Supply Chain Management • Synchronization of activities required to achieve maximum competitive benefits • Coordination, cooperation, and communication • Rapid flow of information • Vertical integration
Supply Chain Uncertainty • Forecasting, lead times, batch ordering, price fluctuations, and inflated orders contribute to variability • Inventory is a form of insurance • Distorted information is one of the main causes of uncertainty
Information in the Supply Chain • Centralized coordination of information flows • Integration of transportation, distribution, ordering, and production • Direct access to domestic and global transportation and distribution channels • Locating and tracking the movement of every item in the supply chain
Information in the Supply Chain • Consolidation of purchasing from all suppliers • Intercompany and intracompany information access • Data interchange • Data acquisition at the point of origin and point of sale • Instantaneous updating of inventory levels
Electronic Business • Replacement of physical processes with electronic ones • Cost and price reductions • Reduction or elimination of intermediaries • Shortening transaction times for ordering and delivery • Wider presence and increased visibility
Electronic Business • Greater choices and more information for customers • Improved service • Collection and analysis of customer data and preferences • Virtual companies with lower prices • Leveling the playing field for smaller companies • Gain global access to markets & customers
Electronic Data Interchange • Computer-to-computer exchange of business documents in a standard format • Quick access, better customer service, less paperwork, better communication, increased productivity, improved tracing and expediting, improves billing and cost efficiency
1234 5678 Bar Codes • Computer readable codes attached to items flowing through the supply chain • Generates point-of-sale data which is useful for determining sales trends, ordering, production scheduling, and deliver plans
The Internet • Instant global access to organizations, individuals, and information sources • Fundamentally changes the way organizations do business • Removed geographic barriers • Adds speed and accessibility to the supply chain
The E-Automotive Supply Chain SUPPLY CHAIN PROCESS AUTOMOTIVE PAST E-AUTOMOTIVE Table 7.2
Intranets and Extranets • Intranets are internet-like networks that operate within a single organization • Extranets are intranets that can be connected to the global internet • Difference is in who has access to the system
IT Issues • Increased benefits and sophistication come with increased costs • Efficient web sites do not necessarily mean the rest of the supply chain will be as efficient • Security problems are very real • Partnership and trust are important elements that may be new to business relationships
Suppliers • Purchased materials account for about half of manufacturing costs • Materials, parts, and service must be delivered on time, of high quality, and low cost • Suppliers should be integrated into their customers’ supply chains • Partnerships should be established • On-demand delivery (JIT) is a frequent requirement
Sourcing • Relationship between customers and suppliers focuses on collaboration and cooperation • Outsourcing has become a long-term strategic decision • Organizations focus on core competencies • Single-sourcing is increasingly a part of supplier relations
E-Procurement • Business-to-business commerce conducted on the Internet • Benefits include lower transaction costs, lower prices, reduce clerical labor costs, and faster ordering and delivery times • Currently used more for indirect goods • E-Marketplaces service industry-specific companies and suppliers
Distribution • The actual movement of products and materials between locations • Handling of materials and products at receiving docks, storing products, packaging, and shipping • Often called logistics • Driving force today is speed • Particularly important for Internet dot-coms
Distribution Centers and Warehousing • DCs are some of the largest business facilities in the United States • Trend is for more frequent orders in smaller quantities • Flow-through facilities and automated material handling • Final assembly and product configuration may be done at the DC
Warehouse Management Systems • Highly automated systems • Controls item putaway, picking, packing, and shipping • Transportation management, order management, yard management, labor management, warehouse optimization
Vendor-Managed Inventory • Manufacturers generate orders, not distributors • Stocking information is accessed using EDI • A first step towards supply chain collaboration • Increased speed, reduced errors, and improved service
Collaborative Distribution and Outsourcing • Collaborative planning, forecasting, and replenishment (CPFR) • Internet-based exchange of data and information • Significant decrease in inventory levels and more efficient logistics • Companies focus on core competencies
Transportation • Important element, often overlooked • Common methods are railroads, trucking, water, air, intermodal, package carriers, and pipelines
Railroads • 150,000 miles in US • Low cost, high-volume • Improving flexibility • intermodal service • double stacking
Trucking • Most used mode in US • Flexible, small loads • Consolidation, Internet load match sites • Part of TQM supplier-customer relationship • Single sourcing reduces number of trucking firms serving a company
Air • Rapidly growing segment of transportation industry • Lightweight, small items • Quick, reliable, expensive • Major airlines and US Postal Service, UPS, FedEx, DHL
Package Carriers • FedEx, UPS, US Postal Service, DHL • Significant growth driven by e-businesses • Use several modes of transportation • Expensive • Fast and reliable • Innovative use of technologies
Intermodal • Combination of several modes of transportation • Most common are truck/rail/truck and truck/water/rail/truck • Enabled by the use of containers
Water • One of oldest means of transport • Low-cost, high-volume, slow • Bulky, heavy and/or large items • Standardized shipping containers improve service • The most common form of international shipping
Pipelines • Primarily for oil & refined oil products • Slurry lines carry coal or kaolin • High capital investment • Low operating costs • Can cross difficult terrain
Internet Transportation Exchanges • Bring together shippers and carriers • Initial contact, negotiations, auctions • Typically only one form of transportation, intermodal exchanges have been difficult to develop
The Transportation Method • Ship items at lowest cost • Sources have fixed supplies • Destinations have fixed demand

Global Supply Chain • Free trade & global opportunities • Nations form trading groups • No tariffs or duties • Freely transport goods across borders
Global Supply Chain Problems • National and regional differences • Customs, business practices, and regulations • Foreign markets are not homogeneous • Quality can be a major issue
Duties and Tariffs • Proliferation of trade agreements • Group members charge uniform tariffs • Member nations have a competitive advantage within the group

Landed Cost and Internet-Based ITL Systems • Knowing landed cost is critical in international trade • Common components are transportation charges, tariffs, duties, and taxes • ITL systems convert language and currency between trading partners
Infrastructure Obstacles to Global Trade • Some emerging markets lack suitable distribution systems, i.e. roads, rail systems • Existing roads and ports may be inadequate • Market instability, political instability • Vertical integration is a common solution
