The invention discloses an electromagnetic relay robustness optimization design method based on a preference set, and relates to an electromagnetic relay design method. The method comprises steps of analyzing and screening key design parameters of an electromagnetic relay based on the design purpose; establishing an electromagnetic relay output characteristic finite element calculation model; representing an output characteristic preference set of the electromagnetic relay; spreading the output characteristic preference set of the electromagnetic relay; comparing the propagation of the outputfeature preference set with the representation of the output feature preference set, if a feasible subset exists in the initial design set, recording the feasible subset as a feasible design subinterval, and if the feasible subset does not exist in the initial design set, performing correction; reducing the output characteristic preference set of the electromagnetic relay, and selecting an optimaldesign sub-interval; judging whether the array electromagnetic relay meets the design requirement and the robustness requirement, if yes, completing design, and if not, reducing the output characteristic preference set again until meeting the design requirement; by eliminating infeasible solutions and the suboptimal solution set, replacing a single-point solution with preferences of design parameters to obtain a robust optimal design interval set.
