Hello, I am trying to use git to track changes when working on Simio projects collaboratively. For this I am saving the project as *.simproj and the resulting file and folder structure looks good. But there are too many time stamp changes that make it difficult to track the "important" changes. For example, I only changed the location of the DefaultEntity in the model and hit save. The resulting changes are shown in the attached screenshot, with 20 files shown as changed. The main changes are related to the time stamp. Is there a way to configure Simio such that fewer files will be affected by each change? Thank you. Annika

Hi Annika, Check out the Support Source Control option in the Project Properties. (Right click the project in the Navigation Window to access Project Properties)

Thanks Devdatta, That's a great contribution.

Simio’s neural network implementation allows the import and export of ONNX files, which ensure that Simio is compatible with many machine learning frameworks. This format is well-documented, and there are many third-party packages and applications that can help you convert machine learning models to/from ONNX, or to open and view ONNX files. The attached document provides a basic summary for several of these packages, including tensorflow-onnx, onnx2pytorch, and Netron. Please note that none of these packages are affiliated with Simio, so any issues or limitations of these packages can be discussed on the package’s GitHub page. ONNX Format Utilities.pdf

People often want to model two or more vehicles or entities moving together. There are a few components to this: 1) Seizing the resource appropriately - can be done in processes, but often best done within the vehicle object to make the modeling easier. Here, a vehicle has 4 properties added to support use of an operator. 2) Animating them moving together - the picture below shows use of a second queue animated on the custom vehicle. 3) In some cases, you also need the "driver" to be shown moving. The Attached Animation Speed illustrated below, accomplishes that. I have attached a model that uses a custom vehicle object to model a wheelchair which is "driven" (pushed) by a person to pick up a patient. *********** FOR VERSION 190 AND EARLIER ************************************* VehicleWithDriver.spfx You could use the same approch, possibly with just animation changes, to model something like a truck or forklift that requires a driver. In fact, I just added a second model to that same project that illustrates use in manufacturing (e.g. a lift truck and driver).VehicleWithDriver.spfx VehicleWithDriver.spfx *********************************************************************************** ************** FOR VERSION 191 AND LATER *********************************** VehicleX3.spfx VehicleWithDriver_VehicleX3_Examples.spfx For more information on the update, see the post below. ***********************************************************************************

Entities are prioritized in server according to the server Ranking Rule. Check my attached model. I set Entity1 priority to 1, Entity2 priority to 2 and told the server to prioritize the ModelEntity with the highest priority value. You can play with that logic to prioritize everything the way you want. entity priority.spfx

Hi jord41, Simio loads the bound tables once during the initialization in the Simio tables. Data access requires a lot of computing time. (More for writing as reading). I see that you only have 1 column of integer values. My recommendation is that you do not import the table into a Simio table. It's best to create an integer or real state of type vector. Then you use e.g. the Read-Step or the ExcelRead-Step. In conjunction with a timer or the sample example loop of GFurtado you can load the data at intervals. I think that this could be a solution. At least that's how I would do it if I had to work with real-time data. Normally, such real-time data is written to a SQL database by a PLC or something like that. Then you can use the SQL steps anytime in Simio. Best regards Pascal

At some point I would start looking for a SCADA system, write it in Python or anything outside Simio. A Simio Engineer would be better suited to help you, but I still believe you could build this inside Simio (maybe through an API?). I manage to build a very ugly version of this that kinda works. It's not real real-time, because I still need to click on the manual import button (I don't know how to help you with this). I set my source's Arrival Mode to On Event; Create a process with a Decide step that checks if the table received a new value: If it received a new value, trigger SourceEvent; If it didn't, check again a second later. As I said, it's not very elegant, but I hope it inspires you to find the right solution.

Hi all, I met some questions in building the model. It seems a very general quesiton but I didn't find any solution from internet... I'm building a general workflow model. I want to decide the quantity of a server to optimize the workflow. I want to use experiments or optquest to get the 'best' number for each server. If I set the capacity type as Fixed, then I can set the initial capacity as ''referenced property'', then I can use this as control in experiments/optquest. However, I have a work schedule for each server now which means I couldn't set the capacity type as Fixed. And then I couldn't set capacity as ''referenced property''. I don't know how to control this capacity in my experiments/optquest. I know I can change the 'value'(which means the capacity) in workschedule table. But I can not change this number flexible in experiments... Or I don't know how to set this value as ''referenced property'' . Is there anyone who could help me with this? Thanks a lot!

Thank you .. this is amazing stuff. By the way, is it possible to import and export Process step as well?

Is there an example or a SimBit which shows how to do this?

Simio is a simulation modeling framework based on intelligent objects. The intelligent objects are built by modelers and then may be reused in multiple modeling projects. Objects can be stored in libraries and easily shared. A beginning modeler may prefer to use pre-built objects from libraries; however the system is designed to make it easy for even beginning modelers to build their own intelligent objects for use in building hierarchical models. An object might be a machine, robot, airplane, customer, doctor, tank, bus, ship, or any other thing that you might encounter in your system. A model is built by combining objects that represent the physical components of the system. A Simio model looks like the real system. The model logic and animation is built as a single step. An object may be animated to reflect the changing state of the object. For example a forklift truck raises and lowers its lift, a robot opens and closes its gripper, and a battle tank turns its turret. The animated model provides a moving picture of the system in operation. Objects are built using the concepts of object orientation. However unlike other object oriented simulation systems, the process of building an object is very simple and completely graphical. There is no need to write programming code to create new objects. The activity of building an object in Simio is identical to the activity of building a model – in fact there is no difference between an object and a model. This concept is referred to as the equivalence principle and is central to the design of Simio. Whenever you build a model it is by definition an object that can be instantiated into another model. For example, if you combine two machines and a robot into a model of a work cell, the work cell model is itself an object that can then be instantiated any number of times into other models. The work cell is an object just like the machines and robot are objects. In Simio there is no way to separate the idea of building a model from the concept of building an object. Every model that is built in Simio is automatically a building block that can be used in building higher level models.

It seems the approach I had in mind was much more complicated than necessary. Thanks to your suggestion, I was able to resolve the issue. After applying your method, it worked seamlessly in my model. Thank you very much for your help.

You could improve this with a monitor inside a subclassed vehicle verifying the ResourceState change and executing a process to add the wages aswell. But for now, I think the solution above is fine.

Simio academic offering is not compatible with commercial offering. There is no way to convert the model to be workable in commercial version by the end-user.

Hi! Yes, there is a way. What you could do is use a String.Format expression. This way you can show multiple variables on the dynamic text. On your case something like: String.Format("{0}: {1} {2}{3}: {4}", "Material Costs", MyModelEntity.MaterialCosts, String.NewLine, "ProductionCosts", MyModelEntity.ProductionCosts) should work. As a plus, you could use a state to disable/enable these labels with a button and a process. Something like: Math.If(EnableTxT, String.Format("{0}: {1} {2}{3}: {4}", "State1", ModelEntity.State1, String.NewLine, "State2", ModelEntity.State2), "")

I have attached a simple model using model states to illustrate. I think it should work in a similar fashion using entity states. First, I define the states: Then use those states as Sequence destinations: Until you provide each of those states a value, the Sequence will make no sense and the entity won't know where to go. So on the Source I use an Assign to initialize all the values. This will direct the entity sequentially through Servers 1-4, and then to the Sink: Finally, just to illustrate the technique, on the output node of Server3, I interrupt the normal sequence by Assigning it to instead go to Server5 as its 4th step: If you convert these states to Entity states instead (I was just lazy), I think it should work the same but allow you to selectively override any Sequence Step at any time.

Hi, Your issue is that Input@STBR_01_54 is a reference to a Simio object. You want to write out the string name of the object. You should use Input@STBR_01_54.Name Regards, Lucas

since exclusion property checks the expression at the start of the simulation run to determine if this step should be excluded from the run my suggestion does not work. simply omit this suggestion:( and thus decide step before the tally step best suits your purpose.

simply increase your customer types as credit card and cash payers. For example, expand your table by includeing customer1creditcard and customer1cash, customer2creditcard and customer2cash, customer3creditcard and customer3cash? Also, rearrange their probabilities, sequences, etc. as well. Is it ok?

I have attached a simple example of one approach. 1) I edited the ModelEntity object and added a state array of type MatrixFromTable. This type of array is automatically initialized from a table. Ideally I might have also added a table to the entity, but Simio doesn't work that way. Instead, I added a RepeatGroup named InitializationValues consisting of a Real property. I used this repeat group as a way to essentially add a "table" into the object, since internal to Simio there is almost no difference between a table and a repeat group. 2) Back in the model I added a table and then imported data into that table from Excel. I used 10 rows, but I could have imported 350 rows with no change to anything else. 3) Now when you place the ModelEntity object into a model, you can pass a table into the InitializationValues repeat group. Again, intead of just typing a bunch of values into the repeat group, I just say go get the whole repeat group from a specified table. This has the result of sizing that state array inside the model entity to match the current size of the table, and then initializing the state values to whatever is in the table. 4) If you run the model, you can open the Watch window on any entity and view the values of its states. I expect this won't solve all your problems, but maybe it will give you a fresh approach to consider. ImportStateValues.spfx ImportStateValues.xlsx

As we approach our final stage of our bachelor studies, it is necessary to write a bachelor thesis. In this context we are developing a Simio Plugin, which enables advanced model-management and more important, model-comparison. Our main objective is to provide the Simio Community a properly working Plugin, which improves the modelling process itself and the usability within large Simio-projects. What could you expect? Functionality We separate the plugin in two logical components. The first one is called Modelmanagement. The features of this component are the following: • Versioning models • Clone an existing model The interesting part on this feature is the clone mechanic. You are now able to create an identic clone of an existing Simio-model, which can be altered afterwards. This functionality is key to the comparison process. With this clone-function, each clone now represents a version of your base-model. The clones can be altered autonomically. It enables to test and experiment with the behavior of your model, without many workarounds. It may help you to even optimize your model. The second and more focused feature is the ModelComparer. Once you are done cloning and altering your models, this feature helps you to compare several experiments. The comparison isn’t only limited to experiments within one model, you can compare all the cloned experiments as well. Our model-comparison compares responses of several, different experiments. You can now compare all your clones to determine which one is the most efficient. What are we delivering at this point and why? Attached to this post you can find several files. To ease the installation and setup process of the Plugin, we also created an installer. The installer will setup the required changes and files for our Plugin. It is easy to use and enables the full functionality, like a normal software-installer. Second, we wrote a short manual to show you the features of the Plugin and illustrated it with pictures. Our goal is to gahter feedback as early as possible. Currently, we are in the middle of development and are eager to improve the tool even more. We ask you for your feedback, because it is very important for us to find out, if the tool is viable, how its usability is and if the provided functionality is even appreciated within the community. As we mentioned we are halfway through the development-process, the possibility is given, that some bugs or errors may occur. We also would be very pleased if you could take the time to report these and your experience with the tool and fill in the online survey. Your feedback is very appreciated!

I set ModelEntity.Priority = X at Output@SourceX State Assignments property, but it could be assigned anywhere before the server.

Updating the data mid-run isn't a good simulation practice, unless you're building some gimmicky application. But I manage to work this out with this little guy in the Table Ribbon. Have you tried it yet?

Simio has a number of enabling features that are not widely known. When you save a project file, most people use the .spfx extension which is a compressed binary file. But if you would like to take advantage of a version control software (VCS), you generally want the VCS to manage versioning and file compares and file compression, itself. Simio has a multi-file project format referred to with a .simproj extension, which is designed with exactly that purpose in mind. Ths format involves a single key simproj file and a related set of folders that contains the uncompressed version of all the included components. This allows VCS to recognize when a small change to your model is made that it only needs to save that small change and not the entire model. While this works with any VCS, internally at Simio we use Tortoise SVN (http://tortoisesvn.net/) which works quite well for us. Simio also has some built-in features to help track and maintain model/library versions. If you right-click on an object (a model) and select "Properties" you will see a set of model properties for that object including Version. This version number is referenced when loading this object as part of a library to help evaluate if an object has been changed and if the change should be accepted (more on this below). Some additional model properties including Description, Keywords, and Categories. These are available in your model, plus they are available externally. For example the Sample SimBit Solutions interface uses these properties to help you quickly find a SimBit of interest. Some of them are also used in the Model Documentation Report. Speaking of which, the Model Documentation Report is designed to provide a quick way of examining all non-default parameters in your project. It can be useful to instructors evaluating assignments or as a way to record or share a snapshot of your model data. If you click on your Project name in the navigation window, the click on Models and the Edit ribbon you will see various options for subclassing, cloning, and copying library objects. These options, while subtle, give you greater control over how the lineage of an object wil be handled. You will also see options on this ribbon to protect your object from viewing and editing, and also to describe changes that have been made with the latest version.

Hi Tom, thanks for your help! I've found a solution on my own in the meantime (probably not as sophisticated as yours but it works well). I additionally modelled a small version of the lift itself and created a wait process. The triggering event is "vehicle exits Node X". I used the process for my servers ("after processing"). So whenever a chair exits the node, the gates will open. This is actually quite close to reality where the gate opening interval is not fixed but depends on the speed of the lift and the point in time when an empty chair arrives. All the best, Nico

Because we assign the speed of path 3 and 5 to PathXXX.Contents.NumberWaiting at assign3 step of process 1 which is triggered whenever an entity enters node A. As I said in my previous post this expression may not serve your purposes. This is only for illustrative purposes. Here the message is you can increase all existing entities' speed (but all of them at the same time) on path 3 and path 5 whenever the process1 is triggered. Also, you can trigger process 1 by using monitor elements (which seems more suitable for your purposes). For example, using a monitor element you can track the number of entities on each path seperately and whenever this value crosses some treshold value (got congested) you can trigger process1 using monitor element. Note that in your attached model status labels shows how many enitities exist on each path. At the end, change the assignment expression of assign3 step of process1 accordingly.

why do you use source? In Workstation 1_exited step you can just increase the currentrownumber by one using an assign step and use a create step just after this assign step, set its properties using any table (and also currentrownumber state variable). and transfer this entity to the appropriate place. you do not need to use source step?

for your kind reference Model-Example3 Setup.spfx

Hope the attached model should work for you. Assign state to a specify number of entities.spfx

I have taken a glance at your model. At first look your timer element needs to be revised and you should not change the capacity a resource via a user-defined state variable. Use resource.currentcapacity state variable. I have revised your model and it looks like working. Due to having no more time I could not deeply analysed. see attached file. Resource.spfx

Hi Team, Good morning, I have a question that I need support. On my simulation under Planning tab then Entity workflow I see the Orders that I created, but also some other items that I don't know where those came from. that is using resources. for example, I highlight on the picture attached on red color. OrderWIP01 is waiting for the grinder [1] on the finish1_1, when I looked for it, I saw that is on Phx4.89. What is that Phx4.89? Phx4 is one of the names of the entities. but why does appear as entity and not as a Order? At the moment I looking for why to increase the output, as the simulation is giving me 17 unit per shift, but engineering said that it should be around 20. I want to make sure the simulation is done correctly. Thanks in advance. Regards, Htatton Arm-boom-draft-R1-test-092718-Test-Scheduled-3tacking.spfx

You asked for "a way to start/stop timers on a specific entity without creating a bunch of different events". As I understand it, Enable is just a switch that stops/starts the Timer clock. It has nothing to do with triggering events and does not require any events. So if you set a timer to fire in 60 minutes, then after 10 minutes disable the timer, the timer should fire its event 50 minutes after it is enabled.

So I see what you are trying to achieve, and your approach can be moddelled yet you will need to really know what you are doing if you want to start transferring entities in and out of queue's, as well as adjusting capacity of vehicles to circumvent default routing logic. Alternatively, I would set the Retailer capacities back to one and treat an entity as a shipment from the warehouse to a retailer. I would also look at add a material element to the transporter and each server and utilize Simio's produce and consume functionality to drive variation in supply and demand. This will allow you to utilize the base functionality of the transporters, without dabbling in capacitative resource allocation, unless you fully understand the intricacies of the inner workings of a transporter. Task Sequences embedded within the servers should allow you to easily accomplish your objective (basis production and consumption of material), without needing to utilize process logic and corresponding Produce and Consume Blocks. Hope this Helps.

I have created a simple model that I believe may have solved this problem. I used a dynamic selection rule of largest value first. I then multiplied the entity priority by the time in system. This expression can be extended to include other factors like the equation in the OP. Visually watching the model, it does as expected. If anyone has any suggestions or a better way to model this, feel free to share! I attached the example model. Example Model.spfx

You need to search the queue when the server goes off shift (Search Block_Queue), and Transfer the Students back to the Decision making node (Transfer Block -> Make Sure its the last block in the process). That is the easiest fix, other than setting the input buffers to zero.

Either in the Load Time property or the Loaded add-on process trigger of the object (let's say Worker1) you could add an expression something like this: (Worker1[1].CurrentNode==TransferNode1)* 5 to get a delay of 5 only when at that specific node.

I understand why this is confusing. I think the main confusion arises because your station has a capacity greater than 1. The Simio paradigm is that a resource with capacity > 1 is still a single resource with a single Resource State, but just has the ability to process more than one entity at a time. So if any unit of the resource is in use the resource state is busy, if all units are idle the resource state is idle. With the above paradigm in mind, the ResourceState statistics are not describing individual entity interactions, but rather are describing the transition of the entire resource (all units combined) between those states. The resource enters the Processing (busy) state when 1 or more units become busy. It leaves that state and enters the Starved (Idle) state when all units become idle. The average time in spent in that (1 or more units) busy state was 55.5133 minutes per transition. This accounted for 6994 minutes total or 69.39% of the time. The resource transitioned between the busy and idle states 126 times. By contrast, the Processing (station) statistics are telling you about the entities that enter and leave the processes. There were an average of 1.28 entities in the processing station. The average entity was "held" (processing) in the Processing station for 25.99 minutes. 501 entities were processed. You didn't ask about Capacity utilization, but that also can be tricky to interpret when capacity > 1, especially if the capacity varies over time (which yours apparently does not). Perhaps the easiest to understand is UnitsUtilized. This tells you that of the 10 units available an average of 1.289 and a maximum of 8 were in use. UnitsScheduled is the same type of statistic, but records how the number of units scheduled to be available varies over time. The Scheduled Utilization is the most common statistic telling you basically the ratio of the above numbers. It is a little more complicated than that, but that is beyond this topic.

Dr. Pegden led the creation of the market-leading simulation products SIMAN® and Arena®, as well as the finite capacity scheduling product Tempo (later renamed RS Scheduler). Many of the same team members who brought you Arena and a long line of industry breakthroughs have now focused their efforts on creating the next generation of simulation tools. This very talented team is bringing to bear an additional 125+ years of combined simulation experience to provide you with the best possible suite of simulation and scheduling tools. Simio has an experienced management team to provide leadership in the day-to-day management of the company. Simio also has an Advisory Board of experienced executives to provide strategic input to long term planning. Simio also has a worldwide network of over 25 very experienced partner companies who supply local sales, training, technical support, and consulting services.

The Simio object framework is built on the same basic principles as object oriented programming languages; however these principles are applied within a modeling framework and not a programming framework. For example the Microsoft development team that designed C# applied these basic principles in the design of that programming language. Although these same principles drive the design of Simio, the result is not a programming language, but rather a modeling system. This distinction is important in understanding the design of Simio. Simio is not simply a simulation modeling tool that is programmed in an OOP language (although it is programmed in C#). Likewise it is not simply a set of classes available in an OOP language such as Java or C++ that are useful for building simulation models. Simio is a graphical modeling framework to support the construction of simulation models that is designed around the basic object oriented principles. For example when you create an object such as a “machine” in Simio, the principle of inheritance allows you to create a new class of machines that inherits the base behavior of a “machine”, but this behavior can be modified (overridden) and extended. Whereas in a programming language we extend or override behavior by writing methods in a programming language, in Simio we extend or override behavior by adding and overriding graphically defined process models. This distinction between object oriented modeling and object oriented programming is crucial. With Simio the skills required to define and add new objects to the system are modeling skills, not programming skills.
