Assume the demand for a companys drug Wozac during the current year is 50,000, and assume demand will grow at 5% a year. If the company builds a plant that can produce x units of Wozac per year, it will cost 16x. Each unit of Wozac is sold for 3. Each unit of Wozac produced incurs a variable production cost of 0.20. It costs 0.40 per year to operate a unit of capacity. Determine how large a Wozac plant the company should build to maximize its expected profit over the next 10 years.
A company is using a continuous review system for its inventory. Due to the contracts made with the customers, the weekly demand is constantly 40 units. The average lead time of orders is 2 weeks and the standard deviation of lead time is 1 week. The current service level is 95%. In order to reduce inventory holding costs, the company wants to reduce its reorder point. To achieve this, there are two options that have approximately the same cost for the company: reduce the standard deviation of lead time to 0.5 weeks or reduce the service level to 90%. A) Which option is more advantageous for the company? B) How much reduction does this option bring in the reorder point as opposed to the current situation? Show your calculations

The "Footcandy" shoes store supplies men's black formal shoes. Every 3 months the "Footcandy" shoes store can sell approximately 500 pairs of shoes at a constant price. The store is currently ordering 500 everytime they order. It costs $ 30 to place the order. 20% is the annual rate for the storage fee. With an order of 500 pairs of shoes, the store got the lowest price at $ 28 per pair. The order quantity discounts offered by the manufacturer are as follows Quantity Price 1 0-99 $36 2 100-199 $32 3 200-299 $30 4 300 $28 a. What is the minimum cost order amount for the shoes? b. What is the annual savings from Footcandy Store?
You were asked to assist with optimising the stock ordering and holding process for a company that sells car batteries. As part of the process, you need to decide the optimal order size to minimise associated costs. You are given the following information: • The batteries cost R400 each. • Sales volumes are constant at 600 batteries per month. • The lead time from order to delivery is 14 days. • It costs R360 for every order to be processed. It is calculated that it costs R5 to store a battery per month. 4) Calculate the optimal total costs.
Fixed-order-interval. This type of problem can be recognized when an order interval is given (e.g.,inventory is ordered every 10 days) along with the demand rate, lead time, and quantity on hand atorder time. Use Formula 13–16 to find the optimal order size.A lab orders a number of chemicals from the same supplier every 30 days. Lead time is five days.The assistant manager of the lab must determine how much of one of these chemicals to order. Acheck of stock revealed that eleven 25-milliliter (ml) jars are on hand. Daily usage of the chemical isapproximately normal with a mean of 15.2 ml per day and a standard deviation of 1.6 ml per day. Thedesired service level for this chemical is 95 percent.a. How many jars of the chemical should be ordered?b. What is the average amount of safety stock of the chemical?
A firm manages its inventory with an order-up-to model. Each period is one day, thelead time is two days, the order-up-to level is 10, and its inventory position at the start ofa day (before it submits an order for that day) is –4. Which of the following statementsis definitely true? a. Demand was four units yesterday.b. Demand was 10 units yesterday.c. There are at least four units backordered.d. There are 14 units on order before it orders today.e. After today’s order, there will be 14 units on order.f. It will receive more inventory today
