A new metric of wireless link quality, path efficiency, was brought forward; and traditional reliable transfer models of data link layer were analyzed based on the parameter.

From the study of Dial′s algorithm and the algorithm of K-shortest path,the concept of efficient path is redefined and further an efficient path search algorithm is developed based on traffic network.

By combining k-shortest path algorithm with bi-objective decision-making method,a practical algorithm of acquiring the efficient paths for the bi-objective shortest path problem is developed.

Combining the directional heuristic strategy with the tree searching algorithm of depth priority,an orientated tree algorithm of searching efficient paths is proposed.

Multilevel orientation algorithm for searching efficient paths in stochastic traffic assignment;

Traffic assignment is a key part of transportation planning,and the determination of efficient paths in the transportation network is the important basis of traffic assignment.

The determination of efficient paths in the transportation network is a key technology of stochastic traffic assignment.

To effectively avoid invalid workflow path and improve execution efficiency,a method of identifying invalid path of workflow was proposed.

First,we analyse the rain attenuation origin,establish the estimation formula of rain fading effect modeling and effective path calculation methods.

put forward China s university students in the entrepreneurship education model and effective path,That is,raise the level of entrepreneurship education teachers,the correct guidance and rational design of the performance of teachers,improve the education of university students entrepreneurship course sys.

School-enterprise cooperation in higher vocational education is the rational choice of development,is also the best combination points of achieving "win-win",higher vocational colleges must actively explore effective path of school-enterprise cooperation.
