Two reachability graphs for the blade production model.
(a) Reachability graph for the blade production model with an initial marking with two tools and one core available. (b) Reachability graph for the blade production model with six tools and three cores available. Ovals represent states with the corresponding marking written inside. Directed arrows represent edges and correspond to an occurrence of transition t1.

Comparison of the state space of the models.
The lines represent the states spaces for the simulations of the A. coranica (yellow) and O. schinzii (black) models and the effect of deleting the transition ‘Back home’ associated with the location change from the O. schinzii model (blue). The state space size (vertical axis) is plotted on a log scale. The number of makers of each simulation (horizontal axis) is plotted on a linear scale.
