The Use of the Permutation Algorithm for Suboptimising the Position of Used Nozzles on the Field Sprayer Boom

The worn-out nozzles of field sprayers cause agricultural treatment to be uneven and therefore ineffective. Spray are consumable elements the sprayer that subject inspection in event their excessive wear should replaced with new ones ensure proper execution treatment. aim study is propose, using operational research methods, an expert methodology allowing further operation often expensive nozzles, including standard, universal, anti-drift, or ejector nozzles. previous attempts, performed use random computer optimisation method, did not guarantee a global solution entire population all possible permutations without repetitions 24 (for boom width 12 m) even estimating approximation this solution. process measuring simulation virtual boom, permutation algorithm proposed here allow you specify suboptimal NP-hard problem separately for each sprayer, i.e., indicate very short time such out 24! ≈ 6.20448 × 10+23 variable degrees wear, which close optimal used on terms coefficient variation. allows reducing operating costs by relatively cheap automated service instead costly purchase set sprayers. Many areas application have been indicated.
