基于CCSOA的服务供应链研究

当前的SOA主要是以服务提供者为中心的,因此,对于个性比较特殊的服务需求,采用目前的SOA,服务使用者很难找到符合要求的服务.介绍了一种新的SOA形式--以服务使用者为中心的SOA,简称CCSOA.在此架构中,服务使用者将服务甚至应用需求说明发布到服务注册中心,服务提供者浏览应用需求来提供相应的服务.接着,从电子商务的角度出发,结合CCSOA,提出了一种服务供应链结构,且对该平台下关于服务的操作进行了探讨.     

一种基于服务需求的自动测试数据生成方法

以服务消费者为中心的CCSOA架构支持服务需求的发布和针对服务需求的开发.验证所开发服务是否满足服务需求是一个必须解决的问题.本文提出一种以服务需求的合约文档描述为基础自动生成测试数据的方法,用于解决CCSOA架构下服务自动测试的问题.服务需求的描述在WSDL语言基础上进行扩展,增加服务需求的合约化描述.通过正则表达式描述合约,在合约中嵌入测试支持元素.通过对服务需求合约文档的解析,自动构建针对合约文档的有限状态自动机,生成测试数据.通过实验分析,验证了方法的可行性.

基于区块链的可信SOA架构

在传统服务架构(Service-Oriented Architecture, SOA)中，Web Service提供者将其服务描述注册在注册中心，供服务消费者进行服务发现和服务调用。尽管该架构可以提供松散的服务调用，但是缺乏争议解决机制，使得互不信任的服务消费者和提供者之间的服务可信调用得不到保证。区块链技术在去中心化和抗篡改等方面具有显著的优势，可被合理地应用在传统SOA中，以解决服务可信问题。结合传统SOA架构和区块链技术，提出了一种基于区块链的可信SOA架构，实现可信的服务调用。在一次服务可信调用过程中，服务消费者进行参数加密并将其发送给目标服务提供者；服务提供者接收加密参数并对其完成解密；服务提供者完成服务执行并对输出结果完成加密；最后服务提供者在将加密结果发送给服务消费者的同时完成可信凭证的构造与上链。在上述基础上，当发生服务纠纷时，将触发裁决智能合约，正确处理服务纠纷。实验结果表明，与传统的调用相比，所提方法能够在保证大部分服务可信调用时间增长率不大于30%的前提下，正确处理服务提供者和请求者之间的服务纠纷。     

华胜天成：SOA也轻量级

“SOA是一种IT体系结构样式,支持将客户的业务或系统功能点封装成为可重复调用的服务进行集成,并可以随时随地的通过网络访问或调用这些服务以实现其业务需求。SOA的优势之一说起来就应该是做应用集成了,我们已经为客户做了很多基于SOA架构的应用集成项目,比如南京油运的SOA项目和邮政的物流系统的SOA项目等等。公司自己内部的应用集成也用了SOA架构。”北京华胜天成科技股份有限公司的首席信息官陈其伟说。

Web service-oriented manufacturing resource applications for networked product development

Networked manufacturing enterprises need a wider support from external manufacturing resources. This paper proposes a promising service to use web-based extended manufacturing resources for product development. The system architecture and enabling techniques are presented. Manufacturing resources on the web are achieved through focused crawling and semantic web technologies. These resources are further utilized through web-based resource repositories such as part libraries. The major modules of web-based manufacturing resource service are encapsulated with web services. A case study of mould product development is presented, which promotes the networked collaborative design and manufacturing processes. Some preliminary results indicate the feasibility and scalability of web-based manufacturing resource services for networked manufacturing.     

Federated integration of networked manufacturing service platforms

Networked manufacturing is an advanced manufacturing pattern that was born of information technologies and suits the networked economic environment. Networked manufacturing service platforms have been widely established to support this new pattern. Since the island problems are retarding further development of networked manufacturing, integration of existing networked manufacturing platforms is in demand. A federated integration mode is proposed to integrate the existing networked manufacturing platforms and provide a large-scale distributed resource sharing and cooperative environment. The nature of federated integration is discussed, and the architecture of federated integration system was put forward along with a set of rules and three types of integration services. Two key issues in federated integration are discussed in detail. One is the federation management, including the hierarchy of federations, the basic states of federations and the state-keeping mechanism using factory/instance pattern. The other issue is the authentication, authorization and access control in across-platform applications. Finally, an implementation is presented.

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.

A hybrid multi-agent system architecture for enterprise integration using computer networks

The manufacturing industries are now experiencing fierce pressure of competition from every corner on this planet. In addition, the advancement in computer networks and information technologies has been gradually reshaping the manufacturing companies by shifting from the industrial age to the information era. Due to these elevated competitiveness and advanced computer technology, a number of new manufacturing and management strategies (e.g., CE or CIM) have emerged for the innovation of manufacturing enterprises. Although they have different definitions and scopes, there are several common issues: inter-enterprise functions integration; inter-enterprise resources integration; and collaboration. This paper proposes a new multi-agent system (MAS) architecture to support the inter-enterprise functions/resources integration and collaboration over the networked environment, including the hybrid agent architecture and hybrid network architecture. In contrast to the existing agent architectures, the proposed agent architecture enables agents to exhibit the hybrid (continuous and discrete) behavior and interactions. In addition, our network architecture is more suitable for building the large-scale distributed manufacturing systems that are prone to dynamic random changes of their environment. Based on the proposed MAS architecture, a collaborative product development environment is implemented as a starting point, and a multidisciplinary team-oriented design problem is illustrated to provide the vision of the proposed MAS architecture.
