Reihenfolge von Fertigungsaufträgen mittels Quanten Annealing

In August, the project "Use of quantum annealing for sequence planning in manufacturing companies - QuantPro", funded by the Rhineland-Palatinate Ministry of Economic Affairs, Transport, Agriculture and Viticulture, came to an end. In the project, the sequence of production orders was calculated using quantum computers (quantum annealers). The use of quantum annealing made it possible to efficiently realize short-term rescheduling in particular due to the shorter calculation times compared to conventional methods. The figure shows an example of the procedure for such short-term rescheduling using quantum annealing. To evaluate the method required for this, planning data from industrial partners was analyzed and calculated. Despite the currently still limited hardware capacity of quantum annealers, it has already been possible to improve the solution quality and shorten the calculation time in direct comparison with conventional calculation methods.
