Direct vs. Indirect Materials Purchasing l Direct materials (直接物料) Materials that become part of the finished product in a manufacturing process l Replenishment/Contract purchasing (补货采购/ 合同采购) l The company negotiates long-term contracts for most of the materials that it will need l l When actual demand is higher than company’s expected demand, it must buy additional material 13
Direct vs. Indirect Materials Purchasing Cont’d l Purchases are made in a loosely organized market called a spot market (现货市场) l This second type of direct materials purchasing is called spot purchasing (现货采购) l Indirect materials (间接物料) l Other materials that the company purchases, including factory supplies l l Office depot China http: //law. asiaec. com/ Staples http: //www. staples. com. cn/website/Default. html 14

Logistics Activities Cont’d l Receiving (收货), warehousing (仓储), controlling inventory (库存 控制), scheduling and controlling vehicles (车辆的调度和控制), and distributing finished goods (产成品的分销) are all logistics activities l For example, l l l the Schneider Track and Trace system delivers real-time shipment info to its customer J. B. Hunt lets its customer track their shipments themselves When transportation and freight companies engage in the business of operating all or a large portion of a customer’s materials movement activities, the company is called a third-party 16 logistics provider (第三方物流服务商)

Network Model of Economic Organization l One trend becoming clear in purchasing, logistics, and support activities is the shift away from hierarchical structures toward network structures l Some researchers studying the interaction of firms within an industry value chain are beginning to use the term “supply web” instead of “supply chain” l The emerging networks of firms are more flexible and can respond to changes in the economic environment much more quickly 21

Commonly used UN/EDIFACT Transaction Sets 29
How EDI Works l EDI l l Implementation can be complicated Example l l Consider company that needs a replacement for one of its metal-cutting machines (金属切割机床) Paper-based purchasing process l l Buyer and vendor are not using any integrated software for business processes internally Information transfer between buyer and vendor is paper based 30

Direct connection (直接连接) EDI l Direct connection EDI l Requires each business in the network to operate its own on-site EDI translator computer l EDI translator computers are connected directly to each other using l Modems and dial-up telephone lines or dedicated leased lines (专线) 33
Direct Connection EDI 34
Value-Added Networks (增值网) l Indirect connection (间接连接) EDI l To send an EDI transaction set to a trading partner l VAN customer connects to the VAN then forwards EDI formatted message to VAN logs the message and delivers it to trading partner’s mailbox l Trading partner then dials in to the VAN and retrieves its EDI-formatted messages 35
Indirect Connection EDI through a VAN 36
Advantages of using a VAN l Users need to support only the VAN’s one communications protocol l The VAN l Records message activity in an audit log (运行记录) l Can provide translation between different transaction sets used by trading partners l Can perform automatic compliance checking 37
Disadvantages of using a VAN l Cost l Most VANs require l l An enrollment fee (注册费), a monthly maintenance fee (月租费), and a transaction fee (交易费) Using VANs can become cumbersome and expensive for companies that l Want to do business with a number of trading partners, each using different VANs 38
EDI on the Internet l Initial roadblocks to conducting EDI over the Internet l l l Concerns about security Internet’s inability to provide audit logs and thirdparty verification (第三方验证) of message transmission and delivery Nonrepudiation (不可否认) l Ability to establish that a particular transaction actually occurred 39
Open Architecture of the Internet l Internet EDI or Web EDI l l l EDI on the Internet Also called open EDI Open architecture of Internet l l Allows trading partners unlimited opportunities for customizing information interchanges New tools such as XML l Helping trading partners be even more flexible in exchanging detailed information 40

Financial EDI Cont’d l Value-added banks (VABs, 增值服务银行) l l Banks that offer VAN services for nonfinancial transactions Financial VANs (FVANs, 金融增值网) l Nonbank VANs that can translate financial transaction sets into ACH formats 42
Supply Chain Management (供应链管理) l l When companies integrate their supply management and logistics activities across multiple participants in a particular product’s supply chain, the job of managing that integration is called supply chain management Supply chain management l Was originally developed to reduce costs l Is now used to add value in the form of benefits to the ultimate consumer at the end of the chain, which requires a more holistic view (全局的观点) of the entire supply chain 43
Supply Chain Management Cont’d l Businesses that engage in supply chain management l l Establish long-term relationships with small number of capable suppliers – tier one suppliers ( 一级供应商) Tier one suppliers l Develop long-term relationships with larger number of suppliers that provide components and raw materials – tier two suppliers (二级供应商) 44
Supply Chain Management Cont’d l Tier two suppliers l l Manage relationships with the next level of suppliers – tier three suppliers (三级供应商) Supply alliances (供应联盟) l Long-term relationships created among participants in the supply chain 45
Internet Technologies and the Supply Chain l Key elements of successful supply chain management l l l Clear communications (明确的沟通) and quick responses (快速的响应) Technologies, especially Internet and Web technologies, can be very effective communications enhancers Major disadvantage of using Internet technologies in supply chain management l The cost of the technologies 46
47
Increasing Supply Chain Efficiencies l Many companies are using Internet and Web technologies to manage supply chains that yield increases in efficiencies l These companies have found ways to increase process speed, reduce costs, and increase manufacturing flexibility l Examples l Boeing, the largest producer of commercial aircraft l Dell Computer, famous for use of Web to sell customconfigured computers 48
Using Materials-Tracking (物料跟踪) Technologies with EDI and EC l In many industries, the integration of bar coding and EDI has been prevalent for tracking materials movement l In the 2 nd wave of electronic commerce, companies are integrating new types of tracking, such as radio frequency identification devices (RFIDs, 无线射频标签) l The passive (被动) RFID tag l Includes information about the inventory item l Can be made cheaply and in small size l Does not need a power source 49
Creating an Ultimate Consumer Orientation (最终的消费者导向) l One goal of supply chain management is to help each company in the chain focus on meeting needs of consumer at the end of the supply chain, which are often called ultimate consumer orientation l One company pioneering the use of Internet technology to facilitate creating ultimate consumer orientation is Michelin North America l Most IT and purchasing managers believe that IT helps to improve their firm’s relationships with suppliers and supply chain management 50
Building and Maintaining Trust in the Supply Chain l Major issue for most companies to form supply chain alliances l l Developing trust Key elements for building trust l Continual communication (持续的沟通) and information sharing (信息共享) 51
Building and Maintaining Trust in the Supply Chain Cont’d l Procurement professionals build trust on years of doing business with the same vendor l Vendors send sales representatives to call on buyers regularly l Vendors participate in trade shows (贸易展) and conferences l Vendors are finding that the Web gives them opportunity to stay in contact with customers more easily and less expensively 52
