Before implementation it is necessary to evaluate the proposed
system in order to ensure the functionality and maintenance under
uncertain, complex and dynamic circumstances . A logical analysis of the model in Fig. 2 must be
performed targeting the feasibility of the proposed activity actions
using the indices like efficacy, efficiency, and effectiveness. The
definitions of these indices for the proposed system stand as:
Efficacy: Data are easily transferred and used in the tractor/
implement system.
Efficiency: Obtaining all data (input) and transforming it are
carried at minimal costs.
Effectiveness: Machinery performance and the management of
decision making are improved.
