| Summary: | A promising direction of the efficiency in the functioning of complex production complexes is the construction and analysis of their normative models. To substantiate the normative output capacity of an electric furnace shop (EFS), normative clock models have been created for the operation of each equipment unit in EFS departments, namely, the preparation of charge materials, furnace, out-of-furnace processing, continuous casting of steel. The process of building a clock model is presented; it includes the following stages: the decomposition of an object (shop), the classification of production operations and elements, the selection of a method for determining the standard values of cycles, the establishment of a unit of account, the calculation of process cycles for each department, and the estimation of an object operation cycle. The structure of clock models for the functioning of the main (furnace) equipment, as well as auxiliary departments, is presented in detail. An algorithm for determining the EFS operation cycle has been formed. The comprehensive studies (monitoring of equipment operation, timing observations, statistical data processing) performed in EFSs and the cycles obtained by modeling revealed the existing “bottlenecks” (imbalances) that reduce the output capacity of the shop and suggested an upgrade option in the department of out-of-furnace steel processing. A comparative analysis of the normative values of the main technical and economic indices before and after the proposed reconstruction has been performed. This analysis would reduce the cycle of the furnace department and the hot downtime and would increase the output capacity, the actual fund of the shop’s working time, and the output; as a result, the cost of production will decrease and the profits and profitability from the sale of marketable products will increase Текстовый файл AM_Agreement |
