Democratic decision making processes play a crucial role in any society, but also in organizations, especially those containing large interest groups and distributed stakeholders. Likewise, digitalization is at the forefront among companies in recent years. This study captures the development of a digital voting system with convincing performance, as a response to the requirements for such a solution that evolved from the case company on hand. We deploy the service-oriented architecture described in the Arrowhead Framework for a wearable device, equipped with a barometric pressure sensor (to capture the height) and the ESP8266 microcontroller to process data and calculate voting results. We validate the proposed approach by comparing its capabilities in terms of response time, user-friendliness and distributivity against a conventional version to demonstrate performance advantages. We find that by integrating the Arrowhead Framework, a distribution decision making solution is feasible, which serves as proof of concept for the case company we are collaborating with. In essence, it (i) reveals implications for managers that service-oriented architecture is a promising cornerstone for distributed connectivity, and (ii) provides initial guidance for developers, how such distributed democratic decision making may be set up in practice.

Engineering and programming approaches for collective adaptive systems often leverage ensemble-like abstractions to characterise a subset of devices as a domain for a given task or computation. In this paper, we address the problem of programming the dynamic evolution of distributed computational aggregates, through neighbour-based coordination. This is a problem of interest, since several situated activities (especially in large-scale settings) require decentralised collaboration, and need to be sustained by limited subsets of devices. These subsets may vary dynamically due to delegation, completion of local contributions, exhaustion of resources, failure, or change in the device set induced by the openness of system boundaries. In order to study and develop how distributed aggregates progressively take form by local coordination, we build on the field-based framework of aggregate processes, and extend it with techniques to support more expressive evolution dynamics. We propose novel algorithms for more effective propagation and closure of the boundaries of dynamic aggregates, based on statistics on the information speed and a notion of progressive closure through wave-like propagation. We verify the proposed techniques by simulation of a paradigmatic case study of multi-hop message delivery in mobile settings, and show increased performance and success rate with respect to previous work.

distributed real-time simulation (D-RTS) has been proposed as an alternative solution for the simulation of large-scale power systems. D-RTS interconnects heterogeneous and remote real-time resources virtually in order to combine and extend their simulation capabilities. A reliable D-RTS framework is necessary to virtually interconnect subsystems and manage simulation data in real time. D-RTS has mainly been implemented to combine standalone models, which only shows the feasibility and increased computing capability. However, the behavior of D-RTS has not been appropriately assessed nor investigated for decoupling models. On this basis, this paper investigates power system model decoupling and verifies its implementation for the purposes of D-RTS. The ieee Australian Benchmark model is used as a case study. The implementation, operation, and performance of the distributed model are benchmarked against its monolithic counterpart. Results validate the simulation of the distributed model under both steady-state and transient operation, demonstrating that power system models can be decoupled in order to perform real-time simulations in a distributed manner under certain conditions.
