Adaptable Coordinated Service Compositions (WP-JRA-2.2)

Objectives

The main objective of this workpackage is to investigate various aspects of composition and coordination of composite services in order to provide the mechanisms and technological underpinning for adaptable service-enabled business processes in multiple domains.

This will fill in the gap left by the existing work in the area of service composition and coordination and address open research issues in a structured and unified manner through the convergence of the expertise of the beneficiaries. We aim at providing both top-down and bottom-up approaches for creating coordinated service compositions, taking into account the needs of all stakeholders involved, including QoS characteristics of processes and also KPIs.

These methods will be influenced by the business processes the business partners (i.e. stakeholders) need to implement. The work on the workpackage will comply with the requirements imposed by the generic principles of service based engineering and the adaptation framework.

All the mechanisms and technologies will be provided as capabilities to the JRA-1 and will be used as realisation of the adaptation strategies and design specifications specified by WP-JRA-1.1 and WP-JRA-1.2.
We will define mechanism and models, and enable model and language support for composing and coordinating service compositions also on the basis of their behavioural characteristics and QoS features.
We will define mechanisms for resolving conflicts among system level coordination protocols and enable support for service compositions compliant to both their local protocol implementations and to global coordination protocols.
We will improve existingmethods for service matchmaking based on their QoS, by enhancing them with approaches taking KPIs and behavioural features into account. These methods are necessary for enabling adaptable service compositions on the technological level.
We will set the foundations of a technology for adaptable and self-configuring service compositions as well as the definition of methods for composing services based on their QoS capabilities and business level requirements, behavioural features.
