The Deterministic Fuzzy Linear Approach in Planning the Production of Mine System with Several Open Pits
The paper deals with the problem of mining production planning by means of deterministic and fuzzy linear programming (LP). After the introduction, short inspection of the general settings in deterministic and fuzzy LP model is presented. An application and a comparative analysis of results obtained by both LP models was demonstrated on the example of the Mining Basin “Kolubara”, with four working open pit mines (OPM). Along with the assessment that the LP is an effi cient mathematical modelling tool in mining planning, and after comparing advantages and defi ciencies of the deterministic and fuzzy LP, the conclusion states that it is necessary to involve both of LP model approach in searching for the optimal production plan. The fi nal selection of solution lies with the decision maker.
