Reasons for which you might consider a supply chain management career • A typical box of cereal spends ____ days getting from factory to supermarket. • A typical new car spends ___ days traveling from the factory to the dealership. • Cisco’s $____ dollar write-off of inventories in 2001-2002.

Outline • Why is a Supply Chain Important? • What comprises a Supply Chain? • Supply Chain Optimization • Managing Uncertainty • Supply Chain Network Design
Supply Chain: The Magnitude • In 1998, American companies spent $898 billion in supply-related activities (or 10.6% of gross domestic product). - Transportation __% - Inventory __%, - Management __% • Third party logistics services grew in 1998 by 15% to nearly $40 billion • It is estimated that the grocery industry could save $______(10% of operating cost) by using effective logistics strategies. • Compaq computer estimates it lost $500 million to $1 billion in sales in 1995 because its laptops and desktops were not available when and where customers were ready to buy them. • Boeing aircraft, one of America's leading capital goods producers, was forced to announce write downs of $_______ in October 1997, due to “Raw material shortages, internal and supplier parts shortages…”.
Progression of Logistics Costs Total U.S. logistics costs between 1984 and 2005
Supply Chain: The Potential • Dell Computer has outperformed the competition in terms of shareholder value growth over the eight years period, 1988-1996, by over 3,000% using • Direct business model • Build-to-order strategy • Procter & Gamble estimates that it saved retail customers $65 million through logistics gains over the past 18 months. “According to P&G, the essence of its approach lies in manufacturers and suppliers working closely together …. jointly creating business plans to eliminate the source of wasteful practices across the entire supply chain”.
Critical Success Factors • EDLP Strategy • Channel Master • EDI-INT, IT Strategy _______’s level of supply chain management is so efficient that there is almost no need for warehouses. Inventory is moved from one location to another quickly and efficiently, thereby cutting costs.
What Is a Supply Chain? • Flow of products and services from: • Raw materials manufacturers • Intermediate products manufacturers • End product manufacturers • Wholesalers and distributors and • Retailers • Connected by transportation and storage activities • Integrated through information, planning, and integration activities
The Supply Chain Network Price & product availability
What Is the Goal of Supply Chain Management? • Supply chain management is concerned with the efficient integration of suppliers, factories, warehouses and stores so that merchandise is produced and distributed: • In the right quantities • At the right price • To the right locations • At the right time • In order to: • Minimize total system cost • Maximize total system revenue • Satisfy customer service requirements Supply chain management is to match supply and demand better!

Why supply chain management is difficult? • Supply chain strategy linked to the Development Chain • Challenging to minimize system costs and maximize system service levels globally (Global Optimization) • Inherent presence of uncertainty and risk • All of the advanced strategies, techniques, and approaches for Supply Chain Management focus on: • - Global Optimization • - Managing Uncertainty
The Development Chain The enterprise development and supply chain
Global Optimization is Hard • The supply chain is a geographically dispersed complex network • Different facilities have conflicting objectives • The supply chain is a dynamic system • The system varies over time
Global Optimization - Complex Network National Semiconductors • Production: • Produces chips in six different locations in the US, Britain and Israel • Chips are shipped to seven assembly locations in Southeast Asia • Distribution • The final product is shipped to hundreds of facilities all over the world • 20,000 different routes • 12 different airlines are involved • 95% of the products are delivered within 45 days • 5% are delivered within 90 days.
Conflicting Objectives in the Supply Chain 1. Purchasing • Stable volume requirements • Flexible delivery time • Little variation in mix • Large quantities 2. Manufacturing • Long run production • High quality • High productivity • Low production cost 3. Warehousing • Low inventory • Reduced transportation costs • Quick replenishment capability 4. Customers • Short order lead time • Enormous variety of products • Low prices
Tools and Approaches for Global Optimization • Everything for optimization, plus… • Strategic Alliances/Supplier Partnerships • Supply Contracts/Incentive Schemes
Uncertainty and Risk Factors • Demand is not the only source of uncertainty • Lead times • Capacity • Transportation times • Natural disasters • Component availability • Forecasting does not solve the problem • Forecasting is always wrong • The longer the forecast horizon the worse the forecast • Recent trends make things more uncertain • Lean manufacturing • Outsourcing • Off-shoring
Uncertainty and Risk Factors • August 2005 – Hurricane Katrina • P&G coffee supplies from sites around New Orleans • Six month impact • 2002 West Coast port strike • Losses of $1B/day • Store stock-outs, factory shutdowns • 1999 Taiwan earthquake • Supply interruptions of HP, Dell • 2001 India (Gujarat state) earthquake • Supply interruptions for apparel manufacturers
Dealing with Uncertainty • Pull Systems • Centralization • Postponement • Strategic Alliances • Collaborative Forecasting

Supply Chain Network Design: Key Issues • Pick the optimal number, location, and size of warehouses and/or plants • Determine optimal sourcing strategy • Which plant/vendor should produce which product • Determine best distribution channels • Which warehouses should service which customers • The objective is to balance service level against • Production and purchasing costs • Inventory carrying costs • Facility costs (handling and fixed costs) • Transportation costs That is, we would like to find a minimal-annual-cost configuration of the distribution network that satisfies product demands at specified customer service levels.
