The Lost Production percentage can be changed dynamically using a Change Lost
Production of Equipment action.
Operators dialog
D ESCRIPTION
The Operators dialog box defines the operators required for the processing and delay of a
particular activity. These activities include changeovers (specified in Production and
Changeovers dialogs), failures (specified in Reliability dialogs), and scheduled stops
(specified in Scheduled Stops dialogs). An activity does not begin until all operators are
available simultaneously. Priorities may be given to separate activities using the Priority
field.
The operators for a given activity may include individual operators or members from
operator sets.
R EMARKS
Individual operators are defined in the Operators module, and operator groups are defined
in the Operator Groups module.
The Operators repeat group determines the operators required for the processing and
delay of the activity. All operators must be available and allocated simultaneously for the
activity to begin. After the delay time of the activity, the operators are automatically
released.
When an operator becomes available, the Priority field for an activity determines the
activity to which the operator will be allocated if more than one activity is waiting for the
operator. Activities with lower-value priorities are serviced before activities with higher-
value priorities. If multiple activities with equal priorities request the same operator, the
activity with the longest waiting time is allocated the operator. The Priority applies to all
operators listed in the Operators repeat group.
For example, suppose there is a failure at Machine 1 with a priority of 1, and a failure at
Machine 2 with a priority of 2. If both failures require the same operator, and the operator
is currently busy, the operator will be allocated to the failure at Machine 1 when the
operator becomes available.
After an operator is allocated to the activity, it is assigned the Operator State specified.
The default state is Working, but may be changed to reflect either the type of activity (i.e.,
Working on Failures) or the machine/equipment (i.e., Working at Machine 1).
