During these interviews, IEEE 1471-2000 (Hilliard 2000) standard is used, which is a recommended practice for Architectural Description of Software-Intensive Systems. This standard requires that the system should be introduced systematically by means of a system definition, including environment description, mission and stakeholders’ identification, and architecture descriptions. These architecture descriptions include a series of architectural views and model definitions, each having viewpoints and concerns. In order to demonstrate the proposed system, a presentation based on IEEE 1471-2000 was made prior to each interview. This presentation included conceptual graphs, top-level architectural views, class diagrams, detailed views for critical parts, data structures, definitions, scenarios, user interface screenshots, demonstrative information for the available display type libraries and their integration to the proposed system, and code parts to describe various interoperability or algorithmic details. While other standard information is presented in the slides, the rationality of each presented item is explained verbally to the reviewer. Adequateness of the development infrastructure is a significant issue that is questioned for cyber-physical systems because wrong development infrastructure will result in unscalable solutions with low performances or bad security. Numerical scores given related to each requirement item are shown in Table 9.2. Other information is in Table 9.4.

The system architecture was designed following the guidelines from IEEE Standard 1471–2000 (IEEE 2000), with some necessary adaptations to design an evolutionary, interoperable platform. The architecture is part of the rehabilitation system, which aims to provide surrogate coaching with real-time performance evaluations with interoperable software and hardware components. The architectural description identifies the involved stakeholders (i.e. clinical experts, patients, data analysts), establishes current and expected user needs and provides the technological capabilities (i.e. IoT and user interaction devices) and functionality (i.e. cloud, edge computing), in order to meet the requirements and rationale of the platform. The main motivation for adopting the iterative architecture design of IEEE 1471 is that the architecture, the delivered systems and the stakeholders coevolve, and as a result, architectural descriptions and models have to be developed emphasising on flexibility and adaptability. Thus, all technologies used are platform agnostic and each system module is required to implement a predefined contract for data exchange, using a common communication protocol to ensure seamless connectivity between IoT devices and cloud infrastructures.

The research reported upon in this paper is based on a design-oriented methodology. Design-oriented research focuses on building purposeful artefacts that address heretofore unsolved problems and are evaluated with respect to the utility provided in solving those problems (March and Smith 1995; Hevner et al. 2004). The design artefact developed in the present paper is a reference architecture for IoT-based logistic information systems in agri-food supply chains. Architecture can be defined as the fundamental organisation of a system embodied in its components, their relationships to each other and to the environment, and the principles guiding its design and evolution (IEEE 1471:2000). Reference architectures are predefined models of recommended practices that are used as a ‘frame of reference,’ and, as such, they improve quality, costs and lead-times of information modelling processes (Verdouw, Beulens, Trienekens, and Verwaart 2010). Reference architectures can represent different architectural views, depending on the purpose of usage. The present research aims to use Future Internet technologies for logistic applications in agri-food supply chains. Consequently, the architecture should especially represent the interactions between functionalities and technological implementation. For this reason, we have chosen a combination of a process view, service view and technical view. These views are modelled in the Archimate methodology (The Open Group 2012; Lankhorst 2013) using Archi, an open source Archimate modelling tool (Archi 2012).
