Computer simulation and genetic algorithms were used to optimize peanu
t farm machinery selection. The objective of optimization was to maxim
ize net returns above machinery costs. A computer simulation model was
used to determine net returns above machinery costs. The simulation m
odel determined net returns above machinery costs for a given machiner
y set, but did not find an optimum machinery set. The optimum machiner
y set was determined using two search schemes-an exhaustive search and
an artificially intelligent search. The exhaustive search scheme invo
lved running the simulation model with all possible machinery sets, an
d then selecting the machinery set that produced the highest returns.
Alternatively, genetic algorithms were used as an intelligent search s
cheme to generate machinery sets for the simulation model. A genetic a
lgorithm found a near-optimal solution in 10% of the total time requir
ed by the exhaustive search. Modifications in the generic algorithm no
t only reduced the search time by half; but also improved the quality
of the solutions.
