QUERY Modeling downstream effects (SD6662)

Hi Dave,

When I model problems of this type using SD, I use a graphical time-based
function to represent the inputs.

Input variability is an essential driver, and for this you could apply a
random function to the input (quantizing and sampling from a Poisson
distribution)

Discrete simulation is another approach perhaps even more suitable for you
here, since the essential issue is queues and blocking.

I don't think theory of constraints has much to recommend it for this class
of problem; it's not at the correct level for what you want to achieve.

I am involved with the NHS programme in the UK; if this is your domain I
might be able to offer practical help.

Hope this is useful,

..george...
