Illustration of the setting of parameters by the encoding of multiple levels. Properties like the multilevel variable can be edited in the variable editor. The parameter a (level of activation) default equals 1, and can be modified to encode multilevel logical operations. For example, in the toy model (see Figure 2), tf1 reaches a level 2 if both k3p1 and k3p2 are active. This is set up in ProMoT via a gate of the class AND where the output has a = 2).
