The report contains a substantive and formal statement of the problem of parametric and structural adaptation of models used in the space-calendar planning of existing and prospective industrial enterprises. The need for this adaptation of models is caused by the objectively existing structural dynamics of these enterprises due to the impact of various classes of internal and external disturbances. In this case, by adapting the models, the quality and sustainability of the developed production plans is improved. The constructiveness of the developed approach is illustrated by the example of adapting the models of volume-calendar planning of the production activity of a shipbuilding enterprise.
