  1. 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?

  2. Hi Folks, We have a data driven model where entities require a value from a table with n named columns. For example, consider the column names might be "Group1", "Group2", and "Group3". For each randomly selected entity classification based on a random row for example, we wish to randomly select which column to grab a numeric value for that type entity. Each Type has a unique distribution of amounts in the table. Suppose an entity has a string state called MyGroup, and I set that value. For example ModelEntity.MyGroup could be set to "Group1". Is there a way to use that name as a reference to the named column in a data table? I was thinking something like ModelEntity.MyValue set to MyTable.(ModelEntity.MyGroup) would be nice if it worked, but it does not. Is there any way to use that string state value as a reference to a named column in a desired table? Thanks So Much For Any KindThoughts On This, Jim
  3. Hi! I would like to use a Create Step and create, e.g. two entities. But when I'll create them, i want to assign different state values, e.g. Entity1: 20 and Entity2: 50. Therefore, is there a way to assign different values to the entities?
  4. 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
  5. Hey everyone, I'm having some troubles with my model. I'm using the create step in a process to create entities different from the original one. The thing is, I need to assign the state variables from the original entity to the new entities, but since the those are attached to the original entity, when I use an assign step on the created entities, I am not able to do that. Is there any expression to get the state variables from the original entity, or any other way to do it?
  6. 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
  7. 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!
  8. 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?
  9. 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!
  10. Hello to everyone, How can I add final value to the result statistic for each server? Thank you in advance and best regards
  11. 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.
  12. Hi, I would like to add a table state property to set shipping dates of the introduction tutorial http://simio.talentlms.com/catalog/info/id:121. But I cannot find the complete state tab as shown in the video / attached picture "stateTab.png" in my version 11 of simio. I introduced a standard property of type state "StatePropertyIntroduced.png" ... but then i cannot set the Date/Time when shipping my products with "Orders.ShipDate = TimeNow" in "timeNow.png". Any Idea how to solve the problem? Cheers Ralf
  13. Hi all, hope you're doin' well. I am new to Simio, last time I used it was 2016 for less than 3 months. I was trying to make a reference for the processing time in the data table as follows: 1. I have 2 different entity types (A & B e.g.) 2. I created a binary state (0 vs 1) [ note that I created the this state] I wanna create a data table for the processing time (for a server) covering all the 4 possibilities: A0 == [3 mins] A1== [4 mins] B0==[5 mins] B1 == [6 mins] I appreciate your help guys. Abdul
  14. 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
  15. 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?
  16. 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!!!
  17. 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
  18. 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?
  19. 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!
  20. I would like to refer to the BicycleAssembly Simio Simbit as I'm using it as a reference to set up my own model. As I set the Initialization step of my model, I read the Orders table row by row, using a global variable called CurrentRowNumber. However, when an order entity is created, I would like to keep track of the row in the Orders table that entity is created from with a model-entity level state variable. However, I'm not sure how to do. I cannot just assign the value of this ModelEntity.State = GlobalCurrentRowNumber as the GlobalCurrentRowNumber continuously changes as the simulation runs. May I have some suggestion as to how to do so? Thank you
  21. 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!
  22. In the source of my model, I would like to generate arrival events by looking through row by row of a given table. However, I only want to create the 2nd arrival event when all the entities of the created by the first arrival event has moved beyond a certain point, where Globalstatevalue = 0. So in my process flow, I did something like this:When the globalstatevalue = 0, I want to go to the next row of my table and generate the 2nd arrival. I did this my fire an event The setting at my source: Arrival Mode: On event Triggering Event Name: name of event that I fired in the process flow. I managed to get the initial arrival to make sure that the Globalstatevalue = 0. condition is reached. However, the 2nd event is not triggerd at all and the CurrentRowNumber is not incremented as well. May I have some advice please? Thank you
  23. Hi, I would like to ask on the Bicycle Assembly SIMIO example. In the example, under the Manufacturing Orders table, they have created an integer state variable called RowNumber, which I thought could have been created under "States" in the "Definitions" tab. However, when I went there to find the state variable RowNumber, I could not find it inside there. Hence, may I know how the state variable was created? Thank you!
  24. Hi, How can I change a state variable of a flow entity? For example, I want to change the color (i.e. picture state) of the entity based on the flow connector that the entity enters. Any suggestions how to do that (apart from converting the flow entity into a discrete entity and then back to a flow entity)? Especially, because flow connectors do not have Add-On processes. Any ideas are appreciated. I have already reviewed the SimBits for flow library and could not figure out. Thanks!
  25. Dear All, New to Simio and struggling with the following problem. I would like to model an entity to exit a server at its assigned time as a state variable for now, I know this: Every entity is assigned before exiting the source with a state variable (pick-up time): TimeNow + random value between 1 -5 I want to use this state variable to decide with an add-on process if the server can finish processing; TimeNow == pick-up time if not, the server keeps processing. In other words, the processing time of the server depends on the state variable of each individual entity. Hope someone has tips or tricks to solve this!
