  1. You can still use your various 'lists' of servers in SetA, SetB, etc.). You still will need a Sequence table with the Sequence Destination property column. This tells Simio within the Sequence table the destination to route. So, within your Facility window, add a TRANSFERNODE before each 'set' of areas, let's say named SetA, SetB, SetC, SetD. Then, within the TransferNode, use the 'Select From List' for Entity Destination Type property and specify the appropriate list (SetAList, etc.). Then, within the Sequence table, route to the TRANSFERNODE that uses the particular list - so in the above, you would have within your Sequence table, SetA, SetB, SetC, SetD and Input@Sink. Within each of your Server's output nodes, specify Entity Destination Type as 'By Sequence'. You may wish to look at the example named SchedulingDiscretePartProduction to see the layout of the nodes within each section and the Routings table used (this is a much larger example, but the concept of the nodes, the sequence table and in that case a RoutingDestinations table (which is like a node list in Lists) is basically the same.
  2. Check to make sure you are connected to the internet. Based on typing in Dallas, TX and selecting OK, you should get the pull down list of other alternatives as well (or type in a specific street address). What Simio sprint version are you currently using? The below is what appears for me when using Dallas, TX (after I first went there, then typed in location again, got the following pull down list).
  3. Within each of the Source objects, you would specify (within the output node of the Source) that a worker is required to transport the entity(s) to the next node. The decision making of the worker is then handled by the worker itself. The worker has several decision making options - first of all, for transporting, the worker has Transport Logic properties, one of which is the Task Selection Strategy property, which can be set to First In Queue, Largest/Smallest Distance or Largest/Smallest Priority. In addition to that, under the Worker's Add-On Process Triggers properties, you have the Evaluating Transport Request process that can be used to accept or reject any transport request. You can add custom logic, a distribution, etc. within a Decide step in that called process and simply then accept (Token.ReturnValue == True) or reject (Token.ReturnValue == False) a request (which is the first in the allocation queue, as ranked as noted above). You can use the requesting entity location within the decision logic as well.
  4. Please either attach a copy of the model you are referring to with this post or send the model with description of problem to support@simio.com. Thank you.
  5. You cannot control the entity id number yourself, that's internally controlled. However, you can use a model state variable / model entity state variable to do something similar with your own count, based on the entities generated. When an entity is created, simply assign the model state variable == model state variable + 1. Then assign ModelEntity state variable to the model state variable.

    tagging Entity

    Yes, let's say your entity is created using an Orders table, where the entity has a 'row' in the table associated with it (with arrival time and other data, presumably the customer ID as you mentioned from the excel file). Then, within the ModelEntity object, find the Display Name property (under Advanced Options). The table name/column name can be referenced within the Display Name (and then the Display Name, ModelEntity.DisplayName) referenced from the Dynamic Label Text property - see the SchedulingBicycleAssembly example under Support ribbon, Examples. Then, when the entity moves around the maintenance shop / manufacturing floor, etc., it will be labelled with the information associated with the entity (ID) from the table.
  7. One option would be to put the 2 (or more) workers in a 'List' of workers and simply select from that list, and use the Number of Objects property (under Advanced Options) set to 2 (or the number of workers in the list that are needed. Workers can be placed on multiple lists. Another option would be a more complex table based approach. See the UsingRelationalTablesToDefineTaskResourceLists SimBit for an example.
  8. Based on your description, you could add a new State variable to the ModelEntity. This state could then be used to group into their separate buses. See the SimBit named 'LogicBasedOnEntityState' for more information on adding a state variable to the entity. I'm not sure the entities need to be batched, but could be sent in different directions based on their new state variable (BusNumber, as an example, assigned to 1 or 2). If they go on a completely different 'routing', the ModelEntity.BusNumber could then be used in a Decide step within a process that would assign a sequence table to each - using a SetRow step. See the 'ChooseAlternateSequence' SimBit for an example of using the SetRow step.
  9. The various resource type objects, such as Server, Combiner, Resource, etc. as well as moveable resources, such as Workers and Vehicles have Resource States that are automatically assigned by Simio. See the List States page in Simio for a listing of the resource states for each object. You can evaluate the state by using the ResourceName.ResourceState in an expression, such as in a Decide step - Server1.ResourceState == 3. These resource states can also easily be viewed by clicking on the object itself and going to the Active Symbol section of the Symbols ribbon to display the animation symbol and listing of the various states and their associated numbers.
  10. What are you trying to do with the Search? How is the process that contains the search triggered? If you can provide either the model or some details of what you are attempting to do, it would be helpful.
  11. The easiest way to do this dynamically is to use the Dynamic Selection Rule property on the Server (or other object, such as Combiner, Worker, etc.). You can use the 'Standard Dispatching Rule' option for that property to then include a Dispatching Rule, such as FirstInQueue, LeastSetupTime, EarliestDueDate, LargestPriorityValue, etc. This allows you to specify a TieBreak Rule as well. Using the dynamic selection will not determine which entity will be selected from the queue until the resource (object) has released an entity and is available.
  12. Work Schedules can also be applied to other Fixed objects, such as Server, Combiner, Separator, as well as stationary resources. I suppose the question would be - how do you generate your entities (arrival table, time varying arrivals, interarrival rates, etc.) and what would you like to happen to entities when the 'model' is off shift -- do you stop creating entities/orders - what happens to in progress materials (do they clear out like a bank at end of day or stay in system like a mfg plant.
  13. In addition, we've added the capability to have various Simio objects 'automatically' created in their physical x/y/z locations from data tables. For an example of this, see the SchedulingDiscretePartProduction.spfx example (Support ribbon / Examples) and review the Resources data table. A column of type 'Object Type' of Object Reference specifies the type of object to create. An 'Object Type' column, Resource Name, then uses that 'ObjectType' column as its property ObjectType with the Default Value Instantiation set to 'AutoCreateInstance'. The XLocation / ZLocation columns are then used within the Initial Object Offset properties. Moving the node (or whatever object) within the Facility window then changes the XLocation/ZLocation values. This table automatically generated the Facility window contents.
  14. We have a number of SimBits that include processing data within tables - perhaps search Sample SimBit Solutions (Support Ribbon) and look under the Data Tables section for multiple examples and see what may be similar to what you are trying to do.
  15. We have a SimBit titled 'SelectServerWithShortestLine' in which there are 3 servers to select between and the output node for the Source provides the logic for the selection. The Server input nodes are put into a NodeList named 'Servers'. This list is then used to select between the members based on a Selection Goal 'SmallestValue' based on the expression 'Candidate.Node.AssociatedStationLoad'. The associated station 'load' is defined as the sum of current entities en route to the node intending to enter the stations, plus the current entities already arrived to the node but still waiting to enter the stations, plus the current entities occupying the stations. This can be used whether or not the capacity of the input buffers is specified for the Servers.
