Economic modelling under conditions of exploitation of cohesive construction minerals

Managers of mining companies use for decision-making on optimization of manufacturing processes advanced modelling methods and simulations on computers. The article proposes and analyses the model of a mining company production cycle consisting of a three-dimensional quarry model, technology model and economic-mathematical model. Based on the latter model an economic simulation model of a quarry has been created in the MS Excel program currently available on all personal computers, which measures outputs in the form of changes in total and unit costs according to the generic classification of costs in response to changes in inputs in the form of parameters of technology equipment and other operating parameters. Managers use the economic simulation model of quarry as decision support to increase profitability or improve competitiveness of their product from the sector of construction minerals.
