Re: Accreditation and Certification for System Dynamics: Mee

Thanks Etiënne.

I will add that isee systems is looking at adding a Certification program to fill this void and have been in talks both with earlier incarnations of your committee and WPI around this idea. We are starting with a Systems Thinking certificate this fall, but plan to add SD soon.

Re: Incorrect floating-point numbers in sample model

The intention of IEEE 754 compatibility was for the behavior of operations, not the format of floating point numbers as text. The spec clearly shows the BNF for floating point numbers in Section 3.2.1, along with examples. Leading decimals are allowed.

Re: Handling model variables not mentioned in a view

The problem is that there are indeed popular SD modeling packages that do not require that all variables appear in a view. To be compatible with them, this clause is necessary (but you are right that the use of XMILE-compliant is confusing). In such packages, those variables do not appear in any vie...

Re: Back to basics?

Hi Magne, The <i>module</i> object in iThink is, as Bob says, just a vanilla container for a submodel. It has no equation and is not integrated, but its name is important as it qualifies names of variables in that submodel when they are used outside that submodel. The module object has inputs and ou...
