In view of the factor weighting involved in the equipment quality evaluation and the reasonable “lack of information” in the evaluation through the questionnaire, the induced ordered weighted evidential reasoning (IOWER) method is used to evaluate the equipment service quality. The synthetic weighting method of multi strategy is analyzed, the mixed weighting strategy is introduced, and the solution is realized by MATLAB; This paper analyzes the comprehensive evaluation of equipment use quality based on evidence reasoning under incomplete information, and analyzes the use results of equipment of an artillery battalion. The analysis results show that the use of IOWER method is conducive to draw more accurate evaluation conclusions.
