ContextThe project will investigate the design techniques applicable in a collaborative business environment, andproduce a methodology and a tool supporting the e-services design process. Business fields characterizedby collective activities are numerous and require well-adapted software-based services to improve theefficiency of business collaborations. In the Luxembourg construction sector, innovative cooperationservices have been developed in the MCESR Build-IT project. In the Architecture, Engineering andConstruction sector (AEC), existing services are dedicated to both collective activity support and internalmanagement of organizations. An important challenge in modeling these heterogeneous services is toallow the users composing them to answer specific requirements of a collaborative project.Research issuesThe complexity of exchanges and the number of actors involved in collaborative activities requiremodeling the business context in which e-services are deployed, describing both the consuming and therealization processes. We thus propose to base the project on the outcomes of the FNR Efficient project:the methodology and toolset produced to design and validate e-business transactions will be transformedfrom a message-oriented to a services-oriented paradigm. Integrating the concept of business service (asabstraction of a business process, as consumed by business processes, as composed of software-basedservices) will extend the capabilities of the tool to model and validate service-based businesstransactions.Scientific approachThe design methodology will address both the functional and non-functional perspectives. The mainchallenges in the functional description of the services are defining the right level of abstraction on theprocess description, and adding semantics to the existing syntactical description languages. A metamodelof collaborative projects, developed with the MAP-CRAI laboratory, will be reused to defineinitial business domains. The non-functional aspects (NFA) of the service are required to specify theQuality of Service and establish Service Level Agreements. NFAs are added to the service-basedtransaction model to link them with business level objectives. After a preliminary state of the art, thesetheoretical perspectives will be validated in the AEC domain. A multidisciplinary research team,including a PhD from the construction sector, will support the scientific approach.Expected results- A methodology and a tool to design and validate e-services.- Specific models of collaborative processes, and a guide assisting the actors in composing the servicesadapted to their specificities.- Sectorial service repository stimulating business collaborations and supporting negotiations of SLA- Contribution to the international recognition of the CITI department in Services Science, especiallythrough transaction modeling to support the vision of sectorial service-driven innovation- A cooperation with the CRP – Gabriel Lippmann regarding the deployment of the designed servicesinto an open source SOA framework.
