Let X and Y be the quantity of Product I and Product II respectively.
The objective is to maximize the profit. Hence the objective function Z, is given as below
Z = 1.5X+2Y
As total production cannot exceed 1200, we have the below constraint
X+Y1200
As demand for product II cannot be more than half of demand for product I, we have the below constraint
Y0.5X
-0.5X+Y0
As production level of product I is less than or equal to three time that of product II plus 600 we have the below constraint
X 3Y+600
X-3Y 600
For non negativity, we also have the constraint that X,Y 0
To find the solution, we can find plot the above constraint on the graph and the find the feasible solution area. We then find the value of the objective function at the corner points of the feasible solution. The point where the objective function has the maximum value is the solution.
The graph of the equation and the feasible area is shown in the below image
We can see that there are 4 corner points of the feasible solution.
A (0,0), B(800,400) C(1050,150) D(600,0)
We find the value of objective function 1.5X+2Y at each of the corner points
At A, the value is 1.5*0+2*0 = 0
At B, the value is 1.5*800+2*400 = 2000
At C, the value is 1.5*1050+2*150 =1875
At A, the value is 1.5*600+2*0 = 900
We can see that the maximum value occurs are B(800,400). Hence 800 Product I and 400 Product II need to be produced to maximize the profit.
The maximum profit is the value of objective function which is $2000

A manufacturer wants to maximize the profit of two products. Product X yields a profit of $ 2.50 per unit, and product Y yields a profit of $3.20 per unit. Market tests and available resources have indicated the following constraints: The combined production level should not exceed 1200 units per month. The demand for product Y is no more than half the demand for product X. The production level of product X is less than or equal to 600 units...

A chemical manufacturer produces three different chemical products. The profit per unit, the labor and raw material required per unit, and the pollution emitted per unit are given in the file. This company’s two objectives are to maximize profit and minimize pollution produced. The company wants to identify a set of points that constitute a trade-off curve for these two objectives. Formulate and solve an appropriate optimization model in the given shell file to help the chemical manufacturer find this...
LP Large Problem (4 marks for question, 6 marks for worksheet) A company sells three products: A, B, and C. The company has customer orders for 2,000 units of A, 3.750 B's, and 1,700 C's. The company makes the products in-house, which requires production and shipping resources (constraints 1, 2) as shown in the table below. The company can outsource some demand for A and B, but cannot outsource C. Outsourcing requires no production or shipping resources. The company wants...
Zapit, Inc. manufactures two products, Product A and Product B. Product A yields an incremental profit of $2 per unit, and Product B yields an incremental profit of $4. Product A requires four hours of processing at Machine A and two hours at Machine B. Product B requires six hours at Machine A, six hours at Machine B, and one hour at Machine C. Machine A has a maximum of 120 hours of available capacity per day, Machine B has...
A product, sold seasonly, yields a net profit of $100 for each unit sold and a net loss of $60 for each unit left unsold. The number of units for the product ordered at a department store during a season is the random variable X with probability density function P(X = i) = 1/il if 10 i 20 and P(X = i) = 1/10 otherwise. If the store must stock this product in advance, how many should it stores to...
Hint: The simplest way to complete assignment is to use an existing model....determine if the number of elements is larger/smaller (smaller would be to delete columns/rows...arer would be to insert columns/rows... then update formula's using the same logic as the original model.

Three units of raw material and 1.5 labor hours are needed to manufacturer one unit of product 1. Six units of raw material and 2 labor hours are need to manufacture one unit of product 2. The unit variable cost for product 1 is $20, and for product 2 is $20....
A "product mix" problem can be solved quite easily by hand, as long as there is only one constraint (i.e. one resource in which demand > capacity). However, when there are multiple constraints it becomes quite complex. In the lab, we used Solver to find the product mix that results in the highest profit, subject to capacity constraints for each resource, and the constraint that we would not make more than the demand for any given product. Set up a...
