Hi all,   Having a bit of frustration with models. I have quite a few assembly stations in the demo model that I am building. Somehow these assembly stations keep failing, all of the items required to complete the assembly arrive as required at the assembly station but then the process simply does not move any further than that. Any ideas as to what the problem might be?   Also   I want to create a pull based start point. Usually to do this I simply program the item creation to have the same time as the duration of the first process.   This time however I want an item to "come out of a storage bin" at the exact time that another item finishes a process so that the two get to an assembly station at the same time. Can this be done?

Most likely the problem is the that the queue at the assembly process is full, or the process is receiving an object that is not part of an assembly or being assembled. To fix this issue, first check the assembly settings of the process and make sure it is setup, then enable the behavior on the connection line feeding the assembly process to have "Block if next process is busy". You also need to enable - Ignore active object at destination, - Enable Based on assembly option Concerning the second item, you need to use events to enable the release that is triggered when you need the objects to leave the storage, then use the controlled event release to allow the different parts be released from their locations. Using timing to implement this behavior will not work properly. Please check the controlled event release tutorial in the tutorial videos. If you are still having problem with the model, please upload it to the forum so we can have a better idea of the implementation. Based on that, we will either send you detailed instructions on how to correct it, or setup a quick web conference to help you through. Hosni


The control from one process to the next can also be implemented using the connection line behavior setting under the customization section. Here you can set the line to "block if next destination is busy" this will implement a pull system. 

Based on the models assembly flow you can simply segment the buffer with the proper component definition, that will also work. Brent is sending over an updated model with the change to buffer segmentation. He also has some questions on the oven capacity as defined in the model, specifically "What is the capacity of the oven?" i.e. how many parts can be processed simultaneously.
