5. The basic characteristic of arcs is their multiplicity (cardinality). By default, the multiplicity of every arc is one. That can be changed to any discrete number. How is multiplicity changing enabling and firing rules?
Firing rules:
1.)Input places have to contain at least as many tokens as the
the multiplicity of the corresponding input arc.
2.)Transition removes as many tokens from input places as the cardinality of the corresponding input arc
3.)Transition creates as many tokens in output places as the cardinality of the corresponding output arc
