To reduce fuzziness of influence relationship among multiple component units with adverse effects in technology systems,realize digital calculation of the influence relationship,and ensure scientific problem ranking of the component units with adverse effects,a problem influence degree ranking algorithm based on decision-making trial and evaluation laboratory was proposed.Combining function analysis with the component units with adverse effects closely and aiming at eliminating adverse effects in technology systems,center degree,cause degree,and problem influence degree of the component units with adverse effects were defined based on component unit structure.A ranking principle of the component units with adverse effects considering the problem influence degree was established.Automatic ranking of problem solving sequence of the component units with adverse effects was realized by using graphical user interface module of MATLAB software.The results show that problem solving priority of the component units with adverse effects can be effectively determined by using the proposed algorithm.The effectiveness of the proposed algorithm is verified in an engineering case of a beam pumping unit.
