconductor manufacturer to invest into advanced MESs to keep them competitive in the severely intensified global marketplace. As an MES is deployed on the shop floor in a manufacturing enterprise, the manufacturing process becomes information driven, contributing to both overall productivity and the financial viability of the manufacturing enterprise. Lastly, recognizing that MES deployments are not restricted to the semiconductor industry, the advancements could be applied with little or no refinement to other automated manufacturing environments.     

An overview of workflow management: From process modeling to workflow automation infrastructure

Today's business enterprises must deal with global competition, reduce the cost of doing business, and rapidly develop new services and products. To address these requirements enterprises must constantly reconsider and optimize the way they do business and change their information systems and applications to support evolving business processes. Workflow technology facilitates these by providing methodologies and software to support (i) business process modeling to capture business processes as workflow specifications, (ii) business process reengineering to optimize specified processes, and (iii) workflow automation to generate workflow implementations from workflow specifications. This paper provides a high-level overview of the current workflow management methodologies and software products. In addition, we discuss the infrastructure technologies that can address the limitations of current commercial workflow technology and extend the scope and mission of workflow management systems to support increased workflow automation in complex real-world environments involving heterogeneous, autonomous, and distributed information systems. In particular, we discuss how distributed object management and customized transaction management can support further advances in the commercial state of the art in this area.
