SendToClosestQueue.fsm

I made this demonstration model that shows how you can use a Custom Code activity to find the queue that's closest to the operator and set that queue as the token.destination. I used Vec3 and found the vector from the origin to each queue, and the vector from the origin to the operator, and subtracted them. I then found the minimum distance vector, and set the corresponding queue as the destination queue.

There's probably a cleaner, more robust way to do this using for loops or tables, but this will give you an idea of some of the principles needed to make your model.

Here's the custom code:

/**Custom Code*/
Object current = param(1);
treenode activity = param(2);
Token token = param(3);
treenode processFlow = ownerobject(activity);

Object operator = Model.find("Operator1");
Object queue1 = Model.find("Queue1");
Object queue2 = Model.find("Queue2");
Object queue3 = Model.find("Queue3");
Array Queues = [queue1, queue2, queue3];// Array of all queues (1-3)

Vec2 Op = Vec2(operator.location.x, operator.location.y);//vector from Origin to operator
Vec2 Q1 = Vec2(queue1.location.x, queue1.location.y);//vectors from Origin to each queue
Vec2 Q2 = Vec2(queue2.location.x, queue2.location.y);
Vec2 Q3 = Vec2(queue3.location.x, queue3.location.y);

Vec2 dif1 = Q1 - Op;// Subtract operator vector from each queue vector
Vec2 dif2 = Q2 - Op;
Vec2 dif3 = Q3 - Op;

Array distances = [dif1.magnitude, dif2.magnitude, dif3.magnitude]; // Array of all distances (1-3)
double minvalue = Math.min(distances);// shortest distance wins

int index = findmatch(distances.length, distances[count] == minvalue); // use shortest distance to get corresponding queue

Object destQueue = Queues[index];// Destination queue

token.destination = destQueue;

Here's the layout of the model:
