Transcription of Supply Chain Fundamentals & Segmentation Analysis
1 Chris Caplice Logistics SystemsSept 2006 Supply Chain Fundamentals & Segmentation Analysis Chris Caplice, MIT2 MIT Center for Transportation & Logistics Chain Management Definitions Supply Chain Management deals with the management of materials, information, and financial flows in a network consisting of suppliers, manufacturers, distributors, and customers. Prof. Hau Lee - Stanford Supply Chain Forum Call it distribution or logistics or Supply Chain management. By whatever name it is the sinuous, gritty, and cumbersome process by which companies move material, parts, and products to customers.

Chris Caplice, MIT11 MIT Center for Transportation & Logistics Chain SegmentationThere is no such thing as a one-size-fits-all Supply chainMost firms/business units operate multiple Supply chainsDifferent Supply chains require different methods for: Forecasting Demand Planning Inventory Planning Transportation Purchasing / Procurement Inventory Control Warehousing Materials Handling Order Management Transportation Customer Service Why segment?
9 Chris Caplice, MIT12 MIT Center for Transportation & Logistics & Portfolio ManagementHow many segments? (Rules of thumb) Homogenous- items within the segment are all similar Heterogeneous- items between segments should be very different Critical Mass - the segment should have enough number to make it worthwhile Pragmatic - the dimensions should be useful and communicableSegmentation in Supply Chain Management Customer, Product, Supplier More recently combinations of these Source: Prashant Yadav 2005 Chris Caplice, MIT13 MIT Center for Transportation & Logistics Chain SegmentationHow can I segment my customers/vendors?
