**(TCO 14)**Briefly discuss the decision methods used when there is complete uncertainty as to which state in a decision environment may occur. (Points : 10)**(TCOs 10,11 and 12)**Chad’s Pottery Barn has enough clay to make 24 small vases or 6 large vases. He has only enough of a special glazing compound to glaze 16 of the small vases or 8 of the large vases. Let X1 = the number of small vases and X2 = the number of large vases.- The smaller vases sell for $3 each, and the larger vases would bring $9 each.

**(TCO 1 &2)**What is the forecast for Aug based on a weighted moving average applied to the following past demand data and using the weights: 5, 3, 1.5? (largest weight is for most recent data)**(TCO 3, 4, and 5)**The XYZ Paint Shop owns and operates a dozen shops in southern Iowa. Their signature paint is black epoxy. Sales (X, in millions of dollars) is related to Profits (Y, in hundreds of thousands of dollars) by the regression equation Y = 6.321 + 0.65X. What is your forecast of profit for a store with sales of $25 million? $65 million? (Points : 30)**(TCO 6 and 7)**A product is currently made in a job shop, where fixed costs are $4,500 per year and variable cost is $10 per unit. The firm sells the product for $70 per unit. What is the break-even point for this operation? What is the profit (or loss) on a demand of 220 units per year? (Points : 30)**(TCO 13, 14)**XYZ coating company has reviewed four new processes for improving their coating line. The four processes, labeled A, B, C, and D use different technology and have different capacities. All the processes have the same level of production and the lifetime. The four states of nature represent four levels of consumer acceptance of the firm’s products. Values in the table are net present value of future profits in millions of dollars. Forecasts indicate that there is a 0.4 probability of acceptance level 1, 0.3 chance of acceptance level 2, 0.6 chance of acceptance level 3, and 0.5 change of acceptance level 4………..Using the criterion of expected monetary value, which production alternative should be chosen?
