Concept explainers
A
Interpretation: 18 days daily average ending inventory ending and stock out occurred is to be calculated.
Concept Introduction: Simulation is reflection of working of a process or system, Average daily ending inventory refers to mean value of ending day of the stock and stock out is mean by out of situation where representing returned order due to insufficient inventory.
B
Interpretation: Average inventory and stock out having simulation while Q=30, R=20 and making comparison with subpart (a) is to be determined.
Concept Introduction: Average inventory is the mean value of inventory in between certain periods and stock out is out of situation where representing returned order due to insufficient inventory.

Operations Management: Processes And Supply Chains (12th Global Edition) - Does Not Include Mylab Operations Management
- The chapter presented various approaches for the control of inventory investment. Discuss three additional approaches not included that might involve supply chain managers.arrow_forwardA pharmacist is trying to determine the inventory order and stock levels for a particular drug. The following information is available about the drug. Demand (D) 85 tablets/week Working weeks per year 52 weeks Unit holding cost per year (H) $6 Order cost (S) $44/order Standard deviation of weekly demand (sd) 15 tablets Lead time (L) 2 weeks Desired cycle service level 95% If the pharmacist uses the continuous review (Q) system to control the inventory of the drug, what would be the order quantity and reorder point? If the pharmacist uses the periodic review (P) system to control the inventory of the drug, what would be the review interval and target inventory level? (Hint: Use the EOQ model to derive the review interval P)arrow_forwardUniversity Drug Pharmaceuticals orders its antibiotics every two weeks (14 days) when a salesperson visits from one of the pharmaceutical companies. Tetracycline is one of its most prescribed antibiotics, with average daily demand of 2,000 capsules. The standard deviation of daily demand was derived from examining prescriptions filled over the past three months and was found to be 800 capsules. It takes five days for the order to arrive. University Drug would like to satisfy 99 percent of the prescriptions. The salesperson just arrived, and there are currently 25,000 capsules in stock. How many capsules should be ordered?arrow_forward
- Sam's Pet Hotel operates 52 weeks per year, 6 days per week, and uses a continuous review inventory system. It purchases kitty litter for $13.00 per bag. The following information is available about these bags: ≻Demand=75 bags/week ≻Order cost=$55.00/order ≻Annual holding cost=25 percent of cost ≻Desired cycle-service level=80 percent ≻Lead time=4 weeks (24 working days) ≻Standard deviation of weekly demand=15 bags ≻Current on-hand inventory is 320 bags, with no open orders or backorders. Part 2 a. Suppose that the weekly demand forecast of 75 bags is incorrect and actual demand averages only 50 bags per week. How much higher will total costs be, owing to the distorted EOQ caused by this forecast error? The costs will be $enter your response here higher owing to the error in EOQ. (Enter your response rounded to two decimal places.) a. What is the EOQ? What would the average time between orders (in weeks)? b. What should R be? c.

The cost of carrying the alcohol in inventory is P0.50 per gallon per year, and the cost of ordering is P150 per order. The firm uses the alcohol at a constant rate throughout the year. It takes 18 days to receive an order once it is placed. The reorder point is?arrow_forwardAs the Manager of Branson’s Department Store, you are responsible for ensuring that reorder quantities for the various items have been correctly established. You decide to test one item and choose product Z. A continuous review inventory policy has been used, so you examine this as well as other records and come up with the following data: Cost per unit $35 Holding cost 20 percent of unit cost Average daily demand 10 units Ordering cost $30 per order Standard deviation of daily demand 3 units Delivery lead time 4 days Because customers generally do not wait but go elsewhere, you decide on a service probability of 90 percent. Assume that Branson’s Department Store operates 320 days per year. [What is the annual demand (D)? Determine the optimal order quantity, Q*. Determine the reorder point (R) if demand is constant. Determine the reorder point (R) if demand is varies.arrow_forward
- The Big Buy Supermarket stocks Munchies Cereal. Demand for Munchies is 4,000 boxes peryear (365 days). It costs the store $60 per order of Munchies, and it costs $0.80 per box per yearto keep the cereal in stock. Once an order for Munchies is placed, it takes 4 days to receive theorder from a food distributor.

The following information is available about these bags: > Demand = 95 bags/week > Order cost = $50.00/order > Annual holding cost = 20 percent of cost > Desired cycle-service level = 80 percent > Lead time =5 weeks (30 working days) > Standard deviation of weekly demand = 15 bags > Current on-hand inventory is 320 bags, with no open orders or backorders. a. Suppose that the weekly demand forecast of 95 bags is incorrect and actual demand averages only 75 bags per week. How much higher will total costs be, owing to the distorted EOQ caused by this forecast error? The costs will be $ higher owing to the error in EOQ.

An American distributor stops by every four weeks to take orders. Because the orders are shipped directly from Italy, they take three weeks to arrive. Charlie's Pizza uses an average of 250 pounds of pepperoni each week, with a standard deviation of 50 pounds. Charlie's prides itself on offering only the best-quality ingredients and a high level of service, so it wants to ensure a 90% probability of not stocking out on pepperoni. Assume that the sales representative just walked in the door and there are currently 450 pounds of pepperoni in the walk-in cooler. How many pounds of pepperoni would you order?arrow_forward
