Direct auto transportation

Route: Donetsk –Rome

t_del.a= t_p.dep+ t_ride+ t_l.arr+ t_st ,

where t_del.a – delivery time, hours;

t_p.dep – primary operations, hours;

t_ride – time of delivery itself, hours;

t_l.arr – finite operations, hours;

t_st – stop for 15-17h per 1000 km, hours.

Consignment imported at intermediate warehouses, where formed Long Distance. In the final paragraph export cargo is carried by the recipient of intermediate composition.

In case :

t_p.dep = t_l + t_tr + t_tw + t_cus.a ,

where t_l – loading, hours;

t_tr – transshipment warehouse, hours;

t_tw – transport-warehouse operations, hours;

t_cus.a – customs operations, hours.

T_l.arr= t_tw+ t_cus.a + t_sh+ t_con ,

where t_tw – transport warehouse operations;

t_cus.a – customs operations;

t_sh – transportation in;

t_con – operations at destination, hours.

Duration of in/out transportation is calculated for the 1^st variant of air transportation.

Duration of main line transportation by truck:

Where K_п – coefficient of trucks supply to warehouses (1,02–1,04);

L_ам – distance of auto route, km;

V_м – average speed en-route , km/hours.
