A forecast is a statement about the uncertain future (such as weather forecast). In business, forecasts are mainly used to predict demands, so we focus on this aspect. There are two types of forecasting methods, one is qualitative forecasting, and another is quantitative forecasting. 1. Qualitative forecasting (a.k.a. judgmental

They do not rely on any rigorous mathematical computations. Quantitative methods: These types of forecasting methods are based on mathematical (quantitative) models, and are objective in nature.

If forecasting staffing, we could use data from the last four weeks where Tuesdays are to be forecast. Weighting on Tuesdays is: T-1 is .25; T-2 is .20; T-3 is .15; T-4 is .10 and Average of all other days is weighed .30. Exponential Smoothing Method. A type of weighted moving average that applies declining weights to past
