Concept explainers
In a P system, the lead time for a box of weed-killer is 2 weeks and the review period is 1 week. Demand during the protection interval averages 218 boxes, with a standard deviation of 40 boxes.
- What is the cycle-service level when the target invent tory is set at 300 boxes?
- In the fall season, demand for weed-killer decreases but also becomes more highly variable. Assume that during the fall season, demand during the protection interval is expected to decrease to 180 boxes, but with a standard deviation of 50 boxes. What would be the cycle-service level if management keeps the target inventory level set at 300 boxes?

- Barbara Flynn is in charge of maintaining hospital supplies at General Hospital. During the past year, the mean lead time demand for bandage BX-5 was 60 (and was normally distributed). Furthermore, the standard deviation for BX-5 was 7. Ms. Flynn would like to maintain a 90% service level. Refer to the standard normal table for z-values. a) What safety stock level do you recommend for BX-5? Safety stock =units (round your response to the nearest whole number). b) What is the appropriate reorder point? Reorder Point =units (round your response to the nearest whole number).arrow_forwardYour company currently keeps a safety stock of 554 units of a particular product that has a lead time of 10 days.

Weekly demand for HP printers at a Sam's Club store is normally distributed, with a mean of250 and a standard deviation of 150. The store manager continuously monitors inventory andcurrently orders 1,000 printers each time the inventory drops to 600 printers. HP currentlytakes two weeks to fill an order. How much safety inventory does the store carry? What CSLdoes Sam's Club achieve as a result of this policy? What fill rate does the store achieve?Ex:. Return to the Sam's Club store in .

The company works 250 weeks a year; the lead-time on all orders placed is 6 working days. Assuming constant lead-time demand, and a unit cost of $45 what is the economic order quantity? What is the reorder point. If lead-time demand shows variability that follows a normal distribution with a mean μ =420 and a standard deviation σ =20, what will the revised reorder point if two stock-outs (shortages) are allowed? What is the company’s reorder point if the probability of a stock-out on any cycle is restricted to 0.05?arrow_forwardA retailer uses a periodic review order-up-to model to control the inventory of one of its high volume products. Average demand is 2580 units per week with a standard deviation of 1270. The review period is 5 weeks, the lead time is 11 weeks, and the safety factor used is 0.61. How many stockouts should the retailer expect for this product next year?arrow_forward

How many meat pies should the vendor make in order to ensure that he runs short on no more than 20% of days?arrow_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. d) If the weekly demand is 186 and there is a 1.5 week lead time - what is the reorder point (99% service level)? e) If the carrying cost per year is $0.50/unit/year - what is the additional cost associate with the 99% service level compared to 95% service level (i.e. cost of safety stock at 99% level - cost of safety stock at 95% service level)? solve on excelarrow_forwardPeter Sagan is in charge of maintaining hospital supplies at Champs Hospital.
