Therefore, the concept of smart supply chain to be discussed in the future
should be considered together with uncertainty, and a robust model against
uncertainty must be considered together.

On the other hand, many
factories have individual and diverse uncertainties, such as weather, power
outages, and workers’ ability. Customization in the smart supply chain also implies uncertainty. Factory production
capacity is always irregular, and irregular supply chains, especially with
customized consumption, can increase the uncertainty of processing times. But existing optimization model
is very vulnerable to this uncertainty because it obtains a highly variable
optimal solution by parameters.

We refer
to the new supply chain with a concept of the CSFN as the smart supply chain.
The smart supply chain must be able to respond quickly to the small demands of
personalized products and have flexible connections between factories.

The CSFN
is an environment in which a supplier, factory or customer in the network are
connected through the cloud. With the CSFN, participants who are members of the
network can freely share information and each member can make better decisions.
Consumers can be more specific about their needs through the network. They want
to customize consumption in the network. Factories share the resources and
availability of each other to build an optimal supply chain. It also
establishes an inter-factory network to respond flexibly to the consumer’s
customized needs. This CSFN should be easy to connect and disassemble.
Suppliers can make cost-effective decisions by making optimal decisions based
on these inter-factory networks and customized consumer needs. Thus this
enables better planning and collaboration of the supply chain.

As we
enter the fourth industrial revolution, manufacturing is in a new phase. In
fact, some factories are trying to reduce costs by combining various advanced
technologies. In particular, Internet of Things (IoT) and Cloud technologies are the most popular in the manufacturing industry.
These two technologies are regarded as cutting-edge technologies that enable
free resource sharing between factories, and are being integrated through
various experiments. If these advanced technologies enable smooth sharing of
resources between factories, a new concept of smart factory that is different
from the existing one can be considered. We call these factories the Connected Smart
Factory Network (CSFN).
