Irwin Textile Mills produces two types of cotton cloth - denim and corduroy. Corduroy is a heavier grade of cotton cloth that requires 8 pounds of raw cotton per yard, whereas denim requires 6 pounds of raw cotton per yard. A yard of corduroy requires 3.2 hours of processing time; a yard of denim requires 3.0 hours. Although the demand for denim is practically unlimited, the maximum demand for corduroy is 600 yards per month. The manufacturer has 6,500 pounds of cotton and 3,000 hours of processing time available each month. The manufacturer makes a profit of $2.25 per yard of denim and $3.10 per yard of corduroy. The manufacturer wants to know how many yards of each type cloth to produce to maximize profit. a) Formulate the linear programming model for this problem. b) Solve this model using the graphical approach. 2. The following payoff matrix indicates the profits associated with three decision options and four states of nature. State of Nature Option S1 S2 S3 S4 20 25 30 35 T1 40 30 40 20 T2 10 60 30 25 T3 Select the decision option according to 1) the maximin rule; 2) the maximax rule; 3) the Laplace rule (Equally likely) 4) the Hurwicz rule with = 0.2; and 5) the minimax regret rule. 3. Using exponential smoothing with a weight of 0.7 on actual values: a) If sales are $760,000, $820,000, $950,000 for 1993, 1994 and 1995, what would you forecast for 1996? b) Given this forecast and actual 1996 sales of $1,030,000, what would you then forecast for 1997? c) What sales would you forecast for 1997 using the simple regression (least squares) method?
