Production resettings is a vital element of production flexibility and optimizing the setup tasks scheduling within a production channel is required to improve production rate. This paper deals with a NP-Hard production resetting optimization problem based on an industrial case. In this paper we present how to hybrid a Branch-and-Bound method for this problem with a genetic algorithm. The idea is to use the genetic algorithm to improve the upper bound and thus speeding up the Branch-and-Bound while the genetic algorithm uses the content of the Branch-and-Bound stack to reduce its search space. Both methods are running in parallel and are therefore collaborating together.
