稳健的设计在技术和运营结果存在不确定性的情况下保护系统效用。系统的系统,缺乏集中的管理控制,容易受到战略不确定性之间的协调失败部分或完全独立的系统行为体。这项工作评估了一个博弈论的均衡选择标准来衡量系统的鲁棒性战略不确定性的适用性,并研究了战略稳健设计对合作行为的影响。工作模型之间的互动代理在一个主题表示的移动的计算技术的过渡,使用进化博弈论框架。战略的鲁棒性和协作的解决方案进行了评估,在一系列的条件下,通过不同的代理人的回报。模型构建在小世界,优先连接和随机图拓扑结构上,并在批处理仿真中执行。结果表明,旨在减少来自战略不确定性的协调失败的影响,系统也增加了合作伙伴的合作概率的稳定性的合作策略;一种形式的鲁棒性的环境塑造,以前没有研究过的设计文献。工作还表明,战略选择遵循的风险优势均衡选择标准,并在协调失败的鲁棒性的变化,可以用这个标准来衡量。
Robust designs protect system utility in the presence of uncertainty in technical and operational outcomes. Systems-of-systems, which lack centralized managerial control, are vulnerable to strategic uncertainty from coordination failures between partially or completely independent system actors. This work assesses the suitability of a game-theoretic equilibrium selection criterion to measure system robustness to strategic uncertainty and investigates the effect of strategically robust designs on collaborative behavior. The work models interactions between agents in a thematic representation of a mobile computing technology transition using an evolutionary game theory framework. Strategic robustness and collaborative solutions are assessed over a range of conditions by varying agent payoffs. Models are constructed on small world, preferential attachment and random graph topologies and executed in batch simulations. Results demonstrate that systems designed to reduce the impacts of coordination failure stemming from strategic uncertainty also increase the stability of the collaborative strategy by increasing the probability of collaboration by partners; a form of robustness by environment shaping that has not been previously investigated in design literature. The work also demonstrates that strategy selection follows the risk dominance equilibrium selection criterion and that changes in robustness to coordination failure can be measured with this criterion.
