The question refers to workload management from different perspectives: organisational, individual, operational demand. I'm just interesting in different viewpoints on this question
More on workload management: http://books.google.se/books?id=Mm3Oj6CCr5gC&pg=PA792&dq=workload+management+railway*&hl=sv&sa=X&ei=MQ-GVKf8DcT4ywOInID4Dg&ved=0CDwQ6AEwAw#v=onepage&q=workload%20management%20railway*&f=false
There are, as I mentioned, more than ten books on the issue, and I am sure that you will find such things in the (perhaps) best journal on the market:
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit - http://pif.sagepub.com
Thank you for your comment and relevant sources of information!
Yes I've already browsed the journal papers and books, and have written a literature review about it. Maybe there have been a few recent research in this area that I missed. So, any additional information and opinions are really appreciated.
Thank you for your reply and I will look through all the links you sent.
