Question: Worley Fluid Supplies produces three types of
Worley Fluid Supplies produces three types of fluid-handling equipment: control valves, metering pumps, and hydraulic cylinders. All three products require assembly and testing before they can be shipped to customers.
A total of 3,150 minutes of assembly time and 2,100 minutes of testing time are available next week.
a. Develop a linear optimization model to determine how many pieces of equipment the company should make next week to maximize profit contribution.
b. Implement your model on a spreadsheet and find an optimal solution.
c. Explain the sensitivity information for the objective coefficients. What happens if the profit on hydraulic cylinders is decreased by $10?
d. Due to scheduled maintenance, the assembly time is expected to be only 3,000 minutes. How will this affect the solution?
e. A worker in the testing department has to take a personal leave because of a death in the family and will miss 3 days (24 hours). How will this affect the optimal solution?
