1. What is the purpose of Shipment Node performance metrics?Shipment Node performance metrics measure both operational and planning performance. They report current shipment flows, evaluate shipment plan execution, calculate completion ratios, and provide historical statistics for long-term logistics analysis.
2. How is shipment plan completion calculated?The Shipment Node compares the actual shipped volume with the current shipment plan and calculates the corresponding completion ratio. Additional metrics report the remaining shipment volume and the current plan completion status.
3. Does Shipment Node support overplanning?Yes. Shipment Node can be configured to allow overplanning, enabling the actual shipped volume to exceed the planned shipment target when refinery operating conditions require additional product dispatch.
4. Are shipment plans carried over to the next planning period?No. Each planning period is evaluated independently. Unfulfilled shipment volumes are not automatically transferred to the next shipment plan, reflecting common refinery planning and pipeline dispatch practices.
5. How often are historical shipment statistics recorded?Historical records are stored automatically immediately before the shipment plan is updated. Therefore, the recording frequency depends on the selected planning strategy, typically once per month for
monthly planning or once per day for
daily scheduling.
6. Can historical shipment data be queried for a specific period?Yes. The historical database supports queries for individual
calendar months as well as arbitrary date ranges, allowing engineers to compare planned and actual shipment volumes over any reporting period.
7. Can Shipment Node statistics be integrated into refinery dashboards?Yes. All performance metrics are available through the Petroleum Refining Library API, making them suitable for Digital Twin dashboards, KPI reporting, production monitoring, and refinery logistics analytics.
8. What is the difference between flow statistics and shipment plan statistics?Flow statistics describe the current operating conditions of the Shipment Node, such as incoming flow rates. Shipment plan statistics evaluate operational performance by comparing planned and actual shipped volumes, calculating completion ratios, and tracking remaining shipment requirements.
9. How can Shipment Node statistics improve refinery production planning?Shipment Node statistics provide operational KPIs, shipment completion ratios, historical performance records, and logistics indicators that help engineers optimize refinery production planning, pipeline transportation, and Digital Twin decision support.
