I have a table that allowcate 5 gates will have different entity will launch in specify date and time. How can i do it ? We are designing a airport simulate aircraft departure its gate.

We are simulating the aircraft will leaving the gate according to our real data history. How can i import the table in simio and let the aircraft leave the gate accouring to the time and date? Also some gate will have more than one different time and date that aircraft will departure the gate. How can i do it as well?

Hi everyone, I am trying to model entities moving from 10 origins (sources) to 10 destinations (sinks). The entities are simultaneously created according to a certain mix (Entity1 (85%), Entity2 (10%), and Entity3 (5%). However, the number of entities created per event is according to a certain distribution. There is an OD-matrix that captures the number of entities moving from origin to a specific destination. Let's say there are 10 destinations, than the destinations of the Entities are determined according to the OD-matrix: Entity1 and Entity2 can move to any of of the sinks. Entity3 can only move to one specific sink. One solution I came up with was to add weights to Connectors and assign destinations using TransferNodes, but I think that this is very inefficient. I then started to work with DataTables, but I cannot figure out how to probabilistically assign the destinations of the entities. My question is: how to model the probabilistic destination assignment of Entities using DataTables in such a way that it is relatively easy and flexible to add or remove Sources/Sinks? I have added the model for you to see, I hope that you can help me! Many thanks in advance Simple_OD_creation.spfx

Hey Simio insiders, I have been working on a model with workers. The workers transport goods over a facility, from one server to another. They seem to work perfectly until about 2 hours into the simulation. I have been looking into the the 'watch' properties, and it appears that the worker is waiting for something. This happens eventough i do not have a wait process in place. It waits at a server which it is about to drop an entity. The server input buffer is infinity, since i thought it might have caused the problem. Do any of you know why my worker is waiting?

Ok, I think that I sort it out. I am not very confident of what I do but I think that it works now: I changed the Vehivle "Routing Logic". Idle action: Go to home AND I changed for every server, secondary resources: Earlier it did not work because the vehicle was stuck at the sink waiting for an entity to be available at the source. The idle action for the vehicle was to "Park at home"..

I am doing a Final Year Project with Simio. Our topic is discusing the taxiway routing problem to enhance aircraft congustion in the taxiway. Our group are the new to use simio, when we want to do some simulation on the taxiway, we dont know how to increse the same distence between different space of the entity(ie. airplane) in the path(ie. Taxiway). Also how to make the entity stay in the path while waiting the privious plane leave the runway? We would like to do the silulation like this video https://www.simio.com/applications/airports-and-airlines-simulation-software/ 1:08-1:30 Any one can help us?

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

Hello, I'm working on an emergency department (ED) model where I'm using both nurses and doctors as resources. At the ED, there is a 4:1 Patient to Nurse ratio, meaning that on average, a nurse takes care of 4 patients at the same time. When I was thinking about how to implement this logic on Simio, I looked at this option on the Seize step under Advanced options (you can see it on the picture I attached). I set the Units per Object to 0.25 - because I thought that every time a patient seizes a nurse, it will take out 0.25 out of 1 unit of capacity, instead of taking the whole 1, allowing for 3 other patients to seize her before she is completely busy. However, this doesn't work, because I ran a model trace as I ran the model and the server is ignoring the seize because the "Units per object" is set to 0 (which is not, it's set to 0.25) - the exact model trace comment is: "Ignoring resource release of type Specific 'Nurse'. The required capacity units per object '0' is not a positive quantity.". Therefore, the model ignores the resource seize and processes the entity without the resource. Is this because this property field only works with integers? I thought of a work around by just multiplying my number of nurses by 4 to account for that, but that's not optimal. Would there be any other way of achieving this? Thank you very much for the help!

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 River, I downloaded your files. The Gate512 was missing. I removed the information in the "30 Departure.xlxs" file that I can run the model ;-). Generally I understood how it works. Answer to your first question: I think you mean these two ways, right? From the left and from the right. In this case I saw that you used the "Routing Logic" in like all Transfernodes. The Outbound Link Rule is "Shortest Path" and you set the "Node Name" to "Input@Takeoff" Simio is using everytime the shortest link path now. Like in the screenshot below: In my opinion it would be better to set the destination once after the Entity got created in the Source for example :-). There are different ways to do that. In your model I removed all Routing Logic in the Transfernodes and used the Routing Logic only in the Output-TransferNodes of the Sources. In Simio you need only to use one time a SetNode-Step or a Routing-Logic to set the destination of an Entitiy and Simio will follow the paths or travel in the FreeSpace. You can use for example a NodeList with 2 different destinations and this Routing-Logic: With the "Selection Goal" Random Simio will randomly choose the destination from the NodeList. I uploaded you your model with the changes as an example: Problem on the taxiway version 17A.zip What did I changed? 1) I removed the Routing Logic in all TransferNodes. 2) I added new Routing Logic to the TransferNodes of the Output-Node of the Sources. 3) I added a NodeList with 2 new Nodes. 4) In the two new Nodes I used a Nodes-Entered-Process and a Transfer-Step to transfer the Entity to the Input of the Sink. Answer to your second question: You can change the destination of an Entity any time. In the Path (Link) you have a function called "NumberTravelors" for example to get the number of travelors currently on this path. So you can use a Expression like "Path123.NumberTravelors < 2". This can be used to decide if a way is full allready that the other way get selected. Or you can use a Integer-State and count up and down. I would use a Node-Entered-Process in the last possible node with a Decide-Step and two SetNode-Step in this case :-). I hope my answer will help you. When you have any other question, you are welcome! Best regards Pascal

Hello, I'm new to both the forum and the world of simio in general. I am trying to simulate how much the maximum buffer could be in 2 points of my process which are defined by the Buffer_ST1 and Buffer_ST2 servers. My problem is that I would like the Buffer_ST2 server based on a condition that would be every time an entity passes on Input @ Buffer_ST1, the Buffer_ST2 server releases only one processed entity and not all those inside the server as it happens now, I hope for being clear and thank you in advance. I put the model in the attachment Buffer varianti trazioni V2.spfx

Hi, I'm trying to keep track of the time traveled of each vehicle in my system. I'm attaching a basic file with the current model. Aly help will be highly appreciated. Nw_Working_All_Logic.spfx

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

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 Vinicius, thank you for you help but I still having problems with the model. I can understand the logic behind of the SimBit "CombineMultipleEntityTypeOntoPallets" but I have some doubts. I change the model adding a combiner, I creted a intergrer model entity state to identify the quantity of containers, and I have a real state to identify the container but I dont know how change the batch logic of the container to each product. In the definitios tab you can see the batch logics. I hope you can help me Best regards. OptimoContenedores3.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, Usually what I do in cases that I want to check capacity before sending is create a "dummy" Resource. This way I seize its capacity before sending the entity forward. If it has no capacity for a given entity, the entity will just wait until it has capacity.

Hello, please I need your help. I have a combiner in my model called Revisar_pedido, which fulfills its function without any problem until, at one point, an entity enters (Pedido_PU.597) and gets stuck inside it and I can't understand why it doesn't come out. I already checked the functions, processes and states and nothing seems wrong. I attach my model for better understanding. Beforehand thank you very much. 06.11.spfx

Hi Fabian, I see two (or more) possible alternatives for solving this. Assuming that the box only receives one type of entity you can: 1. Create a state variable (for example st_CurrentBoxType) and every time an entity enters the combiner you assign the entity type to this state variable. This way, one the box is completed and exits the combiner you will be able to assign it the st_CurrentBoxType. 2. The other way is to execute a search step once the box is full. You can use "ModelEntity.BatchMembers.FirstItem" as match condition to locate the first batched entity, then in the found branch use an assing step to assign the ProdType from the found entity I'm sure there are a lot of ways of doing that... hope this helps saludos

Hello, I am working on a Demo Model and I would like to use the Console feature. The Console has a lot of "pros" because you can decide whether to display/hide KPIs, place buttons...However, it has a couple of "cons" that make its usage less friendly: Console Size cannot be pre-defined. Every time that the Open Console is clicked, the console will be opened in a different place and with a small size, which forces to manually move it and resize it so that everything can be seen more clearly. Gridlines cannot be hidden. I have tried to disable them in the section of view - gridlines, but it has not been possible. Any of you know if these two features actually exist and it's me that I do not know them? Attached there are a couple of screenshots of what I mention and the model itself (DemoModel should be run and right click open console). ConsoleIssue.spfx

Hi there, I'm very much a novice, but currently leveraging the logic in VisitAllServersInAnyOrder simbit to ensure an entity visits an entity is never reworked more than once. I've updated the model entity with required state variables and created a "MyServer" to create the "HasEntityVisited" etc etc. I'm using the "Candidate.MyServer.HasEntityVisited==False" logic for the selection condition in the output node routing logic. However, whenever I run the model I get the error message "Referenced definition type "MyServer" does not match executing type "BasicNode". I've gone over and over the various elements and compared to the working simbit, but can't identify the issue. Any help would be greatly appreciated. Thanks in advance. Garrett

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

I want to build a simple repository model,as the Picture below. And there are two Funktions, that i donn't know, how to implement. The first Problem is: I hope that several products with different total amount can be generated in sequence one by one. For Example, there are 50 Product A, 40 Product B and 30 Product C at Source WE. They schould be generated in sequence. First 50 Product A,1,2,3...50 one by one generated. Then 40B, generated one by one and finally C. At present, I can only achieve one-time generation of all A, then all B and All C. The second Problem ist: there are may be 10 Vehicles in the System. I want to record the total time of the car loaded and empty travel time, and the corresponding percentage of these two items. I would be very very grateful if you could help. I'm really in a hurry and hope to get your help.
