I have a model in simevents where, I want to include the entity attribute: age. Age must be signal port and must be created as a value vector where the age values will be [10-19, 20-29, 30-39,...and so on until 100]. The value vector will then be combined with a probability vector, in order to create an event based random number. My question is how can I set a value vector that will permit value intervals as the above. Thank you in advance!
