UDC 621.138 © A.N. Feofanov, V.G. Mitrofanov, A.V. Kapitanov CHOICE OF TYPE OF MODEL OF INDUSTRIAL SYSTEMS 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. <...> Wide use of models of systems is basic feature of the system analysis [1]. <...> The system analysis has appeared as decision means poorly structuring problems, as methodology of a substantiation of the decision in the conditions of the essential uncertainty, uniting the general scheme of the system approach with analytical decision-making process. <...> The first approach consists in model approach to system at the expense of approach of number of coordinates of model to number of "phase" coordinates of system. <...> Creation of f lexible technological industrial systems is based on application of the manufacturing centers (MC), multiopurpul machine tools, flexible indust r ial modules (FIM), equipped with means of automation of loading of preparation and / or the tool, transportation and warehousing of preparations, details; automation of change of the tool and equipment, perfect control systems and the organization of the flexible manufacturing system (FMS). <...> Pressure of social factor (deficiency and dearness of skilled work) and the factor of preservation of the environment (recycling of a waste etc.) amplifies. <...> According to an estimation the next 30-60 years the further growth of automation of manufacture that is the basic means of satisfaction of the requirements set forth above is predicted. <...> If to speak about modeling of manufacturing systems (MS) degree of adequacy of model goes down, and abstraction level raises as with growth of degree of uncertainty of conditions, and design stage MS. The more adequately to diff icult system its model, the above its predictive and that below its explanatory qualities. <...> On the basis of more rough (simple) optimizing models only so-called "top" estimations of system effectiveness, but other exit in a situation can <...>
