Now STEM allows you to share a working model within
your organisation, or even hand out such a model to a customer. It is possible
for non-licensees to vary some of the input assumptions and then re-run the
model to assess the impact on results: end-users can explore the dynamics of
the model and perform their own sensitivity tests, thus gaining much more
confidence in the model.
New in STEM 6.1 is the concept of a run-time model,
designed specifically for distribution to non-licensees. Such a model can be
re-run – in principle by anyone – using distributable run-time software
components that do not require a dongle. This vastly widens the scope of use of
the software: the only limitation on a run-time model is that its structure,
i.e., the set of elements and their names, cannot be changed.
The facility to create a run-time model, together with the
legal authority to re-distribute the run-time software components, is subject
to a premium distributable STEM (D-STEM) licence agreement with Implied Logic.
Although only a D-STEM user can export run-time models, all STEM
software components recognise and respect the semantics of such models; so
that, for example, a conventional STEM (C-STEM) licensee will be able to modify the assumptions of a run-time model
using the standard Editor without compromising its run-time status.
