  1. I build my simulation model with some troubles, some adittional help would be nice! I am having problems with tables. I want to do a arrival table ( as has been said) but fails to get the results. Since I have two entities I build a two node lists for two rounting groups ( for each entity) and in the table with I specifiy each entity interarrival time ( for excercise pourpuce) with which rounting group goes to.... I mean If I set a table with arrival times I don't get statistic results like ultilization and so on... and do I have to set an outputsource any more specific ( If I did this in tables already?) How can I get table with interarrival time and rounting group? Do I have to bind this to? So to be more clear: how to set tables in arrivals or interarrival time for ( each) entity coming in one source and in which rounting group each entity goes to? thank you in advance! beautysalon - Kopija.spfx
  2. Well the case with this is: I am doing analysis of beauty salon where costumers ( entities) are scheduled. It's not random neither deterministic ( I think) system. Working on calulation of the server 8 or payment time or utilization of the server. I will try this and if I didn't get anything or it still have problems, I will type here. thanks!
  3. ''When you say you have "real data" do you mean that you have samples of processing time? If so, from that you would normally fit a distribution our use a table-based Input Parameter to draw from.'' By real data I mean for every entity I have excact time when they entered the system then for each of the costumer ( or entity) where and when they went ( to each server) ; and specific time how much time specific server worked for each entity ( or costumer), and last; processing time ( payment) for each costumer in server 8. So as you can see all parameters or ( interarrival time or specific time when entity goes in to system, and specific time that entetiy spend in servers (1-7) and time for payment each entity on server 8 ). I don't know how to select a distribution that fits my system other than use a table based input parameter as you said. Is there other way around to select distribution that fits, how can I get this other than put table with specific values? what is the best choice here? ''You say that Servers 1-4 are identical and Servers 5-7 are identical. It might be easiest to model that as ServerA of capacity 4 and ServerB of capacity 3. '' it seems like this is the easiest way yes! The thing is: since system isn't FIFO or LIFO, must I (?) ( as you said ) put selection rule source output ( to see where the entity goes next to which server) to determine which entity goes to which server , So I can still use Server A for capacity 4 and server B of capacity 3? This confuse me, since sistem isn't 100% fifo neither lifo - is this important or not? I mean the most important parameter is utilization of server 8 ( since this is pyhsical payment, I would like to get how much % of their time is wasted with their decision to have pyhsical payment) And I don't know if for utilization ( server 8 ) is important or not.... thank you !
  4. Hey I am new member and a new user of simio! English is my second language so bear with me, great product btw! I would like to ask some questions about simulation that is unknown for me.... for example ( in my case) I have a real time between costumers, real times for each specific server, and server 8 ( that costumers all go through).... So I have a make a simulation. situation of this specific queueing is: I have 1 source and 7 servers ( the first 4 are equal or Equivalent and the server 5,6,7 are equal). MY question is following: -Can I make a one DATA table for servers 1-4 ( they are equvalent) and another for 5,6,7 ? Or do I have to create 7 data tables ( for each on own)?? - And there isn't real FIFO neither LIFO ranking rule, there is specific, And I don'0t know how to adress this to add specific ranking rule for my case - Do I have to make 2 model enteties cuz there are 2 differnt servers for this case? My primary goal is utilization of server 8! is ranking important or it doesn't matter? thank you very much!
