LIMITATIONS OF
STRUCTURED MODELING
“Why isn’t t structured modeling (or equivalent) used as a matter of course in
OR/MS modeling endeavors?”
• Endogenous factors:
– No graph-driven implementation
– Static vs. dynamic representations
– Complexity of indexing semantics
• Exogenous factors:
– Math as legal tender: OR analysts are overwhelmingly mathematicians
– Overhead of conceptual modeling: Even database analysts resist conceptual c
modeling
– Models don’t t command the same respect as data
– UML has become the lingua franca of conceptual modeling
– Internet and distributed computing
• (“It can be done” & “It should be done”) ) ~=> (“It(
will be done”)
