Typical use cases of the crop simulation models consist of such operations as parametric identification, yield forecast and optimization, analysis of different technologies etc. All these tasks relate to multiple running of the model with several variants of input parameters and can be automated by means of polyvariant crop simulation framework which allows performing the multiple running in the batch mode. Such framework has been developed in our laboratory. It makes it possible to register any crop simulation model in the database and to perform several typical operations with it. As a result we present the wide-functional computer system for planning and automation of multi-factor computer experiment with arbitrary dynamic crop models.
