An event is an individual happening, taking place at a given moment. Each event is indivisible and instantaneous. The event execution is defined by its event type.

Discreteness is a property of an event stating that the changes in the state could be counted (i.e. changes are discrete in the mathematical definition).

Each event defines following outputs:

• a simulation state update regarding the event that happened.

• a list of events that should be inserted in the future events.

• some events that are postponed.

• some events that are cancelled.

• See the entity

An event type: The event type is used to define what event execution will happen.

Event structure is a map with at least two keys:

• type a the event type as found in evt-type-priority.
• date as a date.
