Study Guide for Chapter 5: 1. What does the acronym CPFR represent? a. | Coordinated planning and forecasting relationships | b. | Collaborative planning, forecasting, and replenishment | c. | Centralized purchasing and forecasting relationships | d. | Collaborative purchasing, forecasting, and receivables | 2. Some measures of forecasting accuracy include mean absolute deviation, mean absolute percentage error, and mean squared error. The formula for each is dependent on the forecast error, which is calculated by using the equation: a. | Actual demand for period t divided by the forecasted demand for period t | b. | Actual demand for period t plus the forecasted demand for period t | c. | Actual demand for period t minus the forecasted demand for period t | d. | The average of Actual demand for period t and forecasted demand for period t |
