Yes, the external table has all the needed info. But I want to be flexible in using those tables for modelling production processes. Meaning - for modelling one production process I might needed 5 workstations, whereas when modelling another process I might need only 2. And my idea is when the model runs, based on the info in the table the model dynamically creates the needed number of workstations.
A work-around is to create a model with N workstations, where N is sufficiently large to cover potential needs of workstations. Some years ago I was using Awesim (guess you know that system based on SLAM). In Awesim if an entity needed a resource and that resource was not existing, the system will automatically create and instance of the Resource node, thus allowing for dynamic creation of resources in the model. All this was packed in the sub-network functionality of Awesim.
Anyway - guess the work-around approach will do me the job I need.
Thanks for your time Dave!
