Using the actual sales (in units) over the past 15 months, a demand planner at a leading e-commerce firm has
forecasted the demand for a popular consumer product as shown below. Forecast 1 and Forecast 2 represent the
outputs of two comparative forecasting methods currently used by the sales and marketing, and operations
departments of the firm.

A manager of inventory systems believes that inventory models are important decision-
making tools. The manager often uses an Economic Order Quantity policy, but has never
considered a backorder model, because the company has always treated backorders as a
bad practice to be avoided. However, with upper management's continued pressure to cut
costs, you have been asked to analyze the economics of a backorder policy for some
products. A specific product has annual demand of 800 units, an order cost of $150/order,
an annual holding cost of $3/item, and a backorder cost of $20/item. Your task it to
determine the annual savings, when compared with an EOQ model, that backorders
would allow. Assume 250 working days per year.
Compare the primary types of forecasting methods used to determine demand.

- A manufacturer produces two models of television stands. The table at the left shows the times (in hours) required for assembling, staining, and packaging the two models. The total times available for assembling, staining, and packaging are 3750 hours, 8950 hours, and 2650 hours, respectively. The profits per unit are $30 for model I and $40 for model II. What is the optimal inventory level for each model? What is the optimal profit?arrow_forwardThe Lawson Fabric Mill Produces five different fabrics. Each fabric can be woven on one or more of the mill’s 36 looms. The sales department’s forecast of demand for the next month is shown in below Table 1, along with data on the selling price per yard, variable cost per yard, and purchase price per yard. The mill operates 24 hours a day and is scheduled for 30 days during the coming month. The mill has two types of looms: draw and regular. The draw looms are more versatile and can be used for all five fabrics. The regular looms can produce only three of the fabrics. The mill has a total of 36 looms: 8 are draw and 28 are regular. The rate of production for each fabric on each type of loom is given in below Table 2. The time required to change over from producing one fabric to another is negligible and does not have to be considered. The Lawson Fabric Mill satisfies all demand with either its own fabric or fabric purchased from another mill.

The following data show the total expenses (), the percentage of the total budget spent on administrative expenses, the percentage spent on fundraising expenses, and the percentage spent on program expenses for supersized charities.
