TELBOY(TELEPHONY BOYACÁ)
TELBOY producing for high-end mobile Smartphone, including the display and batteries which are assembled to the phone body. 3 floors, the first is where the glass and ITO for mobile occurs, where the second and third stack which is assembled is manufactured.
Product 1: Display glass and ITO.Product 2: Battery for Smartphone.
The product 1 of the required capacity in the plants 1 and 3; 2 needs the product of the work of levels 2 and 3.
Determine what production rates should have two products in order to maximize total profits, subject to the restrictions imposed by limited production capacity available in the 3 levels.
Facts:● Number of production hours
available per week in each plant to manufacture the products.
● Hours of manufacture are used to produce each batch (50 units) of each new article in each of the plants.
● Earnings per batch of each new product.
Formulation as a linear programming problem
X1 = number 1 batch of product is manufactured by week.X2 = Product Lot Number 2 being manufactured per week.Z = total weekly earnings generated by these products.

SIMPLEX DUAL
If the value of the number of hours of production batches of the product number 1 which is manufactured by week 9-11 changed the gain is increased.
