5.6.1.2 Control Parameters

The Profile and Trending Analysis screen shown in Figure 5-6
shows the control parameters that are provided for Profile
and Trending Analysis.

Report title: The title that appears on the reports.

Input file:   The CHN resource element file that was
              originally defined in the extended example in
              Section 3.3.3.1 of this guide.

Start date    The start date for date range selection.  Since
              neither a start date nor a number of days,
              weeks, or months are specified for this
              analysis, no date range selection is applied to
              the historical observations from the CHN
              resource element file.

SYSID:        Historical observations only for SYSID TSO1.

Zone:         The summary level selection criteria for the
              analysis.  Since the CHN resource element file
              was defined in Section 3.4.3.1 at the ZONE
              summary level, this parameter specifies that
              only historical observations for ZONE 1 are
              included in the analysis.

No. months:   The number of days, weeks, or months that will
              be included in the analysis.

Specify       Specify Y or N. The CHN resource element file
CAPAPU        was not defined as containing the CAPAPU data
Values:       element, therefore no CAPAPU value may be
              specified on this screen.

Forecast      The length of the forecast observation. Six is
length:       selected as a conservative number of estimates
              to be made from the 12 historical observations
              that are contained in the CHN resource element
              file.

Forecast      The type of forecast observation.  The six
type:         future observations to be forecast are
              calculated based on the long-term rate of
              growth.

Name, Page,   These parameters define the contents of the
Col.,         Column reports.  These parameters specify which
Heading,      and variables are tracked and provide column
Output        headings, report formats, and the page and
Format:       column sequence of variables on the reports.
              Note that the five channel percent busy data
              elements are specified to appear on the first
              page of the report and that the five channel
              I/O count data elements are specified to appear
              on the second page.
