The distributed air defense and antimissile kill web are characterized by complex networks of heterogeneous nodes and multiple links, and are aimed at the problems that research on the functional het erogeneity of nodes is insufficient, and assessment indexes are homogeneous in value evaluation of nodes, a hyper-network model is constructed for the reconnaissance, accusation and fire sub-network, and a method of node value evaluation is proposed based on the theory of hyper-network. The node topology, performance index and connection relationship are taken into consideration by the method comprehensively from obtaining the overall effectiveness of the kill web through the improving weighted expert scoring and entropy-grey correlation-TOPSIS algorithm to measuring the node value importance by node deletion meth od, achieving the quantitative analysis of the node value. The method is valid, providing a new idea for the value evaluation of the nodes in air defense and antimissile kill web.
