Hi there, As background I'm new to Java and Anylogic; I currently produce various models in Excel VBA and want to move towards utilising Anylogic where appropriate - at least at first to investigate relative speed (VBA is getting slower as model sophistication increases - even with all processing achieved in arrays; I've run out of tricks). I am using Anylogic advanced. My main issue is finding a way to import individual agent attributes when initialised. Ideally they will come from Excel where I can pre-process/store parameters such as their potential locations relative to each other using PCA (principle components analysis) or preferences (or for conjoint analysis preferences utilitites). It is important that I use specific consumer attributes as one of the outputs is probability of individual choices of product cross-tabbed by segments/demographics. Can you point me towards the Anylogic commands that allow importing from a line in a text or Excel file? If I've overlooked an example that does this then pointing me at this should be enough - if not then this would be a great example to add as a proof of concept/learning. By the way for people coming to Java not from C++ I would not recommend Thinking in Java by Bruce Eckel. I managed to get about 100 pages in before the references to C++ began to get in the way of my understanding. I have made much more progress with Head First Java by Kathy Sierra and Bert Bates (300 pages in so far - it doesn't use C++ as the reference point too many times!). Regards, Andrew
