Aiming at the shortcomings in evaluating performance management of maintenance costs of military equipment, takes fuzzy comprehensive evaluation to evaluate performance management of maintenance costs of military equipment. based on the fuzzy comprehensive evaluation principle, analyzes evaluating indicators of maintenance costs of military equipment, determines grades of the indicators using the expert point system and the weight coefficients of the indicators using the method of AHP, creates the fuzzy comprehensive evaluation model of the maintenance costs of military equipment and take some army an example is analyzed. The result indicates the model can take exactly the condition of performance management of maintenance costs of military equipment, find out the difference of the level of performance management and increase management efficiency.
