This section will cover the basics of supply chain and operations management. It will look at the difference between logistics and supply chain, the different types of supply chains, and how they are used by companies. The first thing to know is that logistics is not the same as supply chain. Logistics is a subset of supply chain that focuses on transportation management. Supply chain is broader than logistics, with it also including production, inventory management, and customer service. A company's supply chain can be categorized in a number of different ways. The two most common are centralized or decentralized. Centralized refers to one location for all processes; decentralized refers to multiple locations for various stages of production or distribution (such as manufacturing in China and distribution in America).
