Unbalance terminal control method at the reception, storage and delivery of petroleum products to the fuel depots of JSC 'Russian Railways'

In many areas of the economy the problem of bringing a complex control object at a predetermined state corresponding to a preassigned certain requirements arises. To solve it, the terminal management method is used. A typical example of tasks of terminal control is to manage synchronization of the tank emptying with the petroleum product with simultaneous synchronous writing off of its mass recorded in the database during supply of oil products. The article addresses the control method of supply of petroleum products to the consumer that allows in the terminal time to save the initial value of unbalance between the actual mass of oil product in a reservoir, and the mass of oil product indicated in the accounting documentation. In practice, the method can be implemented with control algorithm of terminal control, provided that the relative error of the incoming of the actual mass of oil product to the tank is within the range stated in regulations. The article offers mathematical apparatus, based on results of probability theory and statistical decision theory, showing that the use of control method allows keeping the original supplier relative error for oil product when it is delivered to the consumer, not increasing it by the error of measuring instruments by tank and / or accounting site.
