public class TimeTable
extends Schedular

A timetable is a list of events, with imposed dependencies. Timetables can be connected to a physical model of moving objects In MOCHY V 1.0, this physical model is a Stochastic Petri net Each event is the timetable description of a physiscal event occurring in the physical model This has two consequences during a joint simulation occurrences of physical events which are listed in the timetable fix the date during TT simulation when the current date has passed the date of a realizable event in the table it "allows" the corresponding event in the physical model

returns the list of minimal events for a timetable

Specified by:

minList in class Schedular

Returns:

minListUnexecuted

public ArrayList<TableEvent> minListUnexecuted()

returns the list of minimal events that are not yet executed in a timetable we search every event that has only executed predecessors
