Definitions and concepts
• People use different names for these chains of
activities and organisations.
• When they emphasise the operations, they refer
to the process; when they emphasise marketing,
they call it a logistics channel; when they look at
the value added, they call it a value chain, when
they see how customer demands are satisfied,
they call it a demand chain. Here we are
emphasising the movement of materials and will
use the most general term of supply chain.
