SIMULATION OF HOMOGENEOUS PRODUCTION PROCESSES

Abstract

This paper is focused on streamlining the activity of the homogeneous production processes which form the production logistics of a particular extraction operation. The efficient extraction of millions of tonnes of raw materials presents a requirement for the correct use of the means of transport, machinery and equipment involved in the extraction of raw materials, with an economic, social, technical and ecological impact. The extraction operation studied is performed in a quarry for the extraction of limestone, which is used as input material for the production of various types of building materials. The extracted raw material gradually passes through the chain of extraction – loading – transport – unloading – crushing to the actual processing in the building materials plant. The results of the solution show that the maximum effective use of the operation of the defined system can be achieved with 27 means of transport and 4 loaders, while the utilization of workplaces in extraction operation workplaces is close to 100 % during the defined time of operation.
