A Simul8 shift pattern lets you say at what times of day parts of your simulation work. (If all of you simulation starts and stops at the same times then you do not need to use shift patterns - instead just set the clock to control the start time and length of each day).
To make use of shift patterns first set up a series of shifts (use Shifts button on the Data & Rules tab).
Click NEW to add each shift (for example you might want two shifts called DAY SHIFT and NIGHT SHIFT).
Click Detail if you want to change the time each shift starts and ends each day.
The Behavior Tab lets you say what should happen to Activities that are using Resources when those Resources are removed at the end of a shift.
Shift patterns can be used by Resources, Activities, Start Points and Conveyors.
