(a) Give examples of independent and related dependent demand (b) APL company assembles and sales an electronics device (ED) on a contract basis. End item ED has composed of 3 units of subassembly BG and 5 units of component DD. BG is assembled using 3 DDs and 4 FCs. There are orders of 500 and 875 units of the device (ED) at the beginning of week 6 and week 8. In assembling BG, an extra 20 percent scrap allowance must be added. DD can only be ordered in whole cases of 400 units per case. One case of DD is received in each of week 1 and week 2. Also, there are 200 units of BG and 425 units of DD now on hand. The lead time for the item BG, DD, and FC is 2 weeks and that is for the item ED is 1 week.i. Calculate the required number of DD and FC for producing 100 units of ED. There is no stock of any item. ii. Prepare a material requirements plan for the component DD.

- Problem 16-12 (Algo) Your company assembles five different models of a motor scooter that is sold in specialty stores in the United States. The company uses the same engine for all five models. You have been given the assignment of choosing a supplier for these engines for the coming year. Due to the size of your warehouse and other administrative restrictions, you must order the engines In lot sizes of 700 units. Because of the unique characteristics of the engine, special tooling is needed during the manufacturing process for which you agree to reimburse the supplier. Your assistant has obtained quotes from two reliable engine suppliers and you need to decide which to use.
