| Abstract |
This article analyses the output rate in twomachine
flexible robotic manufacturing cells. The flexible
CNC machines in this manufacturing cell can process
different operations. The manufactured parts in the cell
are identical and it is assumed that different operations
are required to manufacture each part. Moreover,
loading/unloading time of a part by the robot ( ) , robot
movement time between the machines and input and
output areas ( ) , and processing time of the jth part on the
machines (tj) are considered to be fixed. The main
objective of this article is to minimize cycle time in order
to increase the output rate of the manufacturing cell. To
achieve this goal, it is important to optimally assign
operations required for manufacturing a part to each
machine and to determine the optimal robot moves
sequence. Accordingly, existing feasible movement
policies in the cell and their cycle times have been
reviewed, and then these policies have been considered in
a new machine layout and their cycle times have been
calculated based on the new robot moves sequence.
Afterwards, a mathematical model has been presented to
select optimal cycle time in the manufacturing cell and
this model has been solved by a branch and bound exact
algorithm; since the mathematical model is non‐linear
and the optimal solution cannot be obtained, two
metaheuristic algorithms—genetic and simulated
annealing algorithms—have also been proposed to solve
the model and their results have been compared. |
