The optimization method of roving process parameters combining orthogonal test and TOPSIS was discussed. Based on orthogonal test data,TOPSIS method was used to deal with the test data to obtain the best process program. Proportional scaling method was adopted to modify the calculation weight traditional scaling method. Single objective optimization and comprehensive multi objectives optimization were used to decide the optimized technology program. Verification test was done to prove reliable and efficient optimization results. It is considered that the adoption of TOPSIS method ean overcome the issues including rougher treatment and lower resolution ratio of orthogonal test data. It ean improve the accuracy of optimization results effectively.
