Transitions, Actions and Transition-Conditions

Steps, Transitions and Actions

Transitions, Steps and Direct Links

Transitions, Steps and Transition-Conditions

A transition-condition (receptivity) is every logical function associated to each

Step

Transition

Action

Structure

A transition-condition is

all the logical functions associated to each step

always true

all the logical functions associated to each transition

all the logical functions associated to each step and each transition

When a transition is enabled and the associated condition is true, the transition is not cleared.

True

False

A predicate is a logical expression with one or more variables.

True

False
