  1. Hello, if I use a normal distribution for the processing time of a server, I often get negative values. (How) can I avoid this? Regards
  2. Thanks, I've found this already. But I need (similar to the TimeInSystem Statistic) the (average, minimum, maximum) waiting time for each entity type in the model. Is there any possibility to get this number?
  3. hello, is there any number in the simulation results which returns the average waiting time for each entity? If not how can I implement this situation easily? Thanks! Regards, Nadine
  4. Thanks a lot! Now I understand that differences. But it's not yet clear to me when I have to use the instance name (defaultEntity) to refer on any state or property. Could you pls give me an example for this case? Regards, Nadine
  5. Hello, could you please explain the difference between entity, model entity and the defaultEntity and give me examples where I have to use which reference in an expression? Thanks a lot! Regards Nadine
  6. hello, could you please explain me how simio calculates the different types of costs for my resources? I have 5 secondary resources which are allocated to diffrent servers. I attached a table with idle and usage cost charged and the different types of costs. I don't understand how the costs are calculated or made up in this case. I think the costs and the times don't fit. Could you please help me? Thanks for helping! Best regards Nadine Times_Costs.xlsx
  7. Now I have another problem: I use the ExcelWrite step to store information about the current entity (Name, Time etc.) in a server. The step is triggered by an add-on-process 'processing'. I also want to store the resource which is seized by the entity at this time. My resources are secondary resources in the servers. Which expression do I have to use? I tried to do this with 'ModelEntity.SeizedResource' but I think this isn't right because in the corresponding column there are only '2' in each row. Regards Nadine
  8. Thank you! I managed to solve my problems. The ExcelWrite is really great
  9. Hey, I want to store informations for each entity in a data table or data sheet. The resulting table should contain a list of all entities and for example the corresponding throughput times. In the ideal case average an maximum values are also given in the table. Which posibilities are there in Simio? Regards Nadine
  10. Hey, I want to store information of each entity in a data table with tally statistics. I looked at the TallyStatisticsInTables-SimBit and implemented all steps in my model. My Tally Step stores the current NumberInSystem of my entities. So I created a data table with one column 'Entities_NumberInSystem' (Type Tally Statistics) and a TallyStatistic named 'EntitiesInSystem' which I referenced in the first row of my data table. The Tally Statistic Name in the Tally Step is set to 'Table1.Entities_NumberInSystem'. When I want to simulate my model I always get an error message: 'Error evaluating the value of property 'Tally Statistic Name'. Invalid data table reference Table 1.' Where is the problem? Could you please help me?
  11. I'm already SI! Could you please post the link or the name of this topic? Thanks a lot for your answers!
  12. Hello, my resources follow a work schedule, they work from 7-23. Now I want them to continue working after 23 if there are entities left in the system. When these entities are disposed my resources can stop. Is there any possibility to do so? Regards Nadine
  13. Hello, i want to model time varying arrival rates for my entities. If I choose rate tables I can't select random arrival rates. Is there any possibility to do so? Regards Nadine
  14. Thank you, I used "is" and i works very well
