Send flowitems to pickup points by item.type

ssrdh — Wed, 15 Apr 2020 23:58:14 GMT

Hi!

I am relatively new to AGV in flexsim. I am working on a model where I have multiple sources with different item.type. In the attached model, I have 2 sources and I have 2 pickup points. Is there a way to use just single source and send item to pickup points by item.type.

Thanks,

For your first question, set up your arrival schedule like this:

Notice the 'Type' label is now part of the schedule and the sequence of arrivals is in order by time.

For your second question you would have to change the model layout I bit I think. Rather than sending from the Source directly to the Sinks, send to a two queues that are attached to your two pick up points. Like this:

THen set your Source's Send to Port parameter to:

item.Type

And that will send your items to a port with the same number as your Type label (1 and 2).

hey @Regan Blackett,

I implemented the method you explained above. I am able to send item by type to the different queues. However, the queues are not sending flow items to the pickup points. I have enabled "use transport" for the queue. Am I missing something here?

@Aditya S2
Are you saying you want the queues to move the items into the Control Points, and then have the AGV's load them there instead of the AGV's going to the control points and then loading directly from the queue?

@Braydn T

Either method works for me. In the model I am building I have items sent to the queues by item.Type.

I want the AGV to load those items either from the queue or the control point. But currently the items are on the queue and not being picked up by the AGVs. How do I make sure the AGVs do pickup items from the queue or the control point? Thanks

@Aditya S2 Could you upload your model so we can debug it directly? IF they are connected by port connections correctly, or being referenced correctly in PF, there should not be an issue.

@Aditya S2,

It looks like the connections between Queue1 and Queue2 were made to the wrong control point. The AGV template uses "NextLookForWork" points to determine whether or not there are items to be loaded at a given station. I re-arranged the connections so that the blue connectors between the control point and the queues are connected to a control point that is in the "NextLookForWork" loop.

The model seems to be working now. Feel free to comment back with an update if you were looking for something different.

How do we designate items only from Queue1 to be on the left control point and only items from queue 2 be on the right cp? I pretty much need to assign a control point to a queue and only that queue. I have 8 queues and 8 CP's(placed directly in front) and want Queue 3 to go to CP3 and then queue 6 to only go to CP6
