Abstract:
The article considers the example of coordinated and effective functioning of the parties

involved in the process related to road transport services in the logistics system of the regional agro
cluster – “regional warehouses of the agro cluster, road transport, customers". As an illustration, one of
the options for delivering products to the customer according to the agreed schedule and the list of
works to be performed are presented; Using graph theory, a network graph is drawn up, which allows
to determine the entire cycle of work, which is necessary for drawing up an agreed schedule for the
delivery of products to consumers in a regional agro cluster and working with a “just-in-time” system.
To determine the quantity of products to be delivered, the scientific direction Inventory Management
is used. An example of determining the optimal route for shipping products is given, where it is
determined which option should be chosen; the problem set to verify the correctness of the choice is
solved by a mathematical method, where the problem of drawing up a rational route with the
minimization formula is applied to the problem of linear programming.

In supply management,  Wilson's formula is  introduced to determine the optimal order size -
(OOS). Various works have been analyzed, where optimal order size report methods and application
practices are discussed. The formation of costs for storage of products and the amount of costs incurred
for  storage  are  discussed,  which include:  a)  constant  costs  for  storage  and maintenance  of  a  unit  of
products in stock in a specified period and the amount of constant costs for storage and maintenance
of a unit of products in the same period; b) variable costs of the unit of production in the period under
review, which are related to the current costs of inventory services (control, accounting, etc.).
 As an example, options for using warehouse space are discussed, in the form of flexible inventory
management and “fixed” stock management.

Consideration of transport costs when calculating the OOS, optimization of costs for the
performance of logistics functions, and the function of providing customers with products defined in
the agro cluster correspond to the modern approach to the effective operation of the logistics system
of the regional agro cluster.

Keywords: regional agro cluster; delivery of products; optimal route of delivery; optimal order size;
inventor storage costs.
