The constraints are being the capacity of containers in terms of volume. Due to custom regulation and labor scarcity the firm was forced to ship a specific number of boxes for each product. The maximum it can ship 800 for ECO STAR, 1250 for REFLEX and 2000 for CLEO. Other problems with the shipment were the capacity utilization which mandated the firm to ship the product 1 in 20’DFC only and the product 3 in 40’ DFC. Product 2 can be shipped in any of the container.
After complete evaluation of the process for shipment and the costs involved in it the firm has found that the profit per box for product are:
ECO STAR- $ 75/box
REFLEX- $60/box
CLEO- $85/box
