What technique does the text use to determine the best number of suppliers to manage disaster risk?

In a safety stock problem where both demand and lead time are variable, demand averages 200 units per day with a daily standard deviation of 25, and lead time averages 5 days with a standard deviation of 2 days. How much safety stock is required for a 90% service level?

When using the factor weighting approach, most companies will use the same list of criteria and the same criteria weights.

Which of the following would NOT generally be a motive for a firm to hold inventories?

Walsh Construction is considering two options for its supplier portfolio. Option 1 uses two local suppliers. Each has a "unique-event" risk of 8%, and the probability of a "super-event" that would disable both at the same time is estimated to be 2.5%. Option 2 uses two suppliers located in different countries. Each has a "unique-event" risk of 18%, and the probability of a "super-event" that would disable both at the same time is estimated to be 1.2%. (a) What is the probability that both suppliers will be disrupted using option 1? (b) What is the probability that both suppliers will be disrupted using option 2? (c) Which option would provide the lowest risk of a total shutdown?

Consider a local club selling Christmas trees. If trees cost $20 and sell for $70 with no salvage value, what is the ideal service level? If salvage value is increased to $5, what is the change in service level?

Which of the following statements about ABC analysis is FALSE?

Montegut Manufacturing produces a product for which the annual demand is 10,000 units. Production averages 80 units per day, while demand is 60 units per day. Holding costs are $5.00 per unit per year, and setup cost is $200.00. (a) If the firm wishes to produce this product in economic batches, what size batch should be used? (b) What is the maximum inventory level? (c) How many order cycles are there per year? (d) What are the total annual setup and holding costs?

A major challenge in inventory management is to maintain a balance between inventory investment and customer service.

A toy manufacturer makes its own wind-up motors, which are then put into its toys. While the toy manufacturing process is continuous, the motors are intermittent flow. Data on the manufacture of the motors appears below. Annual demand (D) = 25,000 units Daily subassembly production rate = 1,000 Setup cost (S) = $85 per batch Daily subassembly usage rate = 400 Carrying cost = $2.00 per unit per year (a) To minimize cost, how large should each batch of subassemblies be? (b) Approximately how many days are required to produce a batch? (c) How long is a complete cycle? (d) What is the average inventory for this problem? (e) What is the total annual inventory cost (holding plus setup) of the optimal behavior in this problem?

Inventory that separates various parts of the production process performs a(n) ________ function.
