Re #4, the GET DIRECT functions are new, so I haven't used them much, but my preliminary thinking is as follows: - GET DIRECT is more robust for general distribution, because it doesn't rely on the presence of Excel on the user's machine. - GET DIRECT also tends to be faster at startup, and more co...

Kim, thank you for the kind appraisal of my post. I would not have believed it but DT is - I am afraid - a big issue. I have enclosed a very simple model going just from year 0 to year 1 to make the differences obvious. We start out with 100 customers and they increase linearly to 110 by the end of ...

Hi fellow SD'ists, having gone through some considerable effort to dwelve into the realm of Kim Warren's strategic management dynamics, I have reemerged from my studies with mixed feelings: On the one hand Kim has managed to (finally) convince me that SD can and should be useful to "ordinary&qu...

Thank you, Tom - although I was aware of those possibilities. In the case of many possibilities to achieve one thing or the other one wonders if it all is just a question of personal style. Or are there "reasonable" considerations guiding the way: 1. For one thing I am still at a loss with...

Tony, I just came upon another question with regard to the use of reference modes and lookups: I wanted to send a packaged model and while testing this I noticed that I cannot change any data variables in the Model Reader. But that means a serious handicap as I wanted to give a customer a way of cre...

Thank you, Tony. Sometimes it is the "easy solutions" that fail to be noted.

Thomas, try Kim Warren's Strategic Management Dynamics (2008). If you are up to German, there is also a recent dissertation out there about Value Drivers which very explicitly touches the different strategic views in the literature with some reference to the BSC as well: Kunath, Oliver (2009): Syste...

Hi everyone, I wanted to use reference modes to create exogenous data driving the model. For some purposes I need a step function input (e.g. :HOLD BACKWARD: or :LOOK FORWARD:). Instead of reading in data from a spreadsheet file I tried to use GET DATA BETWEEN TIMES(data var,time,-1) to keep the val...

I have found the books by Hartmut Bossel (available in English) a great addition to the standard Anglo-Saxon texts out there. His basic introduction to systems and modeling is very rigorous and gives a good intro into modeling in general. Quite valueable is the inclusion of a chapter on the mathemat...
