Varying transporter capacity

Varying transporter capacity

We are having trouble with a concept within the model logic. We need a transporter to have a capacity that is determined by the item type that the transporter moves.

For example: A forklift must have a capacity of 1 if it is transporting item type 1. The same forklift must have a capacity of 40 if it is moving item type 2 (which has been batched on a queue).

Is there a way to do this without specifically making use of a combiner and a separator as this occurs often in the model?

Here I answered a similar question using Process Flow to control the transporter and, as part of the model, it carries different amounts of each itemtype.

Without the model to look at it is hard to give any specifics. Because the best way would depend on how the model functions. So this answer is going to be a general answer that may or may not point you in the right direction.

If the transporter is connected to the queue that is batching the 40 items, then in the OnEndCollecting trigger of the queue, I would set the transporter's maximum capacity using:

setvarnum(transporter,"maxcontent",40);

But I don't have a clue where you would set it back to 1 for type 1s because you didn't give any details where that happens. But you would need to do the same thing in a place that makes sense in your model.

Hi @Abubacker S,

This is an old thread, so your comment will probably not be seen by many users.

You could modify the "OnLoad" trigger of the transporter:

if(content(current) == 1){ 
	int MaxContent = -1;
	switch(getitemtype(item)){
		case 1:{ 
			MaxContent = 1;
			break; 
		}
		case 2:{
			MaxContent = 40;
			break;
		}
		default:{
			debug;
			break;
		}
	}
	setvarnum(current, "maxcontent", MaxContent);
}
