何謂環球供應鏈?

A supply chain, logistics network, or supply network is a coordinated system of organizations, people, activities, information and resources involved in moving a product or service in physical or virtual manner from supplier to customer. Supply chain activities (aka value chains or life cycle processes) transform raw materials and components into a finished product that is delivered to the end customer. Supply chains link value chains.[1]
Today, the ever increasing technical complexity of the distribution of standard consumer goods, combined with the ever increasing size and depth of the global market has meant that the link between consumer and vendor is usually only the final link in a long and complex chain or network of exchanges.
This supply chain begins with the extraction of raw material and includes several production links, for instance; component construction, assembly and merging before moving onto several layers of storage facilities of ever decreasing size and ever more remote geographical locations, and finally reaching the consumer.
Although many companies and corporations today are of importance not just on national or regional but also on global scale, none are of a size that enables them to control the entire supply chain, since no existing company controls every link from raw material extraction to consumer.
Many of the exchanges encountered in the supply chain will therefore be between different companies who will all generally seek to maximize company revenue within their sphere of interest but will have little or no basic knowledge or interest in the remaining players in the supply chain except those to which it is directly linked.
There are a variety of supply chain models, which address both the upstream and downstream sides.

The SCOR (Supply Chain Operations Reference) model, developed by the Supply Chain Council measures total supply chain performance. It is a process reference model for supply-chain management, spanning from the supplier's supplier to the customer's customer. It includes delivery and order fulfillment performance, production flexibility, warranty and returns processing costs, inventory and asset turns, and other factors in evaluating the overall effective performance of a supply chain.
The Global Supply Chain Forum (GSCF) introduced another Supply Chain Model. This framework is built on eight key business processes that are both cross-functional and cross-firm in nature. Each process is managed by a cross-functional team, including representatives from logistics, production, purchasing, finance, marketing and research and development. While each process will interface with key customers and suppliers, the customer relationship management and supplier relationship management processes form the critical linkages in the supply chain.

工業生產要好多原料供應
而呢d原料來自唔同地方/國家
eg: 煉鋼...分別要鐵礦..碳等等 少緊樣都做唔到鋼
如果其中一樣供應出現問題..咁樣市場上鋼ge供應都會受影響
佢地互相影響連繫就好伕鏈咁
