主体生存力演化分析

Evolvement analysis on viability of agenrs

结合系统科学关于动态过程的观点,从生态学的角度引入了生存力的概念,并在此基础上定义了基于生存力的竞争因子的概念.将主体之间的相互关系理解为主体的生存力演化问题.用一个生存力演化模型证明了在竞争因子的反复作用过程中,主体战略集上的概率分布收敛于生存力最大集上的概率分布.从而证明了理性———在给定生存空间中对生存力最大战略的选择是生存力演化的目标.最后通过具体的事例,验证了此模型存在的现实合理性.

Combined with the dynamics process of system science, a conception of viability is introduced from the perspective of ecology. A definition of competition factor is given on the bazis of the conception of viability. The relationship between agents is comprehended as the evolvement on viability. A model of viability evolvement is used to prove that probability distribution of agent strategy set converges that of the maximum set of viability in the process of the repeated interaction of agents. That verifies that the nous, the choice of the maximum viability strategy in the given viable space, is the evolvement destination. Finally the realistic rationality of the model is illustrated through several real examples.
