Hi, there is a simple approach you can use. Use Connectors between the queue server and the desks. At Buffer Logic of the Desks, change the Input Buffer Capacity to 0. Create a List with the Input nodes of the seven Desks. On the Output of the queue server change Entity Destination Type to Select From List and the goal to Smallest Value. Keep the default expression. It should work fine.

A basic photo eye object that can be used with conveyor belts. Photo eye is based on a transfer node object. It collects statistics on time in blocked state, cleared state and throughput. Transfer nodes on entered and on exited add on processes can be used as on blocking and on clearing add on processes. Photo eye has properties to define the delays for on blocked and on cleared. Photo eye will wait to complete on blocked delay to execute on blocked add on process. Similarly, photo eye will wait to complete on cleared delay to execute on cleared add on process.

Hi all, I am building a simulation of a system with multiple separators which MemberOutput nodes two different routing policies can occur: 1. Standard Policy In the 'Standard Policy', each separator has its dedicated transporter assigned to it and entities arriving at the MemberOutputNode can only select the defined transporter. To this end, a DataTable has been constructed. 2. Power Hour policy In the 'Power Hour Policy', operations are shifted into a higher gear. We select a maximum number of three nearest transporters whose ride request is 0 and include them in the DataTable which specifies the Transporter Selection. Entities arriving at the MemberOutputNode can now request rides from any transporter in the DataTable. I tried to reference to a DataTable called 'TransporterSelection.EPT' in the Transport Logic of each MemberOutput Node. Each value in the EPT column is cross-referencing to a DataTable in which I try to assign the MemberInput Nodes as a Node Reference State Variable of the Transporter (EPT). Is there any way to dynamically assign more (or less for that matter) Transporters to a TransferNode? Hope that anyone knows how to do this! Cheers, Toon

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

I am running some experiments on my model. I have a couple of transporters delivering fuel to three server nodes. I am trying to have the model maintain adequate fuel levels at the servers despite disruptions. Currently I have 4 responses (1 for each server and 1 that sums their fuel levels) and the responses are based on the expressions: Input@LineCompany1.AssociatedStationLoad Input@LineCompany2.AssociatedStationLoad Input@LineCompany3.AssociatedStationLoad and FuelTotal: Input@LineCompany1.AssociatedStationLoad + Input@LineCompany2.AssociatedStationLoad + Input@LineCompany3.AssociatedStationLoad I get responses as such: with the ACoFuel, BCoFuel, and CCoFuel ranging between 0 and 2 and FuelTotal ranging from 0 to 3. The capacities of these server nodes are 0 to 12 and everything is handled in integers. I am confused on how these responses are being calculated and any light that could be shed on this would be greatly appreciated.

I am trying to make a routing decision based on the Candidate node's routerequestqueue's summation of the entities user-defined property. If there are different types of entities with ex. different priority levels. I would like the routing process to choose the transfernode which has the smallest total sum of it's entities priority level. the transfernode that needs to be chosen also has a routing group attached to its entity destination type rule where its final machine has 0 buffer and due to a blocked destination rule, there will be a queue build up at the transfernode that needs to be chosen. I have thought about using a state variable for each node and using add-on process each time a unit enters and leaves a node but because the main model has many multiple nodes the node's entity priority sum has to be able to be accessed through the candidate.transfernode._________________. For example during the routing step in the process section, I have candidate.transfernode.destinationroutinggroupname.routerequestqueue which gives me the node's number of units waiting, but i need to be able to access the candidate nodes summed queued property. Is there either a way to directly access this information, have looked at the expressions and having a hard time finding something. failed attempt: candidate.transfernode.destinationroutinggroupname.routerequestqueue.population.defaultentity.priority.summation or is there a way to use the add-on process where i am adding/subtracting the priority levels, but somehow attach it to the candidate.transfernode's property Hopefully this makes sense. If you look at the file, please ignore the upper half and focus on the transfer nodes maintransfer, transfernode1 and transfernode1_1. maintransfer has an entered add-onprocess which is the subject of this question. the route process and it's selection expression is what I'm trying to adjust but find a way to express the candidate transfernodes of transfernode1 and transfernode1_1 (which are part of the XferRouting group). I'd like to choose and compare the total summed priority level of each node's queue. Simple_Routing.spfx

I have 2 transports delivering entities to 3 servers. What should be happening is that Transport 1 loads entities to capacity (12) then moves to Server 1 and delivers all of the entities (12). Transport 2 should load 12 entities and deliver all 12 to Server 2. Transport 1 returns to Home Node and loads 12 more entities for delivery to Server 3... and so on. However, what is happening is that both Transports are loading 12 entities then moving to Server 1 and delivering 4 entities each, then on to Server 2 and repeat and so on. I have removed and added servers to confirm that for some reason the Transports are delivering 1/#ofServers of their total capacity, conducting all of their deliveries and then returning to home once empty. I have limited the timepath to each Server to only allow 1 Transport at a time, but then Transport 2 just waits at the Home Node until Transport 1 is on its way to Server 2. Then it moves to Server 1 and just ends up one node behind Transport 1 at all times. The dispatch logic: (Server1.InputBuffer.Contents.NumberWaiting <= 12)||(Server2.InputBuffer.Contents.NumberWaiting <= 12)||(Server3.InputBuffer.Contents.NumberWaiting <= 12); set at Smallest Value for Selection Goal; Selects from a List of all Server Nodes.

In fact, even if I use just two simple nodes without any steps and other objects, it is not possible to create a street route on map, while it was possible until about a month ago. The features of my software are as follows: Version: 12.205.20430 (64bit) License Type: Academic RPS Expiration: 2021 - 06- 30 Best regards, Milad

Hi guys, It’s been a while that I am not able to link two nodes on ArcGIS World Street Map. The error is: “A route could not be created between ‘TransferNode1’ and ‘TransferNode2. Either a route doesn’t exist or the routing service could not be contacted’. I tried different locations, but got the same result. This is while there wasn’t any problem before and the quality of my internet connection is ok. I am wondering what the problem is! Thanks in advance for the answers, Milad

To Whom It May Concern, I also have a very similar issue with multiple entities and multiple paths (for some entities). Could I also have the solution shared in this forum? I have tried multiple sources, transfer nodes, and sequence tables. I just seem to be running into different errors trying to achieve the same goal. Thank you, in advance, for your assistance!

Today, I found this topic talks about updating data in real-time when simulation is running. I thought it could be useful for me in the future so I decided to try it myself. But, when I used the Read/ExcelRead Step, I found it only "read" the external file at the first time: It seems the Read Step creates a copy of the external file at the first read and then it will use the copy for the future reads within the simulation. For example, at the start of my simulation, I used a button to call ExcelRead Step to read a excel file. Then, I manually changed some values in the excel file and I called the ExcelRead Step again. However, the second ExcelRead Step didn't read the changed values.If I want to use the changed values, I need to restart the simulation. For the Write/ExcelWrite Step, only when I stop the simulation, the external file will be updated. If I don't stop the simulation, no matter how many times I call Write/ExcelWrite Step, the external file is not changed. Are these kinds of behavior bugs? Because from the above topic, I think the Read and Write step can update the external file within the simulation. My Simio version is 12.207.20659. Thanks to everyone in advance!

Hi LizMB, I have a few specific recommendations for you below, but generally I suggest looking into the SimBit models provided on Simio's Support Ribbon. A PDF opens with each model that contains a detailed description, so they are a great tool for learning specific approaches and techniques. A few that I believe are related to your particular problem are "Moveable Operator", "Interruptible Operator","Keeping Worker Reserved", and "Entity Follows Sequence". Worker1 carries both entities to their respective nodes and leaves them in their respective stations after worker(A/B) "checks them" (I used a delay to simulate this check) and then Worker1 moves on. For this objective, I suggest setting up your drop off stations A and B as a Servers. Use the Processing Time property to represent the "check" while seizing both workers needed (see the Operator related SimBit for more information). Make sure all entities are assigned a sequence, so Worker 1 knows where to drop them off. The worker(A/B) only picks up the entity if needed. So if the worker was with another entity in process (like Srv(A/B)), he would go check the new entity so that worker1 can move on, but would return to finish out the first entity to the end. Assign entities that enter the pick up stations a higher priority, and interrupt the Workers at SrvA and Srvb if a pick up task arrives (See Interruptible Operator for more information). Ensure that the Workers have the needed paths to travel to all of the destinations required in all directions. Currently, WorkerA and WorkerB cannot travel to the Outputs of the Servers. Other suggestions: Look into using a Timer Element that could trigger the entity creations at SrcA and SrcB. That should remove the need for Source1 and Sink1. If the Worker's travel doesn't need to be defined by a path, I suggest setting the Initial Travel Mode to 'Free Space Only'. The error message you are receiving is related to the Add-on Processes on the A and B nodes. Whenever Worker 1 enters either of those nodes the process is triggered and tries to complete the process with relation to the Worker. Restructuring the model with Servers in this area should help you get around this issue. Thanks, Ryan

I'm having some trouble with worker actions and transfer steps. Below is a picture of my current model. I have also attached the simio file itself. What I want to happen: Worker1 carries both entities to their respective nodes and leaves them in their respective stations after worker(A/B) "checks them" (I used a delay to simulate this check) and then Worker1 moves on. The worker(A/B) only picks up the entity if needed. So if the worker was with another entity in process (like Srv(A/B)), he would go check the new entity so that worker1 can move on, but would return to finish out the first entity to the end. My problem: Worker1 doesn't wait for the other workers to check and move on, just puts in station and moves on. I can suspend and resume the processes and get the worker to the (A/B)PICK nodes, but the worker picks the new entity up and starts that. The entity they were working on before just vanishes or something. Then everything becomes a standstill. Lastly, I run into this transfer error so much, and can never figure out exactly what causes it. ModelForQuestionCOPY2.spfx

Hi I want my simulation to start with some entities at the output node of a server. Is that possible? Thanks in advance Janus

Hi I need reference to some sort of property that can help me store entities in my transfer node(shelf). I have used the Park property but then I am not sure on how I can release it when the transporter is told to arrive at the transfer node(shelf) to pick up certain of those parked entities. Any help is appreciated. Thank you

Thanks Adam for the reply. I know a fair amount about Processes; I just needed a clarification about some aspects related to large models created using tables. The example I mentioned in the original post may be simple but it could easily scale to include 100's of locations. I will give some examples of these aspects that get tricky in such large models below. Thanks Glenn for the clarification. The tip about finding where processes are being referenced in a model is great! The MultiEchelonSupplyChain example may look simple, but it has the potential to be complex. When I asked the question what I had in mind is a similar model but with 100s of locations like DistributionCenter and Retailer (Basic Nodes). Imagine you want 300+ basic nodes (like in my case) to have the same add-on process. Imagine having 300+ inventory elements that you want to write statistics for using a Write step. It's tedious to do things manually. As for referencing the same add-on process for 100s of objects (basic nodes in my case), I found a trick, which is to add the add-on process to one of the objects and then sub-class it so that the process becomes a default for the newly sub-classed object. Then change all the other objects to the new sub-classed object. As for writing statistics for 300+ inventory elements, I couldn't find a way to automate the process. To be clear, I want (for each inventory element) to write statistics at various points throughout the simulation run. The standard reported stats for inventory elements are only "Totals" or "Averages" or a function of the two. What I want is to see how a statistic changes over time, so I need to write to a CSV file using a Write step. When working with large models, there's a need for automating some modeling aspects. Creating objects and elements can be easily automated using tables. It's dealing with these created objects and elements that sometimes needs tricks and workarounds to automate.

Hi Ryan, Thank you for the corrections. As always, spot-on advice, that is very appreciated. I do have a few follow up questions. - Do I set the Initial Sequence property to 'Sequence1' or do I need to tell it the row too? 'Sequence1.Sequence'? Sequence 1 is working, but just wondering. - In the SimBit, Entity Follows Sequence With Relational Tables, there are three types of Entities that all flow through the same source with the Source Property, Table Row Referencing, pulling from the JobTable with the Row Number 'JobTable.ProductMix.RandomRow.' For my model, I have two different entities and the source Bldg is supposed to pull BOTH entities with the Table Row Referencing, "JobsTable" with Row Number: "JobsTable.NumberWorkers.RandomRow." But when the model is run, only one entity is ever used. The Table has an ExpressionProperty of Random.Triangular(3,6,9). Is that the problem? The SimBit's table was an actual number. I tried replacing the Expressions with actual numbers and the Entity switched to use the other one but I am still not able to get half the 34 to be one Entity and the other half to be the other Entity. - How do I get the Vehicle to carry its max capacity? The capacity is set to 6, and it only carries up to 4 entities around at any time. This is incorrect, as the Entities are supposed to be grouped into work teams of Random.Triangular(3,6,9) for their initial Source output move. Afterwards they can be individuals or work teams. The Bldg has the Entity Type defined as the JobsTable.Specialty so it should pull from one or the other (like the below mentioned SimBit), and the with Entities Per Arrival Set at 35; and the Entities themselves are set to a population maximum of 17 each and I get a Runtime error of maximum number exceeds limit for the entities. Why doesn't it hit the limit and then pull from the other Entity? - I'm confused about the network you mentioned above. I thought the nodes had to be linked directly (output to input node). So the busy nodes have a lot of paths radiating out from them and it makes it a little messy. Is there a cleaner way to show the routing? Thank you,

Hi M_A, The sequences in your table are never assigned to the entities before or as they are created. Assigned the sequences by selecting the entity instances in the Facility view, and set the Initial Sequence property under Routing Logic to 'Sequence1'. Also, the Entity Destination Type property on all of your Transfer Nodes, including the outputs nodes of all Servers, must be set to 'By Sequence' in order for the entities to follow the sequence appropriately. Here are a few other things I noticed while looking over the model: All of your Servers only have the capacity to process 1 entity at a time, so for your case only one employee can work in that area at one time. As soon as each employee is done working they will request a pick up 1 at a time. May not be what you are looking for here. The processing times at the Servers aren't linked to the table. You can link them by setting them to 'Sequence1.ProcessingTime'. Be sure to set the appropriate units in the column properties of ProcessTimes. It is hard to see the network that is available for the Vehicle, so one more thing to check is that the Vehicle has all of the needed paths to pick up and drop off the entities. Thanks, Ryan

Hi M_A, It is difficult to determine what could be causing this without seeing the model. Here are a few things I suggest investigating: Ensure that your model run time is set run long enough for all of your entities to flow through your system. To test this, I would set your model run time to Infinity, and create 1 set of 35 employees. Then see how long it take for the model to cycle through all entities. You may be able to use some Animation at this step to see where the entities are getting stuck. Along with #1, I suggest turning on the Model Trace and reviewing the steps taken for each of your employees and the bus. If you are using an unbounded random distribution (for example a normal distribution) for any of your processing times, then the result of that distribution could be something very large. You should be able to see if that is the case within your Model Trace review as well. Lastly, make sure all of your Transfer Nodes are set to route By Sequence and require the bus for transport. Hope this helps. Thanks, Ryan

I created the model below to emulate a container Terminal actual stock on the floor using nodes

You can place some enough transfer nodes at different distances and directions (In freespace it will be hard to stop modelentity object and seize the server object. This can be quite challenging task). Then you can randomly send the modelentities to one of these transfer nodes (This is for sending entities some vector away from the source). Then, define an entered add-on process trigger for each transfer nodes and place a move step onto this add-on process. In resource movement request of this step define object type specific (or from list), object name any server (or from list you set), and destination node as the transfer node itself. Then, you can try seize step to or transfer step to send the entity onto server object. You have to try some options.

I have made a small model with the issue. You will see the green MyVehicles start at two nodes. MyVehicle[1] is further away, but will be selected first. I want MyVehicle[2], the closer of the two MyVehicles, to be selected first. I only want the blue Vehicles selected if both MyVehicles are in use. SmallModel.spfx
