The store purchases the necklaces at $2 each and sells them to customers for $4 each. Any necklaces left unsold after the Saint Patrick’s Day will be donated to a local community center. The store expects demand to be normally distributed with a mean of $70 and a variance of 25. In addition, the owner of the store suddenly found 40 green bead necklaces in their warehouse. These 40 necklaces were produced by ‘Bead Factory’ last year and are identical to the ones they’re about to order. Besides, all 40 are in brand new condition and the owner decide to sell them as well. How many necklaces should the store owner purchase from ‘Bead Factory’ ? If instead of 40 necklaces, they found 95 green bead necklaces in the warehouse, how many should the store owner order then? Problem 2. (S,s) policy. (30pts) The department store manager found that the daily demand for a chocolate gift basket follows normal distribution with mean 20 and standard deviation 2. The store checks its stock at the end of each week (one check every 7 days). And there is no lead time when the store orders the chocolate gift basket from their supplier. Suppose the store wants the type I service level to be 99%. If the store uses (s,S) policy and s=S, what is the minimum base stock level? (That is what the minimum value S should be to make the type I service level at least 99%.) Problem 3. (Q,R) model.(30pts) A gift store is selling a GT branded cap for $20 each. The store buys the GT caps from its supplier for $15 each and it costs $25 to place an order (fixed cost). It takes one month to deliver the order from the supplier and the holding cost for each cap is $0.25. When a customer arrives with demand for the cap, the penalty associated with not having a GT cap is $4 per cap. The monthly demand for the GT cap follows normal distribution with a mean 30 and standard deviation 8. According to the (Q,R) model, we try to find the optimal inventory policy based on approximation. The value of in iteration 0 is given. Please solve for , and in iteration 1.
