  1. 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
  2. Hello, i would like to know if its possible to track the different values for a user defined MyModelEntity state. In my case, i created different states like MyModelEntity.MaterialCosts and MyModelEntity.HoldingCosts, ...TransportCosts ... etc. The values are summed up in a state called MyModelEntity.ProductionCosts. This state is shown as a dynamic label text in my model, so i can see the production cost value at the actual time. But is it possible to see the different values of the MyModelEntity states that make up the production costs for instance during different periods of times in the simulation or at any time? Because i would like to see the values of my states like MyModelEntity.MaterialCosts at certain times in the simulation. Thank you!
  3. Hi, I have a production line with 2 sources. The arrival of entity A in source 1 triggers an arrival of entity B in source 2. Entity A and entity B then enter their respective servers for a processing time. Entity A is processed at table_openings between 10 and 15 minutes with probabilities whereas Entity B is processed at table_MF for 10 minutes. The process type is task sequence. Both Entity join at a combiner. Entity A is the parent and Entity B is the member. Afterwards, the combined entity continue along the production line. I have expected processing times for each task at each server. Before starting a task, a process starts where a state statistic registers the state processing time of the entity. I also put list state to verify the schedule utilization. I have verified visually and the state value for processing time is correct for every station while the simulation is running. What I have observed is that the state statistic average processing time for the servers before the combiner is the expected value, however, all the other stations are 10 minutes off. The simio output has the right processing times for all the stations after the combiner but not for the two stations before the combiner. Moreover, the list state average time busy value are ok for all the stations after the combiner but again the station before the combiner, it gives the total number of minutes it was busy. Also, if i do the average of the state log observation for each station in excel afterwards, I get all the correct processing times. I am guessing it has something to do with the combiner, but I am lost. How can the processing time for table_MF be 10,48 when the processing time is a fixed 10 minutes in the facility window? Why is the list State MF and OP different from all the other list states? Thank you for your help!
  4. 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
  5. Hi All,

    I have a server and I have to write out in a csv whenever the resource state of the server changes like from processing to blocked  or from blocked to processing and so on, I do not have a RPS version. any suggestions to this will be really helpful. Thanks

      Hi Chandak, 
      from definitions tab add a monitor element (i.e., monitor1) in your model and set its state variable name property to i.e., Server1.ResourceState. Also, from definitions tab include an excelconnect element which is a user defined element. set its excel workbook property as i.e., resource_state.xlsx (create a resource_state.xlsx file in the same folder where your .spfx file will run). In processes tab create a new process i.e., Process 1 and in there place an assign step and an excel write step (from user defined steps). Define a state variable i.e., row_index. in assign step set state variable name property as row_index and set new value property as row_index+1. In excel write step set excelconnect property as ExcelConnect1, set worksheet as "sheet 1" (resource_state.xlsx excel file's sheet name), set row as row_index, leave starting column property as default, and add two items such as "ResourceState" and "Run.TimeNow". at last, select process1 and set triggering event name as Monitor1.Event. 
      also, in order to get different resource states in your excel file you can define a work schedule or a failure mechanism on your server object. Hope it works?

  6. Hi All, I'm currently using a old working model and copy-pasted a process from another working model. The process uses a couple of assign using ModelEntity State variables. However when I recreate them in the model where I copied the process, I can't use them I always get an error (and orange box). Those State variables were working find in the old model. Anyone knows why I can't copy them in another model ? Tks to all. Janik
  7. Hi All,

     

    I am trying to look as to how can we create experiments with various schedules in the SIMIO experiment tab.

    Currently I am not using RPS version.

    I have created a schedules for various servers using Simio process logic and schedule table for each server.  I am able to run one schedule and see the resulting performance, but it would be interesting to see how the changes to the sequence of orders changes the performance.  How could I set up experiments to make changes to the sequences in the tables?

  8. Hello, I have a Arrival Table, but I only want to create Entities of a specific part of the Table based on a property. IntCol Entity 0 A 0 C 1 B 1 c So, the source should create all entities with a certain integer in column 'IntCol'. The integer value is assigned by a referenced property that I can experiment with different parts of the ArrivalTable For example: If Property == 0 , create only A and C in the source. How can I do that? All the best
  9. Hi, We have a model where we have multiple entity states. This creates interface challenges in defining and populating these states or changing many of them at a time. My question is, can the UI be bypassed in some way using some kind of batch operations? For example suppose I want to assign 150 entity states using string construction and naming conventions easily set up in a spreadsheet. Is there a way to define all those states and import them from a file rather than hand editing each one in the Definitions UI? Another example is I want to set large numbers of these states at appropriate points in processing. Is there any way to do so by just importing name value pairs from a file rather than hand editing each one and copy pasting from a spreadsheet built up accordingly. Thanks Very Much, Jim
  10. Hi all, I am wondering of there is a way to create something comparable to a"wait" resourcestate. Maybe by defining or monitoring the "waiting time" of a server. Thankyou in advance!
  11. Hello all, In my model, I have a pool of secondary resources representing Firms. Order entities with random amounts arrive from a source, targeting randomly selected firms. The amount in each Order entity is registered in a state value vector (called "FirmDemands" with a row for each firm) as the demand for its target firm. I would like to direct Product entities coming from a different source to the firms according to their present level of demands. I suppose I could use "Select from List" option, but how would I refer to that state value vector in the selection expression so that a product will be assigned to the firm with the highest demand at that time?
  12. In the batch that was created, I want to search the member entity with the lowest value for state variable "NumberOfRollContainers" and change its value to: <<TotalREQ" - 0.9 * "CapacityTrip">>, where "TotalREQ" and "CapacityTrip" are state variables of the parent entity. I am struggling with how to use the search step in this situation, so help is appreciated. Thanks in advance!
  13. Hello, If I have created a list state variable (The list just contains each day of the week. ie: "Sunday", "Monday", "Tuesday", etc...) and I want to assign a new value in a state assignment of the facility to a particular day within the list state variable how can I do this? It seems like I can only reference the List State Variable as a whole but I don't know how to assign values to the contents of the variable.... Thanks!
  14. Hello to everyone, How can I add final value to the result statistic for each server? Thank you in advance and best regards
  15. Hi, I'm working on an airport simulation, this is my first simulation, i have a transfer node that has one income link and two output links, so I would like to know if there is a way that depending on certain Entinty's boolean state variable, whe passing throught the tranfer node if the state is true set and specific outbound link and if it is false then set the outbound link rule by link weight.
  16. Hi, Is it possible to set the state variable of the parent entity in a batch equal to the sum of state variables of all member entities in the batch? Context of the case; a truck (parent) is loaded with x number of orders (members). These orders have a specific value for the state variable 'NumberOfRollContainers'. The truck has the state variable 'TotalRollContainers', which should equal the sum of the 'NumberOfRollContainers' in that batch. Kind regards, Christa
  17. I would like to reference state values associated with objects within a data table. For example, suppose I have a Data Table, call it Tab1, with an Object Reference column called Obj. The first entry in the object reference column is a resource called Res; thus, Tab1[1].Obj points to Res. How do I access the value of Res.CurrentCapacity using the table reference? To make this a little more complex, what if the state were a vector of integers? Thus, what I would like to reference would be something like Res.vector1[1].
  18. Hi, i want to set a state array to default. How do i do it ? For example, during the run i assign different states to some rows of the array. But then, it is necessary to set all rows to default (1 for example). Do i have to write a complete prozess for this or does a function exist? Best regards
  19. Hi, How can I check if an object refernce state is null? I tried "state.is.null" and "state == null" but both did not work. Thanks,
  20. In my model, I have a separator that will create 4 exact copies of the input entity. I would like to assign different values of states to each of these 4 copies. How can I do so? Thank you!
  21. I want to assign a state variable to the batch members of a parent entity, is this possible? the reason for this: I have 2 types of entities (passengers and bags), they separate, then go through different processes and then are combined again. but since the passenger entities have to be combined with "their own" bags, a state (or something else) should be assigned which can be referenced as "match expression" in the combiner. is this the right way of modeling this type of process? or should i do this another way?
  22. Hi, I want to have a source that creates entities according to a date. But also, I want each entity to carry some information like Code, Processing Time and Type. It is possible to do that? And After, how I can use the information that each entity carry? For example, Each entity has their own processing time (according to the table), how I can use that procesing time in a server? Thanks for your help!!!
  23. Hi all!, would you help me with this? I want to do a discrete simulation of the current situation in a Hospital in the inpatient unit. I have the data of one year of patients, (over 18,000 people) and I want to use that data in the simulation. That would make more easy to model the server processing times, while we will use the real server times and sequences that each patient had, instead to use probabilities and distributions for the sequence and server times respectively. So, I created a table where each row represent a patient with a sequence (which bed he was assigned due to his level of acuity) and the time that he spent in that bed before he was dispatched. The are more times involve, but we can focus in those parameters to have it more simple. So, the table have the patient name (entity) ,bed (sequence) and Length of Stay in the bed (server processing time). I don't know if is possible that when I create each entity, I can assign, based on that table, the sequence and the server processing time for each patient. How I can do that? Thanks for your time and help
  24. Is there any way to import a list of properties from excel? What if I have a model with a predetermined list of variables that rather than manually creating them one by one, I could simply import from excel?
  25. Hi everyone, I am working on a project that has more than 2,000 different arrival distributions. The distributions are all exponential, but they all change over time. To illustrate: suppose I am modeling 30 companies around the world, each company with a group of suppliers (or clients), each supplier (or client) with a group of parts (or orders) that will be arriving in my company to be processed. Each one of these parts coming from each supplier to each company (I will call it a combination) has its own distribution that changes over time. [this is an analogy to my problem] If I had only 1 company with a few suppliers and a few parts, the natural solution would be to use Rate Tables. This would be good because I want to investigate the impact of different Rate Scale Factors (increase or decrease of arrivals) on my key performance indicators. However, as I mentioned, I have more than 2,000 different distributions. So, my main question is: does anyone have a suggestion about how to create these arrivals in an efficient manner? I am assuming creating one source and one table for each possible combination would not be efficient, as it may make the model super heavy. I have thought about two different solutions (which I am not sure if it is good and, even worse, I do not know how to implement yet). So, recommendations to any materials, SimBits or tutorials that might provide more information about my ideas are really appreciated. #1) One idea was using an object inside an object in Simio. This may reduce at least a few combinations?! However, I do not know how to model objects inside objects in Simio. #2) Letting Simio auto-create all my servers and auto-fill the information using tables. This means that I would create one source for each combination. Although this may not be computationally efficient, at least I would not have to drag and drop each one of them. But again, I am new to this auto-create object tool and I do not know how to implement it. So, I really appreciate: - any ideas on how to solve my problem in an efficient way - materials that may teach me how to solve my problem using my idea #1 or #2. Another issue is that RateTables (as far as I know) cannot be imported and binded. So, how can I input all my 2,000 columns of arrival rate data in Simio? Otherwise, my solution #2 is really bad. I have also discussed the idea of grouping the arrivals together and using TableRowReferencing and discrete distributions ("mix") to reduce the number of possible combinations. However, the team I am working with does not think this is a good idea, since each distribution change over time in a different way. So, combining them may not be very accurate. Thanks!
