(a)

Summary Introduction

Interpretation: Data needs to be plotted and analyzed about the time series.

Concept Introduction: The moving average method takes the average of the recent number of observations in any time series. The average is taken based on the k number of previous observations.

(b)

Summary Introduction

Interpretation: The forecast for November, using a two period moving averages needs to be calculated.

Concept Introduction: The moving average method takes the average of the recent number of observations in any time series. The average is taken based on the k number of previous observations.

(c)

Summary Introduction

Interpretation: The forecast for November, using a three period moving averages needs to be calculated.

Concept Introduction: The moving average method takes the average of the recent number of observations in any time series. The average is taken based on the k number of previous observations.

(d)

Summary Introduction

Interpretation: Mean Square error needs to be calculated for two and three period using moving average model

Concept Introduction: The moving average method takes the average of the recent number of observations in any time series. The average is taken based on the k number of previous observations.

(e)

Summary Introduction

Interpretation: The best number of periods for the moving average model needs to be determined based on MSE.

Concept Introduction: The moving average method takes the average of the recent number of observations in any time series. The average is taken based on the k number of previous observations.

What would an MA(1) forecasting method mean? Compare the accuracy of MA(1)and MA(4) forecasts for July through December 2013.
Consider the following time series data. Choose the correct time series plot. What type of pattern exists in the data? Develop a three-week moving average for this time series. Compute MSE and a forecast for week 7. Round your answers to two decimal places.  = 0.2 to compute the exponential smoothing values for the time series. Compute MSE and a forecast for week 7. Round your answers to two decimal places. Compare the three-week moving average forecast with the exponential smoothing forecast using  Use trial and error to find a value of the exponential smoothing coefficient  that results in a smaller MSE than what you calculated for  = 0.2. Find a value of  for the smallest MSE. Round your answer to three decimal places.
Using the simple exponential smoothing method (SESM), compute the forecasts for the February 2022 to March 2023 period. Use a smoothing constant of 0.2 and assume a forecast of 7 000 units for January 2022.Compute the three-month weighted moving average (3MWMA) forecasts for the April 2022 to March 2023 period, using weights of 0.2, 0.3, and 0,5 (oldest data to newest data, respectively).Using the forecasts calculated for the April 2022 to March 2023 period, calculate the Mean Absolute Percentage Error (MAPE) of the simple smoothing method and the MAPE of the three-month weighted moving average method.Which of the two methods should the demand planner use to forecast the volume of export of the next-Gen Ranger. Explain why?
