The Planning of Hyperloop-Based CargoTubes Routes for Sustainable Logistic Solutions
No full textCargoTube is an innovative approach for decarbonized, efficient, effective, and safe transport. A CargoTube is an Hyperloop-based transport system designed to transport goods. This paper demonstrates how such systems are planned by a traditional phased approach as used for the planning of road construction. The planning tasks are supported by tools such as spreadsheets, discrete event simulation and lifecycle performance assessment allowing the anticipation of performance from different perspectives including economic and environmental dimensions. An example connecting a Logistics Service Park (LSP) with an automotive production site is used to demonstrate the approach and to show the identified benefits of such a system in comparison with traditional transport approaches

Guest Editorial Machine Learning for Resilient Industrial Cyber-Physical Systems
No full textWith the rapid development of information technologies, the computing, networking, and physical elements in industrial environments are becoming tightly amalgamated with each other, resulting in the formation of the so-called Industrial Cyber-Physical Systems (ICPS). These systems forge the core of current real-world networked industrial infrastructures, having a cyber-representation of physical assets through digitalization of data across the enterprise, along the value stream and process engineering life cycle, along the digital thread, and along the supply chain. Typical applications of ICPS include smart grids, digital factory, cognitive and collaborative robots, freight transportation, process control, plant-wide systems, medical monitoring, etc. ICPS often operate in an unpredictable and challenging environment, where various disturbances, such as unplanned natural events, human faults or malicious behaviors, software and hardware failures, etc., may occur during the automation process at runtime. Moreover, ICPS can exhibit strong reconfigurability and evolve structurally for many purposes. During this evolution, new and unforeseen possibilities in the service-oriented business process may appear among various ICPS components. In particular, new “emergent” behaviors may arise that need to be monitored, understood, managed and controlled. When there are significant uncertainties, such emergent behaviors could make the evolved ICPS unstable and unable to meet the quality/performance targets, even resulting in hazards. Well-designed machine-learning techniques have the potential to effectively address the uncertainties and disturbances in the automation of ICPS. They can also facilitate the automated discovery of valuable underlying rules and patterns to improve the performance of ICPS in all phases of their life cycles

Which Challenges Do Exist With Agile Culture in Practice?
No full textContext: In agile transformations there are many challenges. One very important but less considered and treated in research are cultural challenges associated with an agile mindset. Although research shows that cultural clashes and general organizational resistance to change are part of the most significant agile adoption barriers. Objective: We identify challenges that arise from the interplay between agile culture and organizational culture. In doing so, we tackle this field and come up with important contributions for further research regarding a problem that practitioners face today. Method: This is done with a mixed-method research approach. First, we gathered qualitative data among our network of agile practitioners and derived in sum 15 challenges with agile culture. Then, we conducted quantitative data by means of a questionnaire study with 92 participants. Results: We identified 7 key challenges out of the 15 challenges with agile culture. These key challenges refer to the technical agility (doing agile) and the cultural agility (being agile). The results are presented in a conceptual model. Conclusion: Based on our results, we started deriving future work aspects to do more detailed research on the topic of cultural challenges while transitioning or using agile methods in software development and beyond
On the Importance of UX Quality Aspects for Different Product Categories
No full textUser experience (UX) is a holistic concept. We conceptualize UX as a set of semantically distinct quality aspects. These quality aspects relate subjectively perceived properties of the user interaction with a product to the psychological needs of users. Not all possible UX quality aspects are equally important for all products. The main use case of a product can determine the relative importance of UX aspects for the overall impression of the UX. In this paper, the authors present several studies that investigate this dependency between the product
category and the importance of several well-known UX aspects. A method to measure the importance of such UX aspects is presented. In addition, the authors show that the observed importance ratings are stable, i.e., reproducible, and hardly influenced by demographic factors or cultural background. Thus, the ratings reported in our studies can be reused by UX professionals to find out which aspects of UX they should concentrate on in product design and evaluation

The Task-Based Approach to Teaching Critical Thinking for Computer Science Students
No full textCritical thinking (CT) is one of the most important 21st-century skills that employers believe will grow in prominence. However, many higher education (HE) graduates often lack it. This is also true for graduates in computer science (CS) and related disciplines, who need CT to drive social and organizational digitalization. There are a number of strategies for teaching CT. However, there is no evidence regarding how to effectively teach CT in CS. To address this gap, this study proposes an educational approach that aims to promote CT to the students of CS and related disciplines. An educational experiment using this approach was conducted in two modules with similar content. The written reflections of 11 students on their development in CT and the quantitative data of students’ self-assessments of their CT skills and dispositions before (N = 20) and after (N = 11) the experiment were analyzed. Priority was given to the qualitative data. The results of this study support the hypothesis that the proposed approach has a positive impact on the development of students’ perceived CT skills. They also show that this approach stimulates and promotes students’ ability to transfer CT to other tasks and domains and to other contexts and situations. However, the positive development of students’ CT dispositions could not be demonstrated in this study, which can be explained by the short duration of this intervention
A Lightweight MES Using RAMI4.0 on the Example of Smart Insect Farms
No full textReference Architecture Model Industry 4.0 (RAMI4.0) compliant Manufacturing Operation System (MES) implementations require high investments, which put them out of reach for small and medium-sized enterprises. This work presents a lightweight RAMI4.0-compliant MES. The underlying proposed architecture of the Cognitive Robotic System for Digitalized and Networked (Automated) Insect Farms (CoRoSect) project ensures communication and information interoperability within the shop and office floor. The repository pattern is used for sharing data by integrating secondary Asset Administration Shells (AASs) as an information hub. We propose further enhancements by implementing higher-level AASs for edge or public cloud use. The path taken for reaching this goal can be especially interesting for Small and Medium Enterprises (SMEs) because of the simplified implementation and for other researchers by improving this procedure in a more complete solution. First, pilots show the practicality of the provided solution
TrainAR: An Open-Source Visual Scripting-Based Authoring Tool for Procedural Mobile Augmented Reality Trainings
No full textMobile Augmented Reality (AR) is a promising technology for educational purposes. It allows for interactive, engaging, and spatially independent learning. While the didactic benefits of AR have been well studied in recent years and commodity smartphones already come with AR capabilities, concepts and tools for a scalable deployment of AR are still missing. The proposed solution TrainAR combines an interaction concept, a didactic framework and an authoring tool for procedural AR training applications for smartphones. The contribution of this paper is the open-source visual scripting-based authoring tool of TrainAR in the form of a Unity Editor extension. With this approach, TrainAR allows non-programmer domain experts to create (“author”) their own procedural AR trainings by offering a customized editor, while at any time programmers may decide to utilize Unity’s full capabilities. Furthermore, utility and usability evaluations of several already developed TrainAR trainings (combined n = 317) show that TrainAR trainings provide utility in several contexts and are usable by the target groups. A systematic usability evaluation of the TrainAR Authoring Tool (n = 30) shows that it would be usable by non-programmer domain experts, though the learning curve depends on the media competency of the authors
