Suppose that in the given problem the space consumed by each vegetable is not proportional to its cost. In particular, suppose that one pound of lettuce required 0.4 square foot of space and one pound of zucchini required 1 square foot of space. Determine upper and lower bounds on the optimal values of the order quantities in this case. Test different values of the Lagrange multiplier to find the optimal values of the order quantities. (A spreadsheet is ideally suited for this kind of calculation. If you solve the problem using a spreadsheet, place the Lagrange multiplier in a cell so that its value can be changed easily.)
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?
Consider that you work at Kroger Grocery store, and that you've been tasked with creating an ABC inventory classification for 6 items. The 6 items, as well as their profit per case and number of cases sold per week, are as follows:Ribeye Steak - $135 in profit per case, 3 cases sold per weekLobster Tail - $245 in profit per case, 3 cases sold per weekPasta - $23 in profit per case, 12 cases sold per weekSalt - $3 in profit per case, 2 cases sold per weekNapkins - $12 in profit per case, 2 cases sold per weekTomato Sauce - $23 in profit per case, 11 cases sold per weekUsing total weekly profits, please classify each products into A, B, or C categories. Which items form the boundary of the class A and B items in your classification, and why? Which items form the boundary of the class B and C items in your classification, and why?

Costs included in the model are holding cost per unit, ordering cost, and the cost of goods ordered. The assumptions for that model are that only a single item is considered, that the entire quantity ordered arrives at one time, that the demand for the item is constant over time, and that no shortages are allowed. Suppose we relax the first assumption and allow for multiple items that are independent except for a restriction on the amount of space available to store the products. The following model describes this situation: Let Dj = annual demand for item j Cj = unit cost of item j Sj = cost per order placed for item j i = inventory carrying charge as a percentage of the cost per unit W = the maximum amount of space available for all goods wj = space required for item j The decision variables are Qj , the amount of item j to order.

Use the economic order quantity formula (EOQ = SQRT((2SD/H)) to determine the optimal number of units that the company should order based on each assumed level of order based on each assumed level of order quantities provided in the data. b. Complete the table by calculating the number of orders per year, annual order cost, annual holding cost, and annual total cost. Highlight the minimum annual total cost using conditional formatting. Hint: The minimum cost should equal the cost at the EOQ you calculated in part a. c. Create a line chart that graphs annual order cost, annual holding cost, and annual total cost. The x-axis should be the quantity ordered. Include a chart legend, appropriate chart title, axes labels, and properly formatted amounts on the axes. d. Examine the chart and your responses to parts a and b. Indicate any relationships.arrow_forward

- c. Once you find the optimal order quantity i.e., EOQ, create a Data Table that generates inventory cost within ±100 units (with 10units increment) from the optimal order quantity. For example, if the EOQ=150, then you need to generate Data Table for inventory cost starting from 50 to 250 with 10 increments. Explain the exact steps completed in excel to create the data table d. Create a Scatter plot with “smooth lines” for the Data Table created in c) to show the inventory cost. Label your plot clearly (axis and title). The optimum order quantity should indicate the minimum cost in your plot.arrow_forwardThe maintenance department of a large hospital uses about 816 cases of liquid cleanserannually.

Using the economic order quantity approach, the optimal production run would be 200 when the cost of carrying one jacket in inventory for one year is 0.40. The given solution is this: 200 = 2*setup cost* Annual Demand / Carrying cost200 = 2*2*4000/ Carrying cost40000 = 16000 / Carrying costCarrying cost = 16000 / 40000Carrying Cost = 0.4 Hence, the cost of carrying one jacket in inventory for one year is 0.4 QUESTION: How did you get the 40,000 (that was divided to 16,000)?arrow_forward
