OM Class Notes: 3/1/06

Note Takers: Thomas Molesky & Catherine Palma

·        What did we do last class?

o       Tables

o       Diagram

·        Network Diagramming

o       Timing is given

o       Discuss Catherine’s Homework

o       Discussed about the way Catherine Diagrams CPM

·        CPM

o       Calculate the Early Start and the Late Finish

o       Example

§         Early – Add

§         Late – Subtract

o       Main idea: Find slack by knowing values

·        Why do we need to find slack?

o       That node is in the critical path

o       Determine node that has a slack of zero

§         Can’t play around

·        Two values difficult to find à Know these 2

o       Early Start

o       Late Finish

·        Project should not be more than 27 weeks

o       Concept

·        Two things are the hardest part

o       Early Start

o       Late Finish

·        Chapter 3 focuses on this

o       Book

o       No book – SEE THE BOOK SITE IN THE POWER POINT SLIDESHOW

·        +1 Saeed

·       

o       Passed time table activity

§         ES + 2 = 2

§         Assumption

      If LF = 11, then LS = 9

      Activity – LF = 11 – 2 = 9

§         Try to make some sense out of it

·        2 Things

o       Early Start & find Late Finish

o       Early start is the problem

·        2 Passes

o       Forward Pass

§         Early start is difficult

o       Backward Pass

·        What would be the early start?

o       Zero

o       ES for the first node isn’t difficult

·        The formula of ES

o       ES = Max(EF of all immediate predecessors)

·        Went over power points

o       Ch. 6

o       Ch. 3

·        If you have LF, what is the late start?

o       LF – Activity

STOP @ 9:37 PM
