Dilemmas in designing e-learning experiences for professionals
- 2021
-
Ingår i: Proceedings of the European Conference on e-Learning, ECEL. ; , s. 10-17

Konferensbidrag (refereegranskat)abstract
- The aims of this research are to enhance industry-university collaboration and to design learning experiences connecting the research front to practitioners. We present an empirical study with a qualitative approach involving teachers who gathered data from newly developed advanced level courses in artificial intelligence, energy, environmental, and systems engineering. The study is part of FutureE, an academic development project over 3 years involving 12 courses. The project, as well as this study, is part of a cross-disciplinary collaboration effort. Empirical data comes from course evaluations, course analysis, teacher workshops, and semi-structured interviews with selected students, who are also professionals. This paper will discuss course design and course implementation by presenting dilemmas and paradoxes. Flexibility is key for the completion of studies while working. Academia needs to develop new ways to offer flexible education for students from a professional context, but still fulfil high quality standards and regulations as an academic institution. Student-to-student interactions are often suggested as necessary for qualified learning, and students support this idea but will often not commit to it during courses. Other dilemmas are micro-sized learning versus vast knowledge, flexibility versus deadlines as motivating factors, and feedback hunger versus hesitation to share work. Furthermore, we present the challenges of providing equivalent online experience to practical in-person labs. On a structural level, dilemmas appear in the communication between university management and teachers. These dilemmas are often the result of a culture designed for traditional campus education. We suggest a user-oriented approach to solve these dilemmas, which involves changes in teacher roles, culture, and processes. The findings will be relevant for teachers designing and running courses aiming to attract professionals. They will also be relevant for university management, building a strategy for lifelong e-learning based on co-creation with industry.

An Agent-Based Ontology to Support Modeling of Socio-Technical Systems-of-Systems
- 2024
-
Ingår i: INCOSE International Symposium. - : INCOSE. ; 34:1, s. 1705-1718
-
Tidskriftsartikel (refereegranskat)abstract
- Systems-of-systems are characterized by the independence of their constituent elements. Such an element is usually socio-technical, comprising technology, humans, or organizations. To capture its independence, it needs to be viewed as an intelligent agent that relies on an internal model of the world for its decision-making. Hence, a system-of-systems model will include multiple agents that inside themselves contain different models of the same system-of-systems. Describing these overlapping subjective models and their usage by the agents is essential to properly understand the resulting behavior of the overall system-of-systems. Current modeling practices are not well suited for dealing with this, and the paper therefore outlines an ontology that makes the agents and their internal models more explicit. The paper also discusses the implications such models have on systems engineering practices and how they address known system-of-systems engineering pain points.

Higher-Level Capabilities of System-of-Systems Constituents : A Case of Industrial Ecosystems
- 2023
-
Ingår i: 2023 18th Annual System of Systems Engineering Conference, SoSe 2023. - : Institute of Electrical and Electronics Engineers Inc.. - 9798350327236
-
Konferensbidrag (refereegranskat)abstract
- In a system-of-systems, independent constituent systems collaborate to achieve broader capabilities they cannot provide on their own. This paper investigates the nature of the constituent system capabilities beyond basic operational actions, to achieve a deeper understanding of what is required to participate in a system-of-systems. Through a case study of industrial ecosystems, the need is shown for planning how to use basic operational capabilities, for dynamic capabilities to achieve long-term evolution, and for resilience capabilities to deal with perturbations. This also affects the governance of the system. The findings are used to extend an existing conceptual model of constituent systems and to characterize collaboration in a system-of-systems that implements a value network.

Mediators in Systems-of-Systems and Ecosystems : A Systematic Literature Review and Conceptualization
- 2024
-
Ingår i: Proceedings - 2024 IEEE/ACM 12th International Workshop on Software Engineering for Systems-of-Systems and Software Ecosystems, SESoS 2024. - : Association for Computing Machinery, Inc. - 9798400705571 ; , s. 21-28
-
Konferensbidrag (refereegranskat)abstract
- In most systems-of-systems (SoS) and ecosystems, peer-to-peer relations are insufficient to provide the desired emergent behavior, but the support of mediators is necessary. Mediators are elements that facilitate the collaboration between the constituents of the SoS or ecosystem, without having a role outside it. The topic has previously been studied in the SoS field, mainly from a software engineering perspective, and separately also in research on software, business, and innovation ecosystems. This paper presents a systematic literature review on mediators across scholarly work in SoS as well as ecosystems. It identifies mediator functionality and implementation concerns, and discusses alternative terminology. Based on findings from the literature, a suggestion for an improved conceptualization is presented, which also includes the information, processing and interactions involved in the mediation.

Needs and Architectural Strategies Related to Geospatial Information in Systems-of-Systems
- 2020
-
Ingår i: SOSE 2020 - IEEE 15th International Conference of System of Systems Engineering, Proceedings. - : Institute of Electrical and Electronics Engineers (IEEE). - 9781728180502 ; , s. 111-116
-
Konferensbidrag (refereegranskat)abstract
- This paper puts forward the hypothesis that all systems-of-systems (SoS) need to deal with geospatial information. It discusses some fundamental aspects of such geodata, including entities, coordinate systems, features, and representation. It then presents how geodata can be used for various purposes in SoS and suggests architectural strategies for handling geodata in this context, including the use of linked data to represent both geodata and other information; triple stores for databases; and cloud servers for executing geodata related constituent system functionality.

On the Concepts of Capability and Constituent System Independence in Systems-of-Systems
- 2022
-
Ingår i: 2022 17th Annual System of Systems Engineering Conference, SOSE 2022. - : Institute of Electrical and Electronics Engineers Inc.. - 9781665496230 ; , s. 247-252
-
Konferensbidrag (refereegranskat)abstract
- Systems-of-systems are designed to provide a capability that their constituent systems cannot achieve individually. A key property is that the constituent systems have some degree of operational and managerial independence. The concepts of capability and independence are thus central to the field of systems-of-systems. Yet the contemporary literature and standards only give vague definitions of these terms. This vagueness is a barrier to progress in the field, and this paper aims at contributing with a more detailed conceptualization. It describes a system capability as a state-transforming process that uses certain resources. Independence means that the system has a choice about when and how its capabilities should be activated. This requires that the system is an intelligent agent with a notion of utility, a perception of the world around it, and a decision-making capability. When given a mission, the system can complete that mission by activating appropriate combinations of capabilities. A system-of-systems can decompose its mission into parts that correspond to the capabilities of various constituent systems.

Systems-of-Systems Design Patterns : A Systematic Literature Review and Synthesis
- 2022
-
Ingår i: 2022 17th Annual System of Systems Engineering Conference, SOSE 2022. - : Institute of Electrical and Electronics Engineers Inc.. - 9781665496230 ; , s. 171-176
-
Konferensbidrag (refereegranskat)abstract
- Design patterns are an established approach for reusing knowledge about good solutions to recurring problems. Patterns can be seen as a way of describing the best practices, and have been used in many different fields, ranging from building architecture and city planning to software development. There are also scattered results relating to patterns for systems-of-systems. The purpose of this paper is to summarize and review the literature on patterns for systems-of-systems and make a synthesis of a recommended approach for the field. Specifically, the novel contributions of the paper are to propose a consolidated structure for describing individual patterns and suggest the dimensions along which a pattern catalog can be organized. The paper also summarizes the concrete patterns suggested in the existing literature and classifies them according to the recommended structure.

Truck Platooning Business Case Analysis
- 2020
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In this report we describe results from the work on business case analysis of the Sweden for Platooning (S4P) project. Platooning has the potential to contribute to the on-going transformation of the transport sector by reducing environmental impact, saving fuel, as well as (to a lesser extent) by improving traffic flow and safety and in the long run reducing driver hours. In order to fulfil these promises, it must be shown that there are viable business cases for all involved actors. This report describes the analysis of truck platooning business cases performed in the S4P project.Some of the main findings are that there is a significant potential for reducing fuel consumption and hence CO2 exhaust through platooning; that waiting on the order of minutes for a platooning opportunity is reasonable but that taking another route is probably not; that it is necessary to have mediating services that help platoons to form and share the costs and benefits associated with platooning; and that there are different possible ways of implementing a system for sharing the benefits.
