| In the literature, there were several different versions of strategic interaction on provision of public goods games. The main difference lies in structure of payoff functions. Different structure of the payoff functions decides specific scope of application and gives a corresponding social economic interpretation.The thesis studies thoroughly and systematically different types of strategic interaction on provision of public goods games under typical net environment such as ring networks, complete networks and star networks. It also verifies equilibrium structure's feature, distribution of participants'action selection and portion of players under each type of selection on corresponding interactive mode.Under infinite plane mesh, the thesis studies conditions to achieve equilibrium state, types of structural equilibrium and minimum portion of public goods providers. The prominent contribution is identifying the structure of various kinds of structural equilibrium mesh and proves that the minimum portion of public goods providers is 20%.Based on the theoretical analysis, we also combine the design and development of cyber interaction simulation system. In view of specific network environment like ring networks, complete networks and star networks, the thesis establishes a dynamic progress design and algorithm's principle for interactive simulation system. Besides, it presents an optimality criterion by which participants take action in strategic interaction progress based on provision of public goods games.As to the network safety problems, the thesis establishes and studies link-based value allocation rules on discrete dynamic cooperative games, giving players more reasonable shares according to the topological structure of a directed graph. The quantitative assessment of all kinds of links status is very important for improving system reliability and security defense measures in dynamic decision-making support systems. |
