sending items with different contexts

Hi all
i want to send item types to different ports with different percentages.
For example i have a rack with 4 itemtypes.The rack is connected to 4 queues.

Each itemtypes goes to queues with percentages like this.

itemtype 1 25 30 20 25
itemtype 2 20 20 30 30
itemtype 3 40 20 15 15
itemtype 4 15 25 25 35

How can i realize this?

Hello Sagar,

the function is dempirical(table[object node/string/number], random stream). The function gives a value you set in the second column of the empirical table. It is the port to send to.
You choose in the Send To-function from the pick list "cases by value".
Instead of the static port you set your descret empirical distribution.
The Random stream is unique to the itemtype and the flexsim object and the Send To function. You use this random stream only once in your model. The random stream is doing its job, because it is randomly to this single decision point.

Hello,

another approch with the same result, if some condition applies.
These are that the table names contain numbers in ascending order and these numbers can be computed directly from the itemtype values.

/**dempirical port different by itemtype*/
int index = getitemtype(item);
string s_index = numtostring(index); // num itemtype as a string
int stream = 11 + index;// unique random stream between 0..99 in the model
string s_stream = numtostring(stream);// num stream as a string
string s_table = concat("GlobalTable",s_index);// Name of the global table: GlobalTable2
string distribution = concat("dempirical(",strquote(s_table),",",s_stream,")");// combine the strings to a command: dempirical("GlobalTable1",12)
pr();
pt(distribution);// write command string to output console, just a test
return executestring(distribution);
