The invention relates to a robustness optimization design method of an electromagnetic relay based on a preference set, relating to a design method of an electromagnetic relay. Analysis and screening of key design parameters for electromagnetic relay design purposes; establishment of a finite element calculation model for electromagnetic relay output characteristics; representation of electromagnetic relay output feature preference sets; propagation of electromagnetic relay output feature preference sets; propagation of output feature preference sets and output feature preference set representation For comparison, if there is a feasible subset in the initial design set, it is recorded as the design sub-interval is feasible at this time, and if it does not exist, it is corrected; the output feature preference set of the electromagnetic relay is reduced, and the optimal design sub-interval is selected; whether the array electromagnetic relay is Satisfy the design requirements and robustness requirements, complete the design if it is satisfied, and narrow it down until it is satisfied if it is not satisfied. By eliminating infeasible solutions and suboptimal solution sets, the preferences of design parameters are replaced by single-point solutions, and a robust optimal design interval set is obtained.
