abstract = "Automated assembly lines are subject to unexpected
failures, which can cause costly shutdowns. Generally,
the recovery process is done 'on-line' by human experts
or automated error recovery logic controllers embedded
in the system. However, these controller codes are
programmed based on anticipated error scenarios and,
due to the geometrical features of the assembly lines,
there may be error cases that belong to the same
anticipated type but are present in different
positions, each requiring a different way to recover.
Therefore, robustness must be assured in the sense of
having a common recovery algorithm for similar cases
during the recovery sequence.
The proposed approach is based on three-dimensional geometric modeling of the assembly line coupled with the genetic programming and multi-level optimization techniques to generate robust error recovery logic in an 'off-line' manner. The approach uses genetic programming's flexibility to generate recovery plans in the robot language itself. An assembly line is modeled and from the given error cases an optimum way of error recovery is investigated using multi-level optimization in a 'generate and test' fashion. The obtained results showed that with the improved convergence gained by using multi-level optimisation, the infrastructure is capable of finding robust error recovery algorithms. It is expected that this approach will require less time for the generation of robust error recovery logic.",
