A shoe company forecasts the following demands during the next six months: month 1 – 200; month 2 – 260; month 3 – 240; month 4 – 340; month 5 – 190; month 6 – 150. It costs $7 to produce a pair of shoes with regular-time labor and $11 with overtime labor. During each month, regular production is limited to 200 pairs of shoes, and overtime production is limited to 100 pairs. It costs $1 per month to hold a pair of shoes in inventory. The initial inventory is 0. Let xi = pairs of shoes produced in month i using regular-time labor, yi = pairs of shoes produced in month i using overtime labor, and zi = inventory of shoes at the end of month i. Using these decision variables, formulate an LP that minimizes the total cost and meets the demand on time in the next six months.

During the next three months, Shoemakers, Inc. must meet(on time) the following demands for shoes: month 1, 1,000pairs; month 2, 1,500 pairs; month 3, 1,800 pairs. It takes 1hour of labor to produce a pair of shoes. During each of thenext three months, the following number of regular-time laborhours are available: month 1, 1,000 hours; month 2, 1,200hours; month 3, 1,200 hours. Each month, the company canrequire workers to put in up to 400 hours of overtime. Workersare paid only for the hours they work, and a worker receives$4 per hour for regular-time work and $6 per hour for overtimework. At the end of each month, a holding cost of $1.50 perpair of shoes is incurred. Formulate an MCNFP that can beused to minimize the total cost incurred in meeting thedemands of the next three months. A formulation requiresdrawing the appropriate network and determining the cij’s, bi’s,and arc capacities.

The Scottsville Textile Mill produces several different fabrics on eight dobby looms that operate 24 hours per day and are scheduled for 30 days in the coming month. The mill will produce only Fabric 1 and Fabric 2 during the coming month. Each dobby loom can turn out 4.63 yards of either fabric per hour. Assume that there is a monthly demand of 16,000 yards of Fabric 1 and 12,000 yards of Fabric 2. Profits are calculated as 33¢ per yard for each fabric produced on the dobby looms. Will it be possible to satisfy total demand? (a)Yes, the mill can produce enough to meet the demand. (b)No, the mill can not produce enough to meet the demand. In the event that total demand is not satisfied, the Scottsville Textile Mill will need to purchase the fabrics from another mill to make up the shortfall. Its profits on resold fabrics ordered from another mill amount to 20¢ per yard for Fabric 1 and 16¢ per yard for Fabric 2. How many yards of each fabric should it produce to maximize profits?…
A supermarket expects to sell 16,000 boxes of sugar in a year. Each box costs $2, and there is a fixed delivery charge of $20 per order. If it costs $1 to store a box for a year, what is the order size and how many times a year should the orders be placed to minimize inventory costs?
The Lechería La Vaquita company currently has three-star products, but it faces a problem of capacity to satisfy the demand for these products. In total, it has 65,000 machine hours per month for the production of these three products. The production time to produce a batch of 1000 liters each product, as well as its monthly demands are shown in the following table: * TABLE * Because in recent months there have been advertising campaigns for Leche Choco-Chavo and Leche Chavo Light, the company wants the demands for these products to be the first to be satisfied with the same level of importance, while Leche Chavo as it is a product already well positioned, it is the third priority of these products. Formulate the goal programming mathematical model for this problem by clearly defining the sets, constraint variables, parameters, objective function (s), and constraints.
A shoe company forecasts the following demands during the next six months: month 1—200; month 2—260; month 3—240; month 4—340; month 5—190; month 6—150. It costs $7 to produce a pair of shoes with regular-time labor (RT) and $11 with overtime labor (OT). During each month, regular production is limited to 200 pairs of shoes, and overtime production is limited to 100 pairs. It costs $1 per month to hold a pair of shoes in inventory. a) Formulate a balanced transportation problem by stating the rules. b) Minimize the total cost of meeting the next six months of demand on time by using different methods available and compare the results.
