3.2. Results and discussions
The model proposed by Guirardello was implemented with
GAMS/CPLEX 7.5, and solved by a Sun Enterprise E250 400 MHz
Optimization of the equipment positioning in manufacture of Tissue Paper 5
workstation. Initially the model was tested with its original structure, and the
algorithm was allowed to reach the best solution. Initially tests had been carried
through where if it decided the model in its original form with 15 components,
allowing that the algorithm found the best solution. To solve this problem, it
was decided to the reduce the amount of components from 15 to 10, through the
grouping of some equipment. This grouping was not arbitrary, but it was based
on the requirement of some components to be necessarily together to other
components, as for example, bombs to the side of tanks. In table 01, we present
the number of equations and variable gotten with the optimization.
