response to different products coming from upstream equipment. For both options, you
can designate the time required for the change to a particular product, as well as whether
operator intervention is required.
R EMARKS
The check box for changeover operators can be overridden by the Disable Operator
Constraints option in the Simulate module.
Suppose that loss occurs as the equipment and product is being produced according to a
production plan. If you want the production plan’s quantities to refer to the quantities of
good units actually sent downstream, reference the plan quantities as Good Units
Produced in this dialog box.
Reliability dialog
D ESCRIPTION
The Reliability dialog box allows you to define random downtimes (i.e., failures) for
machines, conveyors, or palletizers. You can define reliability logic using the expected
percent uptime of the equipment, the probability the equipment will not fail over some
period (i.e., Reliability Over a Time Span), or individual failure streams.
R EMARKS
The check box for repair operators can be overridden by the Disable Operator Constraints
option in the Simulate module.
During a failure, the state variable of the equipment is set to Failed and the
_FailureNumber variable is set to the Failure Number value (if using individual streams)
or “1” (if using Expected Uptime or Reliability).
Run Options dialog
D ESCRIPTION
The Run Options dialog box allows you to define the initial speed factor of a Machine or
Palletizer module.
R EMARKS
If the Initially Active operand is not checked, the equipment’s speed factor will be zero at
the beginning of the simulation run. Otherwise, specify the initial speed factor of the
equipment in the Initial Speed Factor field.
