“…We have previously suggested the concept of a service goal to characterize the possible achievements of a service, and have shown how service goals can simplify service modeling in UML2 [4]. This article refines the semantics of service goals, which is one result of the EU IST project SIMS 1 .…”

“…1. One can ask for available rooms at specific dates, and either reserve the room and thus achieve the goal RoomReserved 4 , or take an option on that room and achieve the goal OptionOnRoom. A <<goal>> state has exactly one outgoing transition, stereotyped <<transitionGoal>>: this transition is instantaneous.…”

“…Moreover, activity diagrams are in line with the semantics of goal sequences: each activity represents a goal to be achieved. Sanders proposed interaction overview diagrams for goal sequences [4,7]; however such diagrams currently lack tool support. We investigated using state diagrams in [11], which have more tool support, but they tend to get cluttered up when expressing parallel behavior in orthogonal states.…”

Abstract. Services are normally not performed by a single component, but result from the collaboration of several distributed components. Their precise specification and validation require complex models, where the intention of the service is easily lost in the detail. This paper exploits the concept of service goals that was earlier introduced to simplify service modeling. It describes the semantics of service goals, how to specify and how to use them. We show that so-called goal sequences can provide a designer-friendly, high-level description of the intention of the service, while maintaining simplicity, reusability and flexibility when composing from elementary services. By way of examples, we illustrate the difference between goal sequences and behavior descriptions. Finally we discuss issues related to the validation of goal sequences and their use at design time and runtime, for example in connection with service discovery.

“…The use of collaborations for the modeling of services [13,14], the use of class diagrams for the structure and graph transformations for the behavior modeling [15,16], and a formal model of ensembles [17] have been proposed. However, none of these approaches supports the construction of dynamic collaborations as required for smart SoS where systems dynamically join or leave the federation.…”

Abstract. Systems of Systems (SoS) have started to emerge as a consequence of the general trend toward the integration of beforehand isolated systems. To unleash the full potential, the contained systems must be able to operate as elements in open, dynamic, and deviating SoS architectures and to adapt to open and dynamic contexts while being developed, operated, evolved, and governed independently. We name the resulting advanced SoS to be smart as they must be self-adaptive at the level of the individual systems and self-organizing at the SoS level to cope with the emergent behavior at that level. In this paper we analyze the open challenges for the envisioned smart SoS. In addition, we discuss our ideas for tackling this vision with our SMARTSOS approach that employs open and adaptive collaborations and models at runtime. In particular, we focus on preliminary ideas for the construction and assurance of smart SoS.

A b s t r a c t Many services are provided by a structure of service components that are dynamically bound and performed by system components. Service modularity requires that service components can be developed separately, deployed dynamically and then used to provide situated services without undesirable service interactions. In this paper we introduce a two-dimensional approach where service components are roles defined using UML 2.0 collaborations and system components are agents representing domain entities such as users and terminals. The process of dynamic role binding takes place during service execution and provides general mechanisms to handle context dependency, personalisation, resource limitations and compatibility validation. A policy framework for these mechanisms is outlined.
