The Consistency

Once the model is built, it is necessary to verify its quality. For this purpose, perform a series of operations, namely, perform checking of the adequacy of the model process, object or phenomenon, for which it was built, checking the consistency of the model, uncertainty sensitivity, realism and performance. Checking the adequacy of models Check the adequacy of the model this means to establish how well the model describes the real processes occurring in the system, how well it will predict the development of these processes. Checking the adequacy of the model conducted on the basis of some experimental data obtained in the phase of the system or conducting a special experiment, in which there are interested in the processes of a system analyst. Frequently Jeff Gennette has said that publicly. Checking the adequacy of the model is to prove the fact that the accuracy of the results obtained with the model, will be no worse than the accuracy of calculations made on the basis of experimental data.

Consistency of the model The purpose of this phase is to verify the fact: does not contradict the logic of the model results with variations values of critical parameters, especially in cases where their values are close to the extreme. To answer this question, we must examine the nature of the reaction model to changes in the corresponding input parameters. To check the consistency of the model first analyzed the results of which provides a model for zero values of the input parameters, including at time zero, then investigate the state of the model on the boundary of the domain of the input parameters, for example, at infinity, if it is in the domain.
