10. BUSINESS ELEMENT FORECASTING › 10.5 Component Operation

10.5 Component Operation

The Component Operation Section describes control parameters
that you can used to build the Business Element Forecasting
analysis inquiries.  These parameters allow you to create
regression models that relate the resource consumption of an
application to user-supplied business elements using stepwise
multivariate regression, optionally making use of selective
data deletion.

You can produce forecasts with these models using estimates
of future business element volumes which you have obtained
either from internal business sources or by using one of the
forecasting routines of this component.  Estimates you enter
in the business element history file are recognized by
Business Element Forecasting as future estimates by the fact
that the DATE data element contains date values greater than
the current date when you execute the analysis.

Estimates produced by one of the component forecasting
routines are stored in the forecast files (CPFxxx01) and are
recognized by the FILE_NO data element, which is 11 if the
observation is a future estimate and 12 if the observation is
confidence range.  Business Element Forecasting always uses
the future estimates you provide rather than those produced
by the forecasting routines of this component if both are
present.

You can optionally store the forecasts produced by Business
Element Forecasting in the resource element forecast file
corresponding to the dependent file.

Chapter 3 contains detailed descriptions of the screens and
procedures necessary to build a business element file, along
with descriptions of the methods available for building and
updating resource element files.

Because of the optional feature of selective data deletion,
you may need to use two screens to develop a business element
forecast.  The following sections discuss the use of each of
these screens.
