Before you start adding state variables to a library object, I suggest that you first familiarize yourself with all of the existing states. One easy way to do this is to instantiate the object (e.g., Worker1) and then go to any expression field and type "Worker." and look at the list. In the case of Worker, there are over 100 states, functions, and properties built-in to the Worker object. Another way is to subclass the Worker, then go to the Definitions tab of the MyWorker object and you can see all of the built-in definitions by category: There is a pretty good chance that what you need is already there. But if not, use the same screen illustrated above and add whatever state (or property, event, ...) that you need. As far as referencing or assigning that custom state or a built-in state, it is done using ObjectName.StateName. For example if you added a state named TimeStartedMove to MyWorker, and you wanted to assign that value, you might assign MyWorker.TimeStartedMove to TimeNow. The tricky part, especially with more complex objects like Workers, is to determine exactly when/how to assign that value. Sometimes you can interact with the model itself to insert an Assign at the correct location (let's say in the Loaded Add-on Process). Or sometimes you might need to override the process logic in your custom object. The SimBits RecordDistanceTraveled and ElectricVehicle are examples to review.

Hello everyone, I am creating a new "customize" model and try to enable addon process, but I cannot find this option in the following list.

Hi all! I am simulating a facility with nearly 40 servers, each one starting with some entities in the input node at initialization and having a different capacity. Each server has a 0 input buffer capacity. My entity creation is currently set to having an interarrival time to be 4.33 weeks (1 month) with a random number of entities created. Currently, it runs 24/7 and does not care about the time, but I want to incorporate that. How can I make it so that the entities arrive once a month, let's say the first Monday, at 8am? How can I make it so the servers are only processing between 8am and 4pm Monday - Friday? The work schedule doesn't seem to work for me, but I could be doing it wrong, since I have a 0 input buffer, which I can't change as it's part of my routing logic for overflow. I would be happy with using timers or a process logic if someone can explain it to me. Ideally, the entities only arrive when it's during the working time, and the entities remaining after 4pm are just put on hold until 8am the next day. Thanks in advance!

Hello all, Can I use "print" command or similar process steps to print some information into console or a file for debugging? For example, in other programming environment, such as Javascript, I can insert ```console.log("xxxx");``` into program. Thank you!

Hello, You can go to the process tab in the model. Once in the process tab you can click on create process to create add on processes at the model level.

I have a multiple combiners into which a single worker provides entities. While the worker is at a specific combiner, I want to check if that combiner's output buffer is full. I'd prefer not to create a separate process for each combiner as I have dozens. How do I code the process so that it is generic and that 1 process can work for any combiner? I'm hoping this is an easy question. Sorry if it's obvious. Thanks for your help.

Happy new year! One thing that I noticed is that with this model, the server never have a state of "blocked". I increased the processing time of Server2 and added a status pie to Server1. The server 1 is either Processing or starved, but never blocked according to the pie. But it should be blocked part of the time since I increased the processing time of Server2 to force this. It looks like the Server1 only accepts a new item to process if the path between Server1 and Server2 has room for at least one more vehicle. So the time that it should be blocked is considered as part of the "Starved" instead. I tried to figure out why this happens without success. Anyone knows why this happens? I attach the model to the post. Thank you! Input Server1 not blocked.spfx

Hello everybody, I'm trying to make this work but I cant Type/Conteiner BinBig BinMed BinSmall Product1 1 1 - Product2 - 1 1 Product3 1 - 1 Product4 1 1 1 I want to make a node where these entities (Products and Bins) are convined in one batch, I try to use a process based in decitions and search.. the file is attached if you wanna take a look on it.. (the product have to be the parent) OptimoContenedores2.spfx

Hi, You won't need batch logics of the definition. Just the combiner is enough. I made a simplified version of your model. Producto1 requires 1 med and 1 big, while Producto 2 requires 1 small and 1 big. Pay attention to the process that I created at TransferNode1, you'll need to adjust it for the Producto3 and 4. Watch the Combiner Object aswell. Hope it helps. ExampleSimplified.spfx

Hello, I wouldn't use process for this one. There is a simple approach that you can use by modifying the SimBit "CombineMultipleEntityTypeOntoPallets". You'll need 3 ModelEntity Integer States to identify the quantity required of each Bin according to the Product. Let's say ModelEntity.Big, ModelEntity.Small and ModelEntity.Med. You can modify "Ops_Exited" step to assign those quantities. For the Producto1 for example, you'll have ModelEntity.Big == 1, ModelEntity.Med == 1 and ModelEntity.Small == 0. A little tip: you can use "Is.Producto1" (or "Is.Producto2", etc) on a decide step to identify which Producto is it. Now on the Combiner Object, follow the Simbit and change the BatchQuantity, to ModelEntity.Big, ModelEntity.Med and ModelEntity.Small. This should work.

Hi All, I want to do some calculations just before the simulation ends. I did it previous versions without problem but now on version 15.247, "on run ending" add-on process is not being executed.I tested it even on a new simple model file with source server sink. There is just two assign steps with breakpoints on the add-on process. But in model trace it doesnt show the add-process name, the state variable value is not assigned, and breakpoint is not reached. Anyone experiencing the same problem in this version? Is there a quick solution to this? Or do I have to install older version? Kind regards, Tolgahan

I used the "DashboardForScheduling" simbit as an example for this case. For the order that is using "FinishedGoodA" material, I want to change the sequence after the welding process is complete if both shape stations are not available. So, I created an alternative sequence table and referenced in the process logic I created. Whenever this happens, I get same type of error message. Do you think this is happening because the normal routing table is referenced at the source object?

I'm trying to do something similar to do this where an order has 4 different routes or paths it can go (My model currently doesn't have paths). I created 3 separate sequence tables and created a process logic depending on if a certain workstation is already processing an order/entity, to go through this sequence. For some reason, whenever it gets to the "set row" step, there is a table reference error mentioning "no entries found" if though in the process step, I specify which row to start the new sequence. What is the reason behind this error?

Hi I have an entity that is moved through the network via vehicles. The vehicle will drop of the entity at the first server which then gets processed through two servers. I would like to use the vehicle that dropped off the entity at the Input to the first server to be used to pick up the next entity at the output of the second server. Is there a way to save the exact Vehicle that was used and specify that as the Vehicle to use at the second pick up point? Hopefully to a global variable and not to the entity (in my actual model, the entity going in to Server 1 is not the next entity coming out of Server 2). At the moment I am using 'Reserve Closest' as the reservation method at Server 2. I know that is incorrect, but I'm not sure how to setup this up using the other methods. In the attached model, process works for the first entity, but does not for the second entity onwards. Due to other limitations in the model, I need to have the Vehicles to 'Remain in Place' during idle. Thanks in advance for the help. SpecificVehicle.spfx

Hello, I'm having strugles trying to configure the setup for the next process: some entities have a diferent processing time and setup time, before to enter to be processed in the workcenters, the workcenter have to be cleaned. I looked the simbit, "ServerWithSequenceDependenrSetup" but I'm confused with the configuration of the processing task. I dont know why we have two lines and o why only one have associeted the change-over matrix.

Hi all, I have a model with several servers, each with their own Changeover Matrix for cleaning between jobs. This is done by a Sequence Dependent Setup within the Servers Task Sequence steps. This is working fine when the Cleaning is either done 100% Automatic or 100% Manual with a Worker called as a Secondary resource. Some servers however require partial support from a Worker. For example a COMatrix of X mins needs to include 5 mins support from a Worker at the start and 10 mins support from a worker at the end of the Changeover period, with the middle X - 15 mins in the middle of the CO cleaning period (There are other more complex examples too where the operator will be required half way through the process too to empty the cleaning waste container). Is there a way of saving the COMatrix time, rather than running this delay, so that I can then build an add on process or add further task sequences to break the time into its Automated and Manual Components? Thanks in advance for any suggestions. J

This helped in some applications, especially use cases where multiple servers are in series and I need the operator to focus on the start or end of the process. Thanks! However, when servers are in parallel the operator tends to run back and forth between them. If I were to assign a higher priority to one line, the worker would focus on that line only. i.e. if he empties the que of parts in the input buffer of Server 1, he goes down to work on only 1 part at Server2 before going right back to Server1. Rather, I'd like for the operator to clear all parts in the que at Server1 before walking down to Server2 and vice-versa. I've tried doing this through process logic however I get stuck trying to evaluate which server the worker is supporting.

Model.spfx Hello, i am trying to stop the transport time for my entity. The process logic is as follows: hen the entity exits the Source output, the time stamp (MyVehicle.Stamp) is assigned with the value "TimeNow". When the transporter drops the entitys to the servers input the time is stopped (New Value = TimeNow- MyVehicle.Stamp) and simio calculates the transport costs. The error is attached. I get the same error, when i use MyModelEntity instead of MyVehicle. The model name is "Model311" in the attached project "Model". How or where do I have to set the stamp correctly? Thank you!

Thank you for the model! It took a long time to get the sprint release but now I can see it and it helps. Now I have another problem. I am trying to do a pick up at two different places and the drop off at one destination. There I want to have the transport costs split on the entity with the calculation TransportCostRate/TransportQty. The logic works like this: The transport from Source1 to Source2 (or BasicNode4) should be charged and assigned to ModelEntity.Cost. Then from Source2 to Server1 another calculation should be done, now with the increased transport quantity in dependency. But in BasicNode4 the process is not triggered by the ModelEntity, but by the Transporter. Is there any way that the process is triggered by the passenger? (the entity in the ridestation). The model is in the appendix. Best regards. Model_421.spfx

Thank you for the quick answer! But i get the same error type when using MyModelEntity instead of MyVehicle. Referenced definition type "MyModelEntity" does not match executing type "MyVehicle". In the Transport Logic of the Output@Source1 (Properties), i have the MyVehicle as a transporter. It seems like both of them are executing the add on process trigger...

Hi! I don't think you need to save those times stamps on MyVehicle. I would suggest you to use processes that triggers when the entity leaves the Output Buffer of the source and enters the Input Buffer of the server. To do that, create two process with the corresponding Triggering Event Name: Source1.OutputBuffer.Exited or Server1.InputBuffer.Entered, saving time stamps directly on the MyModelEntity.

Hello Gosia, I recommend using two State Variables to record the start and end times using the function TimeNow upon the Vehicle’s arrival to a Node. A Decide step is needed to check if the Current Node is different from the Destination Node and that is when values of the State Variables are assigned using the Assign step. The Processes will be set at the Vehicle’s Add-On Process Triggers On Entered Node and On Exiting Node. You can visit the SimBit section under the Support ribbon and check the SimBit titled “Record Distance Traveled” to see a similar example. Another approach is to create a custom Vehicle Class and use a Level State Variable instead of the two Real State Variables to collect information of the travel time. I suggest exploring the Level State Variable in the Help pages under the chapter titled “States”. I recommend checking the SimBit titled “Using Level States (from project Infection Propagation Using Continuous And Flow)” as well. Best Regards, Khaled

Hi, everyone I am developing a postgraduate project related to hospital OPD simulation. In one examination room, there will have a round 5 to 6 doctor using this room during the week. Now I am facing one problem, because every doctor process have difference processing time(function) as picture below(The number is doctor ID). Is there any method to set a difference process time during every shift in one server? or I have to create a process for this them?
