The choice of type of model of industrial system is considered. It is shown that from the point of view systemotology all existing models share on imitating (portrait) and optimizing, and the problem of designing of industrial systems belongs to the class poorly structuring of problems. Hence, at a macrodesigning stage use not imitating, but optimizing models is expedient. The expanded definition of technological process, as sets of designing of a product, designing of technological process of sequence of form-building products, manufacturing is resulted. Definition of flexibility of manufacture and adaptation of industrial system to changes of conditions is made.
