Simplex Method
Three types of paints are manufactured in one machine; Interior paint, Exterior paint and Paint for metal structures. The preparation time for each type of paint is 2, 3 and 4 minutes respectively and the processing time is 3, 2 and 1 minute. The profit contributed by each product is 12, 10 and 15 dollars respectively. The machine availability is 100 minutes and 200 minutes for machine setup.
1. Determine the optimum number of types of paints to be manufactured.
2. Determine the optimal utility value.
The company LED S.A DE C.V. produces 2 devices for lamps, devices 1 and 2 that require metal parts and electrical parts. The manager wants to determine how many units of each product should be manufactured to maximize the profit for each unit, device 1 requires 2 metal parts and 4 electrical parts, device 2 requires 4 metal parts and 2 electrical parts, the company has 24 units of each material available for batch production, device 1 generates $4 profit and device 2 generates $6 profit.
a) Formulate PL model.
b) Solve by the graphical method and determine what is the resulting maximum profit.
