Andrew Kinder of Industry Week writes that greening your supply chain involves:
Optimizing the physical supply chain, storage and transportation of products across it
Lower energy usage in the manufacturing conversion process
Improving product design and packaging to minimize waste
"By moving away from spreadsheet based planning or system that relies on two variables (cost and speed), manufacturers can dynamically plan where and when to make, buy, store, and move goods based on changing fuel costs and transportation modes. The models allow manufactures to immediately see the impact of network changes to the supply chain and the bottom line."
Sounds like nothing one more class with Professor Hahn couldn't teach us.
