Hi Simio, Is it possible to model a block of raw material being turned into a part and swarf? I.e. a single part entity being split into two different part entities? Thanks Kevin

Im creating a model that has different entities and it has to go two different servers. The problem have is that each entity has different process time at each server. Can someone please help me? I try setting up table and it did not work. Thanks.

Hi, I´m looking for a solution, that a source can create different entities (Part A, B and C) in a certain order (and then repeat it, not based on random). For Example: 1st Arrival Part A, 2nd Arrival Part B, 3rd Arrival Part C, 4th Arrival Part A (and so on). Is there an opportunity to realise this? I tried to use a data table, but probably I missed a necessary step. Thank you for helping. Chris

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. ***********************************************************************************

Hello! With your current approach, you need a way to aggregate the distance traveled per each entity. Each entity in the population is collecting their own distance traveled, but on the Output Statistic, you are looking at just the Instance, ProductA. The Instance will not automatically aggregate the population's values. If you were to specify a specific population index, for example ProductA[5].DistanceFunction, the Output Statistic would return the 5th entity in the population's distance function and you should see a value. However, making an Output Statistic for each population index would be inefficient and tedious to collect. I recommend using a global/model level State Variable. This State Variable could be summed as a ProductA entities leave the system. So the Product A entities will continue to collect their individual distance traveled as you have set it up, but then prior to exiting through the Sink, add their distance traveled to a running total State Variable. That total could then be divided by the number of entities destroyed giving you an average distance traveled.

Hi all, I'm trying to do an information network model, and I need to have hundreds of thousands of "nodes" in this model, each node would need a source, server, and maybe a sink. And the "nodes" need to be connected to each other as well. Is it possible do create such "node" automatically instead of manually creating them? And would the runtime efficiency be okay? or should I switch to other simulation software/language? Any suggestions would be appreciated. Thanks!

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.

I have a model where I have 7(seven) entities and for each entity there are many possibilities paths. Is possible an entity be programmed with multiple sequences tables? For example, the entity can go to source -> server1 -> sink, and also randomly it can go to source -> server2-> sink, something like that.

Hello, I am very new to Simio and still learning. I have 2 different entity types, Long and Short. I have a source which goes to any of 2 available workstations, no restrictions needed here. Those 2 workstations then need to send their processed entities (randomly Long or Short) to 2 other workstations, Saw A and Saw B. If the entity is Long, it absolutely must go to Saw A, if it is the Short entity, it must prioritize Saw B, but if Saw A is available and Saw B is in use, it should go to A. How can I do this? Thanks in advance. Samuel

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

Hello. Is there a somewhat simple way to delay the start of a server until a fixed number of entities are in queue? If I have a server with a capacity of 6, and I want it to process 6 at a time, thus not starting before 6 entities have accumulated in the queue. How would I go about doing this? Thanks.

Hi John, you can set up a timer. This timer fires a process every 365 days. In the process you can register the destroyed entities. Hopr this helps Rds. Mauricio

Hi, I have a bottleneck at the end of my assembly line. I cannot dupplicate that station as my total number of workers is already high. Before hiring, I would like to try and reallocate and have satellite employees. I want to allocate my workers to that station when the input buffer has exceeded one entity. Every worker has to finish the entity they are presently working on at the other stations and the first workers that are done need to go the bottleneck station. The rest of the time, the workers can be allocated based on the smallest distance to the work stations. The bottleneck station usually requests 4 workers. That information is already set up in a table. When there is two entities in queue in that buffer, I want workers to be able to go finish the work and hence increase the processing time by X. I have tried a lot of different things, and all my data is stored in relational tables. Thanks!

Hello. I am trying to model the brewing process of a local brewery. They have 8 different types of beer, 6-30 barrel fermentation tanks and 4-15 barrel fermentation tanks. Each "job" is 15 barrels, therefore if two "jobs" are the same type of beer, they may brew together in a 30 barrel tank. 15 barrel jobs can still brew in 30 barrel tanks, they just cant mix with an unlike entity. I am relatively to simio, so please if you can explain in simplified terms that would be good. I need to know how to make sure that only identical entities brew at the same time within a 30-barrel tank. If the beer already in the fermenter does not match the beer that is coming into the fermenter, then it needs to be blocked and sent to another open fermentation tank. Any help is greatly appreciated...same rules apply for 30-barrel brite tanks (the next step after the fermentation tanks)

In the attached model, I want to transfer entities to stations depending on some criteria defined in a table. I have 2 types of entities, "A" and "B", defined in a table as primary keys. Also I have 2 states, "Good" or "Bad", also in a table as primary key. Finally I have 3 stations. I have a table that has 3 columns, “Entity_Type”, “Quality_Type” and “Station”. For example a row could be "A"; "Good"; "Station 1". It is possible for entity "A" with "Good" quality to end up in either "Station 1" or "Station 2", and in that case I want to randomly select one. The problem is that I cannot use a RandomRow based in more than one criteria. Either I use RandomRow for the rows of the table that are type "A" or quality "Good", but I am not finding a way to do more than one combination. This model is a simplification of the real model which is more complex and has hundreds of combinations. Model_RandomRow_FilteredTable.spfx

Hi, I have a problem with entities in the queue. The process is in the MemberInputBuffer of a Combiner and I have to create different materials for each entities in the queue. So I put in the process a search step searching for entities and then other steps (assign, delay etc) to go to other tables to create the materials related to each specific entity. The problem is in the first search because in “collection type" I have written “entity population” and in “entityType” there is the reference to a table with all the entities in the system. I need to search only the entities in the queue of MemberInputBuffer (and now the steps search all entities in the system) but I'm not able to find the right "match condition" to restrict the search only to the queue. Can you help me? thank you Best Regards Irene

My model assigns capacity of 8 to a server. Two types of Entities arrive...A and C. Before each entity is processed, I am assigning the server's process time using two different random distributions, one for A types and another for C types. My question is whether or not the processing times for any 8 entities in the server at a given time will process to different process times? Or, will the process time of the last entering entity reset the process time for the others that are already in the server?

Hello, We are evaluating Simio and really like what we see from exploring the Simio Personal Edition. Custom Dashboards are a high priority for us and we appreciate the fact that Simio seems to allow creation of custom dashboards from within a model; however, we would like to know if Simio allows the creation of custom dashboards that are portable from model to model. For example, we would like to: Create a dashboard that displays a chart depicting activity cost per entity (for a selectable set of entities) over the simulation period. Reuse/import this dashboard into any model to display the activity cost per entity over the simulation period (for a selectable set of entities). Two questions: Is this possible with Simio? If yes, which edition(s) of Simio support this capability? Thanks in advance! Donovan

Hello, I am trying to imitate what you can see in a factory. For example, I created a couple of materials that could be produced and consumed. Process: I created materials. For definitions, I created a produced material that will get the material from a table. Afterwards, I selected a task processing(sequence) under server. I added all the materials that needed to be produced. On task sequence I selected the materials tab to consume each material, but all the entities are running under 40 different materials. My desired output is to see only 1 entity running producing and consuming 1 raw material. Joshua

hi taylor, before the paralel servers place a combiner object. On combiner object set the right logic for batching. Then again set a logic for sending the batched entities to the appropriate server. I feel you should set this sending logic on the links to the servers. Hope this helps!

Hi I have created a subclass of Entity and named it AgentBase. My new Entitytype AgentBase contains a station and a queue which is showing the content of the station. I have added a process OnCreated which is creating two additional AgentBase-Object and transfer the additional to the station. I have now two problems: - There is only one entity shown in the queue with the contents of the station - instead the two. I want to show all in a line. - The showing entity in the queue have the wrong direction I have added my project where you can see the problems. Hopefully someone can help me. Thank you. Best Regards Thomas AgentLibrary.spfx

I have created a Customer Data with different types of Model Entitites, defining the mix on each one of them. Once the model is running, a message appears saying "The maximun number in system limit for objects of [name of the model] has been exceeded. A possible cause is that the Maximun Number In System has too small of a value". However, I haven´t set any kind of property for the object. Does anyone know how can I solve this? Thank you!

Hello All, I'm trying to create a model that will keep track of processing time for each transaction processed and reroute transactions that exceed a processing time threshold to an alternate sink. Initially, I attempted to rework the "Remove from Allocation Queue" Simbit, but the "Remove" process only seems to work with queues. The model itself is very simple. Single source with a random exponential inter-arrival time, single processor with capacity of 50 and 2 sinks; one for completed transactions and one for long running transactions which are manually routed. Any guidance you can provide would be greatly appreciated. Thank you, Ryan

How do you define a new state variable for an entity type? I mean here the things that arrive and travel through he model (they would be temporary entities in SIMSCRIPT II.5, transactions in GPSS/H, workpieces in Simul_. I have consulted the online help, and gone through the SimBits that looked as if they should be relevant, but cannot find an answer anywhere. I am attempting the embarrassingly simple task of randomly assigning a priority, 1..3, to an entity on arrival into the model, and later having them queue FIFO within priority class for service. As I do not need dynamic priority I expect a parameter would do instead of a state, but either way I cannot find how to perform the simple task of defining a field for an entity class. Once that is done I expect assigning to it should be easy. All the best, John.

I am recreating the model 5.3 of the Simio and Simulation textbook. When I create the list and run the model, with selection expression in the output@placement node as below candidate.Node.AssociatedStationOverLoad, all entities goes only to finepinchfaststation. However, when I use Candidate.Node.AssociatedStationLoad it selects all desitnation loads. Is there any change to the Candidate.Node.AssociatedStationOverLoad? I displayed the values in the facility window and it is coming as -infinity. Model_05_02.spfx
