Smart factory features
construct a smart factory a central hub of digital supply network is necessary.
Unlike the traditional production supply chain, the centralized digital supply
network can interact between various supply chain systems and the production
process can be customized. This helps in achieving a highly flexible production
and supply chain system. All the information’s are collected, processed and
transmitted by this digital core, which decides the sequence of operations to
be carried out and hence the line production system can be eliminated.
People as key
manual and semiautomatic production process the split of human resource and
utilization of the machineries determines the efficiency of the process. In a
smart factory each employee’s skill set is fed in the central digital core
system and once the employee enters the work place the system identifies the
worker (with a barcode or magnetic strips) and allots work according to his
skills. It also monitors the work done by the worker and provides him with
appropriate tools. Ergonomics of the worker is also monitored and provides
recommendations to ease of work.
central control system is then decentralized, and the information are send to
the sub artificial intelligence, which splits the work and get it done. The
main central system sends the product specification to the subsystem. The
subsystem then makes autonomous decision and starts the process by controlling
the drives, sequence and operations. The artificial intelligence continuously
monitors the changing requirements and working conditions and adopts itself
according to the atmosphere. There should be sufficient capacity to produce
high variance in products.
factory must always have fixed and open standard, which is one of the 5S
principle (standardization). These standards should be the same all over the
process and system. Once the standards are decided, there should be no
deviation from the standards to avoid malfunctioning or production of low
quality products. The standards of the Ethernet and connections should also be standardized.
Two machines with two different standards will interact between them which are
not understandable by each other and produces high scrap or rework.
