摘　　要：利用复杂系统结构分析的方法,研究了一类确定性系统的一般随机竞争演化模型.研究发现,系统中节点的竞争力将随系统演化时间而呈指数变动,并根据节点竞争力随机增长的出现概率而存在3种不同长期趋势,且短期中系统节点的竞争力分布保持基本形态不变;同时,系统将在长期中出现竞争态势不变、均匀竞争与崩溃3种可能的状态.该模型有助于解释与预测各类无退出机制的竞争系统的演化过程与状态特征.Using complex system structural analysis method,it studies a class of deterministic system in general stochastic competitive evolutionary model.The study found that in such systems,the nodes competitiveness vary exponentially with time evolution,and they exist in three different long-term trends according to the randomly increase probability of the nodes competitiveness.In a short time,the competitiveness distribution of the system node keeps the basic form of unchanged.In the long time,the system appear the competitive situation remains unchanged,uniform competition and the collapse of the three possible states.The model helps explain and forecast the various types of competitiveness ranking system without the non-exit mechanism in the evolution and status characteristics.
