New Software Release
Our latest release, Simio 11, is here!
I’m representing an empty container deposit, where the containers are stored in different blocks. Gate in trucks arrives to the deposit loaded with containers that have to be unloaded by cranes and stored in the container blocks. In addition, there are gate out trucks that arrive to the deposit to retrieve containers. In the model, the containers are represented as entities, so as the trucks. I use Stations to represent the blocks that store the containers. To understand the logic of container arrival, we have to notice that next to the Station there is a Transfer Node, and when a container enters the Node (through a Transfer step in a Process), is transferred to the Station. To understand the logic of container retrieval, we have to notice that there is a Combiner next to the Station, and when the truck enters the Parent Input Combiner Node, a Process is triggered that searches for the container in the corresponding Station, and then it to the Member Input Combiner. Given that there is one Station for one block of containers, a single Station is used for the arrival and the retrieval of containers. The problem that I have is that in certain occasions, when a container is going to enter a Station, an error occurs and Simio shows this message: “The entity location is in transition state “WaintingToTransferIntoStation” and a new transfer request is invalid”. I don’t understand why this happens, given that in the Node that triggers the Process that executes the Transfer, only a single container enters at a time. Any help is greatly appreciated! Release: 8.136.13569 Model is attached. https://dl.dropboxusercontent.com/u/41163946/ModelPlacillaNewV3.spfx
Hi, I'm simulating the system container in a container yard. My question is how I can make the interaction between the simulation and the database (SQL for example) container for the ordering of them in the database, this interaction should be done during the simulation. I need read and write in the DB along the simulation. thanks,
