The document discusses current trends in supply chain optimization. It notes that logistics costs have increased more than 50% from 2002-2007 due to globalization and long lead times. As a result, sustainability in the face of disruptions has become more important than cost minimization alone. The document also outlines the speaker's research history, including work on the traveling salesman problem, vehicle routing, supply chain optimization, and supply chain risk management. It briefly describes an ongoing project modeling supply chain languages.
Mr. Python asked the God of Python how to tidy up his messy room of toys. The God taught Mr. Python to use the list method to store his toys in boxes that fell from heaven, allowing him to access toys by their position in the list. The God then suggested using a dictionary to allow Mr. Python to immediately retrieve his toys without sorting. Using these new organizational tools, Mr. Python was finally able to efficiently manage his toys.
