The interfaces of each component inside the framework as well as to external communication end points are the main focus of this document.<br> Each component is described in a separate subsection of Section 3. These subsections are divided into five topics to provide a complete picture on how these components are designed and how they interact. In each component, the programming language as well as the libraries and frameworks used are described based on experience and problem domain. Also, the corresponding deployment strategies are covered in the component sections. The last section gives a short summary of the development since D2.6 - FLEXCoop Framework Architecture including functional, technical and communication specifications.<br> As this is a follow up deliverable to D2.6 this document focuses on the changes since D2.6 and should be read with D2.6 at hand.

Therefore, SMEs should enhance their current business model in a way that would give them a competitive advantage. This paper presents work from the European-funded research project ToyLabs that aims to build on this identified need to establish a new, collaborative value chain for product development in the toy industry, with business interoperability playing a key role in this quest. The methodology engages toy manufacturers, FabLabs, toy safety experts and end customers in the product design workflow to create new, safe customer-centred and market-targeted toys that are ready to be certified and put into production. For achieving the goals of this approach, the methodology behind the ToyLabs platform focuses on the incorporation of cross-sectorial business process interoperability capabilities that aim to create a common vocabulary, understanding and a c...

In this context, this paper introduces an innovative way of performing Verification and Validation activities, which brings together both the technical and the business viewpoints and can be applied throughout the whole lifecycle of the software product. It describes the necessary steps, the techniques to be applied for each step, the roles to be involved, and suggestions for crowd assessment. It is developed taking into account its application in manufacturing settings, yet it is reusable to any project that has software development tasks and follows either the traditional waterfall method or invests on agile software building patterns.

It’s an issue of doing things in new ways that requires fundamental change in the provision of public services in the future and a complete new approach for Governments to work and interact with their citizens. Currently, Societies witness more than ever that Web 2.0 and social media in particular, constitute the emerging, if not already established, mass collaboration and cooperation platform between citizens and administrations, as the latter have started to realise the benefits of such applications. The COCKPIT project builds on these developments and based on a highly synergetic approach aims to define a new Governance model for the next generation public service delivery, by combining various research areas.

The purpose of this paper is to outline a general multicriteria decision support method in order to identify the services that, if transformed to electronic ones, would act as ambassadors of the new era. Various technological, social, political and economic criteria have been taken under consideration. The proposed model is based on the Analytic Network Process (ANP), which takes into account both tangible and intangible criteria with interdependencies and feedback among them. A real case scenario concerning a Public Services selection process in Greece has been used to validate the presented model.

The decision of joining a DMN however is quite important for any enterprise, since beside significant benefits it brings about changes in the way it operates, bearing thus also considerable risks. This paper attempts to cultivate an understanding around the risks of DMN participation, utilizing the causal characteristics of Cognitive Maps (CMs) for identifying the causes of unsatisfactory or unaccepted DMN operation outcomes. It further elaborates on how DMN risks are inherently dealt with through the IMAGINE framework that guarantees business alignment and interoperability.

The establishment of Dynamic Manufacturing Networks (DMNs) brings together various innovations, such as just-in-time delivery, flexible manufacturing, organizational streamlining, and total quality, and emerges therefore as an advanced reaction of collaborating enterprises to the constantly changing business environment and its characteristics. This paper aims to expose the benefits and risks involved in such networks, and create thereby the foundation for elaborating further on the key factors that could be utilized for attracting organizations and enterprises into embracing the vision of DMNs, supporting thus not only industrial organizations and practitioners interested in implementing such solutions, but also scholars and researchers who study these new forms of business.

Distributed and flexible manufacturing configurations have been around the latest years, however the lack of an agile and responsive management methodology of such structures has hindered them from reaching their full potential. Today, the novel concept of Dynamic Manufacturing Networks stands out as a cutting-edge solution in this quest, carrying a wide set of assets that aim to drive manufacturing organisations into the new global economy. This concept is incarnated through the IMAGINE DMN end-to-end Management Methodology presented in this paper, along with the benefits and risks that the former promises to respectively enhance and mitigate.

The study at hand aims to review current approaches for controlling and monitoring plant operation or traditional supply chains, and to examine thereby their maturity and adequacy for the management and monitoring of dynamic manufacturing networks, leading to useful conclusions with regard to the requirements and challenges encountered in this particular phase of the DMN lifecycle.

The decision making process is highly complex, especially for public organisations, as it encompasses various, often conflicting criteria. Moreover they have to consider a much larger picture than private organisations and many scholars argue that public investment decisions fall into the category of constrained optimisation problems. The present study develops and proposes an approach for the prioritization of public projects, based on the Analytic Network Process (ANP), which is further validated through a real case example concerning the project selection process of a Greek municipality. The results indicate that social and political criteria dominate the decision making process, while the ANP documents the results in such way that they can be communicated to various stakeholders, ensuring public trust and establishing a system of transparency in public administration.
