Learning Objectives
After today’s lecture, and after working the homework problems, the student should be solve handle balanced and unbalanced transportation problems.
Topics covered in today’s class
Balanced transportation/haul problem:
Given the following information:
Jobsite Requirements (truckloads/month): A needs 30, B needs 40, C needs 20. (Total = 90)
Plant Production (truckloads/month): E can supply 50, F can supply 40. (Total = 90)
Thus the needs exactly balance the supply.
Shipping Costs:
To Jobsite A 
To Jobsite B 
To Jobsite C 

From Plant E 
$5/truckload 
$50/truckload 
$60ruckload 
From Plant F 
$10/truckload 
$80/truckload 
$90/truckload 
Required: Determine the minimum shipping costs for supplying each jobsite.
Unbalanced transportation/haul problem – excess supply:
Given the following information:
Jobsite Requirements (truckloads/month): A needs 30, B needs 40, C needs 20. (Total = 90)
Plant Production (truckloads/month): E can supply 60, F can supply 40. (Total = 100)
Shipping Costs:
To Jobsite A 
To Jobsite B 
To Jobsite C 

From Plant E 
$5/truckload 
$50/truckload 
$60ruckload 
From Plant F 
$10/truckload 
$80/truckload 
$90/truckload 
Required: Determine the minimum shipping costs for supplying each jobsite.
Unbalanced transportation/haul problem – supply shortage:
Given the following information:
Jobsite Requirements (truckloads/month): A needs 30, B needs 40, C needs 20. (Total = 90)
Plant Production (truckloads/month): E can supply 30, F can supply 40. (Total = 70)
Shipping Costs:
To Jobsite A 
To Jobsite B 
To Jobsite C 

From Plant E 
$5/truckload 
$50/truckload 
$60ruckload 
From Plant F 
$10/truckload 
$80/truckload 
$90/truckload 
Required: Determine the minimum shipping costs for supplying each jobsite.
