I disagree, Brian. I _need_ discussion of the deeper differences and
similarities between SD and other methodologies to understand better
whats going on. Jims contribution emphasises the distinction of
resources vs. behaviour, and this distinction is a new one to me. I find
it reminiscent of the distinction between the more data-centred
entity-relationship modelling and the more behaviour-centred
object-oriented modelling. Is there any similarity between these two
juxtapositions? (Im not at all familiar with discrete-event modelling,
although it sounds similar to frame-based modelling.)
