Another specific query came up in my recent survey – how to model and manage the often complex dynamics of supply chains.
This has been a gap in my work, simply because it has not come up for me !!
But it has come up for other experts. Indeed, it is one of the earliest and most developed f uses for system dynamics SD models. Check out the work of Henk Akkermans at Tilburg University (a practical professional, as well as top academic), and his book Supply Chain Dynamics: Mastering Disruptive Change in Innovation Driven Industries.
A quick search of Google Scholar will find other experts on the topic.
