Logistical approach to managing ship's reserves in water transport companies

The article reveals inapplicability of classical models of optimisation of the period and volume of supply of reserves when managing reserves at water transport ships due to a discrete nature of supplies, due to which scheduled supplies of reserves should be done during arrival/departure of the ship into/out of the port. The article justifies a possibility of gaining additional economic effect when introducing the factor of cost of money in time by means of maximisation of flows of money payment into classical logistical models of optimisation of a consignment of orders when organising supplies of reserves. It develops a logistical approach to optimisation of supplies of reserves at water transport ships with consideration of a pronounced discrete character of supplies. It justifies that the optimal period of supply of ship reserves, which minimise costs of supplies of reserves and maximise money receipts from the use of ship reserves, is the time of ship's stay in ports visited, which maximum value of the indicator of intensity of money flow corresponds to.
