Tots Toys makes a plastic tricycle that is composed of three major components: a handlebar-front wheel-pedal assembly, a seat and frame unit, and rear wheels. Please note that each tricycle requires two rear wheels, the front wheel is included in the front wheel-pedal assembly. The company has orders for 15,000 of these tricycles. Current schedules yield the following information:

Develop a linear programming model to tell the company how many of each component should be manufactured and how many should be purchased in order to provide 15,000 fully completed tricycles at the minimum cost.
Use Excel's Solver to obtain the optimal solution. How many of each component should be manufactured vs. purchased? What is the overall cost? What are the binding constraints?

The bill of materials (BOM) for product A is shown in the figure below. The lotsizing rule and other
information for each item can be found in the table. The demand for product A is 400 units in week 5,
600 units in week 6, and 500 units in week 7. Production lead time for product A is 1 weeks. Develop

The company obviously does not have the resources available to manufacture everything needed for the completion of 15,000 tricycles so has gathered purchase information for each component.
Develop a linear programming model to tell the company how many of each component should be manufactured and how many should be purchased in order to provide 15,000 fully completed tricycles at the minimum cost. (state the objective function, decision…
