Problem 1.
Nana's Stuffin' is a popular food item during the fall and winter months, but it is marginal in the spring and summer. Use the following demand forecasts and costs to determine which of the following production planning strategies is best for Nana's Stuffin': (a ,b or c)
a. Level production over the 12 months.
b. Produce to meet demand each month. Absorb variations in demand by changing the size of the workforce.
c. Keep the workforce at its current level. Supplement with overtime and subcontracting as necessary.
d. Design a production plan for Nana's Stuffinusing linear programming and Excel Solver.

Problem 2
Sparrow Textile Mills produces two types of cotton cloth-denim and corduroy. Corduroy is a heavier grade of cotton cloth and, as such, requires 7.5 pounds of raw cotton per yard, whereas denim requires 5 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 510 yards per month. The manufacturer has 6500 pounds of cotton and 3000 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 of cloth to produce to maximize profit.
