From the information gathered a prediction for the forecast can be made. Exponential smoothing: The alpha method of 0.95 would work here. The formula would look like this: NF=LF + a (LD- LF) Last Forecast (LF) = $6‚300‚000 Last Data (LD) =

PRODUCTION & OPERATIONS MANAGEMENT Forecasting helps managers and businesses develop meaningful plans and reduce uncertainty of events in the future. Managers want to match supply with demand; therefore‚ it is essential for them to forecast how much space they need for supply to each demand. 1.1 QUANTITATIVE TECHNIQUES * LINEAR TREND Show steady‚ straight-line increases or decreases where the trend-line can go up or down and the angle may be steep or shallow

the text‚ exercise 9.1 provides data for Palmdale Human Services. In this exercise it asks for the 20X5 figures using several forecasting models. The process of find 20X5 will include the use of moving averages‚ weighted moving averages‚ and exponential smoothing. The Palmdale Human Services personal expenses for the past four years are represented in the following data: Fiscal Year | Expense | 20X1 | $5‚250‚000 | 20X2 | $5‚500‚000 | 20X3 | $6‚000‚000 | 20X4 | $6‚750‚000 | For moving averages

TIME SERIES MODELS Time series analysis provides tools for selecting a model that can be used to forecast of future events. Time series models are based on the assumption that all information needed to generate a forecast is contained in the time series of data. The forecaster looks for patterns in the data and tries to obtain a forecast by projecting that pattern into the future. A forecasting method is a (numerical) procedure for generating a forecast. When such methods are not based upon
