APPLICATION OF THE TIMING MODEL IN REENGINEERING OF THE PRODUCTION SYSTEMS IN METALLURGY

The problem of creation of the timing model for difficult production systems and their application in reengineering of ferrous metallurgical enterprises are considered. The classification of timing models was carried out by their appointment, scale of the research object, degree of continuity of a material stream, quantity of simultaneously processed semi-products, number of production operations, importance of the equipment, statistical characteristics of a time step, extent of mechanization and automation of the equipment, by an entrance and an exit of a material stream. The leading role of the indicator “productivity” and its connection with other technical and economic indicators of a production system was shown. The factorial model of system capacity is given and the fundamental factor, namely a time step of system, is allocated. The basic formula for the estimation of productivity was offered on the basis of a time step. The technique of identification of “bottlenecks” of a production system on the basis of a timing approach and an assessment of actions efficiency of reengineering is shown. The example of the application of timing models for the analysis of “bottlenecks” in rolling production is given. Possibility of timing models application is noted for planning, forecasting and operational management of production.
