To solve a number of production, economic, organizational, logistics and operational management tasks, an information normative base of indicators is needed that is adequate for use in various periods of operation of existing rolling shops. Such periods include planning and actual operation of the workshop, reconstruction, modernization and improvement of new technologies. All these periods should be accompanied by an analysis and rapid restructuring of the information and regulatory framework, in which the primary task is to justify the productivity of the shop. At the same time, in many cases there is an insufficiently substantiated methodology for determining the productivity standards of rolling shops for a given assortment, which leads to inefficient use of equipment due to unforeseen downtime of metal at different stages of processing, increases cycle times, and reduces the productivity of rolling shops. The paper shows the significant role of productivity as an indicator of the efficiency of rolling shops and the relationship with technical and economic indicators. The main drawback of the applied calculation of the productivity of rolling shops with a sequential structure of sections is indicated, in each of which partial productivity is determined, and then the smallest value is selected from them. At the same time, difficulties arise in obtaining reliable data on metal consumption coefficients for sections. In this regard, the proposed model for substantiating the productivity of the workshop has a number of advantages: it corresponds to the clock approach and the possibility of using the total consumption coefficient of the metal from the available accounting information. The comprehensive research and analysis of the data obtained in the sheet-rolling shop made it possible to form an algorithm for the standard productivity of the shop based on a clock approach. Models of rational modes of reductions, rolling processes, technically possible cycles of work of roughing and finishing stands for a given assortment are given. Examples of the obtained values, based on the required dimensions of the finished sheets and the selected sections of the slabs, are shown fragmentarily in the tables.
