Before the Gantt Chart

1909

Page 5: ASEM Tutorial on CPM - rdcpm

Gantt Charts are Easy to Read

Henry Gantt

Page 6: ASEM Tutorial on CPM - rdcpm

But if you want to make even a small change...

Page 7: ASEM Tutorial on CPM - rdcpm

...to the duration of one activity ... you have a great deal of work to perform to determine the impact

??

Page 8: ASEM Tutorial on CPM - rdcpm

CPM requires you to record the relationships between activities ... and allows the computer to

recalculate the impact of changes made ...

Page 9: ASEM Tutorial on CPM - rdcpm

... reducing the 40%+ rework effort to that of a keystroke

methodology then resource restraints•

set activities in required order •

gravity or essential requirements•

contract or command requirements•

calculate schedule to review opportunities •

allocate limited resources where supported by methodologies•

discretionary distribution of men, materials and equipment•

discretionary provision of staging areas, consumables and transport

Page 16: ASEM Tutorial on CPM - rdcpm

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

Page 17: ASEM Tutorial on CPM - rdcpm

"[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?

Page 38: ASEM Tutorial on CPM - rdcpm

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.”

Page 39: ASEM Tutorial on CPM - rdcpm

Activity Title

A gross abbreviation

Use logs to explain further

Limits of the CPM analysis -

no .or. statement

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

Page 45: ASEM Tutorial on CPM - rdcpm

The First 90 Days vs. the Last 90 Days

Page 46: ASEM Tutorial on CPM - rdcpm

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

Page 47: ASEM Tutorial on CPM - rdcpm

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

Page 48: ASEM Tutorial on CPM - rdcpm

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

Page 49: ASEM Tutorial on CPM - rdcpm

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

Page 50: ASEM Tutorial on CPM - rdcpm

What is an Event?

Page 51: ASEM Tutorial on CPM - rdcpm

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.”

Page 52: ASEM Tutorial on CPM - rdcpm

Durations

Page 53: ASEM Tutorial on CPM - rdcpm

Level of Detail and Duration Considerations

1. Set minimum unit of duration based upon usage.2. Minimum for most construction applications is ONE DAY.

Page 54: ASEM Tutorial on CPM - rdcpm

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.

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

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

Page 88: ASEM Tutorial on CPM - rdcpm

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

Page 89: ASEM Tutorial on CPM - rdcpm

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

RDM is now in Primavera’s Pertmaster v8.2

Page 91: ASEM Tutorial on CPM - rdcpm

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

Page 92: ASEM Tutorial on CPM - rdcpm

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

How about overlap of activities?

RDM permits overlaps of activities•

distinguishes SS2 from PS2, FF2 from FR2•

internally (invisibly) splits activities being overlapped by PS/FR restraints•

allows written description of “what portion of ‘A’

required for ‘B’”•

Description on restraint records assumptions•

for SS2 –

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?•

Other issues of overlapping activities•

RDM supports individual setting of interruptible/stretched/continuous•

RDM supports modified/retained/progress-override out-of-sequence logic

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

schedule updates relate progress/performance this past period–

includes AS, AF, RD, PCT, CostPCT–

AS & AF relate to schedule -

not cost -

can next task start?–

RD relates to estimate of work remaining -

not when scheduled–

special problems when PCT .ne. CostPCT–

special problems when updating activities out-of-sequence–

special problems for PDM Lead/Lag updating•

network revisions relate improved knowledge of future of project–

includes adding/modifying/deleting logic restraints–

includes adding/modifying/deleting constraints–

includes changing durations of activities not-yet-started

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

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 –

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

Page 146: ASEM Tutorial on CPM - rdcpm

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 Modified from The Combinatorial Mathematics of Scheduling by Ronald L. Graham

in Scientific American March 1978

Page 166: ASEM Tutorial on CPM - rdcpm

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!

Page 172: ASEM Tutorial on CPM - rdcpm

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.

Page 173: ASEM Tutorial on CPM - rdcpm

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

Page 175: ASEM Tutorial on CPM - rdcpm

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.
