The article established a kind of stability evaluation attribute model of the Logistic alliance, and then, put forward a logistic alliance stability evaluation model framework by utilizing rough sets and grey theory. A heuristic attribute reduction algorithm based on discernable matrix was set up in order to optimize attributes. The status of the logistic alliance stability was assessed through an example. The result shows: Combining rough sets and grey evaluation, the model of logistic alliance provides a quantitative analysis channel of the logistics alliance stability, so as to provide decision making basis for coordinating development and safeguarding stability of the alliance.

Light extinction method based on Lambert-Beer law is widely used in variety fidds according to its attractive features such as simplicity of principles,easy implementation and non-intrusive,A scheme of determination of dust particle size distribution with three wavelengths extinction based on light extinction method was *** feasibility and ap- plied outlook of the method were *** order to discard the requirement for prior distribution information of past inversion data algorithm,an improved genetic algorithm is proposed.A number of computer numerical calculations demonstrated that the method has the higher resolution and *** it shows the genetic algorithm has the advan- tages of high robust,insensitive to noise and also non-limit to particles complex refractive *** of these have verified the method is a useful method to the determination of dust partide size distribution.
