International audience; The ongoing digital transformation raises the need to address the evolution of legacy systems in response to integration requirements. One challenge is integrating sensors and actuators (and their controllers), modeled as IoT elements, and linking them to data analytics, management, and operations decision support functions or processes. Since legacy technology systems follow proprietary architectures, their integration into open service-oriented architectures (SOA) requires a strategy that maintains a high degree of reliability. This paper presents the strategy adopted to integrate legacy software in an open SOAto managean agri-food silos infrastructure. This approach follows the Informatics System of Systems (ISoS) idea and is based on the ISoS framework. A reference implementation concept is used to validate the (re)construction of legacy systems and make them ready for collaboration with agro-industry business partners considering their Enterprise Resource Planning. more...

International audience; Managing heterogeneous software and hardware artifacts frommultiple suppliers is a complex and challenging process. The integration of sensors, actuators, and their controllers, modeled as IoT elements, also presents significant challenges. Typically, a vendor supplies one or more parts, each one with its proprietary interface, which may raise vendor lock-in and supplier dependencies that can compromise the replacement of some of the artifacts by equivalent ones from competing vendors. The research presented in this paper addresses such challenges in the context of the SITL-IoT project aiming at transforming an industrial agri-food environment towards an open, integrated system-of-systems. We present and discuss a reference implementation of a collaborative platformto simplify themanagement of different artifacts, supplied by alternative suppliers, modeled as services. More specifically, the concepts of ISystem (Informatic System), CES (Cooperation Enabled Service), and Serviceare used to manage the different elements that compose an agri-food environment transparently and uniformly. We argue that the adopted model simplifies the collaboration among technology suppliers along the life cycle maintenance and evolution of their enabled products. more...

Part 2: Advanced Cyber Physical Systems; International audience; Legacy industrial infrastructures are facing complex challenges to evolve to integrated solutions through the adoption of novel computing and business paradigms. The fast-growing collaborative businesses introduce the additional complexity of managing cooperative interactions among systems of business partners. The SITL-IoT research project aims to develop an open integrated and collaborative systems landscape for the silos agri-food industry. This case considers a silos’ operator managing a maritime silos terminal in collaboration with the seaport administration, where trucks transfer bulk products to silos or bulk storages and distribute them to factories. The existing legacy management and supervision solutions are neither integrated nor properly prepared to cope with collaborative processes. Furthermore, the interactions with business partners are complex and follow dedicated integration solutions that pose difficult challenges in terms of management and evolution, since they do not follow open collaborative models or technology implementations. This paper discusses the problem domain and the approach to co-design and implement a technology-agnostic open integration infrastructure to support such collaborative network. The proposed approach considers a multi-supplier strategy for the adaptive integration of things on Internet of Things (IoT), considering the collaborative networks dimension. more...
