Lookup

Partial lookup for causal loop diagramming

Diagram

Information

This information is part of the Business Simulation Library (BSL).

Partial class to be used for extensions within lookup classes.

The input can be given using a StockInfoInput connector (in which case the stock value will be used) or using the input u depending upon the structural parameter hasStockInfoInput.

The input will be normalized(→DmnlInput) using either the parameter referenceValue (default = 1) or the optional input u_ref.

Notes

The normalization will return zero if the reference value given (parameter or input connector) is zero.

pol	Value: "±" Type: String Description: Polarity
referenceValue	Value: 1 Type: ReferenceType Description: Constant reference value to normalize input
hasConstantReference	Value: true Type: Boolean Description: = true, if the reference value is given by a constant parameter
hasStockInfoInput	Value: true Type: Boolean Description: = true, if the input is given by the input connector u instead of stockInfoInput
