Demand for your product averages 20 units per day, with a standard deviation of 4. Your lead time is 5 days. What should your reorder point be, if you want to have a 95% chance of not running out of products during the lead time? With this reorder level, how much safety stock do you have?

The chapter presented various approaches for the control of inventory investment. Discuss three additional approaches not included that might involve supply chain managers.
You are in charge of inventory control of a highly successful product retailed by your firm. Weekly demand for this item varies, with an average of 350 units and a standard deviation of 15 units. It is purchased from a wholesaler at a cost of $25.00 per unit. The supply lead time is 7 weeks. Placing an order costs $55.00, and the inventory carrying rate per year is 15 percent of the item's cost. Your firm operates 6 days per week, 50 weeks per year. Refer to the standard normal table The table below shows the total area under the normal curve for a point that is Z standard deviations to the right of the mean.

Demand for a product is relatively constant at 5 units per day. Lead time for this product is normally distributed with a mean of 20 days and a standard deviation of 4 days. (a) What reorder point provides an 80 percent service level? (b) What reorder point provides a 90 percent service level? (c) If the lead time standard deviation can be reduced from 4 days to 1, what reorder point now provides 90 percent service? How much is safety stock reduced by this change?
Demand during lead time for one brand of TV is normally distributed with a mean of 36 TVs and a standard deviation of 15 TVs. What safety stock should be carried for Dennis Yu's Appliance Outlet to provide a 90% service level? What is the appropriate reorder point? Use a Z standard deviation table as well What safety stock should be carried for a 90% service level? Safety stock =units (round your response to the nearest whole number). What is the appropriate reorder point? Reorder Point = units
You are in charge of inventory control of a highly successful product retailed by your firm. Weekly demand for this item varies, with an average of 200 units and a standard deviation of 16 units. It is purchased from a wholesaler at a cost of $12.50 per unit. You are using a continuous review system to control this inventory. The supply lead time is 4 weeks. Placingan order costs $50, and the inventory carrying rate per year is 20 percent of the item’s cost. Your firm operates 5 days per week, 50 weeks per year.a. What is the optimal ordering quantity for this item?b. How many units of the item should be maintained as safety stock for 99 percent protection against stockouts during an order cycle?c. If supply lead time can be reduced to 2 weeks, what is the percent reduction in the number of units maintained as safety stock for the same 99 percent stockout protection?d. If through appropriate sales promotions, the demand variability is reduced so that the standard deviation of weekly…
(a) AV City stocks and sells a particular brand of laptop. It costs the firm $625 each time it places an order with the manufacturer for the laptops. The cost of carrying one laptop in inventory for a year is $130. The store manager estimates that total annual demand for the laptops will be 1500 units, with a constant demand rate throughout the year. Orders are received within minutes after placement from a local warehouse maintained by the manufacturer. The store policy is never to have stock-outs of the laptops. The store is open for business every day of the year except Christmas Day. Determine the following: 1) Optimal order quantity per order2) Minimum total annual inventory costs3) The number of orders per year4) The time between orders (in working days) (b) Consider four cases of variation in the model parameters as follows: (a) Both ordering cost and carrying cost are 10% less than originally estimated; (b) both ordering cost and carrying cost are 10% higher than originally…
Annual demand for a product is 13,000 units; weekly demand is 250 units with a standard deviation of 40 units. The cost of placing an order is $100, and the time from ordering to receipt is four weeks. The annual inventory carrying cost is $0.65 per unit. To provide a 98 percent service probability, what must the reorder point be? Suppose the production manager is told to reduce the safety stock of this item by 100 units. If this is done, what will the new service probability be?
Daily demand for a certain product is normally distributed, with a mean of 100 and a standard deviation of 15. The supplier is reliable and maintains a constant lead time of 5 days. The cost of placing an order is $10 and the cost of holding inventory is $0.50 per unit per year. There are no stock-out costs, and unfilled orders are filled as soon as the order arrives. Assume sales occur over 360 days of the year. Your goal here is to find the order quantity and reorder point to satisfy a 90 percent probability of not stocking out during the lead time.a. What type of system is the company using?b. Find the order quantity.c. Find the reorder point.
The manager of an auto parts store is reviewing the inventory policy for one of their fastest selling products — car batteries. The store sells an average of 40 car batteries every week. The cost to hold one battery in inventory for a year is $15. The ordering cost per order is estimated at $50. The store operates all 52 weeks in a year.Use the information in Scenario 9.5. If the manager decides to order at the economic order quantity, what is the sum of the annual ordering cost and holding cost? Group of answer choices greater than $1800 but less than or equal to $2100
The concession stand at the Blacksburg High School stadium sells slices of pizza during soccergames. Concession stand sales are a primary source of revenue for high school athletic programs,so the athletic director wants to sell as much food as possible. However, any pizza notsold is given away to the players, coaches, and referees, or it is thrown away. The athletic directorwants to determine a reorder point that will meet, not exceed, the demand for pizza. Pizzasales are normally distributed, with a mean of 6 pizzas per hour and a standard deviation of2.5 pizzas. The pizzas are ordered from Pizza Town restaurant, and the mean delivery time is30 minutes, with a standard deviation of 8 minutes. Currently, the concession stand places an order when it has 1 pizza left. What level of service does this result in?
A 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?
I need a detailed explanation on how to solve this problem: A paint shop implements an inventory policy on its stock of white paint, which costs the store $6 per can. Monthly demand for cans of white paint is normal with mean 28 and standard deviation 8. The replenishment lead time is 14 weeks. Excess demand is backordered, but costs $10 per back ordered can in labor and loss of goodwill. There is a fixed cost of $15 per order, and the holding cost is based on 30% interest rate per annum. In your computations, assume 4 weeks per month. - Write down the model name and parameters. - What are the optimal lot size and reorder points for white paint (include the formulas)? - What is the optimal safety stock (include the formula)? *** Suppose the paint shop from the above problem adopts a service level policy. - What are the optimal lot size and reorder points for white paint, such that 90% of the cycles are filled without backordering (include all formulas)? - What is the fill rate…
