Based on discussion on the necessity of the reform of the management system of university library under the network environment,this paper probes into the reform and innovation of the management system of library form four aspects of the networking of the organizational structure,the digitalization of the literature management,the scientific management of the talents and the construction of the good environment.
This paper analyzes on the problems existing in the services of the library of high professional college,and puts forward some concrete measures for strengthening the library's traditional services and developing some innovation items of the service under the network environment.
Connecting with the modern informaiton technology and computer network technology, this paper advances the modes of modern audio-visual service, analyzes on the the contents and conditions of the modern audio-visual service , and expounds some problems in and the countermeasures for the audio-visual service.
A recognition problem in converting linear programming to network flow models
A routing in a network assigns to each ordered pair of nodes a fixed path.
When either a node or a link in a fault-tolerant network fails, the communication from one node to another using this faulty element must be sent via one or more intermediate nodes along a sequence of paths determined by this routing.
An important and practical problem is how to choose a routing in the network such that inter-mediate nodes to ensure communication are small for any fault-set.
The result shows that most inverse network optimization problems with l∞ objective function can be solved in the polynomial time.
