Globalization, digitalization and rapid development of technology have made supply chains more complex than ever before. Complexity has forced many organizations to outsource their warehouse activities to Third-Party Logistics service providers. They, in turn, deploy automatization solutions and tools such as warehouse management system (WMS) software to manage in-house logistics services. However, research into third-party logistics (3PL) and WMS has so far been scarce, especially, regarding WMS and its sustainability supporting aspects. Large-scale outsourcing has recently received increasing attention from high-level decision-makers, in particular as regards the overall sustainability of logistics-related actions and processes. This systematic mapping-based study examines the current state of the art of academic literature considering WMS and its intersections with topics related to sustainability. As a result of the specific focus of the work, only a small set of 22 studies was found to add value to the topic, which opens up additional research opportunities in this direction. The majority of the studies were journal articles (13) rather than conference papers (9). The most frequently used keywords in these studies addressed the topics of WMS, ICT, sustainability, warehouse technology and operations. The content-based analysis revealed five main thematic areas, namely, WMS concept development, optimization and improvement, Internet of Things (IoT) and Industry 4.0, safety, and sustainability. Surprisingly, only one publication was devoted purely to WMS and indices built on the triple bottom line approach. The study considered neither the functions of WMS, nor sustainability-related features of WMS. The remaining studies discussed sustainability mainly from the safety perspective. It is concluded on the basis of this study that there are significant opportunities for further research in WMS and sustainability.

Following recent advancements in automatic speech recognition (ASR) technologies, we replicated an experiment four decades ago that utilized voice as an input modality for computer programming. We also extended this experiment by investigating the pedagogical effectiveness of ‘programming by voice’ in terms of attitude, self-efficacy, code correctness, and coding speed. A total of 96 students from an institute of technology in the capital region of the Philippines were randomly selected to participate in a quasi-experimental study using a one-group pretest-posttest design. We subjected students to programming activities with different levels of difficulty to compare voice and keyboard. Our results show that although voice decreases negativity, it likewise decreases control, which means that both attitude and self-efficacy are positively and negatively affected, respectively. Using voice as an input modality also allows students to code faster when the activities are easy but not when they are moderate or difficult. Code correctness analysis shows that voice is only preferable for easy and moderate machine problems. With the deviation of our findings from an experiment four decades ago, we can now conclude that ASR technologies and voice as input modality provide substantial implications and new opportunities for teaching and learning computer programming.

This paper presents a web-based operational model which improves the visibility of inventories in a subcontractor network to the manufacturer, and consequently, reduces the supply risk for the manufacturer. There is a need for a new operational model because the supply problems in a subcontractor network disrupt the activity of the manufacturer. In practice, the manufacturer sees these disturbances especially as an increase in production costs, but they also impact the manufacturer's product sales because delayed delivery to end-customers leads to potential losses in sales. The operating model developed offers the manufacturer advance information on the possible supply problems of subcontractors. Consequently, delays in deliveries can be reduced or better anticipated. At present, subcontractors in the supply chain studied mainly manage inventory and production information with Excel, and transfer information by e-mail. A centralised, web-based system would make the activity more...

In sports, too little attention has been paid concerning why changes are important for personal development and who exactly should notice when a change in personal activities would be needed. People themselves do not necessarily recognize that their efforts and goals are not in good sync. When this happens, they make changes to their routines, when things go badly wrong, but at the same time they can be blind for their inefficient ways of working. Authors have created a framework to ease the issue to identify a need for change to achieve sports goals. The research focused into the forefront of change management: Identifying and acknowledging need(s) for change, especially in initial stages of individuals change needs detection phase. As result, we propose Identify, acknowledge, and make a courageous move framework. With these stages, one can elicit appropriate changes. The value of the study lies in an overall and profound examination of the initial stages of sport training related change management.

Different monitoring methods for the laser additive manufacturing process were studied in this study. Possibilities and downfalls of three different methods were compared to each other to define their applicability in future on-line and adaptive monitoring use in LAM processes. The material used on all the LAM process tests was EOS StainlessSteel PH1 in fine powder form. In this study, e.g. parameters like scanning speed, layer thickness and hatch space were tested. Based on the results of this study, the pyrometer seems to be more easily adaptable to continuous monitoring than the spectrometer or systems based on active illumination imaging system. It seems that the pyrometer is a promising method for quality control. The ability to control quality through on-line measurements can be further utilized in future e.g. for on-line quality control and dynamic process control, i.e. the ability to change and correct parameters on the fly.

In August 2018, the City of Kuopio, student apartments (Kuopion Opiskelija-asunnot Oy), regional waste management and recycling company (Jatekukko Oy), and Savonia University of Applied Sciences set up an event called 3R Game Jam. The aim of the event was to different sources of motivation, which could improve young adults’ interests towards recycling. Additionally, the goal was to study gamified solutions, designed to boost recycling activities within the students age group. The game called “Fox the Recycler” won the competition and was selected for further development. In the fall of 2018, the next version of the game was piloted in student apartments where 90 % of all young adults (250) installed the game. The best rate of monthly users was 235, daily users over 50 to 30 persons. After the pilot, the recycling rate of biowaste increased from 76 % to 97 %. The recycling rate of plastic also increased significantly: 84 % of the inhabitants currently recycle plastic, while only 25 % of them did so before the pilot. The study found that the gamification-based solutions can be used efficiently to support a change in consumers’ behavior. such solutions have a wide range of applications in many different recycling and other contexts, and in different environments. The 2.0 version of the game will be piloted for primary school children to further study educational and cultural change in recycling during 2019.

Education is changing rapidly towards digital and online forms in universities. E.g. digitalization and Massively Open Online Course (MOOC)s evolve remote education tools, which changes the teaching approaches. Covid-19 accelerated digital transition from classroom-based education towards hybrid models, then online classes and finally to fully online education. While the education has moved from classrooms to Internet environment, the suitability of this transition has not really been evaluated. This is especially important to teamwork based courses in which the collaboration within teams and between teams is considered a major part of the learning outcomes of the course. Our study presents experiences on transforming a set of software engineering courses from a fully onsite course to a fully online course and lessons we have learned on that transition. We analyze hackathon and capstone style courses for traditional and remote execution modes. We have used hackathons for decades and have experience of different types of implementations. For capstones we have two different courses that we have experience with. Analyzing the team-based courses shows focal points which area hard to solve with online approaches. Online environment does not only make students faceless to the teacher but also to other teammates. This is especially visible in the long-lasting capstone courses.

Background: With the continuing growth of warehouses globally, there is an increasing need for sustainable logistics solutions in warehousing, but research linking warehouse management systems (WMS) and sustainability is lacking. Methods: A systematic literature review and bibliometric analysis were conducted in Scopus and Web of Science databases from 2006 to 2022 to investigate academic knowledge of WMS contributing to warehouses’ social and environmental sustainability. Results: Findings revealed only 12 topic-relevant articles from 2013 to 2022, primarily published recently. More recent articles have received more citations than earlier published works. The articles were from multiple research fields, such as business economics, engineering, computer science, and social sciences, with only one article on environmentally sustainable technologies. The top keywords were “warehouse management system”, “internet of things”, “industry 4.0” and “supply chain”. Only six articles had env...

This study examined the association between digital transformation (DT), supply chain integration (SCI), and overall sustainable supply chain performance (OSSCP). The current literature has preliminarily explored the concepts of DT and SCI and their relationship with sustainable supply chain performance. However, real empirical evidence of the direct impact of DT and SCI on OSSCP has been missing so far. To fill this gap, data were collected from 134 professionals working in international manufacturing companies operating in Morocco through a questionnaire-based survey from August 2022 to November 2022. A conceptual framework was developed based on DT, SCI, and OSSCP and analyzed by partial least squares structural equation modeling (PLS-SEM) with the assistance of SmartPLS 4.0 software. The findings revealed that DT has a significant positive influence on SCI and OSSCP. Furthermore, SCI directly and positively impacts OSSCP with a partial mediation effect on the relationship betwee...

PurposeRobotic process automation (RPA) has recently emerged as a technology focusing on the automation of repetitive, frequent, voluminous and rule-based tasks. Despite a few practical examples that document successful RPA deployments in organizations, evidence of its economic benefits has been mostly anecdotal. The purpose of this paper is to present a step-by-step method to RPA investment appraisal and a business case demonstrating how the steps can be applied to practice.Design/methodology/approachThe methodology relies on design science research (DSR). The step-by-step method is a design artefact that builds on the mapping of processes and modelling of the associated costs. Due to the longitudinal nature of capital investments, modelling uses discounted cashflow and present value methods. Empirical grounding characteristic to DSR is achieved by field testing the artefact.FindingsThe step-by-step method is comprised of a preparatory step, three modelling steps and a concluding s...
