Methodology for Designing Decision Support Systems for Visualising and Mitigating Supply Chain Cyber Risk from IoT Technologies

This paper proposes a methodology for designing decision support systems for visualising and mitigating the Internet of Things cyber risks. Digital technologies present new cyber risk in the supply chain which are often not visible to companies participating in the supply chains. This study investigates how the Internet of Things cyber risks can be visualised and mitigated in the process of designing business and supply chain strategies. The emerging DSS methodology present new findings on how digital technologies affect business and supply chain systems. Through epistemological analysis, the article derives with a decision support system for visualising supply chain cyber risk from Internet of Things digital technologies. Such methods do not exist at present and this represents the first attempt to devise a decision support system that would enable practitioners to develop a step by step process for visualising, assessing and mitigating the emerging cyber risk from IoT technologies on shared infrastructure in legacy supply chain systems

Construction safety and digital design: a review

As digital technologies become widely used in designing buildings and infrastructure, questions arise about their impacts on construction safety. This review explores relationships between construction safety and digital design practices with the aim of fostering and directing further research. It surveys state-of-the-art research on databases, virtual reality, geographic information systems, 4D CAD, building information modeling and sensing technologies, finding various digital tools for addressing safety issues in the construction phase, but few tools to support design for construction safety. It also considers a literature on safety critical, digital and design practices that raises a general concern about ‘mindlessness’ in the use of technologies, and has implications for the emerging research agenda around construction safety and digital design. Bringing these strands of literature together suggests new kinds of interventions, such as the development of tools and processes for using digital models to promote mindfulness through multi-party collaboration on safet

A hierarchical approach to multi-project planning under uncertainty

We survey several viewpoints on the management of the planning complexity of multi-project organisations under uncertainty. A positioning framework is proposed to distinguish between different types of project-driven organisations, which is meant to aid project management in the choice between the various existing planning approaches. We discuss the current state of the art of hierarchical planning approaches both for traditional manufacturing and for project environments. We introduce a generic hierarchical project planning and control framework that serves to position planning methods for multi-project planning under uncertainty. We discuss multiple techniques for dealing with the uncertainty inherent to the different hierarchical stages in a multi-project organisation. In the last part of this paper we discuss two cases from practice and we relate these practical cases to the positioning framework that is put forward in the paper

A Conceptual Framework for Mobile Learning

Several technology projects have been launched to explore the opportunities that mobile technologies bring about when tackling issues of democratic participation and social inclusion through mobile learning. Mobile devices are cheaper than for instance a PC, and their affordance, usability and accessibility are such that they can potentially complement or even replace traditional computer technology. The importance of communication and collaboration features of mobile technologies has been stressed in the framework of ICT-mediated learning. In this paper, a theoretical framework for mobile learning and e-inclusion is developed for people outside the conventional education system. The framework draws upon the fields of pedagogy (constructivist learning in particular), mobile learning objects and sociology.Mobile Learning, Digital Divide, Constructivist Pedagogy, Forms Of Capital

Decision Making in Near Zero Energy Building Refurbishment: A Technology Alternatives Ranking Tool

International audienceDecision making in the context of Near Zero Energy Building refurbishment is subjected to heterogeneous stakeholders, tools and objectives. This paper presents a methodology to facilitate stakeholders collaboration in the refurbishment processes and identifies decision support approaches to help on the main decision milestones. This methodology is supported by a prototype (user interface and algorithm) of a decision support system (DSS) that allows ranking different refurbishment technologies. The proposed DSS uses a multi criteria decision method that combines weighting and fuzzy dominances approach. The approach is illustrated with a real data set to rank insulation materials

Cybersecurity Risk-Responsibility Taxonomy: The Role of Cybersecurity Social Responsibility in Small Enterprises on Risk of Data Breach

With much effort being placed on the physical, procedural, and technological solutions for Information Systems (IS) cybersecurity, research studies tend to focus their efforts on large organizations while overlooking very smaller organizations (below 50 employees). This study addressed the failure to prevent data breaches in Very Small Enterprises (VSEs). VSEs contribute significantly to the economy, however, are more prone to cyber-attacks due to the limited risk mitigations on their systems and low cybersecurity skills of their employees. VSEs utilize Point-of-Sale (POS) systems that are exposed to cyberspace, however, they are often not equipped to prevent complex cybersecurity issues that can result in them being at risk to a data breach. In addition, the absence of federal laws that force VSEs to adhere to standards such as the Payment Card Industry Data Security Standard (PCI-DSS) leaves it up to the discretion of the VSEs to invest in cybersecurity countermeasures aimed at preventing a data breach. Therefore, this study investigated the role that cybersecurity social responsibility plays in motivating the owners of these companies to engage in cybersecurity measures geared at preventing data breaches.This study developed and validated using Subject Matter Experts (SMEs) a cybersecurity risk-responsibility taxonomy using the constructs of VSEs’ owners’ perceived cybersecurity social responsibility (CySR) and risk of data breach (RDB) in order to better understand their level of exposure to a data breach. Exploratory Factor Analysis (EFA) using Principal Component Analysis (PCA) was conducted to extract the significant factors for CySR and RDB. The study also addressed whether there were significant differences in VSEs owners’ perceived RDB and perceived CySR based on three demographics: (1) type of industry, (2) implementation of chip technology, (3) compliance with PCI-DSS. This study was conducted in three phases. Phase 1 utilized a panel of 13 information security SMEs and used the Delphi technique to review characteristics for RDB and CySR that were derived from literature. The results of the expert review were subjected to further validation by means of a pilot study using a small sample of the study population (Phase 2). The pilot study population included 20 organizations with number of employees ranging from less than five to 50 total employees across seven different industries. Phase 3 of the study included the main data collection using the modified survey instrument from the pilot study. 105 VSEs anonymously participated in the main data collection phase of the study. The collected data was subjected data EFA which identified three factors comprised of 15 items for RDB and two factors comprised of 13 items for CySR. In addition, descriptive statistics was obtained and evaluated to determine if significant differences exist in VSEs owners’ perceived RDB based on type of industry, implementation of Europay, Mastercard and Visa (EMV) chip technology and, compliance with PCI-DSS. One-way Analysis of variance (ANOVA) was used to evaluate whether significant differences existed based on the VSEs demographics. The results of the study indicated that there was a statistically significant difference in both RDB and CySR for industry, use of EMV Chip and, PCI-DSS compliance. This study demonstrates that there is a relationship between CySR and cybersecurity and that the CySR instrument could be used to assess cybersecurity practices in small businesses. In addition, this study may assist organizations in understanding and mitigating cybersecurity data breaches
