This tab is part of the Equipment Data dialog (common to all equipment types). The dialog can be viewed when selecting the Equipment Data menu option from a unit procedure’s command menu. This tab presents information mostly for viewing purposes. The only editable entry on this tab is:
‘Omit from Throughput Analysis’: if checked, then this equipment resource and all of its contained procedures are excluded from any calculations for throughput analysis and evaluation.
The following quantities are presented on this tab. The table information is especially useful if the equipment resource is shared amongst more then one procedures.
|
The total time that the equipment is busy (active) over the recipe cycle time (or time between consecutive batch starts). Provides a good measure as to well (in time) this equipment resource is being utilized. |
|
|
Is Throughput Bottleneck (conservative PMT) |
Flag is checked if this equipment sets the Potential Maximum Throughput (PMT) using the conservative model of estimation. |
|
Is Throughput Bottleneck |
Flag is checked if this equipment sets the Potential Maximum Throughput (PMT) using the realistic model of estimation. |
|
Is Throughput Bottleneck (theoretical PMT) |
Flag is checked if this equipment sets the Potential Maximum Throughput (PMT) using the theoretical model of estimation. |
|
Maximum Fill (%) |
For a given procedure it presents the maximum (or most active) of all the operation steps working to vessel volume percentage. |
|
Capacity Utilization (%) |
For a given procedure it presents how much of the total equipment capacity is currently utilized by that procedure. Provides a measure as to how well the equipment resource’s capacity is being utilized by a procedure. |
|
Time Utilization (%) |
For a given procedure it presents the occupancy time as percentage of the recipe cycle time. See also Scheduling Terms & Definitions. |
|
Combined Utilization (%) |
For a given procedure, it is the product of its capacity utilization and the equipment’s uptime fraction. It presents an index that is a good measure as to how well in capacity and in time a given procedure employs this equipment resource. |
For more information on the above terms as well as how they are used in performing a complete throughput analysis of a given process, see Definitions & Theory of Throughput Analysis.
The above indices for all procedures are also presented in charts, see Throughput Analysis: Batch Size/Throughput Potential Chart and Throughput Analysis: Utilization Factors Chart.
