This question will have you calculating 2 different EOQ and ROP values and interpreting the results. For both EOQ and ROP, give your final answer in full sock sets (ROUND UP to the next whole number). The specific questions to answer are based in parts a-c. Tips to solve the EOQ and ROP are given below in bullet points. a) Calculate EOQ and ROP for FY2020 based on the FY2020 forecast value that you determined to be most accurate in Question #1. b) Calculate the EOQ and ROP based upon actual demand for FY2020 c) Use the total inventory cost calculation determine total inventory costs for each of the three EOQ results: EOQ from part a, EOQ from part b, and the Q that Throx is currently using (given in the case) When determining the costs use 2020 actuals for your Demand (D). i. Compare the total inventory costs from the three results and analyze what it shows you. ii. What are the implications of the ROP Throx is currently using versus the ROP based on Actual Demand. . 6 See additional tips below: Use a service level of 95% (z=1.65) when calculating the ROP For the standard deviation of weekly demand, use the data provided in the table on page 2 of the case with the FY2020 forecast for all approaches. Annual Inventory management costs will include the following: Annual Holding Costs, Annual Ordering Costs, and Purchase Cost.

Product Orders (Demand) Information

They provide you with the following information about forecasts for FY 2017 through FY2020: Weighted Moving Average uses Wt = 0.7 and Wt-1 =0.3 Exponential Smoothing uses = 0.8. Demand Characteristic 2019 2020 Annual Demand, sets 26,450 29,940 Average Weekly Demand 509 576 Std Dev of weekly Demand 127 144 Actual Demand (Three Sock Sets) Weighted Moving Average Fcst Exponential Forecast 2017 18,500 14,500 15,000 2018 22,875 17,750 17,800 2019 26,450 21,563 21,860 2020 29,940 25,378 25,532 3 Inventory Management Information The initial inventory for all sock styles combined at the beginning of FY 2021 is 2,250 units.
