Structure and Behaviour of Virtual Organisation Breeding Environments
This paper provides an outline of a formal approach that we are developing
for modelling Virtual Organisations (VOs) and their Breeding Environments
(VBEs). We propose different levels of representation for the functional
structures and processes that VBEs and VOs involve, which are independent of
the specificities of the infrastructures (organisational and technical) that
support the functioning of VBEs. This allows us to reason about properties of
tasks performed within VBEs and services provided through VOs without
committing to the way in which they are implemented
Towards a Formal Model of Privacy-Sensitive Dynamic Coalitions
The concept of dynamic coalitions (also virtual organizations) describes the
temporary interconnection of autonomous agents, who share information or
resources in order to achieve a common goal. Through modern technologies these
coalitions may form across company, organization and system borders. Therefor
questions of access control and security are of vital significance for the
architectures supporting these coalitions.
In this paper, we present our first steps to reach a formal framework for
modeling and verifying the design of privacy-sensitive dynamic coalition
infrastructures and their processes. In order to do so we extend existing
dynamic coalition modeling approaches with an access-control-concept, which
manages access to information through policies. Furthermore we regard the
processes underlying these coalitions and present first works in formalizing
these processes. As a result of the present paper we illustrate the usefulness
of the Abstract State Machine (ASM) method for this task. We demonstrate a
formal treatment of privacy-sensitive dynamic coalitions by two example ASMs
which model certain access control situations. A logical consideration of these
ASMs can lead to a better understanding and a verification of the ASMs
according to the aspired specification.Comment: In Proceedings FAVO 2011, arXiv:1204.579
Service-oriented Approach Supporting Dynamic Manufacturing Networks Operations
[EN] In the current economic crisis, also the manufacturing sector is asked to evolve towards more dynamic organizational structures within which, composing manufacturing processes, almost in real time, will become a need. This work aims at introducing flexibility and dynamisms to current manufacturing processes by separating its tasks from its final performers. With the proposed approach, the performers replacement can be done almost seamlessly. Additionally, the approach shows how dynamic negotiation and contracting, either for a whole process or a single activity, can be smoother if the task specification is based on a standard service interface defined at the ecosystem level. At the end, a prototype implementation is briefly described.Franco Pereyra, RD.; Ortiz Bas, Á.; Gómez-Gasquet, P. (2013).

A structured approach to VO reconfigurations through Policies
One of the strength of Virtual Organisations is their ability to dynamically
and rapidly adapt in response to changing environmental conditions. Dynamic
adaptability has been studied in other system areas as well and system
management through policies has crystallized itself as a very prominent
solution in system and network administration. However, these areas are often
concerned with very low-level technical aspects. Previous work on the APPEL
policy language has been aimed at dynamically adapting system behaviour to
satisfy end-user demands and - as part of STPOWLA - APPEL was used to adapt
workflow instances at runtime. In this paper we explore how the ideas of APPEL
and STPOWLA can be extended from workflows to the wider scope of Virtual
Organisations. We will use a Travel Booking VO as example.Comment: In Proceedings FAVO 2011, arXiv:1204.579
A generic vobe framework to manage home healthcare collaboration
In this paper we propose a conceptual framework to manage Home HealthCare (HHC) provision and
stakeholder collaborations using the concepts of Virtual Breeding Environment (VBE) and Virtual
Organisation (VO). Providing healthcare at home is gaining popularity as more and more patients prefer to
receive care in the comfort of their homes. Providing care at home is complex and involves many
stakeholders; collaboration and resource sharing between these stakeholders is essential for a successful
home healthcare provision. In this paper we outline a framework to classify different parties involved in
Home Healthcare (HHC) collaboration based on their roles. The framework consists of two main
components which we call HHC-VBE and HHC-VO. The proposed framework is applied to a simple home
healthcare case study and it is later evaluated. The result shows that the framework is simple and flexible
and can be applied to other scenarios. This research contributes towards addressing the ongoing challenge
of HHC collaboration management
