EVERY GOOD REGULATOR OF A SYSTEM MUST BE A MODEL

The design of a complex regulator often includes the making of a model of the system to be regulated. The making of such a model has hitherto been regarded as optional, as merely one of many possible ways.

ABSTRACT
The Viable System Model (VSM) is recursive and helps explaining the general production management model of the ERP system. The recursion level explains the development
starting from warehouse management to Material Requirement Planning (MRP), to Manufactory Requirement Planning (MRPII), to Enterprise Resources Planning (ERP), and
to Supply Chain Management (SCM).
In each recursion level, the emergent concepts helps explaining the discovery of the two categories of demand: independent demand and dependent demand, the feedback concept
helps explaining the closed cycles in ERP, the local, future and total environment concept helps explaining the interactions between the market and the Production System and the
Law of requisite variety helps to manage complexity.

Cybernetics – start here guide

[dhcs: May 28, 2010 | please note: this piece was originally put in place for a predecessor weblog (http://cep.weblogger.com) as “Cybernetics – start here guide” and the original  page was still  under construction at the time that this new website was started…. in this new incarnation it is still,  unfortunately,  essentially a collection of “signposts”  rather than a travel guide, however annotations will be added over time to turn it into (a)  a true guide to the field and then onwards towards (b) the foundation of a “learning machine”The original concept of  the ‘start here guide’ will be replaced by a series of new posts on this site over the next several weeks]

“In 1948, Norbert Wiener pondered a new science in his classic book Cybernetics, one that flirted with the “boundary regions of science.” Sustainability today occupies a similar state, but the concept is used more as a policy guide and buzzword than as a true science.”

  • GAO: urgent policy concerns for transition/new administration – Many of the urgent policy concerns identified here are critical and time sensitive and require prioritized federal action. They are issues that require a focus from the transition team and new administration because if they are not dealt with, they could have great implications for life, well being, or the confidence of citizens in government, or because they have key quickly approaching dates where a decision must be made or actions taken. Consequently, these issues are not necessarily the most important issues in the long term, but rather those that must be dealt with immediately.

Designing Freedom & The Purpose of Education

Stafford Beer 1926 – 2002

If, as will become the dominant theme of this blog, the Purpose of a System is What it Does ( POSIWID) what does it mean to mankind that so many of our systems appear broken to even unseasoned observers?

Stafford Beer of course had a lot to say on this subject in his many works but one example that often haunts me comes from his work of prose Chronicles of Wizard Prang.

in Pharyngula [Evolution, development, and random biological ejaculations from a godless liberal] PZ Myers writes about a recent press release from Princeton:
“Unfortunately, the puff piece writer and the scientists involved seem incapable of actually explaining what they found, which makes me extremely suspicious.
….
Anyway, I’ll be looking for the paper. My bet would be that it says nothing like the claims made for it by the press release, or that it will be an embarrassing error of interpretation by the authors.:
The target of his disbelief was also discussed in a recent thread on friendfeed:
Geoff Schultz (friend of Louis Gray) posted a link

Breadcrumbs for November 13th to 21:29

These are my links for November 13th from 21:06 to 21:29:

  • Happiness as the Ultimate Goal of Cybernetics – There are two basic problems to be solved — “What has caused these problems and how can they be solved?” and, “If solutions do exist, are they compatible with humankind’s happiness?”
    Both of these problems must be analyzed based upon the careful analysis of human nature. This paper first discusses the problem of what aspect of human nature is relevant to the ceaseless increase of energy use and how such aspects can be utilized to evade the problem. The analysis of the human feeling of happiness will then be presented to examine if the life of decreased use of energy is compatible with the human nature.
