A supply chain, from an operations perspective, has three components: sourcing or procurement, manufacturing and distribution, and inventory disposal. In each component, the Internet is significantly affecting how supply chains are being managed, leading to new challenges while ultimately promising to provide value.

Quantitative modeling provides companies decision support as well as insights for better management of supply chains. But there are still a number of challenges that require further OR/MS analysis.
