An Approximate Algorithm for a Class of Nonlinear Bilevel Integer Programming

The algorithm for a class of nonlinear bilevel integer programming is discussed in this paper. It is based on the theory and algorithm for nonlinear integer programming. The continuity methods for integer programming are studied in this paper. After simulated annealing algorithm is applied to the upper-level programming problem and the thought of filled function method for continuous global optimization is applied to the corresponding lower-level programming, an approximate algorithm is established. The satisfactory algorithm is elaborated in the following example.     

The Risk Evaluation of the Implement for Enterprise E—Business

In this paper, risk evaluation index system of electronic business is put forward for core manufactures. At the same time, risk evaluation method is established on the basis of fuzzy mathematics and grey theory, and its effectiveness and feasibility are tested in the practical example.

多米诺骨牌理论不适用于萨尔瓦多

这是美国《纽约时报》3月9日刊登的一篇文章,现摘译如下: 为了保证国会支持向萨尔瓦多提供六千万美元的紧急军事援助,里根政府又提出了多米诺骨牌论。照这种不祥的警告,如果萨尔瓦多倒台的话,所引起的反响将会推翻从巴拿马到墨西哥的各国政府。这种已被越南战争证明是极不可信的比喻为何再次为美国制订政策者所想到了
