A Vensim® model can be automatically calibrated to fit historical data series. You load the external data series and specify the parameters to adjust, then Vensim® automatically adjusts these parameters to get the best fit. Vensim’s optimizing engine searches through complex multi-dimensional surfaces looking for optimal solutions. You define the payoff (to maximize or minimize) then choose the policy parameters to adjust. An efficient Powell hill climbing algorithm searches for the best of policy parameters values to maximize the payoff. |

A Vensim® Applications or Venapp can be constructed to provide a management flight simulator interface for a model. Venapps allow individuals with little or no training in modeling to get meaningful access to a model. The Vensim® DLL is a separate program that can be called from other applications such as Visual Basic, Delphi, Excel and Multimedia Authoring Tools. Create your interface with these applications then call the DLL to access, simulate and analyze a Vensim model. Vensim® can also be set up as a Dynamic Data Exchange (DDE) server or client. |
