Forward logistics and reverse logistics collaborative distribution is a powerful way to reduce carbon emission because the vehicle loading efficiency can be improved. Firstly, this paper study the theoretically and proposes a forward and reverse logistics collaborative delivery model. Secondly, Design optimize the target is based on distribution distance, actual load and fuel consumption which are...
Cooperative communications is widely used to share the resources of different nodes, and achieve spatial diversity gain in multi-user network. The node which is chosen as cooperative node (cluster-head), consumes more transmit power for other nodes than itself. Because of this, traditional algorithm results in uneven power distribution. In this paper, we propose a new algorithm called weighted clustering...
Cooperative communications exploit the spatial diversity inherent in multiuser system by allowing cooperation among users having a wide range of channel qualities. How to search the cluster-head and its member relay nodes to cooperate is important. Since nodes are coming into or out of the clusters time to time, the network topology is perturbed and the reconfiguration of the network is unavoidable...
Time series clustering is an important task in time series data mining. Compared to traditional clustering problems, time series clustering poses additional difficulties. The unique structure of time series makes many traditional clustering methods unable to apply directly. This paper presents a novel feature-based approach to time series clustering, which first converts the raw time series data into...
