Arena Advanced Transfer Conveyors Sequence

[@christianh2890]

Why should I not model this just with a basic process? What is the advantage of modeling this system using the Advanced Transfer modules?

The purpose of creating models is for understanding reality, and describing it. Sometimes your models will help you make decisions. Sometimes the key constraint of a system will be the material handling capabilities within the system. Taking into consideration the capacity and speed of the material handling may affect the response time of the system as a whole. Even more, if you have too many transporters they could actually reduce the response speed because they could block each other pass due to traffic. Whether you need to model the material handling or not will depend on the purpose of your simulation, and where the constraints are. If on the other hand there are no constraints on the way products move around the processes, or it's a negligible constraint, then for all practical purposes, you can just use a simpler model.

How i have to configurate a single convayour with space for 4 items per time who have to wait 2 operation to be done in order to advance by one object?

Giorgio, I've never done a model like that. However, conveyors come in 2 types. Accumulating and non accumulating. I believe (not sure) that accumulating allow the conveyor to keep working regardless of the stop in the last cell of the conveyor. Conversely, non-accumulating stops the complete conveyor if the last cell is stopped for any reason. I think if you seize a resource without exiting the conveyor, it may stop the conveyor, but not sure. You will have to try. Please let me know if you succeeded.

hello, why can't I calculate a different processing time between station in different distance of conveyor? I still got the same value even though tge distance of each station is different. Can you help me out?

i do not understand your statement

Hi. Thanks for sharing this video. Great! I have a question about ARENA: is it possible to use different times in the same resource? For example, I have 3 types of trucks arriving at the same time and they have to be weighed on the same scale. Truck A is weighed in 03 minutes, truck B is weighed in 05 minutes and truck C is weighed in 7 minutes. After weighing, they are released and the process is closed. So, how to build this model in ARENA? Could you help me? Thank you in advance.

Marcelo, You can add an attribute to the entities after creation with an ASSIGNMENT block. Let's say you name the attribute Myproctime. You can enter the word Myproctime in the process time value. In your case the entities are the trucks, and you would assign either 3, 5, or 7 to the value of the attribute. Make sure the units are expressed as minutes in the processing time parameters.

Sequences can also be used to modify attributes dynamically. Be dynamically I mean the attribute can change the value depending on the step it's at within the sequence.

@@dralbertomarquez Thank you very much. I was able to create the model. Hugs.
