The multi-cycle inventory problems have been studied under two main assumptions. Continuous review assumption where an order can made at any time depending on inventory position and periodic review assumption where an order can be initiated only at discrete time epochs. In this study, we analyze a multi period inventory problem that falls under neither of these two assumptions. In this case we consider...
In order to reduce the influence of the jitter of hard real-time task caused by scheduling to the stability and reliability of device-level operation system, a model with preemption segment threshold-RJPS is presented. According to the effect on jitter and latency brought by threshold and the analysis of the scheduling on this model, two minimum threshold assigned algorithms are designed. One of them...
Graphs are popularly used to model structural relationships between objects. In many application domains such as social networks, sensor networks and telecommunication, graphs evolve over time. In this paper, we study a new problem of discovering the subgraphs that exhibit significant changes in evolving graphs. This problem is challenging since it is hard to define changing regions that are closely...
