3) Amelia Ltd. 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. The company has orders for 48,000 of these trikes. Current schedules yield the following information. Requirements Cost to Cost to Component Plastic Time Space Manufacture Purchase Front 12 40 8 16 24 Seat/Frame 16 24 8 12 18 Rear wheel (each) .20 8 .4 2 6 Available 100000 320000 60000 The company obviously does not have the resources available to manufacture everything needed for the completion of 24000 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 24000 fully completed tricycles at the minimum cost.

PROBLEM-3) The Sales&Operations (S&OP) process is designed to produce a plan that all departmentswithin the organization, as well as suppliers to the organization, can work. The process is also sometimes referred toas sales, inventory, and operations planning (SIOP) to emphasize the important role that inventory can play as abuffer between sales planning and operations planning. The S&OP department of the XYZ company, that producesKLM products, estimates the sales over the next six years in thousands of packages will be as follows: Assume that each worker stays on the job for at least one year and XYZ currently has eight workers. XYZ estimatesthat they will have 600000 packages on hand at the end of the current year. Assume that, on average, eachworker is paid TL 60000 per year and is responsible for producing 80000 packages. Inventory costs have beenestimated to be 20 KRS per package per year, and shortages are not allowed. XYZ estimates that it costs TL 2500for each…
