Using Skewness and Kurtosis to adjust critical number of firm s credit grade migration,using Semivariance Absolute Deviation method to measure loan portfolio risks,a portfolio optimization model of banking asset based on the adjusted credit grade and the semivariance absolute deviation is set up.

A novel semi-absolute deviation optimal purchasing portfolio model for multiple markets is proposed by quantizing the risk and expected revenue rate of load serving entity.

First of all,we construct a semidiscrete finite difference scheme to Burgers equation with initial condition and Dirichret boundary conditions.
