Assume that two years have passed, and the purchasing agent mentioned in Problem22 must recompute the optimal number of wafers to purchase and from whichsource to purchase them. Source B has decided to accept any size offer, but sells thewafers for $2.55 each for orders of up to 3,000 wafers and $2.25 each for the incremental amount ordered over 3,000 wafers. Source A still has the same price schedule, and Source C went out of business. Now which source should be used?
A purchasing agent for a particular type of silicon wafer used in the production ofsemiconductors must decide among three sources. Source A will sell the siliconwafers for $2.50 per wafer, independently of the number of wafers ordered. Source Bwill sell the wafers for $2.40 each but will not consider an order for fewer than3,000 wafers, and Source C will sell the wafers for $2.30 each but will not acceptan order for fewer than 4,000 wafers. Assume an order setup cost of $100 and anannual requirement of 20,000 wafers. Assume a 20 percent annual interest rate forholding cost calculations.c. If the replenishment lead time for wafers is three months, determine the reorderpoint based on the on-hand level of inventory of wafers

- Pricing Decisions at Madison The Madison Company manufactures and retails a certain product. The company wants to determine the price that maximizes its profit from this product. The unit cost of producing and marketing the product is 50. Madison will certainly charge at least 50 for the product to ensure that it makes some profit. However, there is a very competitive market for this product, so that Madisons demand falls sharply when it increases its price. How should the company proceed?2 In the pricing model in Example 7.1 with the constant elasticity demand function, the assumption is that all units demanded are sold. Suppose the company has the capacity to produce only 200 units. If demand is less than capacity, all of demand is sold. If demand is greater than or equal to capacity, only 200 units are sold. Use Solver to find the optimal price and the corresponding profit. Then use SolverTable to see how sensitive these answers are to the production capacity, letting it vary from 170 to 230 in increments of 10. Discuss your findings relative to the original solution in Example 7.1. In other words, what is the effect of capacity on the optimal price and profit?arrow_forwardA purchasing agent for a particular type of silicon wafer used in the production ofsemiconductors must decide among three sources.

Sarah hopes that customers are likely to purchase more if they see an increase in theinventory in the store.c. Sarah knows that even though she may triple her order quantity, this would increaseher operating costs by far less than a factor of three.d.

- After visiting several automobile dealerships, Richard selects the used car he wants. He likes its $12,900 price, but financing through the dealer is no bargain. He has $2,500 cash for a down payment, so he needs an $10,400 loan. In shopping at several banks for an installment loan, he learns that interest on most automobile loans is quoted at add-on rates. That is, during the life of the loan, interest is paid on the full amount borrowed even though a portion of the principal has been paid back. Richard borrows $10,400 for a period of four years at an add-on interest rate of 10 percent.

The unit cost of the handbag to the store is $28.50 andthe handbag will sell for $150.00. Any handbags not sold by the end of the seasonare purchased by a discount firm for $20.00. In addition, the store accountantsestimate that there is a cost of $0.40 for each dollar tied up in inventory, as thisdollar invested elsewhere could have yielded a gross profit. Assume that this costis attached to unsold bags only.a. Suppose that the sales of the bags are equally likely to be anywhere from 50to 250 handbags during the season. Based on this, how many bags should thebuyer purchase? (Hint: This means that the correct distribution of demand isuniform. You may solve this problem assuming either a discrete or a continuousuniform distribution.)b. A detailed analysis of past data shows that the number of bags sold is…arrow_forward
