Anylogic: While(true) Function for Wait Block-CodePudding

Hi I'm trying to simulate an Assembly Station, therefor i would like to coordinate the release of my material with a wait block. My process includes following steps:

3 Different Paths: Source --> Seize Transporter ---> Move ---> Wait Block ---> release ---> Assembler (See screenshot)

Model

I would like to release my Agent in their wait blocks when all agents arrived in their Blocks. The Problem that i'm facing right now is, that all 3 agents arrive on different times. For example Agent one is arriving After 10 min in the waitblock1, Agent 2 and 3 After 5min in the block 2 and 3. So Agent1 should check if the other agents arrived in their Blocks and then be released. Also Agent 2 and 3 should act the same, so that all 3 agents are released at the same time.

Therefor i added for example in the wait block 1 a while(true) loop to proof if there is an Agent in the wait block 2 and 3 and then release the Agent in the current wait block. From my logic i would add this code also to the wait block 2 and 3 so that finally all agents will be released

The code is in the "on Enter" Field of the "waitblock":

while(true) {if(wait1.size()>0 &wait2.size()>0)wait.free(agent);}

If I run the Model i get follwing error code: "Unreachable Code". To be honest i'm new in using Java but i would say the code should be right? Maybe my Methode to comparise the wait Blocks and release the agents is wrong. Anyway i would be glade if someone could help :)

thanks in Advance

Put the the condition into the while() or add a break statement

while(wait1.size()>0 &wait2.size()>0)
   ; 
wait.free(agent);

Otherwise the loop will never end and code after be unreachable

CodePudding user response：

this is not how you do it, you can't use while(true) unless you run that in an independent thread

Also the and operator is written && and not &

so on the on enter of every block make a function, and on that function you will do the following more or less:

if(wait1.size()>0 && wait2.size()>0 && wait.size()>0){
     wait.free(wait.get(0));
     wait1.free(wait1.get(0));
     wait2.free(wait2.get(0));
}
