Chapter 13, Problem 22P
The injection molding department of a company uses an average of 30 gallons of special lubricant a day. The supply of the lubricant is replenished when the amount on hand is 170 gallons. It takes four days for an order to be delivered. Safety stock is 50 gallons, which provides a stockout risk of 9 percent. What amount of safety stock would provide a stockout risk of 3 percent? Assume normality.

A company begins a review of ordering policies for its continuous review system by checking the current policies for a sample of SKUS Following are the characteristics of one tem
Demand (D)=85 units/week (Assume 52 weeks per year)
Ordening and setup cost (S) $75/order
Holding cost (H)-$16/und/year
Lead time (L) 5 week(s)
Standard deviation of weekly demand 22 units
Cycle-service lovel-90 percent
>EOQ-207 units

The Westerville Auto Parts Company produces rocker-arm assemblies for use in the steering and suspen-sion systems of four-wheel-drive trucks. A typical container of parts spends 0.02 day in processing and0.08 day in materials handling and waiting during its manufacturing cycle. The daily demand for the part is2,000 units. Management believes that demand for the rocker-arm assembly is uncertain enough to war-rant a safety stock equivalent of 10 percent of its authorized inventory.a. If each container contains 22 parts, how many containers should be authorized?b. Suppose that a proposal to revise the plant layout would cut materials handling and waiting time percontainer to 0.06 day. How many containers would be needed?
