- H & K Electronic Warehouse sells a 12-pack of AAA batteries, and this is a very popular item. Demand for this is normally distributed, with an average of 50 packs per day and a standard deviation of 16. The average delivery time is 5 days, with a standard deviation of 2 days. Delivery time has been found to be normally distributed. A 96% service level is desired. What is the standard deviation of demand during the lead time? How much safety stock should be carried, and what should be the reorder pointarrow_forwardIf the company in #8 uses exponential smoothing (smoothing factor = .6) and the forecast for the year is the figure they use for EOQ calculations, calculate the EOQ using the following information: The cost of ordering and carrying cost % are the same as #7 Cost of ordering: $25 Carrying costs: 45% Starting with 2018, Forecast the 2020 demand using exponential smoothing and then use that forecast as the annual demand. year sales 2017 1,000,000 2018 1,200,000 2019 2,000,000 2020arrow_forwardPeter Sagan is in charge of maintaining hospital supplies at Champs Hospital. During the past year the mean weekly demand for a special type of tubing was 186 packages of this tubing with a standard deviation of 13 packages of tubing. The lead time for receiving this tubing from the supplier is 1.5 weeks. Peter would like to maintain a 95% service level and places an order for 750 packages every time an order is placed. a) How much safety stock should be used for a 95% service level? b) If the weekly demand is 186 and there is a 1.5 week lead time - what is the reorder point (95% service level)? c) How much safety stock should be used for a 99% service level? solve using excelarrow_forward
