Thanzeel66 Posted April 22, 2016 Share Posted April 22, 2016 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. Link to comment Share on other sites More sharing options...
Thanzeel66 Posted April 23, 2016 Author Share Posted April 23, 2016 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.

jzhou Posted April 23, 2016 Share Posted April 23, 2016 You may need to use Station elements to stand for each storage bin and use process logic to do the storage logic Link to comment Share on other sites More sharing options...
Thanzeel66 Posted April 23, 2016 Author Share Posted April 23, 2016 Is there any special care to be taken for the allocation of vehicles and lifts Link to comment Share on other sites More sharing options...
Thanzeel66 Posted April 24, 2016 Author Share Posted April 24, 2016 Is there any sample vedio showing AVS/RS or similar model building available? Link to comment Share on other sites More sharing options...
dsturrock Posted April 25, 2016 Share Posted April 25, 2016 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. Link to comment Share on other sites More sharing options...
Thanzeel66 Posted April 26, 2016 Author Share Posted April 26, 2016 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 Link to comment Share on other sites More sharing options...
tulach Posted April 26, 2016 Share Posted April 26, 2016 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.

Thanzeel66 Posted April 26, 2016 Author Share Posted April 26, 2016 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.

Thanzeel66 Posted May 3, 2016 Author Share Posted May 3, 2016 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.
