This paper is concerned with the finite horizon linear quadratic (LQ) Stackelberg game for stochastic systems with Poisson jumps under the open-loop information structure. First, the follower solves a LQ stochastic optimal control problem with Poisson jumps. With the aid of an introduced generalized differential Riccati equation with Poisson jumps (GDREP), the sufficient conditions for the optimization of the follower are put forward. Then, the leader faces an optimal control problem for a forward-backward stochastic differential equation with Poisson jumps (FBSDEP). By introducing new state and costate variables, a sufficient condition for the existence and uniqueness of the open-loop Stackelberg strategies is presented in terms of the solvability of two differential Riccati equations and a convexity condition. In addition, the state feedback representation of the open-loop Stackelberg strategies is obtained via the related differential Riccati equation. Finally, two examples shed light on the effectiveness of the obtained results. 相似文献

In this paper it is shown that a class of pursuit-evasion games can be treated more simply by the geometrical approach with the topological properties of the reachable region and by the method of functional analysis. Conditions for capture and optimal strategies are derived. A numerical example is given to show both the optimal open-loop strategies of players and the optimal trajectories of the game. 相似文献

以两条包含一个制造商和一个零售商的供应链为研究对象,讨论了两供应链采用不同决策结构时链间Stackelberg博弈问题,并对链间博弈四种决策结构(分散—分散、分散—集中、集中—分散、集中—集中)进行比较分析。研究结果表明,1)对于领导者供应链来说,集中决策是其占优策略;2)对于追随者供应链来说,采用集中决策还是分散决策,则取决于产品可替代性的高低和领导者供应链的选择;3)当产品替代度较低时,集中—集中结构是链间单次和多次重复博弈的均衡解;当产品替代度较高时,集中—分散结构是链间单次博弈均衡解,而分散—分散结构则是多次重复博弈均衡策略。 相似文献

Whilst some philosophical progress has been made on the ethical evaluation of playing video games, the exact subject matter of this enquiry remains surprisingly opaque. ‘Virtual murder’, simulation, representation and more are found in a literature yet to settle into a tested and cohesive terminology. Querying the language of the virtual in particular, I suggest that it is at once inexplicit and laden with presuppositions potentially liable to hinder anyone aiming to construct general philosophical claims about an ethics of gameplay, for whom assumptions about the existence of ‘virtual’ counterparts to morally salient phenomena may prove untrustworthy. Ambiguously straddling the pictorial and the performative aspects of video gaming, the virtual leaves obscure the ways in which we become involved in gameplay, and particularly the natures of our intentions and attitudes whilst grappling with a game; furthermore, it remains unclear how we are to generalise across encounters with the virtual. I conclude by briefly noting one potential avenue of further enquiry into our modes of participation in games: into the differences which a moral examination of playfulness might make to ethical evaluation. 相似文献

基于博弈论的视角对银行监督上市公司盈余管理进行了分析,得出在现有体制下,上市公司的盈余管理行为是不可避免的,它的存在正是博弈均衡的必然结果,并且给出了相应因素(监督成本、监督效率和抵押品价值等)对均衡结果的影响;同时,指出银行只有加大惩罚力度、健全自身的公司治理机制以及完善关系银行业务等措施提高银行的监督效率,才能有效降低上市公司盈余管理程度。 相似文献

Modern control systems are featured by their hierarchical structure composed of cyber, physical and human layers. The intricate dependencies among multiple layers and units of modern control systems require an integrated framework to address cross-layer design issues related to security and resilience challenges. To this end, game theory provides a bottom-up modeling paradigm to capture the strategic interactions among multiple components of the complex system and enables a holistic view to understand and design cyber-physical-human control systems. In this review, we first provide a multi-layer perspective toward increasingly complex and integrated control systems and then introduce several variants of dynamic games for modeling different layers of control systems. We present game-theoretic methods for understanding the fundamental tradeoffs of robustness, security and resilience and developing a cross-layer approach to enhance the system performance in various adversarial environments. This review also includes three quintessential research problems that represent three research directions where dynamic game approaches can bridge between multiple research areas and make significant contributions to the design of modern control systems. The paper is concluded with a discussion on emerging areas of research that crosscut dynamic games and control systems. 相似文献

在考虑随机因素干扰的情形下,通过建立一个随机微分博弈模型研究了产学研协同创新主体间的知识共享问题。运用动态规划方法分别求得了Stackelberg主从博弈和协同合作博弈两种下均衡的知识共享策略和创新补贴比例,并对两种博弈模式下的均衡结果进行了比较。比较结果显示:(1)在Stackelberg主从博弈和协同合作博弈两种模式下,知识共享的成本及其创新能力、知识共享的边际收益及其折旧率对创新主体共享的知识量产生重要影响,当知识共享的成本及其折旧率提高时,共享的知识量将减少;当知识创新能力及其共享的边际收益提升时,共享的知识量将提高。(2)在协同合作博弈下,创新主体共享的知识量、知识创新系统的总收益、知识创新量的期望值和方差均高于Stackelberg主从博弈下的值。 相似文献

Today globally, more people die from chronic diseases than from war and terrorism. This is not due to aging alone but also because we lead unhealthy lifestyles with little or no exercise and typically consume food with poor nutritional content. This paper proffers the design science research method to create an artefact that can help people study the diffusion of serious games. The ultimate goal of the study is to create a serious game that can help people to improve their balance in physical exercise, nutrition and well-being. To do this, first we conducted 97 interviews to study if wearables can be used for gathering health data. Analysis indicates that designers, manufacturers, and developers of wearables and associated software and apps should make their devices reliable, relevant, and user friendly. To increase the diffusion, adoption, and habitual usage of wearables key issues such as privacy and security need to be addressed as well. Then, we created a paper prototype and conducted a further 32 interviews to validate the first prototype of the game, especially with respect to the diffusion possibilities of the game. Results are positive from a formal technology acceptance point of view showing relevance and usefulness. But informally in the open questions some limitations also became visible. In particular, ease of use is extremely important for acceptance and calling it a game can in fact be an obstruction. Moreover, the artefact should not be patronizing and age differences can also pose problems, hence the title not to make the serious game too serious. Future research plans to address these problems in the next iteration while the future implementation plan seeks for big platforms or companies to diffuse the serious game. A key theoretical contribution of this research is the identification of habit as a potential dependent variable for the intention to use wearables and the development of a diffusion model for serious games. The hedonic perspective is added to the model as well as trust and perceived risks. This model ends the cycle of critical design with an improvement of theory as result contributing to the societal goal of decreasing Obesities and Diabetes. 相似文献

By resorting to the vector space structure of finite games, skew-symmetric games (SSGs) are proposed and investigated as a natural subspace of finite games. First of all, for two player games, it is shown that the skew-symmetric games form an orthogonal complement of the symmetric games. Then for a general SSG its linear representation is given, which can be used to verify whether a finite game is skew-symmetric. Furthermore, some properties of SSGs are also obtained in the light of its vector subspace structure. Finally, a symmetry-based decomposition of finite games is proposed, which consists of three mutually orthogonal subspaces: symmetric subspace, skew-symmetric subspace and asymmetric subspace. An illustrative example is presented to demonstrate this decomposition. 相似文献
