3. (30 points) Consider the BOM tree of a sub-assembly, namely A. Lead time (LT) consists of estimates for setup time, processing time, materials handling time between operations or waiting time, depending on the item type. Items (B,C,D,E,F,G) belong to one of the followings, raw materials, purchased parts or manufactured parts. LT is given in terms of weeks. Suppose that there is no on hand inventory and no scheduled receipts for all items. How many units of items E, D, and must be ordered produced and when to order/start production for these items to assemble X units of sub-assembly A? (let X be the sum of the mambers in your student ID anber). Assume all months are composed of 4 weeks. Assume, the current time is the beginning of 1' week of May. For further production processes, subassembly A must be ready at the beginning of 1 week of May. Therefore, its assembly must be started at the beginning of 4 week in Apnl, due to 1 week of lead time. Assume that only one order can be given for D, so be careful with its timing Note: Drawing a weekly timeline might be very useful to demonstrate the release and receipt times of order production Fill in the tables below. Show your work. Magic numbers are not accepted. Student ID Value of X How many to order or produce? When to give order or start production? (Beginning of which week of which month?) 3.
