Based on the classic newsvendor model, the probability choice theory is introduced, and it is found that the perceived probability of demand for decision maker does not meet the Bayesian axioms, but is the truncated normal distribution. Therefore, the optimal inventory strategy based on perception utility is proposed, and the decision noise of different products is measured by behavioral experiments. Combining the experimental data, one simulation experiment is given to simulate the decision maker’s order behavior under different cost. Results show that the perception utility model can explain the pull to center, pull to center(PTC), phenomenon within the inventory decision-making. Furthermore, when the production costs ?? approaches (?? + ??)/2, the PTC phenomenon gradually disappears. At the same time, the unit PTC degree decreases with the increasing of ??. Thus, PTC is not an universal phenomenon, but exists in the order behavior of some products only.
