Evaluating algorithm of assembly procedure based on multi-objective harmonious group decision making

To obtain the optimum aircraft assembly sequence, an evaluating algorithm of assembly procedure based on multi-criterion harmonious group decision making was presented. Priority relationships among assembly procedures was firstly presented, and the coefficient matrix for these objectives: assembly performance, process ability, assembly cost, assembly quality, assembly time, and so on were put forward by several experts; Secondly, the maximum of harmonious values and harmonious priority values were calculated; Thirdly, if the maximum of harmonious priority value was not negative, the algorithm ended. Then the priority relationships of assembly procedures could be obtained. And the optimal assembly procedure could be selected. Finally, the algorithm was applied in evaluating assembly procedures and selecting the optimal assembly procedure for a component of a civilian aircraft's wing. Feasibility and effectiveness of the algorithm were also proved.
