Shipments formation on routes variants

Calculation of the duration and cost of cargo delivery

Direct air transportation through regional airport:

Route: Donetsk – Rome

1) regular transportation:

t_del.r= t_sh+ t_in + t_or + t_fl+ t_des + t_out + t_con ,

where t_del.r –time for transportation on regular routes, hours (days);

t_sh and t_con –time for cargo servicing at shippers and consignee sides ,hours;

t_in and t_out– time for transportation in/out, hours;

t_or and t_des – operations in origin/destination, hours;

t_fl – flight time, hours :

where and –distance for transportation in/out of airport, km;

and – speed of a truck in/out en-route, km/hours.

t_d= t_l.d+ t_c.d+ t_cus.d ,

where t_l.d – loading procedures in departure airport, hours;

t_c.d – commercial procedures in departure airport, hours;

t_cus.d – customs procedures in departure airport, hours.

t_arr= t_l.arr+ t_c.arr+ t_cus.arr,

where t_l.arr – loading procedures in arrival airport, hours;

t_c.arr – commercial procedures in arrival airport, hours;

t_cus.arr – customs procedures in arrival airport, hours.

Calculation results are presented in table 4.

Calculation:

hours , hours

1. Mass of cargo consignment - 90 kg:

t_or =0,42+0,67+1,5=2,59 hours

t_des =0,33+0,58+1,5=2,41 hours

t_del =0,25+0,86+2,59+2,07+2,41+0,44+0,17=8,79 hours (0,37 day)

2. Mass of cargo consignment- 200 kg:

t_or =0,5+0,75+1,58=2,83 hours

t_des =0,42+0,58+1,58=2,58 hours

t_del =0,33+0,86+2,3+2,07+2,58+0,44+0,25=9,36 hours (0,39 day)

3. Mass of cargo consignment- 500 kg:

t_or =0,58+0,83+1,67=3,08 hours

t_des =0,42+0,67+1,67=2,76 hours

t_del =0,42+0,86+3,08+2,07+2,76+0,44+0,33=9,96hours (0,42 day)

4. Mass of cargo consignment- 1500 kg:

t_or =0,75+1,17+1,83=3,75 hours

t_des =0,58+0,83+1,83=3,24 hours

t_del =0,5+0,86+3,75+2,07+3,24+0,44+0,42=11,28hours (0,47 day)

5. Mass of cargo consignment- 2500 kg:

t_or =0,92+1,5+2=4,42 hours

t_des =0,75+1++2=3,75 hours

t_del =0,58+0,86+4,42+2,07+3,75+0,44+0,5=12,62 hours (0,53 day)

6. Mass of cargo consignment- 3500 kg:

t_or =1,17+1,83+2,17=5,17 hours

t_des =1+1,33+2,17=4,5 hours

t_del =0,67+0,86+5,17+2,07+4,5+0,44+0,58=14,29 hours (0,6 day)
