Abstract: The dynamic alliance is considered as the most promising organizational structure of the 21st century.It enhances competitive forces and makes enterprises respond to unpredictable changes of the market better.But as a new organizational form,it also has many problems to be studied.One of those is profit allocation.This paper introduces the Shapley Value algorithm and applies it to the profit allocation among cooperation partners in the dynamic alliance.Besides these,some good qualities and shortcomings are also analyzed in the paper.A modified method based on venture is presented to improve the algorithm in the end.

Abstract: In this paper,we analyzed the disadvantage of traditional TOPSIS, and presented a new decision-making method based on grey correlation degree and TOPSISThis method established a new kind of relative similarity degree by combining the Euclidean distance with grey correlation degreeThe new similarity degree reflects the distance and the different shape among a selected scheme, the ideal solution and negative ideal solutionIts implication is clearerAt the end,this method is explained by an example

Abstract: As the background value is an important factor affecting the precision of grey system model,this paper makes a research on the background value in non-equidistant GM(1,1) model.Based on index characteristic of grey model and the definition of integral,we use the discrete function with non-homogeneous exponential law to fit the accumulated sequence to propose a new method to optimize the background value in non-equidistant GM(1,1) model.The example indicates the precision of simulation and forecast by this optimized background value is obviously higher.This new formula of background value is mot only suitable in non-equidistant GM(1,1) model,but also in equidistant GM(1,1) model,and has high precision and wide applicability.

Abstract: In this paper, the concept and the expression of the partial distribution and the partial process are put forward. Bv them, the variations of commodity price can be described, analyzed, and researched. The relations of the cost price, the market price, the risk of cost price and the risk of market price of commodity are advanced in analytic expressions, which can be applied to pricing and to measuring the risks of the spots, the securities, the futures and the options in market. The Security Indexes are designed in analytic expressions. So we can use them to measure and evaluate the development security and investment security in the society, the economy, the finance, and so on.
