I am trying to create a model in which 4 different entities are generated randomly. Once the entity is generated, then I want to be able to control the probability that the generated event occurs. Is something like this possible, how can it be done?

Could you possibly use random number generation ('rand')? Say something has a 25% probability of event 'X' happening, 35% for 'Y' and 40% for 'Z'. You could say:

 val = rand;
 if(val<=.25)                    %  25% chance
     % event X
 else if(val>.25 & val <=.6)     % .6-.25 = .35 for the 35%
         % event Y
     else if(val>.6)             % 40% chance
             % event Z
         end
     end
 end

Would I enter this into the entity block for the Matlab function? Would it be in entity generation or event actions? Also, how do you generate a graph for when utilization of resources using blocks from version 5.2. Thanks!
