I need help on how i will determine the entire time it takes my simulation to run

Do you want real time or number of acts? What kind of sim is it?

real time.. Event-driven Sim

I initialized a timer variable in my world fields and increment it in worlds act method. my challenge is how to tell the time to stop after the whole simulation run completes.

If you want to put a condition on when the timer runs, then do it.

I have put this code but it's not stopping the simulation 
 private void stopSimulation(){
        if(grant_voteCount == world.NUMBER_OF_SERVER)
        { 
            Greenfoot.stop();
        }
    }

If this is for your FOLLOWER, CANDIDATE, LEADER scenario? If so, my thought was that using reset between runs is not the proper way to construct your project. Using the 'Run' button is fine, however. Then again, keeping the scenario running and using key or mouse input to begin a subsequent run would be even better. The simple way to know the difference between running and done is the content of lowServer (if "null", running; otherwise, done). This comparison along should allow you to remove the done field. This comparison can also be used in the world's started method to determine if a resetting of field values is in order.

I use reset to reset the world and used run to run the simulation again. any clue on how to code the running aspect will be appreciated. Thank you

The started method of the currently active world will automatically be called by greenfoot when the scenario goes into a running state.

I wrote a nextRun method that is taking of this. Thanks again

I am thinking of selecting a percentage of the servers that will assumed a failed state. I have not been able to think through on how to write the code to select lets say 2 from the whole servers. eg. if you select 0% as failed all server runs but if you select 10% then 10% of server will assume a failed state and will not participate in the simulation etc.

Maybe your world could use a method like the following: 
public void setActiveServers(int percent)
{
    java.util.List<Server> servers = (java.util.List<Server>)getObjects(Server.class);
    java.util.Collections.shuffle(servers);
    int nogos = servers.size()*percent/100;
    for (int i=0; i<servers.size(); i++) servers.get(i).setActive(i>=nogos);
}

please where will I call this method; in the worlds constructor or serverPopulation method?

Well, the servers need to already be in the world. What do you think?

i think this method will replace the serverpopulation
