Run Setup dialog box- Simulation Time tab

Simulations sometimes use compressed time because all of the activities are performed within a regular time span. If you want to analyze any time that falls outside regular time spans, use calendar time.

iGrafx may only simulate from 00:00:00 1/1/1970 to 03:14:07 1/19/2038 in calendar mode and starting by date.

Element

Description

Compressed

Simulates only the active hours. The simulator only runs during the hours when activity occurs.

Calendar

Simulates both active and non-active times in the 24-hour schedule. Allows for regular activity time plus overtime or multiple shifts of resources.

Default Schedule

Choose a predefined or user-defined schedule during which the simulation is active for Calendar time. This schedule becomes the default schedule that any activity, generator, or resources references from any place in the model that uses a schedule.

Simulation Start

For simulations running in Calendar time, Simulation Start defines exactly when the simulation begins running.

Click the Change button to change the run start day or date.

For simulations running in compressed time, simulation begins when the first transaction is introduced.

Simulation End

Defines exactly when the simulation stops running.

Transactions complete- All transactions finish or at least advance as far as the process flow allows them.

Custom- The length of time that the simulation runs.

Time Conversion

Used to calculate the durations for activities, interarrival generators, and, in the case of compressed time, report elements.

Compressed Time- The default units for a compressed time model are 8 hours a day, 5 days a week, and 22 days a month. If you change the default units, it affects calculations of durations, interarrival generators, and report results.

Calendar Time - Report statistics are calculated using the standard time conversion units for calendar time models (24 hours in a day, 7 days in a week). Select Custom to change time conversion units. If you change these units, it can affect calculations of durations and interarrival generators, but not report results.

Warmup Time

Custom–Set parameters for a warm-up period. You may allow the simulation to run without data collection for any value of time that is less than the simulation end time. Be sure to extend simulation run time long enough for steady state data collection.
