involved in manufacturing of various components located at
Karad MIDC. The company is facing with various problems
like complicated plant layout, less space for material
handling, repetitive material backtracking, more component

C) SimulatingLayout for betterproductivity:
The simulated model gives answer of the question i.e. how many Machines are really required in the process to keep
production process working properly. The simulation model should use in the system for analyses influence parameters in whole
process.

Flexsim Simulation Software is used to solve the process problem. Flexsim is new generation simulation software where
models are built directly in 3D.
