(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.
