Design Automation for Smart Factories

Rethinking the design foundations of high-assurance intelligent manufacturing systems

The paper titled A Hierarchical Modeling Approach to Improve Scheduling of Manufacturing Processes, authored by Sebastiano Gaiardelli, Stefano Spellini, Michele Lora and Franco Fummi, has been accepted at the 2022 IEEE International Symposium on Industrial Electronics (ISIE)

Timely response to sudden production events and requirements shifts is a key feature of Industry 4.0. It requires techniques to manipulate and optimize the production processes, and components providing an high degree of reconfigurability.

To acknowledge to such demands, this paper presents a multi-level and hierarchical approach to manufacturing processes modeling. Models are structured to represent the production hierarchically: partitioning recipes in a set of tasks, allocated to machines’ manufacturing services and expressed as a sequence of elementary actions. Then, we propose a run-time scheduling algorithm able to exploit the novel structure given to knowledge by the proposed modeling approach. The algorithm aims at minimizing the makespan while maximizing machines utilization.

We validate the contributions of this paper on a full-fledged production line. The modeling strategy has been implemented in SysML: a well-known systems modeling language. The experiments show the presented model and the proposed scheduling approach enabling a more precise and more performing control over the manufacturing process.
