The StockPort_Special is typically used for a dynamic stock, e.g., a stock with some kind of internal behavior (e.g., a higher-order delay, a conveyor or an oven). While usually the rate of flow is determined by flow elements, here the real variable data is most often used to signal the value of flow to the flow element, as the rate of flow is determined by the stock - not the flow - in that case.
It has the following connectors:
| CONNECTOR | TYPE | DESCRIPTION |
|---|---|---|
| data | Real |
Rate of flow to be observed by connected flow element |
| rate (flow) | Real |
Flow that affects the stock |
StockPort_Sepcial connectors will only connect to FlowPort_Special connectors.
The StockPort_Special connector was used by Peter Junglas as MassPortR for his approach to SystemDynamics modeling [18, Chapter 12] (see here for a SystemDynamics Modelica library published by Peter Junglas) and has been simplified for the Business Simulation library.
