Multi-plant Coordination • POK - Main Frame Assembly • KNG - Final Test and Ship • EFP - Supply CPU • ESS - Alternate CPU Supply • BUR - Supply Memory
Bill of Materials (BOM) • 308X Series Main Frame • Frame 1 - Power Supply and Cabling • Frame 2 - CPUs • Frame 3 - Memory and Math Functions • Frame 4 - Parallel CPU

How Much to Purchase? • Suppose we have an order for 10 Main Frames • 2 should have FR4 • 4 should have the special CPU • How many substrates are required?
How Many Substrates? • 10 Main Frames -> 10 Frame 2s -> 120 TCMs -> 120 Substrates • 2 MF w/FR4 -> 2 additional FR2s -> 24 TCMs -> 24 Substrates • 4 MF w/FR3 SP TCM -> 4 SP TCMs-> 4 Substrates • Total Substrates = 120+24+4=148

Determining Lead Times • If the Main Frame is made to order, what is the lead time? • Start from lowest level • At each level take the maximum parallel branch • Sum across the levels. • FR1 = 8, FR2 = 12, FR3 = 14, FR4 = 12 • Add 3 for Main Frame = 15 or 17 w/SP
Questions • What are the issues the manufacturing managers need to consider? • Focus on transportation, what issues seem important? • What parts would you need? • How much would you order and when? • Would you want to hold inventory? • At what point(s) would you want to hold it?
