In this paper, the connectivity axiom and the continuity axiom in Von Neumann-Morgenstern Rational behavior axioms are weakened. Then, a set of axiom for lattice ordered decision-making behavior, which can describe the decision-making behavior more rationally, is constructed. At last, the relative unique existence theorem for utility function is obtained.

The results show that small world network model could explain the big change of intensiveness and connectedness in forming process. And individual selection value function could explain the stable intensiveness, connectedness in growing and mature process. Combined the both, the characteristics of the whole process could be reflected.
