system dynamics information delay


Applies third order exponential delay to input value.


syInformationDelay3(InputValue, DelayTime, TimeNow)

The syInformationDelay3 function syntax has the following arguments:

  • InputValue: required. Input value that should get delayed.
  • DelayTime: required. Delay time.
  • TimeNow: required. Reference to a cell with syClock().

Return value is delayed input value.


The InputValue represents the value (as an information) arrived into the delay element during the last time interval.

The function applies third order exponential delay to the value on its way for the specified DelayTime.

Typical input to this element is syStock() value. Output can be used as DiscreteChange of syState().


  • =syInformationDelay3(A3,C3,A1) - Value arriving from cell A3 is exponentially delayed by the time that is set as a result of formula in cell C3.
