Creating a Resource - Clean-in-place Tab

To open the Resources overview window, select > .

Click New at the bottom of the Resources overview window.

In the dialog box, enter a unique code for the new resource and click OK.

In the Resource Entry window, click the Clean-in-place tab. In this tab you can define CIP rules for the resource.

To add a CIP process step, click the Plus button at the top right of the tab.

In the New CIP Rule dialog box, specify these settings:

Select the name of the CIP process step that is used to create the CIP batch with the default step quantity.
If no value is displayed in the list, ensure that these conditions are met:
- A process step of CIP stage type is defined for this resource.
- This step is not already used by another rule for this resource.

Select the type of rule for scheduling the CIP batches.

Rule	Description
Absolute time	You can use this rule to schedule a CIP batch after the time T when this condition is verified: The duration T minus the start of a batch that follows the last CIP batch exceeds a specified duration.
Number of batches	You can use this rule to schedule a CIP batch after a specified number of batches since the last CIP batch.
Processing time	You can use this rule to schedule a CIP batch when the sum of the process segment durations since the last CIP exceeds a specified duration. Processing time is used to schedule a CIP batch after the resource has been used for a specified amount of time. Unlike absolute time, processing time does not count the resource's idle time, for example, the time between process batches.
Quantity	You can use this rule to schedule a CIP batch when the sum of the batch quantities since the last CIP exceeds a specified quantity.
Transition cost	You can use this rule to schedule a CIP batch when the sum of the transition costs since the last CIP exceeds a quantity. If the duration or quantity of a batch is not important, but specific events require a CIP batch, you can use a cost matrix for modeling. Each batch contributes to the sum of the transition costs since the last CIP. The contribution of a batch is determined by its changeover cost to the batch that follows it. The cost of the first batch on a resource is determined by the gauge cost, or zero if no gauge cost is specified. The cost of the last batch on a resource is the transition of its criterion to NONE.

Examples:

To schedule a CIP batch after eight hours of resource utilization, specify Processing time.
To schedule a CIP batch once a day, specify Absolute time.
To schedule a CIP batch after 25 batches, specify Number of batches.

If you have specified the Transition cost rule type, select the cost matrix to be used. The displayed cost matrices are the cost matrices that are available on the resource. You can select cost matrices for the resource on the Changeover tab of the Resource Entry window. Setup cost is not supported.
Specify the lower and upper limits of the rule.
For example, if you have specified number of batches as the rule type, specify the minimum and maximum number of batches.
- The minimum duration, number, or quantity specifies the minimum number of process batches that must be scheduled after a CIP batch.
- The maximum duration, number, or quantity specifies the maximum number of process batches that can be scheduled after a CIP batch.
If you have specified the Absolute time or Transition cost rule type, you cannot specify a lower limit.

If you specify 0 for the lower limit, the minimum constraint is ignored. If you specify another value as the lower limit, a number of batches are required after the last CIP, or CIP gauge time when no CIP batch is yet present.

If you have specified the Transition cost rule type, a CIP batch is scheduled before the maximum cost exceeds the sum of the transition costs between batches that have run after the last CIP batch.
If you want a large changeover to count as a CIP batch, select Large changeover replaces CIP. Specify the minimum changeover duration that can count as a CIP batch.
If this option is enabled and a minimum changeover duration is defined, the CIP counter is reset by the solver every time a large changeover occurs, but no CIP batch is scheduled. This option is not available for absolute-time CIP rules.
If you select this option, ensure that the corresponding option is selected on the Solver's CIP tab.

If you have specified the Absolute time rule type, this option is disabled.
If you want to use a gauge, select enable gauge. Specify the gauge's date and time, then the gauge value. To disable the gauge, enter a gauge date of "00-00-0000".
In this example, a resource's batch count rule specifies that a CIP batch must be placed after every 20 batches. At 9:00 A.M. the CIP batch scheduling for the day starts. At this moment in time, five batches that are not in the planning board have already been processed for this resource. In the planning board, the next CIP batch must be placed after the fifteenth process batch instead of the twentieth. To define these five batches as a start value, you can specify this information:
- The day's date as the gauge date
- 9:00 as the gauge time
- 5 as the gauge batch count
The CIP solver calculations start from 9:00 A.M. onward, using 5 as a start value.
Click OK to save the CIP rule.

Click the OK button to save your changes and close the window. Alternatively, continue populating tabs on this window.

If several CIP machines run on the same resource using different rules, you can create several CIP rules.

To delete a CIP rule, select a rule and click the Minus button at the top right of the tab.
