Operation Id:

Obligatory numerical field (3 characters at the most). This field is completed with zeros. If the number exists data is displayed.

Description:

Operation description, optional field.

Work center Id:

This the code of the work center on which the operation take place (obligatory). This code must figure in the work center list. If it is found, its description is displayed.

(All the times are expressed in hours with four decimals).

Mach. Setup Time:

Machine Setup time: this is a fixed time, independent of the size of the manufactured batch, necessary to change the set of tools and proceed to the machine setup.

Labor Setup Time:

 Labor time required for machine preparation: this is the number of labor hours needed to prepare the machine during the time indicated above. If two people are required to prepare the machine, you must enter double the machine setup time

Machine Run Time:

This is the machine occupation time required to manufacture the quantity of parts (indicated in the Quantity of time field) multiplied by the quantity of parts indicated in the Quantity by cycle field.

Labor Run time:

 This is the labor occupation time required to manufacture the quantity of parts (indicated in the Quantity per time field) multiplied by the quantity of parts indicated in the Quantity by cycle field. The direct labor time may be different from the machine time if an operator deals with several machines in the same time. The direct labor time will then be equal to the machine time divided by the number of machines looked after. Or, if several operators are required to lead a machine the direct labor time will be equal to the machine time multiplied by the number of operators.

Both of these times let you specify the number of operators working on one machine:

-  if two operators work on a machine, you must indicate the machine time multiplied by two in the Labor Run Time field.

- If an operator works simultaneously on two machines, you must indicate the time equal to half of the machine run time.

Quantity per Time:

Number of machine cycles realized in the time specified above.

This field lets you express manufacturing times as flow rates: if you indicate a machine time of 1 and a quantity of time of 165 this means that the machine time per piece is 1/165^th of an hour.

You can also, for instance, indicate a time in seconds: type in the fields “machine run time” and” labor run time the number of seconds to complete the operation on one part and “3600” in the field “Quantity per time”.

Quantity per Cycle:

 Number of parts produced in one machine cycle.

You enter the number of parts manufactured during a machine cycle. The unit machine time by part is therefore equal to the machine time divided by the length of time and by the quantity by cycle. Same for the direct labor time.

Move time:

This is the time required to transfer parts to the next operation; it is used for the infinite and finite capacity scheduling.

For the subcontracting work centers, this time is indicated in number of days. This is the total time required to complete the operation.

Fixed Scrap:

 Fixed quantity scrapped each time the operation is performed. It represents the wasted quantities while machine setup and production starting.

Proportional Scrap:

 Proportion of parts scrapped during the operation.
Note: it is entered as a percentage with two decimals (ex : 5.60 = 5.6%).

Reporting:

 At the basic level, all the operations are counting points.

You specify here how the operation should be reported. You must choose one of the  three options:

Undeclared Operation: these operations will not need to be reported; they do not appear in the Production Reporting window. They are considered as completed as soon as the previous operation is done. Times used are equal to standard times. No scrap can be entered.

Counting point: these operations will have to be reported through the Production Reporting window. Quantities good and rejected must be entered as well as times used.

The last operation of a routing must be a counting point.

Counting point with automatic imputation: in that case, only the quantities have to be entered, the times used are equal to standard times..

Overlapping:

 Here, you may define the overlapping method between one operation and the next:

None: no overlapping is allowed.

01- Anticipated setup (the setup of this operation is started whereas the batch has not arrived at the work center.)

10- Simple overlapping (the setup is started when the first transfer batch has arrived on the work center.)

11- Anticipated overlapping and setup (the setup is started so that the production can start when the first transfer batch arrives on the work center).

Machine:

 Here you may specify the machine to use. This field is optional. If you do not specify a machine, the corresponding operations can take place on any machine of the work center.

Tool:

 Specifies which tool is required to complete the operation. The tool code must be defined in the Tool table.

Comment:

Free comment.

Library

 Displays the list of library operations. If you select en operation in the list, its data are copied in the fields of the operation window.

Destinations

 In case of network routings, enables to specify the standard part dispatching to their next operation.

Costs

 Displays the operation costs by cost category. They are calculated by the Routing Costs Calculation function.
