Fellow SDers,

I am posting a query for a fellow scientist in the Canadian Department of
National Defence who would like to know of any references on SD applied
to the human mind and cognitive ability under stress similar to Commanders
in Combat.

Thank you in advance,

I suggest reading,

Morecroft, J. 1983. "System dynamics: portraying bounded rationality"
Intl Journal of Mgmt Science 11(2), 131--42.

Bounded rationality encompasses the notion that decision makers in the
real world base their decisions on few and certain data as opposed to
all possible and available data. The higher the stress, the fewer
and more certain the data. The notion seems applicable, and the
article is very well written.

Ivan,

This is a very interesting topic and an exceedingly important one (Ive
worked on defence problems using SD for years and this is a crucial issue).

Put too simply, the crux of the matter is what sort of balance of investment
helps commanders (and their staffs) to win wars. Information overload is a
big risk but there is an implicit trap in the very words Command and Control
in that they almost say that any addition to C2 systems is bound to be a
good thing. The classic case of that is a Flash priority telex in a NATO
exercise which, when laid out on the corridor proved to be 16 metres long!!!

I have a model of work processing in C2 (European Journal of Operational
Research 28 (1987) 27-43 - based on NATO work) which is a bit of a start. It
only deals with the idea that standard reporting procedures between a
network of HQ (which can be at any level of command it doesnt have to be
Alliance) generate certain volume of work and assesses whether or not that
can be carried out. One variant is when the commander wants to implement a
new option which adds to the workload and the model gives about 4 measures
of what effect that ahs on the C2 system and how long it takes to have an
effect.

Id very much like to extend that model (or build a new one)

Hmm. Human mind? Have you looked at perceptual control theory? I
dont know if its been applied to cognitive ability under stress, but
it might be worth a glance.

You may also want to look at "Playing the Maintenance Game: How Mental
Models Drive Organizational Decisions." Its chapter five from the book
"Debating Rationality," by Carroll, Sterman, and Marcus.
Cornell University. 1998.
