The scheduling problem of maintenance work on the equipment support station influences the support efficiency,especially for a station which repairs a large number of failed items from more than one subordinate operating *** influence of the mean time to repair （MTTR） on system availability was analyzed for maintenance stations,then the factors which determine the maintenance priority of a failed item were modeled,including the demand of the subordinate station,time and maintenance resource to repair the *** a scheduling algorithm of maintenance work on equipment support station based on dynamic maintenance priority was *** algorithm was used in an case,and the result shows that comparing to FIFO （first in,first out） method and resource fitting method,the algorithm improves the support efficiency by much while cutting down the demand for maintenance resources.

Novel congestion control approach in wireless multimedia sensor networks

The Journal of China Universities of Posts and Telecommunications 2011年第2期18卷 1-8页

Data generated in wireless multimedia sensor networks （WMSNs） may have different importance and it has been claimed that the network exert more efforts in servicing applications carrying more important information. Nevertheless, importance of packets cannot generally be accurately represented by a static priority value. This article presents a dynamic priority based congestion control （DPCC） approach that makes two major innovations in WMSNs. First, DPCC employs dynamic priority to represent packet importance. Second, it prioritizes the local traffic of motes near the base station when WMSN is highly congested. Simulation results confirm the superior performance of the proposed approach with respect to energy efficiency, loss probability and latency as well.

An IEEE 802.3 Compatible Real Time Medium Access Control with Length-based priority

引用

Journal of Donghua University(English Edition) 2006年第1期23卷 89-93页

作者：尹汝泼蔡云泽张卫东 Dept.of automation Shanghai Jiaotong University Shanghai 200030

A new medium access control method is proposed over the predominant Ethernet broadcast channel. Taking advantages of intrinsic variable length characteristic of standard Ethemet frame, message-oriented dynamic priority mechanism is established. Prioritized medium access control operates under a so-called block mode in event of collisions. High priority messages have a chance to preempt block status incurred by low priority ones. By this means, the new MAC provides a conditional detrministic real time performance beyond a statistical one. Experiments effectiveness and attractiveness of the proposed ***,this new MAC is completely compatible with IEEE802.3 .

关键词： real time Ethernet medium access control dynamic priority channel blocking preemption.

第40届中国控制会议

This paper proposes an intelligent intersection management method based on the vehicle dynamic priority. By the information interaction between the autonomous vehicles（AVs） and the infrastructure equipment, the vehicle position and posture information is obtained in real time, and the priority of the vehicles passing through the conflict points in the scene is determined according to the order of the vehicles driving through the crossroads. Subsequently, to track the planned trajectory, we use the model predictive control（MPC） algorithm minimize the intersection delay with collision-free constraints. This guarantees the vehicles to drive through the intersection safely in the scene. Simulation experiments demonstrate the reliability and efficiency of the proposed algorithm.
