​To perform complicated assembly operations with your hands above shoulder level for a whole day is incredibly hard. The risk of quality defects is one of the consequences.​

Proactive assembly ergonomical and geometrical quality assurance for sustainable production (PEGASUS)

Vehicles are mainly manufactured by people who are expected to perform assembly operations of utmost quality during an entire workday. They need the best prerequisites to execute their work. Poor ergonomic conditions lead to 6-8 times more errors as good conditions. This leads to increased costs - up to 10 times the original cost if corrected in plant and another 12 times if corrected on market.

This project will explore how assembly ergonomics and geometrical quality are related to each other with in-depth analyses of complexity criteria affecting quality outcome.

Our goals are:

  • Facilitate a more complete robustness analysis and ´total-robust´ systems that are ecologically, economically and socially sustainable.
  • Develop a validated model for predictive assessment of assembly complexity, weighting the factors affecting quality outcome the most.
  • Develop a method for geometrical stability analysis including complexity and other assembly ergonomic factors.
  • Develop validated demonstrators.
