Features

 

Crew Operations

Labor-paced operations can be defined as crew or non-crew.  Crew operations are scheduled independently of crew size (that is, number of persons required).  Individual crew members will not record the quantity completed at a crew operation; this is done by the crew reporter for the entire crew.

Effectivity Dates

Routing effectivity can be expressed for all types of operations. This indicates when a particular routing comes into effect (that is, when the operation can first be performed) and/or when a routing goes out of effect.  Operations may always be in effect; may come into effect on a specified date and then always remain in effect; or may always be in effect until a specified date.

If the date on which a specified operation comes into effect (in-date) is before the date on which it goes out of effect (out-date), then the routing is in effect between those dates.  If the in-date is later than the out-date, the operation is not in effect between the two dates.

Copy Routing

The copy routing facility enables the routings for one part to be copied to another, either within a plant or across plants.  Either all or selected routings may be copied.  An effectivity in-date may be specified for each of the copied routings.

Copy Workcenter

The copy workcenter facility enables you to copy one workcenter, a range of workcenters, or all workcenters within or across plants.  This conversation saves you time if many workcenters need to be defined when MAC-PAC is installed or if new, similar workcenters need to be established across or within plants.

Sensitivity Flag

Field is used to indicate whether an operation is truly 'fixed' or fixed as a function of batch quantity.  For example, quarantine is truly fixed whereas mixing 100 lb. increments is fixed as a function of batch quantity.

Sensitivity Factor

Percent entered for operations that are fixed as a function of batch quantity.  The percentage indicates at what point an additional batch quantity will be ordered.  The following formula is used:

Number of Batches = Order Quantity - ((Sensitivity Factor / 100) * Batch Quantity)
                                                      Batch Quantity

Result is always rounded up for any remainder.

Note:    If the preceding scheduled operation is fixed time (operation is 6 or 7) or outside processed (operation type is blank), operation type 4 is treated as operation type 3, and operation type 5 is treated as operation type 1, because of the nature of fixed time operations.
