This paper studies the optimization of the (<i>S</i>, <i>T</i>) inventory policy, where <i>T</i> is the replenishment interval and <i>S</i> is the order-up-to level. First, we demonstrate that the previously established joint convexity of the long-run average cost is false. Hence, the optimization is not straightforward....

The analysis of dynamics in traffic flow is an important step to achieve advanced traffic management and control in Intelligent Transportation System (ITS). Complexity and periodicity are definitely two fundamental properties in traffic dynamics. In this study, we first measure the complexity of...

Taking Luzhai Village as a case, this paper discussed social work modes of rural women ability construction using marsh gas project, education project, handicraft project, and healthcare project as operation carrier. It focused on ability restoration and ability improvement to comprehensively...

We conjecture that the forward puzzle may reflect career risks. When professional investors observe public danger signals about a currency, they require a premium for holding it. We find evidence of this in Exchange Rate Mechanism rates. As deep discounts do signal danger, we next specify...

Without assuming the symmetry or irreducibility of the coupling configuration matrices, this paper investigates the pinning synchronization in an array of linearly coupled delayed neural networks with both constant and delayed couplings. Under some low-dimensional conditions, it is shown that...
