Simulation and Modelling

Notes The company will initially launch the WIWO mobiles in South India and leverage on its
sales and service network of 125 centres in the region. The national rollout is expected in
three months.
Mr Sudhir said the WIWO mobiles target the country’s discerning youth, as they aspire for
differentiated yet relevant products.

United Telecom Group Chairman Dr C. Kasarbada Rao said the group has invested over
` 200 crore in telecom manufacturing infrastructure.
“With a projected turnover of ` 270 crore, ` 460 crore and ` 690 crore in 2011, 2012 and 2013
respectively, the future plans of WIWO Mobiles include an in-house product design and
development lab at a cost of ` 5 crore, and a product testing and simulation lab at a cost of
` 5 crores by 2011. The company also plans to spend ` 125 crore on marketing over the next
three years,” he said.

14.4 Summary

 Block oriented simulation languages are based on the method of analogue computers. The
system must be expressed as a block diagram that defines the interconnection of functional
units and their quantitative parameters.
 Expression oriented continuous languages are based on writing expressions (equations)
that represent the mathematical model. So the system simulated must be expressed by a
set of equations.
