whats the question?
red wise manufacturing company would like to assess the activities completion time of predecessors for building a new convention centre. these are outlined in the table below activities] immediate predecessor] duration(months) A - 3 B A 4 C A 6 D B 6 E B 4 F C 4 G D 6 H E,F 8 Required: draw a full timed network diagram to depict the information. identify the critical path calculate the EST and LFT for each activity , show these on network diagram and then transfer them to a table where you will also show the float on each non-critical activity.
i'm having a problem calculating the critical path because there is a dummy activity in the network diagram
so wht is the problem with dummy?
there are two situations when dummy appears.. 1. IF WE HAVE TWO ACTIVITIES HAVING SAME HEAD AND TAIL EVENT WITH DIFFERENT CONSUMPTION OF TIME THEN ALWAYS WE SHOULD INTRODUCE DUMMY RELATION. 2. IF ANY ACTIVITY APPEARS ATLEAST TWO TIMES IN PRECEDING COLUMN, I IN INDIVIDUAL AND II WITH OTHER ACTIVITY, THEN WE SHOULD INTRODUCE DUMMY.
IN YOUR QUESTION I THINK THERE WOULD NOT BE ANY DUMMY ACTIVITY AS NEITHER OF TWO SITUATIONS ARE APPLICABLE
ok so what then would be the critical path?
i think remaining you can find.. okk
thanks but i'm still having problem working out the floats and may i ask what do you think is the critical path?
drawing not so good but thats what i got and where the arrow is pointed is the dummy activity can someone calculate the EST and LFT
hey i sent u a pdf file have u gone thru that one
i gone through it but something kinda seems wrong because remember each letter has to depend on another look at it again
each letter need to have its own node(circle) they can't share
hey if i m not wrong in ur daigram u r makin a mistake dummy will not be at that place where u have drawn it. Dummy will be as i had shown it to u. in this case the answer is 1-2-4-6-7
and the longest time duration to complete any project is taken as the critical path
Do you have the solution of the above question???
no we were only given the question , we should work it out
answer is 21 months
yes i got the critical path right which would be A-C-F-H and the duration is 21 months
but we suppose to draw a table showing LFT, EST and the float
Activity I Duration I Start time I Finish Time I FLOAT I I ESTILST IEFT I LFT I 1-2 I 3 MonthsI 0 I 0 I 0 I 0 I 0 2-3 I 4 I 3 I 5 I 7 I 9 I 2 2-4 I 6 I 3 I 3 I 9 I 9 I 0 3-5 I 6 I 7 I 9 I 13 I 15 I 2 3-6 I 4 I 7 I 9 I 11 I 13 I 4 4-6 I 4 I 9 I 9 I 13 I 13 I 0 5-7 I 6 I 13 I 15 I 19 I 21 I 2 6-7 I 8 I 13 I 13 I 21 I 21 I 0
looks a bit confusing
lemme show u what i got
hey did u got it now or not in that check the above diagram and check the table
omg this helped so much the only problem now is showing the EST and LFT on the diagram
thank you so much for ur help i really appreciate it :)
its ok whr u r from
im from Jamaica u?
m from india. Actually i m new on this website
cool i'm new too just found out about it last week
i found it only yesterday. on damodaran's website

oh there is a part e to the question it says You were recently employed to the company as part of the project management team. Explain to your manager 5 possible benefits and 3 disadvantages to doing a critical path analysis.(15marks)
Advantages: It takes into consideration the longest time duration to complete the project that is, future is uncertain anything can happen while the project is going on so longest time is taken as the Projects life
Predicts the time required to complete the project.
Shows which activities are critical to maintaining the schedule and which are not.
Provides a graphical view of the project.
