FRUIT COMPUTER COMPANY
Fruit Computer Company manufactures memory chips in batches of ten chips. From past experience, Fruit knows that 80% of all batches contain 10% (1 out of 10) defective chips, and 20% of all batches contain 50% (5 out of 10) defective chips. If a good (that is, 10% defective) batch of chips is sent to the next stage of production, processing costs of $4000 are incurred, and if a bad batch (50% defective) is sent on to the next stage of production, processing costs of $16000 are incurred. Fruit also has the alternative of reworking a batch at a cost of $4000. A reworked batch is sure to be a good batch. Alternatively, for a cost of $400, Fruit can test one chip from each batch in an attempt to determine whether the batch is defective.
QUESTIONS
1.Determine a strategy so Fruit can minimize the expected total cost per batch.
2.Compute the EVSI and EVPI.

CWD Electronics sells Televisions (TV), which it orders from the USA. Because of shipping and
handling costs, each order must be for 10 TVs. Because of the time it takes to receive an order, the
company places an order every time the present stock drops to 5 TVs. It costs $50 to place an
order. It costs the company $200 in lost sales when a customer asks for a TV and the warchouse
is out of stock. It costs $50 to keep each TV stored in the warehouse. If a customer cannot purchase
a TV when it is requested, the customer will not wait until one comes in but will go to a competitor.
The following probability distribution for demand for TV has been and the time required to
recæive an order once it is placed (lead time) has the following probability distribution:

- Zara stores in the United States stocks a particular type of designer denim jeans in the United States. It stores 500 pairs of jeans each month from its two suppliers. The Hong Kong supplier charges Zara $11 per pair of jeans, and the Colombian supplier charges $16 per pair (and then Zara marks them up almost 1,000%). Although the jeans from Hong Kong are less expensive, they also have more defects than those from Colombia. Based on past data, Zara estimates that 7% of the Hong Kong jeans will be defective compared to only 2% from Colombia and Zara does not want to import any more than 5% defective items. However, Zara does not want to rely on a single supplier, so it wants to order at least 20% from each supplier every month.a. Formulate a linear programming model for this problem. b.
