摘    要：It is well known that classical optimal designs depend on an assumed model which may not be a true model. To overcome this, Bayesian designs were introduced. For response surface experiments, the prediction of the response is an important task. Bayesian I-optimal designs minimize the average variance of prediction, thereby increasing the prediction efficiency. We introduce three new Bayesian optimality criteria for constructing optimal designs that have high prediction efficiency and less dependence on an assumed model. Optimal designs are obtained using the Bayesian I-criterion and the newly introduced criteria. The performance of the criteria is compared with that of existing optimality criteria using graphical methods and some efficiency measures.
