ABSTRACT This paper presents an infrastructure and a mechanism for achieving dynamic Inter-enterprise workflow management using e-services provided by collaborative e-business enterprises. E-services are distributed services that can be accessed programmatically on the Internet, using SOAP messages and the HTTP protocol. In this work, we categorize e-services according to their business types and manage them in a UDDI-enabled constraint-based Broker Server. E-service requests are specified in the activities of a process model according to some standardized e-service templates and are bound to the proper service providers at run-time by using a constraint-based, dynamic service binding mechanism. The workflow management system is dynamic in the sense that the actual business organizations, which take part in a business process, are not determined until run-time. We have extended the traditional workflow process modeling by including e-service requests in activity specifications and extended the Web Service Description Language (WSDL) by including constraints in both service specifications and service requests so that the selection of e-service providers can be more accurately performed.

    ABSTRACT: The support for coordination and choreography of independently-developed and locally-managed distributed processes is a key requirement of the emerging business environment in which organizations form, and break, relationships with other organizations on the fly to meet business goals, for example, provide customer and stakeholder value. The current set of Business Process Management Systems do not support this dynamicity of relationships and processes - or process mobility - creating new channels, reassigning channels, in particular, to processes whose existence becomes known only at run-time and may differ by instance. This dynamic nature of the relationships and processes is founded on π-calculus mobility. This paper presents a new approach to implement π-calculus mobility using DIME network architecture; it is shown how process mobility is an inherent capability of DIMEs. This paper also proposes the use of DIME FCAPS capabilities to support business services management, including fault tolerance, performance and security.

    ABSTRACT: Due to the web services' heterogeneous nature, which stems from the definition of several XML-based standards to overcome platform and language dependence, web services have become an emerging and promising technology to design and build complex inter-enterprise business applications out of single web-based software components. To establish the existence of a global component market, in order to enforce extensive software reuse, service composition experienced increasing interest in doing a lot of research effort. This paper discusses the urgent need for service composition, the required technologies to perform service composition. It also presents several different composition strategies, based on some currently existing composition platforms and frameworks, re-presenting first implementations of state-of the-art technologies, and gives an outlook to essential future research work.
