Example 2.15: Resource Allocation
In the previous example, a summary of the resource utilization is
obtained. Suppose that you want to schedule the project subject
to constraints on the availability of ENGINEERS. The activity data, as in
Example 2.14, are assumed to be in a data set named WIDGRES.
The resource variable, engineer, specifies the number of engineers
needed per day for each activity in the project.
In addition to the resource engineer, a consumable resource
engcost is
computed at a daily rate of 200 for each unit of resource
engineer
used per day. The following DATA step uses the Activity data set
from Example 2.14 to create a new Activity data set that includes
the resource engcost.
data widgres;
set widgres;
if engineer ^= . then engcost = engineer * 200;
run;
Now suppose that the availability of the resource engineer
and the total outlay for engcost is saved in a data set named
WIDGRIN, displayed in Output 2.15.1.

In the data set WIDGRIN, the first observation indicates that
engineer is a replenishable resource, while engcost is a
consumable resource.
The second observation indicates that an extra engineer is available, if
necessary.
The remaining observations indicate the availability profile starting
from
December 2, 1991. PROC CPM is then used to schedule the project
to start on December 2, 1991, subject to the availability as specified.

In the first invocation of PROC CPM, the scheduling rule used for
ordering the activities to be scheduled at a given time
is specified to be SHORTDUR.
The data set WIDGSCHD, displayed in Output 2.15.2,
contains the resource
constrained start and finish
times in the variables S_START and S_FINISH. On December 9,
three activities
can be scheduled, all of which require the resource engineer.
Using the
scheduling rule specified, PROC CPM schedules the activities with the
shortest durations first; thus, the activity `Drawings' is delayed by
five working days, until December 16, 1991.
The DELAYANALYSIS option in the RESOURCE statement helps analyze
the cause of the delay by adding three new variables to the
Schedule data set, R_DELAY, DELAY_R, and SUPPL_R.
In this example,
the R_DELAY and DELAY_R variables indicate that there is a delay of
five days in the activity `Drawings' due to the
resource engineer. Such information helps to pinpoint the source of
resource insufficiency, if any. Note that other activities that
follow `Drawings' also
have S_START>E_START, but the slippage in these activities is not
caused by resource insufficiency, it is due to their predecessors being
delayed. Note that the entire project is delayed by
five working days due to resource constraints
(the maximum value of S_FINISH is 18MAR92, while the maximum
value of E_FINISH is 11MAR92).
Note also that in this invocation, the DELAY= option is not specified;
therefore, the supplementary level of resource is not used,
since the primary levels of resources are found to be sufficient to schedule
the project by delaying some of the activities.

The data set WIDGROUT, displayed in Output 2.15.3,
contains variables Rengineer
and Aengineer in addition to the variables Eengineer and
Lengineer.
The variable Rengineer
denotes the usage of the resource engineer corresponding to the
resource-constrained schedule, and Aengineer denotes the remaining
level of the resource after resource allocation. For the consumable
resource engcost, the variables Eengcost, Lengcost,
and Rengcost
indicate the rate of usage per unit routinterval
(which defaults to
INTERVAL=WEEKDAY, in this case) at the start of the time interval
specified in the variable _TIME_. The variable Aengcost
denotes the
amount of money available at the beginning of the time specified in
the _TIME_ variable.

The second invocation of PROC CPM uses a different scheduling rule
(LST, which is the default scheduling rule). Ties are broken using
the L_START times for the activities. In this example, this rule results
in a shorter project schedule. Once again the variables DELAY_R
and R_DELAY indicate that the resource engineer
caused the activity
`Anal. Market' (`Prototype') to be delayed by five
days (three days).
However, the entire project is delayed only by three working days because
the activity `Anal. Market' is not a critical activity, and delaying
it by five days did not affect the project completion time. The schedule and
the resource usage data sets are displayed in Output 2.15.4 and
Output 2.15.5, respectively.
