Different processing times for a single label

I have 3 different labels going in to a processor. All 3 labels have different processing time for which, I have used values by case. Can anyone help me on how to divide one of the label processing times further more into percentage?

Hello @Kshitij Dhake,

You will need to edit the code to accomplish this. Can you attach your mode if you would like an example of how to accomplish this?

Processor time.fsm

Here is the model. For label "three" .I want the cycle time to be 70 s for 50% of the how many "three" enter the processor and 160 for 30 % of the how many "three" enter the processor

As Jeanette mentioned, you have to edit the code that determines the process time. In the example below I assumed that the missing 20% would be processed for the currently used value of 350s.

/**Custom Code*/
Object current = ownerobject(c);
Object item = param(1);

Variant value = item.Type;

double retValue = 1;

if (value == "one"){ retValue = 150;}
if (value == "two"){ retValue = 100;}
if (value == "three"){
    double rand = uniform(0, 100, getstream(current));
    if(rand < 50) {
        retValue = 70;
    }
    else if(rand < 80) {
        retValue = 160;
    }
    else {
        retValue = 350;
    }    
}

return retValue;

  1. (rand < 50) {
  2. retValue = 70;
  3. }
  4. else if(rand < 80) {
  5. retValue = 160;



does "rand<80" mean 20% ?

No - from the code you should be able to see that if rand is between 0 and 50 (out of 100) they get the value 70 - that's 50%. Then if rand is between 50 and 80 it will get 160 - that's 30%, not 20%. The final 20% get the value 350.

Those are cumulative values. "rand" is a random number between 0 and 100.

double rand = uniform(0, 100, getstream(current));

The first check asks if the number is smaller than 50 which will be true in 50% of the cases. 

if(rand < 50)

The next check, that only happens if the number is larger than 50, asks if the number is smaller than 80. This will be true in 30% of all cases (50 < rand < 80). 

else if(rand < 80)

Since there are only three cases, the last case doesn't need a condition, it simply takes all cases that haven't met a condition up to that point.
