This article describes the process of developing a framework and an instrument for measuring and ascertaining the openness of a system applicable to system architectures and their implementations. Our process includes an in-depth review of pertinent literature in the areas of Open Systems and Open Architecture, followed by a selection of the appropriate methodology to use. We chose the Goal-Question-Metric (GQM) methodology to allow us to select relevant goals, factors and metric that can be used to measure a system's level of openness. The article details these goals, factors and metrics. We carried out studies of these factors with fourteen experts in open systems engineering: an initial study with seven of these experts helping us refine the selected goals, factors and metrics, with a second confirmatory study performed in conjunction with the remaining seven experts. The goals, questions and metrics are detailed in the appendices.

The Way

This paper describes the way in which Systems Engineering has been used to map out and address the technical, operational and regulatory considerations necessary for autonomous platform management of Unmanned Surface Vehicles. Building on an approach originally developed for Unmanned Aerial Vehicles, Model-Based Systems Engineering has been used to derive the context and requirements for this high-level ship control system to ensure that it is properly structured, adaptable and re-useable. Mapping out use cases of the platform systems of a large, complex unmanned ship has allowed the functional requirements to be derived rigorously and therefore informs the selection of the most efficient architecture and interfaces ahead of software creation. This practical application of Systems Engineering has paved the way to the creation of robust, open-architecture control of platform systems which enables vessel autonomy in the Naval domain.

Model Based Systems Engineering

Today, vehicle development is already in a process of substantial transformation. Mobility trends can be derived from global megatrends and have a significant influence on the requirements of the developed vehicles. The sociological, technological, economic, ecological, and political developments can be determined by using the scenario technique. The results are recorded in the form of differently shaped scenarios; however, they are mainly document-based. In order to ensure a holistic approach in the sense of model-based systems engineering and to be able to trace the interrelationships of the fast-changing trends and requirements, it is necessary to implement future scenarios in the system model. For this purpose, a method is proposed that enables the consideration of future scenarios in model-based vehicle development. The procedure of the method is presented, and the location of the future scenarios within the system architectures is named. The method is applied and the resulting system views are derived based on the application example of an autonomous people mover. With the help of the described method, it is possible to show the effects of a change of scenario (e.g., best-case and worst-case) and the connections with the highest level of requirements: stakeholder needs.

AbstractAs digitization progresses, the integration of information and communication technologies in technical systems is constantly increasing. Fascinating value potentials are emerging (e.g. autonomous driving), but also challenges in the system development. The constantly increasing product complexity and degree of networking require a systemic development, which is fulfilled by established approaches of Model-Based Systems Engineering (MBSE). To ensure the reliability of tomorrow's systems, an integrative and early consideration of security and safety is additionally required. In order to show the possibility and consequences of failures and attacks, the paper develops a modeling language that links established and partly isolated security and safety approaches within a consistent metamodel. The developer is enabled to synthesize system architectures transparently on an interdisciplinary level and to analyze attack and failure propagation integratively. The approach uncovers synergetic and especially contrasting goals and effects of architectural designs in terms of safety and security in order to make adequate architectural decisions based on trade-off analyses.

Connected and automated vehicle (CAV) technologies could transform the transportation system over the coming decades, but face vehicle and systems engineering challenges, as well as technological, economic, demographic, and regulatory issues. The authors have developed a system dynamics model for generating, analyzing, and screening self-consistent CAV adoption scenarios. Results can support selection of scenarios for subsequent computationally intensive study using higher-resolution models. The potential for and barriers to large-scale adoption of CAVs have been analyzed using preliminary quantitative data and qualitative understandings of system relationships among stakeholders across the breadth of these issues. Although they are based on preliminary data, the results map possibilities for achieving different levels of CAV adoption and system-wide fuel use and demonstrate the interplay of behavioral parameters such as how consumers value their time versus financial parameters such as operating cost. By identifying the range of possibilities, estimating the associated energy and transportation service outcomes, and facilitating screening of scenarios for more detailed analysis, this work could inform transportation planners, researchers, and regulators.

Nanoscale experiments with diamond tip that include processing, visualization and tunneling spectroscopy of the surface are presented. Single crystal diamond synthesized by the temperature gradient method under high pressure–high temperature (HPHT) conditions is proposed as a multifunctional tip for scanning tunneling microscopy (STM). Sequence of the procedures covering growing crystals with predetermined physical properties, selection of the synthesized crystals with the desired habit and their precise shaping have been developed. The original STM’s peculiarity is the electromagnetic probe-to-surface load measuring system. The results of fabrication and characterization of nanostructures for nanoelectronics, data storages and biology are demonstrated and discussed.

The trade-off between flexibility and specialisation implies delicate tasks for transport system designers and marketing managers. The outcome of their efforts ranges from highly specialised solutions for a restricted number of users and types of cargoes to very open systems for common use adapted to accommodate a wide variety of transport demands. The purpose of this article is to adapt theories on openness and trade-offs, characterise a selection of flexible and specialised European short sea shipping concepts and analyse how substantial changes in the future character of the competition with road and rail can affect the development of ro-ro shipping in the South Baltic Sea. A matrix with commercial openness and technological openness on the axes is used for categorising sub-segments in the empirical context of the South Baltic Sea. Foreseeable changes in key cost and competition parameters until 2020 are taken into account in discussing potential scenarios. A plausible outcome for the ferry/ro-ro shipping segment is that a branch with slow services for unaccompanied freight will be diverted from the current homogenous market offerings. During the study, the Swedish Orient Line launched a service with these characteristics, which is analysed in a case study.

PurposeThe purpose of this paper is to find evidence of the benefits and constraints of collaborative consumption experiences by investigating the perceptions of hosts and visitors that attended professional regular season basketball and baseball games in the USA.Design/methodology/approachData were collected through four focus groups with 37 total participants and were analyzed through qualitative content analysis.FindingsThe results show that participants in a collaborative consumption experience perceive four types of value: social interaction and belonging, new fandom, travel bucket list experiences and local and sport knowledge. In addition, the results provide evidence of five consumption constraints related to collaborative consumption: expenses, average experiences, seat location, interpersonal disconnects and personal risk.Research limitations/implicationsThe selection of only two sites for the study limited the data triangulation that was possible. This study should be replicated across a wider range of teams and countries to confirm the main findings of the study.Practical implicationsPractitioners can use this initial study to better understand the benefits hosts and visitors perceive in the experience, and therefore the kind of experience design that would encourage increased purchases and loyalty.Originality/valueThis paper provides qualitative insights into the benefits and detriments of a collaborative consumption sport experience, based on participants' involvement in an innovative peer-to-peer platform.
