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.     

Business processes oriented heterogeneous systems integration platform for networked enterprises

Supply chains, dynamic alliances, e-business, extended enterprises, and virtual organizations are typical networked enterprises which are formed based on partner companies’ core competencies. Different partners have different infrastructures; the interoperability among heterogeneous systems is the solid foundation for the networked enterprise to work seamlessly and effectively. Due to the distributed and heterogeneous characteristics of different partner companies, it is a big challenge to implement a satisfying and cost effective solution in the networked enterprise.Aiming at the problems of system integration and cross-system interoperability, Service-Oriented Architecture (SOA) provides a new integration pattern and relative system infrastructure. The key for the development and implementation of SOA is services encapsulation and orchestration of applications through certain mechanism to operate a complex business. However, cross infrastructures services access protection and relative services orchestration are still the bottleneck for the SOA implementation.This paper develops a business processes oriented heterogeneous systems integration platform with relative methodology for networked enterprises integration. The platform is a space distributed and management centralized platform for networked enterprises. The service access agent (SAA) mechanism is developed to realize cross-domains identity authentication, service authorization, and information transmission security. Every Web service or SAA in the platform has a unique ID. The interoperating process only relies on IDs, which endows the platform with a loose coupling feature. Aiming at service orchestration, a graphic service process modelling method is developed, with which the developed process model can link atom Web services and form a complex service. The Java based service orchestration tool provides an ESB (Enterprise Service Bus) independent service orchestration and deployment. Those services that are results of orchestration can be orchestrated as an atom service in another orchestrating process. Thus, the platform can support orchestration decomposition. The structure approach of the business process modelling based platform implementation is developed, which provides a guideline for platform installation, services modelling, service encapsulation, service orchestration, and service deployment. Two cases are provided to illustrate the usage of the platform in industries. The development of this platform is an open source project.

Customer order management in service oriented holonic manufacturing

One of the most important problems when considering the design of manufacturing systems based on SOA paradigms is the integration of shop floor devices in the business processes at the enterprise level. This paper presents the design and implementation of the Customer Order Management (COM) module based on SOA architecture in the context of holonic manufacturing systems. The COM module is integrating with SOA enabled shop floor devices using industry standards. The implementation leverages a multi agent system suited for industrial applications integrated in a SOA environment capable of dynamic BPEL workflow generation and execution. The prototype consists in a SCA application for core COM module functionality and an extension for NetLogo MAS platform for SOA integration. The COM module interacts with the MES layer using real time events handled by the BPEL process implementation in the execution stage. A web based portal frontend for the COM module has been developed to allow real time tracking of customer orders, providing data about product batch execution and individual progress of each product on the production line.

Service oriented architectures: approaches,technologies and research issues

Service-oriented architectures (SOA) is an emerging approach that addresses the requirements of loosely coupled, standards-based, and protocol- independent distributed computing. Typically business operations running in an SOA comprise a number of invocations of these different components, often in an event-driven or asynchronous fashion that reflects the underlying business process needs. To build an SOA a highly distributable communications and integration backbone is required. This functionality is provided by the Enterprise Service Bus (ESB) that is an integration platform that utilizes Web services standards to support a wide variety of communications patterns over multiple transport protocols and deliver value-added capabilities for SOA applications. This paper reviews technologies and approaches that unify the principles and concepts of SOA with those of event-based programing. The paper also focuses on the ESB and describes a range of functions that are designed to offer a manageable, standards-based SOA backbone that extends middleware functionality throughout by connecting heterogeneous components and systems and offers integration services. Finally, the paper proposes an approach to extend the conventional SOA to cater for essential ESB requirements that include capabilities such as service orchestration, “intelligent” routing, provisioning, integrity and security of message as well as service management. The layers in this extended SOA, in short xSOA, are used to classify research issues and current research activities.     

信息集成关键技术——企业服务总线

信息化技术和信息化应用的快速发展向企业信息集成提出了更高的要求,以往的EAI已经很难符合企业的需要。在以面向服务架构（SOA）为方向的新的集成方式中,企业服务总线（ESB）是集成的关键技术。ESB包括了通信、消息、安全、管理、集成等多方面的技术和功能。有了ESB的支撑,SOA将以往复杂繁琐的集成系统清晰地分为服务、ESB、业务流程三个主要的层次,并且对遗留系统的集成提供支持。尽管现阶段SOA的应用仍有许多局限,但是随着技术的发展和应用的成熟,ESB终究会成为企业应用的必备软件。     

面向SOA的企业服务总线研究与实现

针对企业日益增长的信息共享和业务整合的需求,面向SOA的企业服务总线屏蔽各类异构的应用从而实现基于SOA架构的企业应用集成是大势所趋。现有的面向SOA的企业服务总线（s-ESB）大多立足于提供Web服务容器,并没有提供统一的适配机制无缝集成各类企业应用,从而极大限制s-ESB的高可用性和可扩展性。首先,提出了一种新型的基于SOA架构的企业应用集成环境,从而明确了s-ESB在构建企业应用集成中的地位和作用;其次,提出了s-ESB的体系结构模型,并解决了协议适配,服务适配和公共服务等关键技术问题;最后,原型系统证明s-ESB的灵活性,可有效集成各类异构企业应用。     

MDA与云计算、SOA的比较研究

云计算能支持符合特定条件的企业或单位,对更多希望获得更好竞争力的企业,云计算不是一个好的选择。基于服务的体系结构((SOA)虽然有助于企业快速实现系统集成,但随着服务数量的增加,用户寻找和使用服务依然是个难题,也不是合适的选择。模型驱动的体系结构(MDA)从方法论和标准方面为企业提供独立于技术实现的商业应用平台,由模型映射的构件以及构件组装与模型库和构件库的管理将会对企业自主信息系统的进化起到极大的支持作用。

基于事件驱动的SOA服务组合技术研究

传统基于Bpel的服务组合方式可以满足业务流程相对稳定的业务需求,但在灵活多变的业务环境中,流程可能会不定时变化,此时需要人工暂停服务、修改流程、生成Bpel文件、重新部署发布等繁琐操作,这显然难以满足快速灵活的业务部署需求。此外,为了支持有人工活动参与的服务,基于Bpel的SOA平台大多采用异步回调来实现,但这种实现手段通常需要保留回调句柄,无形中增加了平台构件之间的耦合性,不符合SOA的基本特性。文章研究了一种基于事件驱动的SOA服务组合方式,通过事件处理引擎驱动服务,并可以通过配置业务规则来实现服务之间组合协作,解决传统基于Bpel组合方式的不足。在此基础上,文章搭建了一个基于事件驱动的SOA平台Swift ED-SOA,并通过应用实例验证了ED-SOA的可行性。
