Determine the purpose of the forecast and when it will be needed. This will provide an indication of the level of detail required in the forecast‚ the amount of resources (manpower‚ computer time‚ dollars) that can be justified‚ and the level of accuracy necessary. 2.

This paper will show the data in an index using the time series data to forecast inventory for the next year. The Winter Historical Inventory Data from the (University of Phoenix‚ 2010) shows four years of actual demand of inventory data for the seasonal Winter Highs. Each year is divided into 12 month increments. Methods This breakdown of data allows for quantitative analysis. This approach is objective in nature compared to qualitative analysis which is developed using the judgment of experts

Approaches to Forecasting Are based on analysis of historical data concerning one or more time series. Time series - a set of observations measured at successive points in time‚ or over successive periods of time. If the historical data: • are restricted to past values of the series we are trying to forecast‚ it is a time series method. 1 Components of a Time Series 1) Trend component - the gradual shifting of the time series over a long period of time. 2) C li l component - any regular
