Before the Gantt Chart
1909
Gantt Charts are Easy to Read
Henry Gantt
But if you want to make even a small change...
...to the duration of one activity ... you have a great deal of work to perform to determine the impact
??
CPM requires you to record the relationships between activities ... and allows the computer to
recalculate the impact of changes made ...
... reducing the 40%+ rework effort to that of a keystroke

Basic Rules of CPM
•
map methodology then allocate resources
+•
start of each activity must be preceded by something
•
finish of each activity must be followed by something
=•
each activity must be preceded by methodology
•
each activity must be followed by methodology•
rules for allocating resources are more flexible
"[E]xcept
in the middle of a battlefield, nowhere must men coordinate the
movement of other men and materials in the midst of such chaos and with such
limited certainty of present facts and future occurrences as in a huge construction
project ..."

What is an Activity?
An activity is ...
“...a set of instructions, given to a competent foreman, who is then expected to complete such without further supervision or interaction with other than his own subordinates.”
Activity Title
•
A gross abbreviation
•
Use logs to explain further
•
Use code fields SHT1, SHT2 to refer to design engineer’s drawings
•
A gross abbreviation–
Form/Rebar/Pour Wall shown on Dwg C27 and Dwg C28 Section B upon
completed foundations for the purpose of supporting joists and including sleeves for plumbing and electrical penetrations.

Activity title further defined by predecessor and successors
•
Hard physical logic vs. soft resource logic vs. no logic–
Each activity must have at least one physical relationship in and out–
Each activity should have only one resource restraint per resource–
Explain and record reasons for non-physical restraints as notes or in logs–
Explain and record reasons for any constraints as notes or in logs
Physical v. Limited Resources v. Leveled Resources
The First 90 Days vs. the Last 90 Days
The First 90 Days vs. the Last 90 Days•
Detail of latter part of project is often deferred
•
Detail of less knowledgeable areas is often deferred, such as:–
Architectural, HVAC and plumbing of control building of a process plant–
Electrical connections and instrumentation
•
Engineer is often sloppier on end items
•
Project manager will never have more time than at the start of project
•
The forward pass: Why is this task necessary for the next?–
Hard logic vs. resource restraints vs. placemarker –
How hard is the hard logic? ...on a scale of 1 to 10?–
Purpose of resource logic—question of entitlement–
SNET constraints—question of entitlement –
FNLT constraints—usually mandated by owner
Now -
let’s walk through the project and check the logic
•
The backward pass: Are we missing any requirements for this task?–
Contractor —
owner —
third party activities–
Physical vs. access vs. limited resource restraints–
Calendar considerations—seasonal weather, etc.
?
Let’s walk through the project and check the logic
The Plan vs. the Schedule
•
Use the pure-logic diagram as basis for all calculations
•
Use calculated schedule as tabular and graphical depictions for analysis
•
Then evaluate manual and automated leveling and smoothing routines
What is an Event?
An event is ...
“... an event is a point in time which represents a condition or set of conditions may verifiably be determined to have been met. An event does not have a duration, start or finish, but rather occurs on a specific day, date or time.”
Durations
Level of Detail and Duration Considerations
1. Set minimum unit of duration based upon usage.2. Minimum for most construction applications is ONE DAY.

1. Set minimum unit of duration based upon usage.2.
Minimum for most construction applications is ONE DAY.3.
Minimum for many maintenance/turnover applications is 15 MINUTES4.
Minimum for some computer applications is ONE CLOCK TICK5.
Activities which are too short must be combined or absorbed into the definition of a preceding or succeeding activity.

Activity Duration
•
Estimate based on knowledge of superintendent
•
Use resource type and size to define basis of duration, or
•
Use CrewType and CrewSize codes to define basis of duration
Duration 10 Duration 2
Activity Costs
•
For scheduling and not accounting purposes
•
Cross-check against estimate to see if anything has been omitted:–
Labor concerns: leveling and smoothing–
Material orders: equipment vs. bulk items–
Misc. costs: physical preparations

More About Logic
Logic Restraints and Relationshipsbetween Activities and Events
Variants of CPM•
ADM –
AOA –
Arrow Diagramming Method•
developed in 1956 –
for computers limited by “linear access memory”•
activity resides on arrow between two event nodes•
activity is logic between two events •
additional “dummy”
logic required –
no duration or description•
supports only finish-to-start restraints between activities
•
PERT –
Program Evaluation Review Technique•
developed in 1958 –
for computers limited by “linear access memory”•
events are defined –
activities are not defined •
events connected to others by logic restraints with durations•
events do not have a “start”
or “finish”
–
events “occur”•
supports only occurs-to-occurs restraints between events
Limitations of Early Computers
Graphic depiction of early computers utilizing “linear access memory”from Hansen BJ, Practical PERT,
1964, America House
Variants of CPM•
PDM –
AON –
Precedence Diagramming Method •
developed in 1964 –
for computer of limited RAM and CPU speed•
activity is discrete node –
connected to others by logic restraints•
supports FS, SS, FF and SF restraints between activities•
some mainframe systems also supported BB and EE (PS and FR) restraints•
does not support events or true milestones
•
RDM –
Relationship Diagramming Method •
developed in 2004 –
for modern computers with fewer limitations•
activity resides between two event nodes –
may include other events•
events (at start, finish, within activity) are connected by logic restraints•
supports FS, SS, PS, FF, FR, SF restraints between activities / events•
records additional text and code data on restraints / activities
/ events
What is RDM? Relationship Diagramming Method
Introduction by James J. O’Brien
•
Kelley expected more from CPM
but was limited by early computers
•
free and independent float•
RDM created ~ 2003 to
2005•
“amazing grasp of the obvious”•
“what Kelley was looking for”
Improving CPMRestoring the Original Promise
Relationship Diagramming MethodRDM requires you to record the relationships between activities ...
... and allows the computer to recalculate the impact of changes made ...
... reducing the 40%+ rework effort to that of a keystroke
more about
RDM is now in Primavera’s Pertmaster v8.2
What are the limits of CPM?•
Basic concept of CPM is finish-to-start•
start of activity must follow finish of something else •
finish of activity must be followed by start of something else •
Basic concept of CPM is plan then schedule•
unlike basic Gantt charting –
later check for necessary methodology•
prepare logic for necessary methodology before logic for resources•
Logic rules for mathematics of CPM•
start of each activity must follow physical completion of something else•
finish of each activity must be physically required for something else•
calculates ES, EF, LS, LF, TF for unlimited resources•
add resource logic –
leading to start of, from finish of
–
each activity•
calculates Scheduled Start and Finish –
may report as ES, EF
How about overlap of activities?
•
ADM does not permit overlaps of activities•
ADM only supports finish-to-start restraints between activities•
PDM permits overlaps of activities•
PDM supports FS, SS, FF, SF restraints•
PDM overlaps abbreviate assumptions•
for SS2 –
exactly what 2 day portion of predecessor must be finished?•
does not distinguish “2 days after”
and “after 2 days performed”•
for FF2 –
exactly what 2 day portion of successor cannot be started?•
does not distinguish “finish 2 days after”
and “finish last 2 days after”•
other issues of PDM relate to continuous/interruptible activities•
other issues of ADM and PDM relate to out-of-sequence performance

exactly why ‘B’
cannot start until 2 days after start of ‘A’•
for PS2 –
exactly what 2 day portion of ‘A’
must be finished?•
for FF2 –
exactly why ‘B’
cannot finish until 2 days after finish of ‘A’•
for FR2 –
exactly what 2 day portion of ‘B’
cannot be started?•

Additional code data on restraints
•
Reason/Why –
Physical or Resource?•
first plan the methodology –
what must be finished
before this start•
walls before roof –
wiring before terminations –
software before test•
why? –
gravity v owner-directive? -
immutable v false-work? –
costs?•
record this information when preparing the plan•
then schedule the resources –
crew/craft/equipment/forms/material/…•
EACH activity must be preceded/succeeded by physical restraint•
but
ONLY ONE resource restraint (per resource) to/from an activity•
Benefits of use of Reason/Why Code•
physical “open end”
diagnostic –
duplicate “resource assigned diagnostic•
“what if”
additional crews or equipment or forms or …
provided•
“what if”
false-work or relaxed specifications utilized•
more robust resource leveling software
Additional code data on restraints•
Just-in-Time Physical Restraint•
distinguish “prevent delaying project”
/ “prevent delaying work crew”•
calculate new attributes JLS, JLF, JTF

Actual Start and Finish Dates
•
Activity starts after predecessors complete•
Off-site and on-site fabrication and preparation is not part of activity
•
Activity is finished when successor activity may begin•
Touch-up and repair not required for successor is not part of activity
Original v Remaining Duration
•
Basis of OD
is estimated original scope / (anticipated resources x productivity)•
Basis of RD
is estimated remaining scope / (anticipated resources x productivity)
•
Scheduled (Early) Start is either calculated or constrained
for initial or update•
Actual Duration (AD) is measured number of days worked –
not span of time

Risk and Monte Carlo Simulation
•
allow you to set the probability of days being non- working in specified date ranges.
•
Before each iteration of the risk analysis, the calendar will be set up with non-working days using the percentages and dates that have been entered.
•
This will affect the scheduling of any tasks that are using the calendar directly, or indirectly via a resource.
•
Probabilistic Calendars
•
Duration Distributions may be Correlated
•
Adding correlation helps you avoid modeling situations that are not realistic. In the above example correlating the durations of the tasks will ensure that the unlikely situation where one task is done very quickly and the other task takes a long time does not occur.
•
The correlation between risks can be any value between -100% and +100%.
• Two tasks in a project are similar and experience has shown that if one task takes a long time then it is likely that the other will to.
• This is an example of a positive correlation between the task durations.

How much longer is the calculated leveled schedule than the optimum?•
Worst Case where available resources are increased:
T2 < T1(1 + [r1 -
1]/r2)for: •
T1 = original project duration•
T2 = revised project duration after leveling•
r1 = original number of resource units available•
r2 = increased number of resource units available

Theoretical Limits of Algorithms
•
Worst Case without increasing resources –
due entirely to poor choice of priority list–
therefore reduce number of variables: r = r2 = r1 Y
T2
< T1(2 -
1/r)
•
thus for 2 crews, worst case is T2 < T1 x 1.50•
thus for 3 crews, worst case is T2 < T1 x 1.67•
thus for 4 crews, worst case is T2 < T1 x 1.75•
thus for n crews, worst case is T2 < T1 x 1.99 < T1 x 2
•
Leveled schedule may be up to double the length of optimal schedule!

Still a NP Complete Problem - No Known Optimum Solution
1 P3 sorts the entire network
into a logical sequence of activities to find the first activity
or activities without unsatisfied predecessor relationships. These activities are ready for leveling. In the event of a tie, P3 uses the priority specification as the tiebreaker. In the event that prioritization values are also tied, P3 sorts by activity ID.
2 P3 initially assumes the normal resource limits. P3 deducts from the available resource pool any resources that activities in progress are using.
3 P3 checks that there will be sufficient resources available to
satisfy the activity's demands for its entire duration. If so, P3 schedules the activity and returns to step 1. If not, the leveling process continues with step 4.
4 If the activity has no positive total float, P3 goes to step 5; otherwise, it delays the activity's start by one workperiod
and re-examines the resource availability during each workperiod of the activity. If there are always sufficient resources available, P3 schedules
the activity and goes back to step 1.
If not, it repeats step 4 until the total float is exhausted.
5 When P3 reaches step 5, the positive float of the activity has
been exhausted without finding sufficient resources to schedule
the activity under the normal resource limits. P3 tries to schedule the activity again, using the activity's original, early scheduled date, but this time assuming a higher resource availability, returning to step 3. The choice of higher resource level is based upon user choice of smoothing function.
6 If the leveling process reaches step 6, P3 could not schedule the activity within its total float, even assuming the maximum resource availability. As a result, P3 delays the activity beyond its total float. This means that the activity will delay the project's completion. P3 continues to assume the maximum resource availability, and delays the activity one workperiod at a time, each time checking to see if sufficient resources are available during each workperiod of the activity. If P3 never finds enough resources, looking as far into the future as available memory allows, P3 schedules the activity on its original, early schedule dates, and issues a warning message in the leveling analysis report advising you that the activity could not be leveled

SureTrak
If P3 previously reached step 5 with this activity, it skips this step and goes directly to step 6.
When P3 reaches step 5 for the first time, the positive float of
the activity has been exhausted without finding sufficient resources to schedule the activity under the normal resource limits. P3 tries to schedule the activity again, using the activity's original, early scheduled date, but this time assuming a higher resource availability.
How much higher? This depends on whether or not resource smoothing
is in effect, and if it is, which smoothing option you selected
in the Smoothing section of the Resource Leveling dialog box. There are three smoothing options: None, Non-time Constrained, and Time Constrained. All three options lead back to step 3. Choose None
and P3 assumes the maximum resource availability. Choose Non-time Constrained
and P3 assumes an increase in resource availability of ten percent of the difference between the normal and maximum limits. Choose Time Constrained
and P3 assumes double the maximum resource availability.
