Abstract
China is now the world's largest producer and consumer of nickel. As an important strategic metal, nickel is widely used in various industries of national economy. Whether the supply of nickel ore resources is sufficient or not directly restricts the development of downstream industries. It is becoming more and more important to evaluate the safety of nickel resources in our country, and to formulate the corresponding safety strategy. This paper uses fuzzy analytic hierarchy process to evaluate the safety of nickel resources in China, and overcomes the subjectivity and singleness of traditional evaluation methods. On the basis of the analytic hierarchy process to determine the weight, the fuzzy comprehensive evaluation is introduced. At present, the safety situation of nickel resources in our country is in a more dangerous level, and we need to take positive measures to improve it.
