Project Intro Intermediate course
One unit resource for parallel tasks
Hi!
There is some possession time for working activity (possession for autobahn renovation for example. During working activity the road is closed for general use therefore the possession time worth some cost).
For example, daily cost of one eight-hours possession is £ 1000.
Some works use possession simultaneously, other tasks at different times. For few tasks the possession time not need.
How can I count total quantity of possessions which is needed
for project. And how it possible count the total cost all of possessions which are used.
For example:
If I use the possession like a working resource with some daily rate and assign it for two parallel tasks I get two possession for two parallel tasks - it is wrong because in fact I use one possession for two tasks. Besides that I get double cost for one possession time.
For upcoming training course dates see: Pricing & availability
RE: One unit resource for parallel tasks
Hello Igors,
Hope you enjoyed your Microsoft Project course with Best STL.
Thank you for your question regarding using one resource unit for parallel tasks. I notice from your description that you have two parallel tasks which are performed during the same possession period, therefore, when you assign the possession resource to these two tasks you must only allocate 0.5 of a unit to each task.
To be able to count the total quantity of possessions allocated you can filter the resource column for possession only. Add the 'Cost' column, then export the data to Excel where you can perform the usual calculated fields on the data.
I hope this resolves your question. If it has, please mark this question as resolved.
If you require further assistance, please reply to this post. Or perhaps you have another Microsoft Office question?
Have a great day.
Regards,

RE: One unit resource for parallel tasks
Hello Rodney,
The problem is that I don't know exactly when two or more tasks will be occuring in parallel and use common possession, because they are not linked (different technological operation from different tasks with different duration which happen in common crossings time), so that is not possible assign percents of unit resource for tasks originally.
In each day there may be different number of crossings between tasks with possession.
Possibly I can use possession as a resource with Std.Rate=0 then if count quantity of days with possession (I didn't know how! - Help me if possible), after that I could get total possession cost for project and use it as Cost resource.
Do you reccomend other way?
Thank You!
Regards,
Igor
RE: One unit resource for parallel tasks
Hello Igor,
It's a little difficult for me to answer your question without having your Project file in front of me. If you can attach a copy I would be most grateful. If you are not allowed to, then perhaps can you create a sample file with as much info as possible to help me resolve your issue. Come back to me if this option is feasible.
I look forward to your reply,
Have a great day.

RE: One unit resource for parallel tasks
Hello Igor,
I've had a chance to look at your file. I have made a few changes which I have highlighted on your file. I have attached the file for your attention and would like to know if these changes will work for you.
What I have done is remove all Possession resources from all tasks... then I created two tasks at the end of the project one for EE Possession and one for EN Possession. Each task covers the entire period which possesion is required for and the respective resource has been assigned using a standard rate of Euro 1000. I'm not sure if both tasks are required?
Will something like this work for you? Of course if this does what you want, you can move the task to a different position by dragging the ID number to the position you require. Just make sure you don't link it to any other task.
I hope this resolves your question. If it has, please mark this question as resolved.
If you require further assistance, please reply to this post. Or perhaps you have another Microsoft Office question?
Have a great day.

RE: One unit resource for parallel tasks
Thank you, Rodney!
Your example is useful, but it does not resolve all question.
1. Do I have to specify manualy constraint dates for start and finish (or duration) for "possession" tasks.
It's not very convenient because:
2. If I will change something in project there may appear "holes" in possesion (day or more inside main working circle when possession not need) or happen changing of starting or finishing possession. How can I see if this happen? Can I save assigned resources "possession" with 0 rate for this case?
3. And then I have to split "possession" task manualy in this case?

Igor
RE: One unit resource for parallel tasks
Hello Igor,
If you insert splits into a single task bar covering the entire possession period this will have the effect of moving the finish date forward which you don't want. Trying to fix this with contraints will not work.
I think that the best way to enter the possession task if there are gaps would be to separate each possesion period with an individual task each of which can be dealt with as you please. You could use 'Start No Earlier' constraints for each task. Try this and see if this will work for you.
I hope this resolves your question. If it has, please mark this question as resolved.
Have a great weekend.
