INDUSTRIAL REVOLUTION
Recent technological
evolutions, globalization, and anticipated market circumstances have crucial
clashes on manufacturing sector. As a result, continuous changes are being made
in machine and manufacturing system known as industrial revolution. If we talked
about the first revolution, it was around 17th century in which the power of
steam engine was used in place of human power. The second revolution took place
around 19th century AD as shown in figure 1, in which electrical powered
machines were used. That time, Dedicated Manufacturing system (DMS) was being
used for mass production .

Engine, transmission
parts, main components of automobiles was produced through dedicated transfer
line. In other words, in DMS product variety is less and product volume is very
high. As the time of third revolution (e.g. 1960), manufacturing sector was
struggling with the challenge of globalization. Then computer and information
technology was born. As the market globalization increased, the new
manufacturing system changed the face of industries known as Flexible
manufacturing system (FMS) where we can use a lot of Computer Numerical Machine
(CNC) and other things. All these CNC and NC machines are connected by a
computer system. The main components of FMS are work station, material
handling, & storage, human resources and computer control system.FMS later
on adapted by Ingersoll Rand in Virginia, followed by General Electricals.
Germany implemented this manufacturing system in 1969 while Japan and Russia in
1992.in the 20th century, manufacturing companies faced two problem i.e.
unexpected market changer and introduction of new products. So to stay in the
global competition, manufacturing companies started making reconfigurations in
existing manufacturing system at different levels i.e. machine level, material
handling level, layout level, process planning level and so on. By doing this,
it was possible to produce new product at a lower cost and also allow for rapid
response to market fluctuation. Yoman Koren was the first researcher who had
proposed Reconfigurable manufacturing system in 1999. RMS is defined as a
system designed for incorporating rapid modification in the capacity and
functionality of a manufacturing system by incorporating both hardware & software modules that can be rearranged or replaced .
The development stages of manufacturing system are shown in figure 2 below.
