Dorothy lacks cash to pay for a $840.00 dishwasher. She could buy it from the store on credit by making 12 monthly payments of $71.52. The total cost would then be $858.24. Instead, Dorothy decides to deposit $70.00 a month in the bank until she has saved enough money to pay cash for the dishwasher. One year later, she has saved $882.00—$840.00 in deposits plus interest. When she goes back to the store, she finds the dishwasher now costs $886.20. Its price has gone up 5.50 percent.
Was postponing her purchase a good trade-off for Dorothy?

- Global Logistics needs to rent space for storing product for the next three years. The following information regarding the demand and spot price is available. Current demand for the product is 150,000. Historically, Global Logistics has required 1500 square feet to store 1500 units of the product. Demand for the product can go up by 20% with a probability of 0.7 or down by 20% with a probability of 0.3. Global Logistics can sign a three-year fixed lease to rent 150,000 square feet of space at $1.00 per square foot per year. The firm may also choose to obtain warehousing space on the spot market. The current spot market price is $1.20 per square foot per year. The spot price can go up by 10% with a probability of 0.8 and can decrease by 10% with a probability of 0.2.

- You work for the Brad's Nailer Company which manufactures two types of nailers: a pneumatic model and a cordless model. You have contracted to supply a national retail chain with both pneumatic nailers and cordless nailers. However, Brad's nailer production capability is limited in three departments: production, testing, and packaging. Your answer will be the revenue for a production plan that maximizes revenue - rounded to the nearest whole dollar. (The number of nailers may not be a whole number, which is acceptable in this chapter.) Use Scenario 2 Pneum. Revenue Pneum. Prod Hrs Pneum. Test Hrs Pneum. Pkg Hrs Pneum.

Once everythree months, a shipment of the cars is made to Happy Henry’s. Emergencyshipments can be made between these three-month intervals to resupply the carswhen inventory falls short of demand. The emergency shipments require twoweeks, and buyers are willing to wait this long for the cars, but will generally goelsewhere before the next three-month shipment is due.From experience, it appears that the demand for the EX123 over a three-monthinterval is normally distributed with a mean of 60 and a variance of 36. The cost ofholding an EX123 for one year is $500. Emergency shipments cost $250 per carover and above normal shipping costs.a. How many cars should Happy Henry’s be purchasing every three months?b.

The manufacturer sells a product to the retailer, who in turn sells in the market. Demand E is uncertain with cumulative distribution function F (·)and probability density function f (·). Since the production lead time is much longer thanthe selling season, the retailer must place a single order before demand is realized and cannotreplenish her inventory during the season. The retailer sells the product at an exogenousand fixed retail price r. The manufacturer produces the product at a unit cost of c. Themanufacturer uses a linear sales rebate contract and determines the following contract terms:For each unit ordered, he charges the retailer a wholesale price w, and for each unit sold, hepays the retailer a rebate s.
