Thus, it is necessary for the retailer to take consumers' fairness concerns into account when setting his pricing policies. We assume that when the retailer's price is lower than a consumer's justice reference price, the consumer is likely to sense a positive price unfairness that will lead to increased consumer utility, and when the retailer's price is higher than a consumer's justice reference price, the consumer is likely to sense a negative price unfairness-that will have a negative effect on consumer utility. According to the information conditions of the consumers' justice reference price, the retailer should consider three situations: certain information, random information and partial information. In all situations, we show that the retailer has a unique optimal pricing strategy. Finally, through numerical examples, we find that our distribution-free policies perform almost the same as the results under the distributions that maximize the entropy. Our results reveal that it is important for the retailer to consider consumers' fairness concerns, otherwise he may suffer losses when Pc is very small.展开更多

In the proposed design, the switch power consumption and short-circuit power consumption are balanced by discharging and pre-charging the key nodes of the output circuit and adding an additional shortcircuit current path. Thus, the power consumption is constant in every read cycle. As a result, the DPA-resistant ability of the SRAM is improved. In 65 nm CMOS technology, the power balance SRAM is fully custom designed with a layout area of 5863.6 μm^2.The post-simulation results show that the normalized energy deviation(NED) and normalized standard deviation(NSD) are 0.099% and 0.04%, respectively. Compared to existing power balance circuits, the power balance ability of the proposed SRAM has improved 53%.展开更多
