Problem Statement: When I set up the VPOOL structure for the streams (for example LN1, LN5, HN2, HN5) the model is only using the LN streams in the blending and not using the HN streams. Shouldn’t VPOOL force the model to use all the streams in a fixed ratio? | Solution: For the VPOOL structure, PIMS gets to optimize the ratios of the components in the pool, so it doesn't necessarily have to use all the streams if it can remove some from ALL VPOOL dispositions. It just has to be consistent about the ratios EVERYWHERE that is not an exception to the VPOOL. To force usage of a ... |
Problem Statement: When splitting or copying a pipeline crude receipt, the Shipment ID begins with B instead or PLI. Is this supposed to happen? | Solution: When the events are split then the Shipment Id will begin with letter B as the event type is not checked at the time of splitting the event. The right prefix is given only when creating the new event.
For further information on the Shipment IDs for different events, please refer to the KB article below:

Problem Statement: What is the recommendation when setting up a rundown component in the model? | Solution: When you are setting up a Rundown Component in the model, it is recommended to set it along with a splitter that splits the rundown into a stream that goes into the blend and another that goes to a tank. If you do not set it up like this, then the component has to be used continuously, and if there are time g... |
Problem Statement: Does the model setting “Fix Quality of Zero Flow Pools to Initial Values” have any effect on the properties in XBOUNDS table? | Solution: PIMS uses the dynamic bounding to implement this quality fixing, so having hard bounds in XBOUNDS, means that PIMS can’t move them. So, having hard bounds in XBOUNDS means that the available initial value it is fixed to for zero flow pools will have to be within those hard bounds.
