Lookup

Partial lookup for causal loop diagramming

Diagram

Information

This information is part of the Business Simulation Library (BSL). Please support this work and ► donate.

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.

Parameters (4)

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

Connectors (4)

	stockInfoInput	Type: StockInfoInput Description: Input of record with stock-related information
