“…In service-oriented automation systems, the research on coordination models (service-oriented engineering in general) is a relatively new area, since the proven concepts of SoA at the device level by the SIRENA project [2]. From the side of process modeling in SoA, research is mainly directed to ebusiness/e-commerce (see [6][7][8]) and even to Petri Nets formalism to describe service-oriented systems [9][10].…”

Abstract-Service-oriented systems constitute a suitable approach for the development of modular, flexible and reconfigurable production systems, addressing the current requirements imposed by global markets. This paper focuses on the process control of Service-oriented production systems, whose behavior is regulated by the coordination of services that are available from distributed modular and collaborative control components. The proposed control is based on a kind of Highlevel Petri Nets tailored for the description, connection and synchronization of different concurrent processes. Several features can be distinguished by this approach, since its modularity, control reusability, flexibility and other valuable inherited characteristics from the proposed High-Level Petri Nets.

“…Prevailing approaches to service composition and service choreography such as [14] [15] [16] primarily compose workflow-based service management systems [17]using WSDL [18] and BPEL [19]. In these approaches, flow constructs are used to define service choreography.…”

“…A WSDL based interface may be defined such that user agents can access the workflow over the network. In [9] and [14], the authors discussed the limitations of BPEL specifications in modeling real world business processes. Our approach adapts and extends workflow technologies to address the unique requirements of the IT service management domain.…”

This paper presents a new approach for the management and engineering of IT-enabled services. Based on the analysis of several real world application scenarios, we propose a "deep structure" for ITenabled service management. We introduce the concept of a business artifact in defining this deep structure. We leverage this deep structure in conjunction with Representational State Transfer (REST) to design and build a platform for service management. Our approach radically simplifies the management and engineering of IT-enabled services and provides a highly flexible and end-user configurable system for service management.

“…To build a composition of services, two steps must be performed (separately or combined) [2]:(1) a composition schema (or a process model) specifying the control and data flows between activities must be created; (2) concrete services have to be discovered and assigned to activities of the process. As regards the degree of dynamicity in these two steps, we have retained two strategies of composition.…”

In recent years, the composition of loosely coupled servies with the aim of satisfying the user intention is a widely followed research topic. The composition of services implies the ability to select, coordinate, interact, and interoperate existing services. This is considered as a complex task. This complexity is mainly due to the large number of available services and their heterogeneity as they are created by different organizations. This complexity is increased when services must be dynamically and automatically composed to meet requirements which are not satisfied by existing services. In fact, an approach for service composition must offer the potential to achieve flexible and adaptable applications, by selecting and combining services based of the request and the context of the user. In this perspective, different approaches have been developed for services composition. However, most of the existing composition approaches tend to be static and not flexible in the sense that they do not have the ability to adapt to user requirements.To overcome these challenges, we propose a composition approach in which the generation of the composition schema is performed at runtime through the use of abstract services provided at design time. The composition process that we propose takes as input a structure of user requirements materialized by a graph of intentions and enriches this graph to explicit the implicit relationships. The enriched graph is used to generate an initial composition schema by building the control flow and selecting the appropriate abstract services. The selection of these services is based on the semantic matching and the degree of semantic affinity between abstract services. Then, the final composition schema is generated using a refinement mechanism of abstract services using semantic matching techniques and taking into account user context and constraints.
