Competition environment 4.9.2 How –simulation method There are many ways to create a forecast for a certain goods that a planner can use just one or combine many methods together. According to Chopra and Meindl define these methods as follows: 1. Qualitative methods Rely upon a person’s intuition or subjective opinions about a market. These methods are most appropriate when there is not much historical data to work with. 2. Causal methods assume that demand is strongly related to a particular

on data from the past and present and analysis of trends. Forecasting entails the use of historic data to determine the direction of future trends. Forecasting is used by companies to determine how to allocate their budgets for an upcoming period of time. This is typically based on demand for the goods and service it offers compared to the cost of producing them. Investors utilize forecasting to determine if events affecting a company‚ such as sales expectations will increase or decrease the price

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

.2.3 Time series models Time series is an ordered sequence of values of a variable at equally spaced time intervals. Time series occur frequently when looking at industrial data. The essential difference between modeling data via time series methods and the other methods is that Time series analysis accounts for the fact that data points taken over time may have an internal structure such as autocorrelation‚ trend or seasonal variation that should be accounted for. A Time-series model explains
