USE OF METHODS OF DECISION THEORY FOR CHOOSING THE OPTIMAL STRATEGY FOR MEDICINES PURCHASES
The article considers the organization of optimal procurement of medicines for pharmacies with a decentralized management option. Simulation statistical models are presented for inventory management system with a fixed order size and fixed order frequency. Collection of the data that reflect pharmacy operation in terms of its financial indicators dynamics depending on various alternatives for organizing procurement and characterizing profits and costs of each strategy proposed is organized using simulation models. The simulation results are summarized in a utility matrix. Matrix rows correspond to the strategies possible, and columns correspond to financial indicators with criteria they should strive to identified per indicator. The methods of decision theory are applied to identify the best strategy with varying probabilities. The test results are shown, which demonstrated that almost all the methods applied pointed to the same strategy.
