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.
