Sammanfattning
The concept of digital twins is a popular subject within the production industry and during the last couple of years it has been expanding with the help of Industry 4.0. This thesis evaluates the concept and the technology behind digital twins for the smart factory. It examines the different definitions of a digital twin, how far the technology has come, and what is required by small and medium-sized companies in the production industry to implement and create digital twins. A case study was conducted to increase the understanding of the creation process for digital twins which together with a literature study and interviews have been used to answer the research questions formulated in this thesis. It was found out that the digital twin is a complex concept still in an early stage of its maturity with divided opinions among different professions and academia of how it should be defined. A compiled definition of digital twins within the production industry is proposed together with an estimation of the technology’s readiness level, as well as guidelines for implementing and creating a digital twin for small and medium-sized companies within the production industry.
