| Project Summary | The employment of industrial robot systems, especially in the automotive industry, led to a tremendous increase in productivity. Nonetheless, rising technological complexity as well as the crucial need for respecting specific safety issues pose new challenges for man and machine. The goal of this project was to develop algorithms, guidelines, and tools that make the commissioning of industrial robot systems more reliable by verifying the programs of robots and logical controllers. This in particular includes optimizing the schedule of the robot systems in order to ensure desired period times as well as conflict-free timetables already in the planning stage. We showed within our project that the Periodic Event Scheduling Problem proposed by Serafini and Ukovich (A mathematical model for periodic scheduling problems, SIAM Journal on Discrete Mathematics, 2(4):550–581, 1989) is well applicable to tackle the arising cycle time minimization tasks. We established a variant of the classical formulation in order to cover the special characteristics of our scenario and demonstrated how this key element can support engineers and programmers throughout the commissioning of real-world robot production systems. | |
