Project Week 1

Solution for Project 1 (Individual)
Answer the following questions using the enclosed computer output:
a) What is the optimal production schedule for this firm? What is the profit contribution of each of these products?
Answer: x1 = 0, x2 = 12, x3 = 21 profit = 1215
Contribution of x1 = 0, x2= 480, x3= 735
b) What is the marginal value of an additional hour of time on machine 1? Over what range of time is this marginal value valid?
Answer: 7.5 range 54–112.5
c) What is the opportunity cost associated with product 1? What interpretation should be given to this opportunity cost?
Answer: 12.5
For each unit produced of product 1, we would loose 12.5 from the profits.
d) How many hours are used for machine 3 with the optimal solution?
Answer: 78
d) How much can the contribution margin for product 2 change before the current optimal solution is no longer optimal?
Answer: (17.5–70)
Solution to Problem 1 of the Assignment:

Solution to Problem 2 of the assignment
Solution:
Let M be the number of units for milk
C be the number of units for chicken
B be the number of units for bread
V be the number of units for Vegetable
Objective Function:
Minimize Z= 0.42 M + 0.68 C + 0.32 B + 0.17 V
Constraints
160M + 210C + 120B + 150V = 300
90M + 190C + 90B + 130V >= 250
50M + 50C + 75B + 70V >= 60
210C / (160M + 210C + 120B + 150V) = 18
M, C, B, V >=
