Hi, After 2 years I think if I payed more attention to my operating system lectures I wouldn't be asking this question. I am working on Accident/Breakdown Events Manager for a transportation company. I just want to recall that equation for calculating process scheduling priorites. Hope you guys will help me mhadi

What OS are you running on? On Windows it's pretty simple, but on Unix it's a complete PITA (and, of course, each version of Unix has its own procedures).

Hi,
Thanks for replying. This not a OS scenario I am applying Process sceduling to Crisis management :)

There are mainly two categories of events happening in transportation.
1. Accidents
2. Breakdowns

Accidents have higher inital priority(say 100) than Breakdowns(50)
Once an event is reported its prority start getting higher until the apropriate services reach the scene. As soon as they reach the scence cannot prempted until it is solved.

Now you can imagine it as follows

we have got multiple processors(Services) and multiple processes(Accidents or breakdown). Once process is started it is not given processor to start its excution(services take time to reach the scene). Untill the process does not start its execution its priority will be calculated say after each minute. Once the services reach the scene its priority goes down but does not leave the scene until it is completly solved.

Hope you can understand my point clearly. If also needs some explainiation please do ask.
