hai,
I want to make a simulation model of an Automated Vehicle Storage and Retrieval System (AVS/RS) in Simio. How can I make it? does anyone have any idea. I can give you the specifications of the system.

building of the primary model is the main problem, since the system is a 3 dimensional one with storage racks in different levels and automated vehicles running between them.

You may need to use Station elements to stand for each storage bin and use process logic to do the storage logic

Here's one: https://onedrive.live.com/redir?resid=A68E052E2311B661!1363&authkey=!AFFBM4T1_qAH1YQ&ithint=video%2cmp4
But sit down first because it may make you dizzy. :)

thanks. it is a completed working model. I am looking for vedios similar to our lab tutorials which explains how a model can be built. I just want to get that approach/ idea for the AVS/RS model making

You will probably have to start with specification of what is the funcionality and aim of the simulation.

I can imagine, that different approaches will be used if you are concerned with storage capacity or if you want to simulate utilization of vehicles.
Other differences apply if you want to have random (chaotic) storage or will have some specific demand for storing different types of pallets.

The main aim is to find out the resource utilisation ie. the vehicle and lift utilisation under different demand rate rate( storage or retrieval rate). demand rate is the dynamic one.
random storage policy, first come first serve are some of the assumptions and the configuration is "tier captive ".
The retrieval transaction demand to the system follows a poisson distribution with parameter "lamda". Lift and vehicle service time follows a uniform distribution.

station element is used to stand for storage bin. in actual case vehicles are used to move entities to the bin, how can this logic be incorporated in simio. the dimensions of bins are known and it is intended to find the distance travelled by the vehicle.
