Genetic algorithm optimised Hadamard product method for inconsistency judgement matrix adjustment in AHP and automatic analysis system development

•We propose a new consistency adjustment method of AHP judgement matrix.•This is named genetic algorithm optimised Hadamard product (GAOHP).•It helps avoid excessive correction and retains the original matrix information.•This is a feasible solution for the optimisation problem at an acceptable cost.•Newly developed analysis software system set is effective for AHP analysis.
