Abstrakt
Management of agricultural operations is currently rapidly changing caused by
increased
attention to the concepts of sustainable development and sustainable intensification.
Enhancement of productivity and efficiency of agricultural machinery are the leadi
ng factors in
sustainable agriculture. The complete application and exploitation of engineering advances
require the revision of traditional
agricultural
machinery management process. The definition of
the farm fleet (tractors and implements), as well as m
achinery planning and management, must
consider different parameters, including not only the cost of the machines but also their
dimensions, weight, working width, needed power, etc. All of this information related to an
agricultural
machine
is eventually
influencing the impact on productivity, on the return on the
investmen
t, and also on the environment.
The present work
is aimed
at identifying the most relevant parameters which are influencing costs
and performances of sprayers, including tank volume, max
imum flow, needed power, weight and
price. The different
parameters
are analysed
in a correlation matrix,
in order to
allow
identification of dependencies a
nd to extract reference models.
The study
is based
on linear and multiple linear regression analysis
carried out on technical
specifications of about 700 models of sprayers. Relevant correlations
were highlighted
between
price and weight, between weight and tank capacity and in some cases between power and
weight
.
Following such
correlations
, models have
been proposed, which can
be implemented
in order to
support the decision making phases.
