Hi, I use System Dynamics (SD) models to engage stakeholders (those of little background or interest in the necessary math but are the policy-makers, hold the purse strings, and hold the biases as the system experts). I believe SD is probably the most intuitive modeling platform to build CT models but there are many constraints that Kepler/Ptolemy could rectify. I am asking my question under the notion that stakeholders will have trouble "seeing" their system with the Ptolemy mapping/icon modeling layer. Models are probably useless in the practical world if stakeholders cannot "buy into" the model. To many stakeholders, modeling is intellectual voodoo and there is a lack of trust (e.g. you can prove anything to the layperson with the wrong statistics model) that must be overcome and SD is a tool that enables this.
What would it take to encourage Ptolemy developers to build a SD-like layer of system modeling (using icons of stock and flows and also keep the converters and look-up tables or graphs) interfaced with the more mathematically versatile modeling of ptolemy. For example the SD stock is the integration thus a link to an integrator actor (?). A package of SD-specific actors?
