Abstract
The development of a Petri net model in food industry is the topic of this document. In particular, the production of mycelium seeds of common mushroom (Agaricus Bisporus) is addressed. This product constitutes an essential first step in the cultivation of common mushroom. The model covers all the stages in the manufacturing of mycelium, detailing shared resources, conflicts, duration of tasks, as well as the amount of stored raw materials. As a consequence, the Petri net model is appropriate for decision making support by means of simulation and what-if analysis or optimization. The model is also suitable for structural analysis. Applying this model, it may be possible to improve the knowledge of the behavior of the production facility, as well as to identify bottlenecks, deadlocks, to quantify the number of common resources required, and to find out optimal or quasi-optimal assignment of resources to the different production tasks.
