RESOURCE Statement
The following new or updated options are available in the RESOURCE
statement:
-
ADDCAL
- requests that a variable, _CAL_, be added to the Resource Schedule
data set that identifies the resource calendar for each resource
used by each activity. For observations that summarize the
activity's schedule, this variable identifies the activity's calendar.
-
MULTIPLEALTERNATES
- MULTALT
-
indicates that multiple alternate resources can be used to substitute
for a single resource. In other words, if one of the alternate resources
is not sufficient to substitute for the primary resource, the procedure will use
other alternates, as needed, to fulfill the resource requirement.
For example, if an activity needs 1.5 programmers
and the allowed alternates are JOHN and MARY, the procedure will use
JOHN (at rate 1) and MARY (at rate 0.5) to allocate a total of 1.5 programmers.
See the "Specifying Multiple Alternates" section for details.
-
OBSTYPE=variable
-
specifies a character variable in the Resource
data set that contains the type identifier for each observation.
Valid values for this variable are RESLEVEL, RESTYPE, RESPRTY,
SUPLEVEL, ALTRATE, ALTPRTY, RESRCDUR, CALENDAR, MULTALT, MINARATE, and
AUXRES.
If OBSTYPE= is not specified, then all
observations in the data set are assumed to denote the levels of the
resources, and all resources are assumed to be replenishable and
constraining. The observation types, MULTALT, MINARATE, and AUXRES, are
new in Release 8.1 and are described in the "Enhancements to the Resource Data Set" section.
-
RESID=variable
-
specifies a variable in the RESOURCEIN= data set that indicates the
name of the resource variable for which alternate resource information
or auxiliary resource information is being specified in that
observation. The specification of auxiliary resource information is new
in Release 8.1.
Recall that observations that indicate alternate resources are
identified by the values ALTRATE and ALTPRTY for the OBSTYPE variable.
These values
indicate whether the observation specifies a rate
of substitution or a priority for substitution; the value
of the RESID variable in such an observation indicates the
particular resource for which that observation specifies alternate
resource information.
Recall also that the specification of the RESID= option
triggers the use of alternate resources. See
the "Specifying Alternate Resources" section in
the chapter "The CPM Procedure" of the SAS/OR User's
Guide: Project Management for further information.
Now observations indicating auxiliary resources are
identified by the value AUXRES for the OBSTYPE variable. In such
observations, the value of the RESID variable specifies
the name of the primary resource while the values of the other
resource variables specify the rate of auxiliary resources needed for
every unit of the primary resource.
See the "Auxiliary Resources" section for further information.
