- The complexity of systems continues to increase rapidly, especially due to the multi-level integration of subsystems from different domains into cyber-physical systems. This results in special challenges for the efficient verification and validation (V&V) of these systems with regard to their requirements and properties. In order to tackle the new challenges and improve the quality assurance processes, the V&V workflows have to be documented and analyzed. In this paper, a novel approach for the workflow modelling of V&V activities is presented. The generic approach is tailorable to different industrial domains and their specific constraints, V&V methods, and toolchains. The outcomes comprise a dedicated modelling notation (VVML) and tool-support using the modelling framework Enterprise Architect for the efficient documentation and implementation of workflows in the use cases. The solution enables the design of re-usable workflow assets such as V&V activities and artifacts that are exchanged between workflows. This work is part of the large scale European research project VALU3S that deals with the improvement and evaluation of V&V processes in different technical domains, focusing on safety, cybersecurity, and privacy properties.

A Proposal for the Classification of Methods for Verification and Validation of Safety, Cybersecurity, and Privacy of Automated Systems

Konferensbidrag (refereegranskat)abstract
- As our dependence on automated systems grows, so does the need for guaranteeing their safety, cybersecurity, and privacy (SCP). Dedicated methods for verification and validation (V&V) must be used to this end and it is necessary that the methods and their characteristics can be clearly differentiated. This can be achieved via method classifications. However, we have experienced that existing classifications are not suitable to categorise V&V methods for SCP of automated systems. They do not pay enough attention to the distinguishing characteristics of this system type and of these quality concerns. As a solution, we present a new classification developed in the scope of a large-scale industry-academia project. The classification considers both the method type, e.g., testing, and the concern addressed, e.g., safety. Over 70 people have successfully used the classification on 53 methods. We argue that the classification is a more suitable means to categorise V&V methods for SCP of automated systems and that it can help other researchers and practitioners.

Policies supporting reuse, collective use and prolonged life-time of textiles
- 2019
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In 2016 138 000 tonnes of new clothes and household textiles were put on the Swedishmarket (Statistics Sweden, 2017). The production of textile products causes significantenvironmental impacts. Business models engaged in reuse, collective use and prolongedlife-time of textiles therefore have a potential to contribute to reduced total textileconsumption and, as a consequence, reduced environmental impacts from textileproduction.Preceding work in Mistra Future Fashion (Watson et al, 2017) identified ten differentsupporting policy instruments for business models that extend active lifetimes ofgarments. The objective of this report is to select three of the previously identified policyinstruments and estimate the economic, environmental, social effects of these. The threepolicy instruments selected for further assessment were:- A wage subsidy earmarked for businesses that extend the active lifetime of textiles- A knowledge hub assisting businesses start up or transition to more circular models- Start-up/transition fund for business models/initiatives that extend the activelifetime of textiles.
