Sample Chapter: Quantitative Analysis for Management, 12e Render Chapter 3 Decision Analysis 1 Expected monetary value EMV is the average or expected monetary outcome of a decision if it can be repeated a large number of times. Forecasting is as much an art as a science. Students should understand that qualitative analysis judgmental modeling plays an important role in predicting management future since not every factor can be quantified.
Sometimes the best forecast is done by seat-of-the-pants methods. Many managers want to know what goes on behind the forecast. They may feel uncomfortable with complex statistical models with too many variables. They also need to feel a part of the pro- cess. Most managers want to feel a part of the modeling process and appreciate the opportunity download provide input. Even if a firm has 10, products, the constants can be selected very quickly and easily without human interven- tion.
A 3-week moving average appears on the right. The forecast quantitative the edition of January 1 was units, whereas actual demand for out to be units. The demand forecasted for the week of January 8 is calculated as follows. To evaluate the accuracy of each smoothing constant, we can compute the absolute deviations and MADs. Assume that the forecast for Janu- pdf was 22 batteries. Alternative Example 5. We compute the tracking signal and MAD.
Forecast errors 70 MAD The steps that are used to develop any 12th system are: 1. Determine the use of the forecast. Select the items or quantities that are to be forecasted. Determine the time horizon of the forecast. Select the forecasting model.

Gather the necessary data. Validate the forecasting model. Make the forecast. Implement the results. A time-series forecasting model uses historical data to predict future trends.

The only difference between causal models and time-series models is that causal models take into account any factors that may influence the quantity being forecasted. Causal models use historical data as well. Time-series models use only historical data. Qualitative models 122th subjective factors into the forecasting model.
Judgmental models are useful when subjective factors are important. When quantitative data are difficult to obtain, qualitative models are appropriate.
The disadvantages of the moving average forecasting model are that the averages always 7. The Delphi technique involves analyzing the predictions that a group of experts have made, then allowing the experts to review the data again. This process may be repeated several times. After the final analysis, the forecast is developed. The group of experts may be geographically dispersed.
MAD is a technique for determining the accuracy of a forecasting model by taking mznagement aver- age of the absolute deviations. MAD is important because it can be used to help increase fore- casting accuracy. The number of seasons depends on the number of time periods that occur before a pattern repeats itself. For example, monthly data would have 12 seasons because there are 12 months in a year.
Quarterly data would have 4 seasons because there are 4 quarters in a year. Daily data would have 7 seasons because there are 7 days in a week. For daily data, it is common for many retail stores to have higher sales on Saturdays than on other days of the week, and a seasonal in- dex would reflect that. If a seasonal index equals 1, that season is just an average season.
The forecast based on the trend line fot the deseasonalized data is multiplied by the ap- donload seasonal index to adjust that forecast for the seasonal component. A centered moving average CMA should be used if trend is present in data. If an overall average is used rather than a CMA, variations due to trend will be interpreted as variations due to seasonal factors.
Thus, the seasonal indices will not be accurate. However, when weighted moving av- erages were used, the MAD was 5.

Once the actual forecasts have been made, their accuracy can be compared using the mean absolute differences MAD. Hale, University of Houston - Downtown. Overview Order Downloadable Resources Overview. Download Resources.
