The Decision-making Method on the Probability Decision-making Space Based on SPA Probability Lattice Ordered Structure

In decision-making process, as the uncertain decision-making state is influenced by the probability of events, and the method of set pair analysis is connected to the probability expression system, the SPA (Set Pair Analysis) relation function probability lattice ordered structure on the probability decision making space (omega, A, P) is defined; and based on which the decision-making method on the probability decision-making space is given. The validity is validated by an example and a new decision-making method is proposed for the lattice ordered decision making on the probability decision-making space(omega, A, P) .
