- 6. What is aSupply Chain? A supply chain consists of the flow of products and services from/to: --Raw materials manufacturers SEE FIGURE 1.1 --Intermediate products manufacturers --End product manufacturers --Wholesalers and distributors --Retailers and, --End customers Connected by agents, transportation and storage activities, and Integrated through sharing of information, planning, and processing activities Examples???

- 12. What is SupplyChain Management? Here are two definitions: The design and management of seamless, value-added process across organizational boundaries to meet the real needs of the end customer -- Institute for Supply Management Managing supply and demand, sourcing raw materials and parts, manufacturing and assembly, warehousing and inventory tracking, order entry and order management, distribution across all channels, and delivery to the customer -- The Supply Chain Council
- 13. What Is theGoal 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 – To the right locations – At the right time In order to – Minimize total system cost – Satisfy customer service requirements
- 14. Importance of SupplyChain Management * Firms have discovered value-enhancing and long term benefits * Who benefits most? Firms with: - Large inventories - Large number of suppliers - Complex products - Customers with large purchasing budgets * Benefits - Lower purchasing/inventory costs, higher quality/customer service
- 15. Importance of SupplyChain Mgt. – Cont. Firms practicing Supply Chain Management: 1. Start with key suppliers 2. Move on to other suppliers, customers, and shippers 3. Integrate second tier suppliers and customers (second tier refers to the customer’s customers and the supplier’s suppliers)
- 16. Importance of SupplyChain Mgt. – Cont. * Cost savings and better coordination of resources are reasons to employ Supply Chain Management -- Bullwhip Effect- the magnification of safety stocks and costs based on separate forecasts and uncoordinated planning and sharing of information along the supply chain (Ex. 1.1) * Reducing the bullwhip effect occurs through: -- Process integration- Interdependent activities can lead to improved quality, reduced cycle time, better production methods, better forecasts, less safety stock, etc.
- 17. Important Elements ofSCM Purchasing- Supplier alliances, supplier management, strategic sourcing Operations- Demand management, MRP, ERP, JIT, TQM Distribution- Transportation management, customer relationship management, network design, service response logistics Integration- Coordination/Integration activities, global integration problems, performance measurement
- 18. Important Elements ofSCM-Cont. Purchasing: •Long term relationships •Supplier management- improved performance through- -- Supplier evaluation (determining supplier capabilities and performance) -- Supplier certification (third party or internal certification to assure product quality and service compliance) •Strategic partnerships- successful and trusting, long-term relationships with top-performing suppliers
- 19. Important Elements ofSupply Chain Management-Cont. Operations: -- Demand management- match demand to available capacity -- Linking buyers & suppliers via MRP and ERP systems -- Use JIT to improve the “pull” of materials to reduce inventory levels -- Employ TQM to improve quality compliance among buyers and suppliers
- 20. Important Elements ofSupply Chain Management-Cont. Distribution: -- Transportation management- tradeoff decisions between cost & timing of delivery/customer service via trucks, rail, water & air -- Customer relationship management- strategies to ensure deliveries, resolve complaints, improve communications, & determine service requirements -- Network design- creating distribution networks based on tradeoff decisions between cost & sophistication of distribution system
- 21. Important Elements ofSupply Chain Management-Cont. Integration: -- Supply Chain Integration- when supply chain participants work for common goals. Requires intrafirm functional integration. Based on efforts to change attitudes & adversarial relationships -- Global Supply Chains- advantages that accrue from sourcing from larger global market e.g., lower cost & higher quality suppliers. May involve operating exposure, which is risk found in foreign settings -- Supply Chain Performance Measurement- Crucial for firms to know if procedures are working
- 22. Strategies for SCM Allof the advanced strategies, techniques, and approaches for Supply Chain Management focus on: Global Optimization Managing Uncertainty
- 23. Optimization * What isit? * Why is it important? * What tools and approaches help?
- 24. Tools and Strategiesfor Optimization • Decision Support Systems • Inventory Control • Network Design • Design for Logistics • Cross Docking
- 25. Global Optimization Whatis it? Why is it different/better than local optimization? What are conflicting supply chain objectives? What tools and approaches help with global optimization?
- 26. Procurement Planning Manufacturing Planning Distribution Planning Demand Planning Sequential Optimization Supply Contracts/Collaboration/InformationSystems and DSS Procurement Planning Manufacturing Planning Distribution Planning Demand Planning Global Optimization Sequential Optimization vs. Global Optimization Source: Duncan McFarlane
- 27. Why is GlobalOptimization Hard? –The supply chain is complex –Different facilities have conflicting objectives –The supply chain is a dynamic system –The power structure changes –The system varies over time
- 28. Uncertainty • What isvariation? • What is randomness? • What tools and approaches help us to deal with these issues?
- 29. Can’t Forecasting Help? Forecasting is always wrong The longer the forecast horizon the worse the forecast End item forecasts are even more wrong
- 30. Why Is UncertaintyHard to Deal With? * Matching supply and demand is difficult. * Forecasting doesn’t solve the problem. * Inventory and back-order levels typically fluctuate widely across the supply chain. * Demand is not the only source of uncertainty: – Lead times – Yields – Transportation times – Natural Disasters – Component Availability

- 34. Dealing with Uncertainty •Pull Systems • Risk Pooling • Centralization • Postponement • Strategic Alliances • Collaborative Forecasting
- 35. Supply Chain:the Magnitude •In 1998, American companies spent $898 billion in supply-related activities (or 10.6% of gross domestic product). – Transportation 58% – Inventory 38% – Management 4% • Third party logistics services grew in 1998 by 15% to nearly $40 billion
- 36. Supply Chain:the Magnitude It is estimated that the grocery industry could save $30 billion (10% of operating cost) by using effective logistics strategies. –A typical box of cereal spends more than three months getting from factory to supermarket. A typical new car spends 15 days traveling from the factory to the dealership, although actual travel time is 5 days.
- 37. Supply Chain: TheMagnitude 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 $2.6 billion in October 1997, due to “Raw material shortages, internal and supplier parts shortages…”.
- 38. Supply Chain: ThePotential 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”. (Journal of business strategy, Oct./Nov. 1997)
- 39. Supply Chain:the Potential •In 10 years, Wal-Mart transformed itself by changing its logistics system. It has the highest sales per square foot, inventory turnover and operating profit of any discount retailer. • Dell Computer has outperformed the competition in terms of shareholder value growth over the eight years period, 1988-1996, by over 3,000% (see Anderson and Lee, 1999) using –Direct business model –Build-to-order strategy.
- 40. What’s New? • Globalcompetition • Shorter product life cycle • New, low-cost distribution channels • More powerful well-informed customers • Internet and E-Business strategies
