why does MSP prorates resorces in resource leveling?

hello,
can you explain?
what do you mean by "prorates"?

Hi, firstly thanks for your interest. I’ll try to explain with an example. Assume that an activity which has 5 days duration and also has 5 days slack. It has just 2 workers daily working as a resource it means 16 hours a day totally 80 hours for whole activity. If I want I can decrease the resources to 1 worker a day so the duration will increase to 10 days, finally it’s acceptable for my project because it doesn’t change my critical path or it doesn’t effect my cost the adjustment is done in available slacks.

I can do these without software and I couldn’t reach the same optimizations with MS project. MSP divide resources equally to activity duration and it just make splits if it’s necessary but it can’t increase the activity duration by allocating resources randomly although it has available slacks.

My e-mail is: ersinnamli@yahoo.com I can send you the sample projects

As far as I know, the only way to allocate resources not proportinaly is to use the Task usage view: you can enter the exact amount of work you want in every cell, that is every day or week according to the Timescale zoom.
In no way will MS Project easily split the resource allocation to take advantage of every hole in the resource agenda; it is possible to set up the resource leveling to split the remaining work and therefore split a long task to make space for short allocations (ie a 1/2 day meeting in the middle of a 2 week task), but it is much less clever than the corresponding feature in P3.

thanks for your help I’ll try these in p3 too.
