could decrease future sales
Which of the following is NOT often associated with supplier-managed inventory (SMI) arrangements?
customers recommend to suppliers how they should schedule production

finished goods
Which of the following is not a demand planning requirement?
handle time fences

order the discounted EOQ amount

periodic review inventory system
In the end, the point of using the EOQ formula is to
point us toward the possible lowest cost option
which of the following is not a reason for increased importance of S&OP?
precise demands by key customers
In a situation where there are low economies of scale and a long response time, the supply chain strategy should focus on
production flexibility since detailed and accurate forecasting is not of critical importance

summing the daily average demand per day
which of the following is not a benefit of sales and operations planning?
the S&OP process eliminates the need to have finished goods inventory
Which of the following statements is true when comparing the total cost curve a product without discounting and the total cost curve with discounting?
the discounted curve is always below the undiscounted curve but does not really exist for values less than the minimum order amount to receive the discount
