  1. Off Shift Rule is a List Property. The list is inside the server, but when referencing it, you need to create a list on the main model too. First Create a string list with 2 rows SuspendProcessing; FinishWorkAlreadyStarted (in that order). Then create a table with a List Column (in Standard Property). Set the List Name to the List you just Created.
  2. If you mean that an entity should not advance to the next location unless it is available: Try using Node Lists when routing entities to the next location. Lists automatically block the entity from moving forward if the destination server is not available. 1. Create a node list in Definitions>Lists 2. Set the input and output buffers to 0 on your servers 3. On the output nodes, set Entity destination type to "Select From List" and choose the node list. If you mean you have a group entities that are processing at different servers and none in that group can advance until all
  3. We will add this to the user request list. A possible work around is to use Entities instead of vehicle and use the Travel step to move to places in freespace and use the Batch step to pickup a different entity.
  4. If you batch the Entities together, you can Search the ModelEntity.MemberBatch queue. Then sum the lead time for each member entity and the parent entity to get the total lead time.
  5. If you want to change the capacity of the server at Initialization, create a control property and reference this control value on the Capacity property of each Server. If you want to change the server capacity during the run Assign the variable ServerName.CurrentCapacity the new value. If all workers are always working at the same server, you may want to just batch the orders together then seize the correct number workers (actually, you wouldn't even need to increase the number workers). If one of the above solutions does not help, please attach a model to clarify what you are trying to
  6. The problem is that when the Vehicle is not moving, the Vehicle does not seize itself, so it is not one of its Seized Resources. The Second Search will not find the Vehicle. If the vehicle is the only thing that seizes the Grutier and IAccrocheur, then you don't need the 2nd Search. The ResourceOwner of the Worker is the Vehicle, so you don't need to search the Vehicle's Seized Resources. If entities can also seize the workers, then split logic for vehicle seize and entity seize.
  7. Hi, The Decide step is looking a the variable ModelEntity.CustWaitTime but that state is never assigned a value so it is always False. Also this state is a DateTime state, but should probably be a Real State instead with the Units of Time. Assign the state a value or just use 'TimeNow - ModelEntity.TimeCreated > (5/60)' expression. To use a Tally as a count, I would recommend just using the Number Observations result (automatically recorded) and either set the Expression to '1' or actually record something like 'Run.TimeNow - ModelEntity.TimeCreated'. You cannot use the TallySt
  8. 1. If you look at the results in the pivot grid for your vehicle, you will see that the Resource State Time Offshift Busy is very high. This means your Vehicles are still processing (utilized) after they went offshift. Scheduled utilization is based on how long the Resource is utilized vs how long the Resource is scheduled to be onshift. By default, Resources finish processing their current entity before going offshift, during this in bewtween time it is a state called OffshiftBusy. You have to put additional logic if you want something different to occur. Look into the Interrupt or Suspe
  9. ExcelRead only reads String and Numeric values. These string values cannot be applied to an object type state. However, you can bind your Excel file to our Tables and import your data in that way. Attached is model that demonstrates this. First, bind the Excel file to a Data table: Create a data Table (no columns), Bind to Excel file, Change Column Type to Object>Node, and Import data. Check out Help Topic Importing and Binding To Tables for more info on binding. Import can be set to Automatic (default) or Manual. Then modify your process logic to use a SetRow step instead of ExcelRe
  10. Tally Statistics are more for recording the same numeric expression throughout the simulation. You should use the Write or ExcelWrite steps under User Defined steps in the Processes tab. The Write step write data to a csv file and is usually faster than writing to an Excel file with ExcelWrite. Check out the SimBits Writing To A File and Excel Read Write. You can record numeric and string value. The Date expression should look like 'String.FromDateTime( TimeNow, "MM/dd/yyyy HH:mm:ss")', and then Excel will convert the string to a date if need be. For the Entity ID the expression would be
  11. If you are searching a table, then there is no candidate. The expression should look like 'TableName.ColumnName==ModelEntity.StateVariable' . The row for which this expression is true, is the row that is references by the Found branch.
  12. The Server knows that there are 20 units on the pallet, but it cannot access the individual processing times for each product without using process logic. Use a Search step to find all the units on the pallet and add the individual processing times to a state on the pallet, then use this state variable as the processing time on the server. To do this, use a process on the Before Processing trigger. Add a Search step to search the QueueState 'ModelEntity.BatchMembers' (and set the Limit property to 'Infinity'). Create 1 state variable on the model - TempStateName, and 1 on the ModelEntit
  13. To change the states of Entities riding on a Transporter, use a Search step to find the Entities then use the Assigns the on the found branch. Use the following settings on the Search step: Collection Type - 'QueueState', Queue State Name - 'Vehicle.RideStation.Contents', and Limit - 'Infinity'.
  14. One way is to change a variable when a Worker is seized, and check that variable in the Worker_EvaluatingSeizeRequest process. If the variable is 1, accept the request, but if it is 0, reject the request because the Worker still needs to transport the other entity. In the attached model, the variable Worker.priority is changed to 0 when the worker is seized and back to 1 when the entity is unloaded in process Worker_Unloaded. Worker_EvaluatingSeizeRequest checks the value of Worker.Priority to accept/reject seize request. In sprint 7.123, you can reserve the Worker so it can't be sei
  15. Try using the Rate Scale Factor on the Source for Rate Table. The Rate Scale Factor can be used to increase or decrease the values in the Rate Table by a given amount. For example, to increase the Rate Table values by 50%, the Rate Scale Factor should be 1.5. Set the Rate Table Factor as a state variable that changes everyday.
