Bokkapitel (refereegranskat)abstract
- Vi upplever att många studenter har svårigheter med att ”knäckakoden” (läs: lära sig programmera) och då inte bara i introducerandekurser utan också i fortsättningskurser i programmering. Som ettförsta steg till att motivera studenterna till att lära programmering harvi för kursen JavaScript för webbutveckling introducerat skapandet avspel som examinationsuppgift. I kapitlet beskriver och diskuterar vivarför och hur vi introducerat skapandet av tre-i-rad somexaminationsuppgift och vilka erfarenheter vi tar med oss för vidarekursutveckling. Som huvudargument för att introducera spel lyfter viatt motivera studenterna till att lära sig programmering. Vidarediskuterar vi att detta kan vara möjligt genom att öka ”kulfaktorn” ochdå samtidigt ta avstamp i något studenterna känner till och kanreferera till. Vi upplever att spel som examinationsuppgift är något sommottagits som positivt av studenterna men att ett flertal utmaningarkvarstår. Bland annat upplever vi att flertalet studenter har svårt medatt ”sy ihop” delarna till en helhet (att gå från ”ax till limpa”) samt attdet är mycket stor spridning på kvalitén på inlämnade lösningar.

Distribuerad och synkron laborationshandledning i Zoom : Möjligheter för återkoppling i en programmeringskurs
- 2022. - 1
-
Ingår i: Bidrag från universitetspedagogisk konferens 2021. - : Karlstads universitet. - 9789178672974 - 9789178673087 ; , s. 29-46

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Att använda Zoom för distribuerad och synkron laborations-handledning inom programmeringskurser, kan vid en första anblick ses som ett tillvägagångssätt utan några större utmaningar och problem. Men vid en andra anblick har flera utmaningar och problem identifierats. I föreliggande kapitel beskriver författarna därför hur de använt Zoom som plattform för distribuerad och synkron handledning på kursen Serverprogrammering i JavaScript. I huvudsak har två övergripande erfarenheter utkristalliserat sig ur denna användning vilka i föreliggande kapitel benämns som: 1) Notifikationer för co-host och endast en plats i kön, och 2) Avsaknad av återkoppling. I kapitlet behandlas dessa två erfarenheter utifrån utmaning och implementation. Som ett förslag på lösning för dessa två utmaningar föreslår författarna att ett kösystem implementeras. En kösystemsprototyp har också utvecklats och beskrivs i detalj i kapitlet. Författarna ser en hög potential i kösystemsprototypen både som den är utvecklad i dag och för framtida förbättringar med ny funktionalitet. För framtida utvecklingsarbete kommer därför också kösystemsprototypen att utvärderas både vad det gäller användbarhet och funktionalitet.

- In a competitive market, organizations expand their supply chain on a global scale. Pressure from customers, stakeholders, legislation and environmental organizations have pushed companies to be more considerate of the environmental impacts of their supply chain. This development has put focus on sustainability within supply chains, leading to the rise of Green Supply Chain Management (GSCM). The purpose of this research is to create a conceptual model to present the vastly varied literature within the area of GSCM in a structured way, in order to promote environmental and in turn, overall supply chain performance. The research methodology includes a literature review using 125 peer-reviewed journal articles from 2013 to 2016 published in 19 journals. Out of the 125, 10 journalarticles were selected based on their focus in regard to the subject. The articles were chosen to attain a vantage point in view of critical factors within environmentally sustainable supply chains with a focus on optimizing performance. This paper contributes to theory by presenting a conceptual model for optimizing performance in green supply chains. Drivers, which promote Green Supply Chain (GSC) are classified as re-active and pro-active, and the main methods used for optimizing performance are concluded to be collaboration, metrics to monitor performance and practices such as green purchasing, ecodesign, reverse logistics and legislation. The review may be of use to both academics and companies as it outlines proven ways to implement green supply chain with high performance.

Smart manufacturing support to product platforms in industrialized house building
- 2019
-
Konferensbidrag (refereegranskat)abstract
- Swedish house building companies currently face many challenges in terms of fluctuating market demand, need for flexible product offering, non-uniform governmental regulations, high costs, and long lead times. These challenges affect both internal and external efficiency of companies. Product platforms have been used for more than a decade in this industry to improve both internal and external efficiency. However, the industry is still criticized for its inefficient and costly process. Smart manufacturing has emerged as means to improve the efficiency of internal processes and the question is if and how smart manufacturing can complement and support product platforms in industrialized house building. The aim of this study is to explore the potential of smart manufacturing to complement and support product platforms in theory and practice in the context of industrialized house building. A literature review and a multiple case study were chosen to fulfill the study objective. In total fourteen semi-structured interviews were conducted in two timber house building companies. The data was analyzed within and across cases using four platform assets for categorization: components, processes, knowledge and relationships. The results show that the smart manufacturing technologies are in both theory and practice mainly supporting the process platform asset through developing vertical and horizontal IT systems integration, definition and digitalization of flexible building systems, and transferring explicit drafting and engineering knowledge into parametric modelling tools.

Konferensbidrag (refereegranskat)abstract
- In Sweden, wooden single-family houses have been prefabricated for a long time, instead of being built on-site. However, it was mentioned that in several firms, many working tasks just were brought from outside into a manufacturing hall, yet the tasks were not adjusted to utilize potential benefits that prefabrication offers. Production development was not prioritized and thus, the firms’ productivity and efficiency were on a second-rate level, with profitability numbers following accordingly. In the past years, however, and especially related to the rapid development within the areas of digitalization and automation, several firms have been investing into different types of development. As the production of wooden single-family houses is very unstable in the past decade, yet, production costs per m2 more than doubled since 2002 and the industry is characterized of a very high degree of competition, productivity is a key performance indicator (KPI) in this industry.The aim of this study is to investigate in the productivity of Swedish firms producing wooden single-family houses in the past ten years. This is done by using the activity ratio Total Asset Turnover ratio, measuring a firm’s operational efficiency from 2008 to 2017, i.e. the latest data available. For 47 firms, data from annual reports were collected and analyzed.Data shows a productivity loss by 4.7%, aggregated for all firms in the industry. Further, the productivity for individual firms developed very different, varying from +141.7% to -68.4% and it can be concluded that a change in fixed assets affects productivity.

Konferensbidrag (refereegranskat)abstract
- In this paper, focus is on information management in the wooden single-family house industry i.e., one segment of the construction industry. So far, there is lack of research that investigates possible paths for information management in the wooden single-family house industry. The purpose of this paper is to overcome this limitation, and to increase the knowledge on how to mitigate the challenges of information management in the wooden single-family house industry. Two research questions were formulated: RQ1 What are the challenges with information management in the wooden single-family house industry? RQ2 What are the potentials of traditional BIM, BIM for OFC, and PLM to respectively mitigate the information management challenges? The results presented in this paper are based on a case study at a wooden single-family house company and a literature review on information management. In total, eight empirical information management challenges were identified at the case company, categorized into technology-related, process-related, or people-related challenges. Based on the analysis, it was concluded that a PLM-system has larger potential to mitigate the information management challenges in the wooden single-family house industry than traditional BIM and BIM for OFC. This paper contributes with insights on challenges of information management in the wooden single-family house industry and the potentials of traditional BIM, BIM for OFC, and PLM to mitigate these challenges. The results from this paper can support managers in the house building industry with understanding the potentials of traditional BIM, BIM for OFC and PLM for specific information challenges and facilitate decision making on what actions to take to improve their information management.

- The housing industry faces challenges in product data management, resulting in negative effects on productivity, efficiency, and quality. The purpose of the study presented in this paper is to elaborate on requirements and functions of a support system to mitigate challenges with product data management in the wooden single-family house industry. As a support system, a pilot product lifecycle management (PLM) system was developed with functions to fulfill the requirements. The support system was installed and tested in a real-world setting, a wooden single-family house company, Company T. The paper contributes with the insights that a PLM system for industrialized house building can be developed, fulfilling the requirements in this specific industry. The functions developed were perceived to have value and could, for Company T, mitigate their challenges with product data management. The support system facilitate integration between the pilot PLM system, the building information modeling tool and the enterprise resource planning system at Company T. Based on the study carried out, the paper concludes that a PLM system is feasible, and that it might be a way to mitigate challenges with product data management in the wooden single-family house industry.

Ingår i: Procedia Manufacturing. - : Elsevier. - 2351-9789. ; , s. 459-470
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- To remain competitive, single-family wooden house builders might create smart wooden house factories. Smart factories and smart production are recent concepts used to denote ideas that support competitiveness in for example the automotive industry. In the housing sector, a concept introduced to increase competitiveness is industrialized house-building. The aim of the study presented here was to investigate whether industrialized house-building characteristics could be a step toward a smart factory for wooden house builders. In this paper, ideas of the smart wooden house factory are synthesized, and challenges for the single-family wooden house builder are identified. The study is founded on empirical data from one single-case study. A challenge identified was the maturity level of the culture and organization to commit to and utilize modern technology and modern working methods. The concept of the smart wooden house factory is still in its infancy and needs further research.
