Chapter 10 – Supply Chain Management SUPPLY CHAINS – refers to the flow of materials, information, money and services through factories and warehouses, to the end customers. The Structure and Components of Supply Chains – a typical supply chain links a company with its suppliers and distributors and customers. It can involve three segments: 1. Upstream – where sourcing from external suppliers occurs. For goods and services a company needs to produce their product or service. It also includes the processes for managing inventory, receiving and verifying shipments, transferring goods etc. 2. Internal – where packaging or manufacturing takes place. Quality levels are monitored and also production output and worker productivity. 3. Downstream – distribution takes place by external distributors. Warehouses networks are developed and carriers are selected to deliver their products to customers. The flow of information can also be bidirectional. Returning goods is called reverse logistics. • Tiers of Suppliers – there could be many different tiers of suppliers. A supplier may have one or more sub suppliers and the sub supplier may have its own sub suppliers. • The Flows in the Supply Chain – materials, information, and financial flows usually occur in the supply chains.

The production is usually mass production and the products are “pushed” to the customers. If the forecasts are wrong the company can suffer serious losses. To avoid this companies use web-enabled information flows of pull-model. It is also referred to as make-to-order therefore companies only make what customers want. Not all companies however can employ the pull model, for e.g. automobile companies. Problems Along the Supply Chain – problems with supply chains occur when products are not delivered to customers. Sometimes they can provide poor quality products. There are also other friction factors such as high inventory costs and loss of revenues. The pro
