When changes occur to a schedule, you have to adjust the activity
starting dates manually if you use PROC CALENDAR to produce a schedule calendar.
Alternatively, you can use PROC CPM in SAS/OR software to reschedule work
when dates change. Even more important, you can provide only an initial starting
date for a project and let PROC CPM calculate starting dates for activities,
based on identified successor tasks, that is, tasks that cannot begin until
their predecessors end.
In order to use PROC CPM, you must
-
create an activities data set that contains activities with durations.
(You can indicate nonwork days, weekly work schedules, and work shifts with
holidays, calendar, and work-shift data sets.)
-
indicate which activities are successors to others (precedence
relationships).
-
define resource limitations if you want them considered
in the schedule.
-
provide an initial starting date.
PROC CPM can process your data to generate a data set that contains
the start and end dates for each activity. PROC CPM schedules the activities,
based on the duration information, weekly work patterns, work shifts, as well
as holidays and nonwork days that interrupt the schedule. You can generate
several views of the schedule that is computed by PROC CPM, from a simple
listing of start and finish dates to a calendar, a Gantt chart, or a network
diagram.
This example
-
calculates a project schedule containing multiple calendars (PROC
CPM)
-
produces a listing of the PROC CPM output data set (PROC PRINT)
-
displays the schedule in calendar format (PROC
CALENDAR).
This example features PROC CPM's ability to calculate a schedule that
-
is based on an initial starting
date
-
applies different non-work periods to different calendars, such
as personal vacation days to each employee's schedule
-
includes milestones (activities with a duration of 0).
This example introduces users of PROC CALENDAR to more advanced SAS
scheduling tools. For an introduction to project management tasks and tools
and several examples, see Project Management Using the SAS System.
For more examples, see SAS/OR Software: Project Management Examples. For complete reference documentation, see
SAS/OR User's Guide: Project Management.
