Photon Technologies, Inc., a manufacturer of batteries for
mobile phones, signed a contract with a large electronics
manufacturer to produce three models of lithium-ion battery packs
for a new line of phones. The contract calls for the following:
Battery Pack |
Production Quantity |
PT-100 |
200,000 |
PT-200 |
100,000 |
PT-300 |
150,000 |
Photon Technologies can manufacture the battery packs at
manufacturing plants located in the Philippines and Mexico. The
unit cost of the battery packs differs at the two plants because of
differences in production equipment and wage rates. The unit costs
for each battery pack at each manufacturing plant are as
follows:
|
Plant |
Product |
Philippines |
Mexico |
PT-100 |
$0.95 |
$0.98 |
PT-200 |
$0.98 |
$1.06 |
PT-300 |
$1.34 |
$1.15 |
The PT-100 and PT-200 battery packs are produced using similar
production equipment available at both plants. However, each plant
has a limited capacity for the total number of PT-100 and PT-200
battery packs produced. The combined PT-100 and PT-200 production
capacities are 175,000 units at the Philippines plant and 160,000
units at the Mexico plant. The PT-300 production capacities are
75,000 units at the Philippines plant and 100,000 units at the
Mexico plant. The cost of shipping from the Philippines plant is
$0.18 per unit, and the cost of shipping from the Mexico plant is
$0.10 per unit.
(a) |
Develop a linear program that Photon Technologies can use to
determine how many units of each battery pack to produce at each
plant to minimize the total production and shipping cost associated
with the new contract. |
