It seems like we are talking about the utilization of "fuzzy logic", that gray area between the black and white areas. Fuzzy logic is utilized in many areas of engineering design applications from space crafts to washing machines and even in the area of law. Am I on the same page as Profes...

John I really appreciated your snake story analogy. I find that my reactions to different situations surely falls into this category, and embarrassing to say I am 59 years old, retired and should know better. I am not a member of SD and probably wont be, but I really enjoy the dialog that takes plac...

I have been away from the area of physics for some time. But if my memory has not failed me, once one enters the atomic world, the world of particle physics, cause and effect become possibly an illusion, fuzzy. I cant believe I said that, after being an engineer for so long. Does "cause and eff...

Geoff Coyle, I guess I did miss the point, I was trying to share the idea that there is uncertainty in everything, except death and taxes. The probability distribution approach was one way of expressing uncertainty in a quantitative manner. I think it is fair to say that no matter how confident one ...

With regards to Geoff Coyles comments below: Another possible approach to utilizing X=A*B*C is to express each one has a probability distribution. For example A could be a Triangular Distribution with a Low, Expected Value, High. This distribution comes from subject matter expertise. If you know muc...

Hi Ted, I am in agreement with you. I spent many years of my early engineering days modeling engineering systems with linear and non-linear differential equations etc., and worked myself into the really hard stuff called business system dynamics. The approach of SD methodology is identical , in my o...

Happy New Year!! I am interested in reviewing dynamic models of " Order To Delivery" of an automobile. I am particularly interested in including the purchasing, design, supplier chains, dealers etc. workflow dynamics in the model. The vision I have in mind includes a global perspective of ...

Sala, I need a little more information from you. What is the purpose of your dynamic model? Are you modeling the work flow of the various organizations versus the customer requirements etc. to enhance the work flow process? Does the work flow process include Doctors, Nurses, Admin people etc.? What ...

Ms. Tullar,
Refer to the "i" Think software package reference materials by High
Performance Inc. They have a consultanting model already done that you
may use as a reference.

Sincerely,

I am in agreement with you Professor Coyle. I am an ex control system engineer, it is amazing what a process model of a single time delay and a 2nd order differential equation can do for you. If I am understanding your comments Professor Coyle, a time delay process with proportional control only wil...
