Reality Check technology allows you to test simulation models against your understanding of reality. Constructing a model that accurately reflects a complex system can be very difficult. Reality Check provide an easy way of automatically checking statement about reality against behavior generated in a model, keeping the model in line with the real world. |

Sensitivity testing involves changing your assumptions about the value of inputs to model while performing multiple simulations, then examining the uncertainty in selected output variables. Vensim’s Monte Carlo Simulations, also known as Multivariate Sensitivity Simulations, automate sensitivity testing . Output can be displayed as graphs with confidence bounds, individual simulation traces, or histograms. Latin Hypercube sampling is also supported for faster sensitivity testing. |

Vensim® features a powerful subscripting language for constructing very advanced arrayed models. A simple model structure can be disaggregated to show detail complexity. Each subscripted structure can be individually customized with different constants, multiple equations, subscript functions ( such as summing over elements of a subscript), and up to eight dimensions of subscripts. Multiple sub ranges make it easy to construct and analyze subsets of an array. |
