Based on analyzing the quadratic programming of SVM and using the method of feasible directions to solve the quadratic programming,this paper solves the quadratic programming by the method of feasible directions and raises a improved SVM algorithm for unlinear.

Based on the features of emergency logistics depot design optimization,the paper puts forward two-step optimization process,first,using set cover model to determine the minimum emergency logistics depot number,then using feasible location method to determine the suitable place that satisfies the demand to be the location of emergency logistics depot.

On this basis,Establish an information fusion algorithm of similar equipment to target equipment,Then give a assessment method for the reliability for the similar equipment which has similar product information.

This article,by studying relations between the normal side-coloring and the total coloring of graph using some relative results about the normal side-coloring,presents several new results,and offers a feasible method in researching the total coloring of graph.

And, we also introduce the methods dealing with the Maratos effect, the modifications of the variable metric matrix, the consistency as well as the feasible methods in the constrained variable metric methods, etc.
