Thank you for the videos on precedence notation diagram! it is very helpful for students like me as it is very clear! But, may I ask what will you do in this situation. There are 2 activities e.g. activity A and B, and they have the same successor, activity M. A have FF relationship with M while B have normal FS relationship with M, but B to M (FS relationship) has a larger value of ES than A to M (FF relationship). Which value will you choose in this case?

@Engineer4Free

8 жыл бұрын

+Rita Indah Lestari In that case, the duration of A, B, and M are all significant too. For the A-M relationship, you can first find the EF of M, then subtract the duration to find the ES of M. Then you need to check the B-M relationship. You can first find the ES of M based on E. You would then compare the ES of M given by A and then also as given by B, and chose the larger value. You must chose the larger value in the forward pass because in order to satisfy both predecessors. As you can see, the logic AND the durations of all activities in question would affect the outcome. Hope that helps!

PERFECT !

This is easier that the question the doctor gave to us in the assignment -_-

Is the Gantt chart plotted for activity E correct? It says E can start 3 days after C finishes with a duration of 1. So if C finishes on day 3, E should be be plotted on day 4? Right?

Thanks for the great tutorial! In this diagram, we have 3 paths in total. They are (i) A-B-D-G-H, (ii) A-C-E-G-H, (iii) A-C-F-H If there were no lags, we could just add up all the durations of all activities in a single path to get the critical path (project duration). Now, is there any way to get the critical path by adding up the duration of the activities and ± lag? Kind regards.

@tarashankarsharma3372

4 жыл бұрын

No, it is not that if there is no lag we simply add all the activities to get critical path and duration of project. We must follow the pattern of network diagram and work accordingly with it to get critical path and total project duration. And type of relationship given to activity must be taken in consideration.

It becomes something else to move from the gantt chart to the activity table. My lecturer just frustrated us with such as you turn to see weird pertchart...

I'm still struggling with the backwards pass!! We saw one small example in a copy, no actual drawn out example and we have to do a 32 length activity with FS and SS events.

@Engineer4Free

Hey Sean, I recommend taking a step back then. Definitely watch videos 4-9 here: engineer4free.com/project-management and if you have time (like 2 hours or so) then I recommend just watching everything up to the video that we're commenting on (which is video 22). Going through them all will fill you in with bits of insight here and there and will just get you some more practice to get comfortable with the topic. Cheers let me know how your progress goes!

working backward, is there a method of reading the gant chart to get the values or a formula to quickly and with less effort get them values?

@Engineer4Free

5 жыл бұрын

You can only read the ES and EF values off the Gantt chart. The numbers that each activity on the Gantt chart start and stop on are the ES and EF values. You could use them to populate the network diagram and skip the forward pass, but you will still need to do the backward pass. I recommend drawing the gantt chart and network diagram, and doing the actual forward pass, and then quickly checking the ES/EF values against the gantt chart to make sure that it looks like you have no errors. That's more valuable to you then using then using the Gantt chart to skip a step.

Sir, if G depends on D but on the pert diagram G starts before D finishes so it doesn't depend on D.

good presentation

but why is it that the ES of each first activity in a CPM is a 0?

@Engineer4Free

7 жыл бұрын

Watch video #1 here: engineer4free.com/project-management . The 0 comes from the way that I draw Gantt charts, and gets directly translated into the way that I draw network diagrams. In that video you will notice that 0 represents the beginning of day one. 1 represents the end of day one and also the beginning of day two. 2 represents the end of day two, but also the beginning of day three, and so on. In that video, you can see this pattern, because activity A ends at 2 which is clearly the end of the second day, but activity B starts also at 2, but is the beginning of the third day. In a network diagram, the EF of A would be 2, and the ES of B would be 2. The same logic applies to why activity A stars at 0, not 1. Does that help?

Hi, do you also have examples of network diagrams with subsequent tasks having 2 or more of the same predecessors?

What do you do when you have 2 dependencies on one activity, one has a lag and the other doesn't. Any ideas?

@Engineer4Free

6 жыл бұрын

On the forward pass, consider what the ES of the successor would be from each predecessor independently, factoring in lag if applicable and then take the largest ES of the scenarios as actual ES of the successor. For the backward pass, assess the LF of a predecessor for each of it's successors independently, taking any lag into consideration and then take the smallest LF of the scenarios as actual LF of the predecessor. You can find the ES or LF of one activity caused by a related activity whether or not lag is present, so if some relationships have lag and others don't, it won't affect the way that we approach the problem. Does that clear it up?

Thank you for the response.

Hi I not clear on how critical path is determined manually from a network diagram with Lags/Leads. Without lags/Leads we understand the critical path is the longest path in the network diagram and each task/activity on the critical path has its Start of Activity (LS-ES=0) and Finish of Activity (LF-EF=0) in short no slack at all. In addition, we can also add the individual duration of activities in the critical path to get the EF of the project. Now how do we use this same principle on a network diagram with lags/leads to determine the critical path? Lets take your example above - based on this diagram you have three paths (i) A-B-D-G-H, (ii) A-C-E-G-H, (iii) A-C-F-H. Out of these three the only path that have the Start of Activity (LS-ES=0) and Finish of Activity (LF-EF=0) is A-B-D-G-H and if we add the duration of these activities it gives a total of 16 but the EF of the last activity shows 14...so this shows we cannot apply the same approach to determine the critical path as we do when there is no lags/leads. Can you please let me know how the critical path is determined manually taking your example above. Your input much appreciated.

Hi, sorry for any confusion brought about by the naming of each style of diagram. There are two types of network diagrams: Activity on Node (AON) and Activity on Arrow (AOA). In these videos I usually refer to AON as PDM, and AOA as CPM. That's local lingo for me that I originally learned, but you are actually better to use AON and AOA, it's more clear.
