a. If carrying costs are $2 per year for each stone, find the order quantity that will minimize total annual cost. (Round your intermediate calculations to the nearest whole number.)

Order quantity stones

b. If annual carrying costs are 23 percent of unit cost, what is the optimal order size? (Round your intermediate calculations to the nearest whole number.)

c. If lead time is 4 working days, at what point should the company reorder? (Round your intermediate calculations to the nearest whole number.)

Problem 13-15

A manufacturer of exercise equipment purchases the pulley section of the equipment from a supplier who lists these prices: less than 1,000, $5 each; 1,000 to 3,999, $4.95 each; 4,000 to 5,999, $4.90 each; and 6,000 or more, $4.85 each. Ordering costs are $49, annual carrying costs per unit are 40 percent of purchase cost, and annual usage is 4,860 pulleys.

Determine an order quantity that will minimize total cost. (Round "Q" values to the nearest whole number and all other calculations to 2 decimal places.)

Problem 13-16

A company will begin stocking remote control devices. Expected monthly demand is 820 units. The controllers can be purchased from either supplier A or supplier B. Their price lists are as follows:

SUPPLIER A SUPPLIER B

Quantity Unit Price Quantity Unit Price

1–199 $14.00 1–149 $14.10

200–499 13.80 150–349 13.90

500 + 15.2 350 + 13.70

________________________________________

Ordering cost is $47 and annual holding cost is 32 percent of unit price per unit.

Problem 13-19

Given this information:

Expected demand during lead time = 310 units

Standard deviation of lead time demand = 30 units

Use Table.

Determine each of the following, assuming that lead time demand is distributed normally:

a. The ROP that will provide a risk of stockout of 1 percent during lead time. (Round your answer to the nearest whole number.)

ROP units

b. The safety stock needed to attain a 1 percent risk of stockout during lead time. (Do not round intermediate calculations. Round your answer to the nearest whole number.)

Safety stock units

c-1. Would a stockout risk of 2 percent require more or less safety stock than a 1 percent risk?

Less

More

c-2. Would the ROP be larger, smaller, or unaffected if the acceptable risk were 2 percent instead of 1 percent?

Problem 13-20

Given this information:

Lead-time demand = 620 pounds

Standard deviation of lead time demand = 70 pounds (Assume normality.)

Acceptable stockout risk during lead time = 4 percent

Use Table.

a. What amount of safety stock is appropriate? (Round your answer to the nearest whole number.)

Safety stock units

b. When should this item be reordered? (Round your answer to the nearest whole number.)

ROP units

c. What risk of stockout would result from a decision not to have any safety stock? (Omit the "%" sign in your response.)
