The bullwhip effect refers to the increasing fluctuations in orders that often occur as orders move through the supply chain.

A restaurant runs a special promotion on lobster and plans to sell twice as many lobsters as usual. When this large order is sent to the distributor, the distributor assumes the large size is a trend, not a one-time event. The distributor therefore places an even larger order with the lobsterman. This behavior is the result of which of the following?

In traditional “wholesale price contracts”, the buyer specifies the precise quantity required and then to pay the supplier a cost per unit for the order.

Consider the following product structure. If the demand for product A is 50 units, how many units of component G will be needed?

We can always predict the future perfectly when we use forecasting methods.

The key difference between an EOQ inventory model where demand is known and one where demand is uncertain is in computing the reorder point.

Supply chain decisions are not generally strategic in nature, because purchasing is not a large expense for most firms.

Short-range forecasts tends to be more accurate than longer-range forecasts.

The first step in devising an effective supply chain strategy is to consider the nature of the demand for your products.

Suppose that the last five months of sales were 10, 8, 10, 6, 9 units, respectively. Suppose further that the last five forecasts were 11, 10, 8, 6, 8 units, respectively. What is the Mean Absolute Deviation (MAD) of these forecasts?
