tank can easily be handled by understanding that it does have batch

Note - S88 is very
flexible, but many practitioners seem to follow an approach focused on the
Equipment Modules, with phases running in them.
There is another equally valid
one where phases run in the Unit. ControlDraw can handle either approach,
in fact it can have both in the same model.
You can download a ControlDraw
Model demonstrating this from the Download
page. This model contains a Process Cell and two Units, based on many examples
on the web.
Here are the Typical EM based PDF and
Centric PDF exports.

And one to make you think. OK, it's from a Web company but
it rings bells
"Visual design first, programming second. The more traditional process is starting from the abstract (documentation, diagrams, charts, etc.), coding a skeleton app, and then homing in on the real by finishing it up with an interface. We think thats backwards."
Getting Real, Step 1: No Functional Spec
"Dont write a functional specifications document. Why? Well,
theres nothing functional about a functional specifications document."
Of course that is not true with a ControlDraw FS.
And from another non S88 source - if you are having problem
modelling something it may be a Wicked
Or you just don't know how to tame it.
In such cases ControlDraw Consultants may well be able to help.
