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.
