Appraisement of repair quality for engineering equipment is focused on.The appraisement attributes system is set up that contains threes aspects such as main character-index decline rate, repairing demand, reliability after equipment being repaired.The attributes system is suitable to different structure engineering equipment.A mathematical model is established by adopting engineering fuzzy set theory and multi-attribute and semi-structural fuzzy decision theory.The model about appraisement of repair quality solves the problems of aggregating semi-structural attributes and multiple decision-making information preliminarily.So the model has applicable and universal character.
