Title: ms4102ch1.PDF Forecasting Techniques: Demand forecasting is a difficult exercise. Consumers’ behaviour is the most unpredictable one because it is motivated and influenced by a multiplicity of forces. The rst two types of scale we address are that business forecasting methods should be suitable for 1) a large number of people making forecasts, possibly without training in time series methods; and 2) a large variety of forecasting problems with potentially idiosyncratic features. These can be classified into four broad categories: qualitative, time-series, causal models, and technological forecasting. The most common methods used in smoothing techniques of demand forecasting are simple moving average method and weighted moving average method. What is the purpose of the forecast—how is it to be used? Role of Forecasting 3. /Filter /FlateDecode demand, this is the type of forecasting that is emphasized in our textbook and in this course.TYPES OF FORECASTING METHODS Qualitative methods: These types of forecasting methods are based on judgments, opinions, intuition, emotions, or personal experiences and are subjective in nature. 1.

Forecasting Techniques for Time Series Time Series Assumptions A time series is a set of observations xt each being recorded at a specific time t.In a continuous-time time series, the observations are made continuously during a specified time interval. Quantitative forecasting can be applied when two conditions are satisﬁed: 1. numerical information about the past is available; 2. it is reasonable to assume that some aspects of the past patterns will continue into the future. Qualitative methods 4. This is almost never true.Successful forecasting begins with a collaboration between the manager and the forecaster, in which they work out answers to the following questions.
