just need question (c) onwards ! Thanks
SECTION A 1 Zamsung Lid manicure Fishdrives for Notebook computers in a plant in Tuns. One of the Flash drive DXRE 1TB is shipped to Zenovo tablet computer manufacturers (the only custom his model) directly from Finished Goods inventory. Figure shows the manaw of Flash drives E40E upplies RE-ITH Tasche TO Eigure 1 Flow of XRIE Zamsung Flash drive to the Zenovo The performance of Zamsung XRIE ITB Flash drive Manufacturing system has been poor in terms of missed delivery of products with back orders, excess work in process, (WIP) and high level of finished goods inventory (a) List and briefly explain four (4) possible recommendations of lean manufacturing concepts as applicable to Zamsung manufacturing system to reduce the manufacturing lead time (currently 6 days) and to improve the overall throughput and cycle time performance of the Zamsung manufacturing. You may also include concepts of the theory of constraints in your recommendations (Keep your answers concise and focused as marks will not be given to irrelevant statements) (4 marks) Note: Question No. I continues on page 2. ATTENTON The Score Core MA4863 (b) For each of your above recommendation in question (a) briefly describe the can application, and its potential benefit to the manufacturing system. (Keep your answers concise and focused as marks will not be given to inrelevant statements). (4 marks) (c) Inventory level of Flash drive Finished Goods (FG) at Zamsung is reviewed at an interval of once per week (week-7 days). Immediately after each review, a quantity is ordered by the Zamsung Inventory controller to raise the total of in-hand and on order inventory of Flash drives in FG to be 434 units fie. Base-stock is 434). When Inventory controller places an order to the Zamsung plant, it delivers the requested quantity of XRIE Flash drive units to the FG after 6 days. Assume the daily demand for XRIE Flash drive is stable and normally distributed with a mean of 3 units and standard deviation is 4.5. Assume both the Zamsung plant and the Zenovo plant work 24 hours per day, 7 days per week throughout the year. (Normal distribution tables can be found in appendix 1 of this paper Compute the service level in terms of the coverage probability Type I service level) provided to Zenovo using the inventory control policy described above (4 marks) Compute the average number of stock out the FG investory per year, assuming $2 weeks of operation per year (4 mi) a (b) For each of your above recommendation in question (a), briefly describe application, and its potential benefit to the manufacturing system. (Keep your an concise and focused as marks will not be given to irrelevant statements) (4 marks) (c) Inventory level of Flash drive Finished Goods (FG) at Zamsung is reviewed at an interval of once per week (week-7 days). Immediately after each review, a quantity is ordered by the Zamsung Inventory controller to raise the total of in-hand and on- order inventory of Flash drives in FG to be 434 units (1.0. Base-stock is 434). When Inventory controller places an order to the Zamsung plant, it delivers the requested quantity of XRiE Flash drive units to the FG after 6 days. Assume the daily demand for XRIE Flash drive is stable and normally distributed with a mean of 31 units and standard deviation is 4.5. Assume both the Zamsung plant and the Zenovo plant work 24 hours per day, 7 days per week throughout the year. (Normal distribution tables can be found in appendix 1 of this paper) () Compute the service level in terms of the coverage probability (Type 1 service level) provided to Zenovo using the inventory control policy described above. (4 marks) Compute the average number of stock-outs at the FG inventory per year, assuming 52 weeks of operation per year (4 marks) (ii) Compute the average inventory level of the XRIE Flash drive units in FG inventory under this policy (1 mark) (iv) Zamsung decided to continuously review the thrilory of XRIE Flash drive units in the FG and use continuous review Q Entory policy with Economic Order Quantity (EOQ) as the Q value. As the daily demand and standard deviation of demand remain as specified in the cition and both the Zamsung and the Zenovo work 24 hours per day, 7 days per week throughout the year. The order cost (including transport) is $20 per order placed and holding per year is $45.26 per unit. What will be their order quantity based on the revised Q-R policy? (1 mark) (v) Zamsung manufacturing wanted to provide a coverage probability (Type 1 service level) of 99.5% for XRIE Flash Drives. At what level of inventory in FG should they place a new order in each cycle to provide such customer service? (4 marks) (vi) Given that approximate order cycle in days is determined by Q (units)/ (Mu) (units/day), how many stock-outs might they expect per year under this revised policy? (4 marks) Note: Question I continues on page 3 (vii) What will be the average inventory level of XRIE Zamsung Flash Drives at FG inventory with this revised inventory control system? (2 marks) (viii) If the XRiE Flash drive is a high-end product, which policy would you recommend and why? Use your computed measures in the earlier sections of each policy to justify your answer.
