IE 376 – Project Assignment Ford Motor Company Plastics Division JIT implementation
The Sandusky, Ohio, plastics plant Produces head, side and tail lamps, temperature switches and door latches for air cleaners Tail lamps –Lens, clips, studs, butyl, gaskets (purchased) –Body (produced)
Tail lamp production Molding Painting Assembly Packing Shipment
Molding department ton machines ($900000) ton machines 8 different types of molds ($100000) The types of molds required for each model, the types of the cavities and the cycle time in seconds are provided. Exhibit 4: Escort540 (2 available) 254 Thunderbird642 (left side only) 169
Molding department (contd) The press assignment for each mold type is provided. (for a day) Exhibit 5: m/c no.m/c typemolds assigned The setup times: –45 min, 1 hour 45 min, 4 hours Tail lamp production is 10% of the total workload of 21 machines (page 7)
Molding department (contd) The production plan for each mold type is provided. (for a week) Exhibit 6: moldweekly schedule (units) Mold cycle time for mold type 539 is 54/2=27 seconds/unit
Painting Two lines units per hour per line can be produced The setup time is 3-5 minutes Only one shift 8 workers
Assembly Two flexible assembly systems Two shifts Setup time minutes Standard production rates for each model are provided. Exhibit 8: Part namenet 8 hr standardcycles/hr Escort Rear (R&L)
Shipping Rails and trucks are used for shipments. One weeks daily shipping schedule for each model is provided in exhibit 9. The assembly plant locations are provided in exhibit 3. ModelMon.Tues.Wed.Thurs. Fri. Lynx Lynx is produced in Canada and New Jersey
Planning 4-week plans (20 production days) Weekly tail lamp production requirement schedule by month for each model is provided in exhibit 2. AIM: To operate under just-in-time philosophy.
What do we want from you? Evaluate the performance of the existing system under JIT philosophy. –What are the problems at each stage (from purchasing to shipping)? –How can you solve the problems mentioned above?
What do we want from you? (contd) We provide some questions, which will help you to analyze the system. Find some other key questions Answer the questions Support your ideas by using the information provided in the text. –Show calculations when necessary –You can make assumptions, but state them in your report Write an engineering report.
Example The problem: The capacity is not enough to satisfy the demand in department X. –Show that demand > capacity –How did you calculate the capacity? Solution method: Buy a new machine –Is the investment cost justified?
