Abstract

Abstract: A Be-B decision model is proposed and the calculation of the expected value of sampling information (EVSI) for linear decision problem on two actions under the model mentioned above is discussed.By calculating the posterior distribution of the parameter，the choosing criteria about the best posterior actions is established and the best decision function is obtained.Finally，the counting formula of EVSI is given.

Key words: （Be-B）model, linear decision on two actions, expected value of sampling information, complete information
