Björn Johansson performs research on sustainability aspects using virtual tools to analyze and improve production systems for industries. The goal is to create and improve production system performance in order to strive towards a more sustainable future in terms of less environmental impact, socially sound workplaces as well as a healthy economy. The results from the research aims at facilitating use of methodologies and tools for engineers to use while analyzing and creating production systems. Example of application areas are: - Simulation of complete product lifecycles. - Dynamic analysis for evaluation of environmental aspects of production systems. - Realistic 3D animation of production equipment, facilities and environment. - Layout planning, scheduling, balancing etc.
