Supply Chain risks are listed but suggested solutions are all from Cost World..,
In today's economic climate the major complication is VARIATION in demand, in supply, in process times,in everything.
This is why usual optimization techniques are not satisfying any more. again usual precaution to compensate the harm coming fron variation is just "computing again very fast" but unfortunately in business you can not change your mind as fast as a software can change. If you have confirmed an order to far east today it is done, you can not cancel it tomorrow!
In the book it is well stated that the most important risk factor is demand & supply uncertainity.
I believe TOC Distribution solution as described in Isn't It Obvious by Goldratt is the best solution.
