1. There are no user-editable entries in this tab. All information is presented for viewing purposes alone.
2. The ‘Omit from Throughput Analysis’ check box is automatically set if the host equipment’s corresponding check is set or cleared from the Equipment Data Dialog: Throughput Tab. In other words, either all procedures hosted by an equipment resource are included in throughput analysis or none.
3. The Size/Throughput Utilization Fraction is the ratio between the maximum (design) value of the size indicative variable of the hosting equipment resource (e.g. volume for vessel types) and the maximum amount utilized by the operations in this unit procedure. For equipment resources whose capacity is measured with throughput values (e.g. labeling or printing) it is then the ratio between the rated value and the actual value as utilized by the most demanding operation in this procedure.
4. The Equipment Uptime Fraction is the ratio between the total time that the hosting equipment resource is active (‘on’) over the effective cycle time of the process (for batch processes - for continuous processes of course this ratio is always 100%).
5. The Combined Utilization Fraction is simply the product of the above two factors expressed as a percentage.
6. The final three indices shown in this dialog (Conservative PMT, Realistic PMT and Theoretical PMT) are the ratios between the actual equivalent product throughput through this procedure over the maximum achievable amount (Potential Maximum Throughput, or PMT) as calculated under three different scenarios (conservatively, realistically or theoretically). If this procedure happens to set the minimum value for an index, then the corresponding ‘Is Bottleneck’ box is shown as checked. More information on the how exactly these indices are calculated and their importance when evaluating a process for debottlenecking purposes is presented in Debottlenecking.
