Abstract: Satisfaction degree theory is widely used in optimization, system control, management, decision-making, re- source allocation, task Scheduling, and other fields. But most of them based on background of the problem define and calculate satisfaction, which lack a universally applicable formalized satisfaction calculation model. Based on intuition fuzzy set theory, a universal multilevel intuitionistic fuzzy satisfaction degree calculation model was established. It effec- lively induces intuitionistic fuzzy satisfaction degree by using intuitionistic fuzzy filter operator. Combining qualitative and quantitative methods to calculate satisfaction degree, it makes the results more informative, scientific, reasonable and has a high automated degree. This paper analyzed the model's calculation complexity, and combining with a practical ex- ample computed the intuitionistic fuzzy satisfaction degree of shangluo tourism, and the result shows that the model is effective and practical.
