ACTIVITY PLANNING
Prof. Kanchana Devi
Network Planning Models
Prof. Kanchana Devi
2
 Scheduling techniques model the project’s activ ities and
their relationships as a “Network”.
 In network time flows from left to right
 These techniques were developed in 1950’s
 There are two best techniques:
 CPM (Critical Path Method)
 PERT (Program Evaluation Review Technique)
 Both uses an “activity-on-arrow” approach
 Activities are drawn as arrows joining circles, or nodes
 Which show the start and completion time of the activities
Precedence Network
Prof. Kanchana Devi
3
 Recently used , Popular one
 It uses “activity-on-node” networks
 Where activities are represented as nodes
 Links between the nodes are represented as
sequencing requirements.
Formulating a Network Model
Prof. Kanchana Devi
4
 First stage:
 Representing the activities and their
relationships as graph.
 In “Activity-on-node”
 Representing the activities as nodes(boxes) and
the lines between nodes represent the
dependencies.
Rules:Constructing Precedence
Network
Prof. Kanchana Devi
5
 A project network should have only one start
node
 A project network should have only one end
node
 A node has a duration
 Links normally have no duration
 Precedents are the immediate preceding
activities
 Time moves from left to right
 A network may not contain loops
 A network should not contain dangles

Representing Lagged Activities
Prof. Kanchana Devi
10
 Undertake two activities in parallel as there
is a lag between two.
 Activities are lagged because a stage in one
activity must be completed before the other
may proceed.
 Show each stage as separate activity.
Adding Time Dimension
Prof. Kanchana Devi
11
 Each activity have an estimate of its duration.
 Forward pass – Earliest dates at which
activities may commence and project be
completed.
 Backward pass – Latest start dates for
activities and critical path.

14
Dummy activities
15
 When two paths within a network have a
common event to occur.
 It is incorrect to require both hardware
specification and data structure design
Using Dummy Activities
Prof. Kanchana Devi
16
…….
Prof. Kanchana Devi
17
 Dummy activities shown as dotted lines have
a zero duration and use no resources.
 Use of dummy activity where two activities
share the same start and end nodes makes it
easier to distinguish activity end points.

Identifying the Critical Path
Prof. Kanchana Devi
24
 Any delay on the critical path will delay the
project.
 Difference between earliest and latest date
for an event is known as slack.
 Event with slack of zero is critical as any
delay in achieving that event will delay the
completion date of the project.

Activity Float
Prof. Kanchana Devi
26
 As events have slack, activities possess float.
 Total float is the difference between earliest
start and latest start ( or difference between
earliest finish and latest finish)

  • 2. Network Planning Models Prof. Kanchana Devi 2  Scheduling techniques model the project’s activ ities and their relationships as a “Network”.  In network time flows from left to right  These techniques were developed in 1950’s  There are two best techniques:  CPM (Critical Path Method)  PERT (Program Evaluation Review Technique)  Both uses an “activity-on-arrow” approach  Activities are drawn as arrows joining circles, or nodes  Which show the start and completion time of the activities
  • 3. Precedence Network Prof. Kanchana Devi 3  Recently used , Popular one  It uses “activity-on-node” networks  Where activities are represented as nodes  Links between the nodes are represented as sequencing requirements.
  • 4. Formulating a Network Model Prof. Kanchana Devi 4  First stage:  Representing the activities and their relationships as graph.  In “Activity-on-node”  Representing the activities as nodes(boxes) and the lines between nodes represent the dependencies.
  • 5. Rules:Constructing Precedence Network Prof. Kanchana Devi 5  A project network should have only one start node  A project network should have only one end node  A node has a duration  Links normally have no duration  Precedents are the immediate preceding activities  Time moves from left to right  A network may not contain loops  A network should not contain dangles
  • 6. Fragment of precedence Network Prof. Kanchana Devi 6 Install Program Test Data Take-on Code
  • 7. A loop represents an impossible sequence Prof. Kanchana Devi 7 Code Program Release Program Test Program Diagnose Errors Correct Errors
  • 8. A Dangle Prof. Kanchana Devi 8 Design Program Install Program Test Program Code Program Write User Manual
  • 9. Resolving the Dangle Prof. Kanchana Devi 9 Design Program Install Program Test Program Code Program Write User Manual Sign-Off
  • 10. Representing Lagged Activities Prof. Kanchana Devi 10  Undertake two activities in parallel as there is a lag between two.  Activities are lagged because a stage in one activity must be completed before the other may proceed.  Show each stage as separate activity.
  • 11. Adding Time Dimension Prof. Kanchana Devi 11  Each activity have an estimate of its duration.  Forward pass – Earliest dates at which activities may commence and project be completed.  Backward pass – Latest start dates for activities and critical path.
  • 13. Project Activity Network Prof. Kanchana Devi 13
  • 14. Project Activity Network represented as CPM Network Prof. Kanchana Devi 14
  • 15. Dummy activities 15  When two paths within a network have a common event to occur.  It is incorrect to require both hardware specification and data structure design
  • 16. Using Dummy Activities Prof. Kanchana Devi 16
  • 17. ……. Prof. Kanchana Devi 17  Dummy activities shown as dotted lines have a zero duration and use no resources.  Use of dummy activity where two activities share the same start and end nodes makes it easier to distinguish activity end points.
  • 18. Forward Pass Prof. Kanchana Devi 18 Activity Duration (Weeks) Earliest Start Date (Weeks) Earliest Finish Date(Weeks) A 6 0 6 B 4 0 4 C 3 6 9 D 4 4 8 E 3 4 7 F 10 0 10 G 3 10 13 H 2 9 11
  • 20. A CPM Network after forward pass Prof. Kanchana Devi 20
  • 21. Activity table for forward pass Prof. Kanchana Devi 21 Activity Duration (weeks) Earliest Start Date Latest Start Date Earliest Finish Date Latest Finish Date Total Float A 6 0 6 B 4 0 4 C 3 6 9 D 4 4 8 E 3 4 7 F 10 0 10 G 3 10 13 H 2 9 11
  • 23. CPM Network after the backward pass Prof. Kanchana Devi 23
  • 24. Identifying the Critical Path Prof. Kanchana Devi 24  Any delay on the critical path will delay the project.  Difference between earliest and latest date for an event is known as slack.  Event with slack of zero is critical as any delay in achieving that event will delay the completion date of the project.
  • 25. Critical Path Prof. Kanchana Devi 25 Event Number Latest Date Earliest Date Slack
  • 26. Activity Float Prof. Kanchana Devi 26  As events have slack, activities possess float.  Total float is the difference between earliest start and latest start ( or difference between earliest finish and latest finish)
  • 27. Activity Schedule showing total float for each activity Prof. Kanchana Devi 27
  • 28. Activity Schedule Prof. Kanchana Devi 28 Actvity Name Time Actvity Name Time 1-2 A 4 5-6 G 4 1-3 B 1 5-7 H 8 2-4 C 1 6-8 I 1 3-4 D 1 7-8 J 2 3-5 E 6 8-10 K 5 4-9 F 5 9-10 L 7
