Sam's Pet Hotel operates 51 weeks per year, 6 days per week, and uses a continuous review inventory system. It purchases kitty litter for $11.00 per bag.
The following information is available about these bags:
> Demand
95 bags/week
> Order cost $52.00/order
> Annual holding cost = 25 percent of cost
> Desired cycle-service level = 80 percent
>Lead time 4 weeks (24 working days)
> Standard deviation of weekly demand = 15 bags
> Current on-hand inventory is 320 bags, with no open orders or backorders.
a. Suppose that the weekly demand forecast of 95 bags is incorrect and actual demand averages only 75 bags per week. How much higher will total
costs be, owing to the distorted EOQ caused by this forecast error?
The costs will be $
higher owing to the error in EOQ. (Enter your response rounded to two decimal places.)

C Consider the following m... As discussed in Section 8.3, the Markowitz model uses the variance of the portfolio as the measure of risk. However, variance includes deviations both below and above the mean return. Semivariance includes only deviations below the mean and is considered by many to be a better measure of risk. (a) Develop a model that minimizes semivariance for the Hauck Financial data given in the file HauckData with a required return of 10%. Assume that the five planning scenarios in the Hauck Financial Services model are equally likely to occur. Hint: Modify model (8.10)-(8.19).

- The Harvey Motorcycle Company produces three models: the Tiger, a sure-footed dirt bike; the LX2000, a nimble cafe racer; and the Golden, a large interstate tourer. The month's master production schedule calls for the production of 32 Goldens, 31 LX2000s, and 38 Tigers per 10-hour shift. What average cycle time is required for the assembly line to achieve the production quota in 10 hours? 0.099 hours per motorcycle. (Enter your response rounded to three decimal places.) If mixed-model scheduling is used, how many of each model will be produced before the production cycle is repeated? The greatest common divisor of the production requirements is Therefore, the Harvey Motorcycle Company will produce Goldens, LX2000s, and Tigers.

The beginning times for the shifts are 8:00 a.m., noon, 4:00 p.m., 8:00 p.m., midnight, and 4:00 a.m. An officer beginning a shift at one of these times works for the next 8 hours. During normal weekday operations, the number of officers needed varies depending on the time of day.
