How to increase the distence between entity to entity ?
ViniciusF replied to River's topic in SI General Discussions
To make an entity wait until the runway is free what you could do is set the Initial Traveler Capacity of the Runway path to 1. This way entities will wait at the node before entering the path. I did not understand the first question, but if you need entities to visually appear behind one another, set Allow Passing to False on the path. Alternatively, you could use conveyor instead of path to make entities allign and respect some distance. Hope it helps. -
Hi John, The entity is requesting a ride from the vehicle and the vehicle will seize the driver if available. However, if the vehicle is unable to seize the driver, it will reject the ride request and the entity will move to the Global Visit Request Queue, as you are seeing. You can attempt to have the Vehicle check again if it can now pick up the entity, and it will run the process to check if a driver is available. To have the Vehicle check the Global Request Queue to see if it can give a ride, use a PlanVisit step. Ensure that the Vehicle, in this case Vehicle_A, is the object executing this step. By default, the Vehicles are not aware if the Driver they need becomes available. You might consider using a Subscribe step on the Vehicle's OnInitialized process. This Subscribe step can watch for an Event and if that Event occurs, can trigger a related process. For example, the Vehicle might wait for the Driver.Released Event. When this Event occurs Process1 could run. In Process1, the Vehicle could execute the PlanVisit step. For more information, I recommend the Help pages in the Simio Reference Guide titled "PlanVisit" and "Subscribe". Happy Modeling!

Change Server Capacity over time with WorkSchedule
JanainaF posted a topic in SI General Discussions
I have a model where I need to set a server had a maximum of 15 entities from 7 A.M to 10 A.M. I Use the WorkSchedule but I don't know how to limit the number of entities. Can someone help me? *This server it is parallel with other servers. -
Hi!! I want to know in which object (in this case filler) my container entity is when certain event occurs. Is there a way to access this info? Thank you so much! Teresita

Sorry if this is obvious, but can someone tell me how I can reference the number of batchMembers in the example above without having to reference the specific entity, which in this case is TruckLoad.5442. I need something like "the number of batchMembers in the entity currently in the ParentInputBuffer" please. e.g. TruckBay1Batch.ParentInputBuffer.Content.???.BatchMembersCount? As you'd expect, this number changes constantly during the simulation run. At this moment of simulated time, the answer is 2. Thanks for your help!

Is there a way to create a column of Time property without date using Simio Table, just like the start time and end time of day pattern of the work schedules? The work schedule doesn't suit my needs.

Normal Distribution for Table Row Referencing
ViniciusF replied to Grant S's topic in SI General Discussions
Hi, What you could do is set up another column with the weights (likelihood) of creating each entity type... so you can set up probabilities any way you want it. Look SelectEntityTypeFromTable - SimBit to learn how to do it. -
Hello! I want to make the simulation model which illustrates about the interference time about three kinds of truck. And such trucks enter the warehouse and head to the specific loading spot to do forwarding operation with one goods among four kinds. That is why interference time occur, by which I mean that I have to make model to find the most suitable spot for each goods forwarding activity by switching each spot. However I can not find the accurate properties avoiding each other objects at path, or even allocating several time delay on the situation that they encounter. Anyway, I want to see object avoid each other by decelerating its speed and calculate overall time delay at the result tab. (20 seconds per each interference) If I can apply the time delay, the kind of the object does not matter. I already tried to make the entities play a role as the truck that works mentioned above, but that trial was failed because there are no property to decelerate, or avoid at least.. I sincerely want my dear SIMIO to achieve a success in this modeling.. Thank you! -
I'm having trouble calculating the average time between Objects. I know there's some built in function called time in system to get entity totle time in the system. But now I care the time entity spent between nodes. EG: I have entityA, entityB, entitleC, I want to find the entityA average time spent from server1 to the server6, from server1 to the very end, from the very begining to server4? How should I do these, what does the expression look like? I want to add a label to show that numbers dynamically during the run of the model.

Hi, I am trying to demonstrate a manufacturing process flow, by doing so I want to show a visual progression of the entity through the entirety of the simulation. Setting Random Symbol on to 'True' is not what I am looking for. I have 10 entity symbols and they have to change specifically between servers. How is that possible? Thanks,

I am working on a simulation of a number of firms processing raw products. If I represent the firms as resources in a server -so that the server capacity represents the number of firms, how could I identify which resource/firm processed a certain batch of products? Can this be done with a server having a capacity of its own, or should I use a pool of (secondary) resources with id labels so I can use that id to label the product batch? -
I used rate tables once, these events per hour does not guarantee that you'll have that amount of entities on the time interval. It varies from replication to replication. Sometimes you'll generate less, sometimes more.

I'm still experiencing the same problem and haven't been able to fix it. I could use a regular arrival table, but then my pattern would not be a non-stationairy poisson process. So I think that I really need to use these rate tables, but somehow the inputs of the rate table don't reflect the outputs.

Got issues with a combiner. i have a server that processes the member parts but has a 0.1 probability of going to scrap, this means the batch size has changed. the parent part has a integer state that gets updated when this happens but doesn't update the combiner batch quantity property. I have attached an image showing this issue. you can see the pallet number displayed which is the way i match the parts with the correct pallet. the pallet(parent) also displays the batch size using the same integer state which i use in the combiner logic. Theres a pallet with 4 items on it and it shows the batch is 4 so why wont that process it? Also attached the whole model so you can look at it all Batch and Scrap.spfx

Is it possible to use neural networks with continious flow library? I have a microgrid simulation model with solar panels which charges a battery and grid are energy sources for a house. Grid charges at different rates based on time of use (TOU, i.e time of day and winter summer holiday etc) and solar company charges at fixed rate as energy is filled into battery. I would like to optimize the system using machine learning so that the house minimizes their bill by deciding when to chose grid and solar.

Hi, I'm making a manufacturing line sumilations where 2 entities representing components enter combiner, where they are being proccessed to a new single entity. How I'm suppoused to terminate those 2 entities that are entering the combiner and generate one new that is leaving? Also, can you combine more that 2 entities in one combiner?
-
Just want to remind you that the values in the rate table shows the offset from the simulation start time. Not actual day time. So if your simulation start time is 7 am your first row shows 7 am to 8am time frame and so on. Hope this helps Regards

Hello, I am new to Simio and am having trouble with altering process times which differ according to the Model Entity. First, a little more about the background of the problem. I am trying to model a call center and have 12 different Model Entities that move through Free Space according to a sequence table. So for example, as part of the model I want a single server called "Sales" but there are three model entities that eventually end up at that server, but each is processed differently. Could anyone suggest a method to model this phenomena that doesn't involve adding additional servers? Thanks. Kevin

Hi, A Separator is creating copies of the entities that enter it, the number of copies depends on a probability distribution, I want the worker to transport all the entities created from the same parent entity at once. Is this possible? I attach the model for better understanding. Thank you so much! Model.spfx -
Hello, I have a network with one source and different sinks. I use add on process on the output of my source to choose the sinks based in the capacity. When I run the model, all created entities destroyed in the sinks correctly but in result part, "TimeInSystem" is equal zero. Due to add on process, is it happen?Should I calculate time in system with Tally? Best, Nadere

Hi, I have an issue related to workers going off-shift and abandoning the reserved entities in different servers, depending on when the shift change happens (picture attached is an example). The shift change is based on switching from Worker of x number of population to y number of population to meet my WorkSchedule. The Worker should always carry different entities throughout, entities cannot travel alone. The logic issue happens as a result of entities left in servers or buffers that were not picked up by workers due to the end of shifts, causing too many objects/entities in the system not destroyed. An expert suggested to build process that checks the Worker's Allocation Queue when it goes off shift to see if there are any entities in it, and if there are, turn the Worker back on shift. I tried to build that process, but I could find the right steps. Any help on identifying the right steps or a different way to model workers shifts is appreciated.

Prioritize certain entities and interrupt process
svend2000 posted a topic in SI General Discussions
Hi, I'm currently working on the attached model, and currently i have a lot of trouble on making the two operators prioritize the B2C entities. I hope that somebody can help me fix this issue. Just a brief rundown of the model: each day freight arrives at 8.00 and this triggers the sources for B2C and B2B to feed a number of entities, with a corrosponding distribution into the system. Upon the entities arrival to the two "AT-servers" the two operators should prioritize the completion of all B2C entities, before moving to ATB2B. If new entities arrives at the ATB2C server, and the operators is situated at ATB2B, they should interrupt that process and focus on ATB2C. The prioritizing and interruption is based on the simbit: InterruptibleOperator.spfx Best regards Kasper MySimio.spfx -
Hi everybody! I want to know if it is possible that an entity can change from one server to another if the another server is available and the entity isn't still processing. It means if it is possible that an entity can exit from the input buffer of the first server. Thanks for your help. Best, Albert.

Hi, I am looking for an event which can be used in a Wait step in a process which is triggered by an entity finishing processing in a station. Also potentially an event which is triggered when an entity exits a station. Do I have to manually fire an event with an addon process from every station which I wish to do this?

Entities in a buffer at the start of the simulation
gocken replied to Ondrej's topic in SI General Discussions
Try the logic included in this model. Note that you can use the same logic at any time over the simulation run. In this specific example the entities are created at the begining of the simulation run. If you need to create them at any time over the simulation run then you should define a seperate process then embed the same logic into that process. Then, all you need is to trigger that seperate process. For example, you can trigger by using timer element. Hope it helps?. CreateEntities.spfx
