-An agent-based model (ABM) is a class of computational models for simulating the actions and interactions of autonomous agents (both individual or collective entities such as organizations or groups) with a view to assessing their effects on the system as a whole. It combines elements of game theory, complex systems, emergence, computational sociology, multi-agent systems, and evolutionary programming. Monte Carlo methods are used to introduce randomness.  Particularly within ecology, ABMs are also called individual-based models (IBMs), and individuals within IBMs may be simpler than fully autonomous agents within ABMs. A review of recent literature on individual-based models, agent-based models, and multiagent systems shows that ABMs are used on non-computing related scientific domains including biology, ecology and social science. Agent-based modeling is related to, but distinct from, the concept of multi-agent systems or multi-agent simulation in that the goal of ABM is to search for explanatory insight into the collective behavior of agents obeying simple rules, typically in natural systems, rather than in designing agents or solving specific practical or engineering problems. that simulate the simultaneous operations and interactions of multiple agents in an attempt to re-create and predict the appearance of complex phenomena. The process is one of emergence, which some express as "the whole is greater than the sum of its parts". In other words, higher-level system properties emerge from the interactions of lower-level subsystems. Or, macro-scale state changes emerge from micro-scale agent behaviors. Or, simple behaviors (meaning rules followed by agents) generate complex behaviors (meaning state changes at the whole system level).
-个体为本模型模型是一类计算模型，用于模拟自治主体(个人或集体实体，如组织或团体)的行为和相互作用，以评估它们对整个系统的影响。它结合了博弈论、复杂系统、涌现、计算社会学、多智能体系统和进化规划等要素。蒙特卡罗方法用于引入随机性。特别是在生态学中，基于个体的模型也被称为基于个体的模型(IBMs) ，而在基于个体的模型中，个体可能比基于基于基于个体的模型中的完全自主的代理更简单。综述了基于个体的模型、基于主体的模型和多主体系统的最新文献，表明基于主体的模型被用于非计算相关的科学领域，包括生物学、生态学和社会科学。基于 agent 的建模与多 agent 系统或多 agent 模拟的概念有关，但又有所不同，因为 ABM 的目标是寻求对遵守简单规则的 agent 的集体行为的解释性洞察，通常是在自然系统中，而不是设计 agent 或解决具体的实际或工程问题。模拟多个主体同时进行的操作和相互作用，试图重建和预测复杂现象的出现。这个过程是一个涌现的过程，有些人将其表述为“整体大于各部分之和”。换句话说，较高层次的系统属性来自于较低层次的子系统之间的交互。或者，宏观尺度的状态变化来自微观尺度的主体行为。或者，简单的行为(意味着规则由代理遵循)生成复杂的行为(意味着整个系统级别的状态变化)。

-==History==
-The idea of agent-based modeling was developed as a relatively simple concept in the late 1940s. Since it requires computation-intensive procedures, it did not become widespread until the 1990s.
-The history of the agent-based model can be traced back to the Von Neumann machine, a theoretical machine capable of reproduction. The device von Neumann proposed would follow precisely detailed instructions to fashion a copy of itself. The concept was then built upon by von Neumann's friend Stanislaw Ulam, also a mathematician; Ulam suggested that the machine be built on paper, as a collection of cells on a grid. The idea intrigued von Neumann, who drew it up—creating the first of the devices later termed cellular automata.
-个体为本模型的历史可以追溯到冯 · 诺依曼机器，一种理论上能够复制的机器。冯 · 诺依曼提出的设备将按照精确详细的指令制作自己的复制品。冯 · 诺依曼的朋友、数学家斯坦尼斯拉夫 · 乌拉姆建立了这个概念; 乌拉姆建议这台机器应该建立在纸上，作为一个网格上的细胞集合。这个想法激起了冯 · 诺依曼的兴趣，他提出了这个想法ーー创造了第一个后来被称为细胞自动机的装置。

The location of the agents and their responsive behavior are encoded in [[algorithm]]ic form in computer programs.  In some cases, though not always, the agents may be considered as intelligent and purposeful.  In ecological ABM (often referred to as "individual-based models" in ecology), agents may, for example, be trees in forest, and would not be considered intelligent, although they may be "purposeful" in the sense of optimizing access to a resource (such as water).
-The modeling process is best described as [[inductive reasoning|inductive]]. The modeler makes those assumptions thought most relevant to the situation at hand and then watches phenomena emerge from the agents' interactions. Sometimes that result is an equilibrium. Sometimes it is an emergent pattern. Sometimes, however, it is an unintelligible mangle.
-In some ways, agent-based models complement traditional analytic methods. Where analytic methods enable humans to characterize the equilibria of a system, agent-based models allow the possibility of generating those equilibria. This generative contribution may be the most mainstream of the potential benefits of agent-based modeling. Agent-based models can explain the emergence of higher-order patterns—network structures of terrorist organizations and the Internet, power-law distributions in the sizes of traffic jams, wars, and stock-market crashes, and social segregation that persists despite populations of tolerant people. Agent-based models also can be used to identify lever points, defined as moments in time in which interventions have extreme consequences, and to distinguish among types of path dependency.
-在某些方面，基于 agent 的模型补充了传统的分析方法。当分析方法使人们能够描述系统的平衡时，基于主体的模型允许生成这些平衡的可能性。这种生成性贡献可能是基于主体的建模的潜在好处中最主流的。基于代理的模型可以解释高层次模式的出现ーー恐怖组织和互联网的网络结构、交通堵塞、战争和股市崩盘规模中的权力法则分布，以及尽管有宽容的人群仍然存在的社会隔离。基于 agent 的模型还可以用来识别杠杆点，即干预措施产生极端后果的时刻，并区分不同类型的路径依赖。

-Rather than focusing on stable states, many models consider a system's robustness—the ways that complex systems adapt to internal and external pressures so as to maintain their functionalities. The task of harnessing that complexity requires consideration of the agents themselves—their diversity, connectedness, and level of interactions.
-许多模型没有关注稳定状态，而是考虑系统的鲁棒性ーー即复杂系统适应内部和外部压力以维持其功能的方式。控制这种复杂性的任务需要考虑代理人自身ーー他们的多样性、连通性和互动水平。

-Agent-based models have replaced compartmental models, the usual type of epidemiological models. ABMs have been shown to be superior to compartmental models in regard to the accuracy of predictions. Recently, ABMs have been used to inform public health (nonpharmaceutical) interventions against the spread of SARS-CoV-2. Epidemiological ABMs have been criticized for simplifying and unrealistic assumptions. Still, they can be useful in informing decisions regarding mitigation and suppression measures in cases when ABMs are accurately calibrated.
-基于主体的模型已经取代了传统的流行病学模型——分室模型。在预测的准确性方面，反弹道导弹已被证明优于分割模型。最近，ABMs 已被用于通知公共卫生(非药物)干预措施，以防止 SARS-CoV-2的传播。流行病学上的 ABMs 因为简化和不切实际的假设而受到批评。尽管如此，在精确校准反弹道导弹的情况下，它们仍然有助于为有关缓解和压制措施的决定提供信息。

-Agent-based models have been used since the mid-1990s to solve a variety of business and technology problems. Examples of applications include marketing, organizational behaviour and cognition, team working, supply chain optimization and logistics, modeling of consumer behavior, including word of mouth, social network effects, distributed computing, workforce management, and portfolio management. They have also been used to analyze traffic congestion.
-自20世纪90年代中期以来，基于 agent 的模型被用于解决各种商业和技术问题。应用的例子包括市场营销，组织行为和认知，团队合作，供应链优化和物流，消费者行为建模，包括口碑，社会网络效应，分布式计算，劳动力管理和投资组合管理。他们也被用来分析交通堵塞。
-===In business, technology and network theory===
-Recently, agent based modelling and simulation has been applied to various domains such as studying the impact of publication venues by researchers in the computer science domain (journals versus conferences). In addition, ABMs have been used to simulate information delivery in ambient assisted environments. A November 2016 article in arXiv analyzed an agent based simulation of posts spread in the Facebook online social network. In the domain of peer-to-peer, ad-hoc and other self-organizing and complex networks, the usefulness of agent based modeling and simulation has been shown. The use of a computer science-based formal specification framework coupled with wireless sensor networks and an agent-based simulation has recently been demonstrated.
-近年来，基于 agent 的建模和仿真已经被应用到各个领域，例如计算机科学领域研究人员对出版场所的影响的研究(期刊与会议)。此外，ABMs 已经被用来模拟环境辅助环境中的信息传递。2016年11月发表在 arXiv 上的一篇文章分析了一个基于代理的模拟在 Facebook 在线社交网络上传播的帖子。在对等网络、 ad-hoc 网络和其他自组织复杂网络领域，基于 agent 的建模与模拟服务已经被证明是有用的。基于计算机科学的无线传感器网络和基于代理的仿真形式规范框架的使用最近已经得到了证实。

-Prior to, and in the wake of the financial crisis, interest has grown in ABMs as possible tools for economic analysis. ABMs do not assume the economy can achieve equilibrium and "representative agents" are replaced by agents with diverse, dynamic, and interdependent behavior including herding. ABMs take a "bottom-up" approach and can generate extremely complex and volatile simulated economies. ABMs can represent unstable systems with crashes and booms that develop out of non-linear (disproportionate) responses to proportionally small changes. A July 2010 article in The Economist looked at ABMs as alternatives to DSGE models. along with an essay by J. Doyne Farmer and Duncan Foley that argued ABMs could fulfill both the desires of Keynes to represent a complex economy and of Robert Lucas to construct models based on microfoundations. Farmer and Foley pointed to progress that has been made using ABMs to model parts of an economy, but argued for the creation of a very large model that incorporates low level models. By modeling a complex system of analysts based on three distinct behavioral profiles – imitating, anti-imitating, and indifferent – financial markets were simulated to high accuracy. Results showed a correlation between network morphology and the stock market index.
-在金融危机之前和之后，人们对作为可能的经济分析工具的 ABMs 的兴趣有所增长。反弹道导弹并不假设经济能够达到平衡，“代表性代理人”被具有多样化、动态和相互依赖行为的代理人所取代，其中包括羊群行为。反弹道导弹采取”自下而上”的方法，可以产生极其复杂和不稳定的模拟经济。反弹道导弹可以代表具有崩溃和繁荣的不稳定系统，这些系统对相对较小的变化作出非线性(不成比例)的反应。2010年7月《经济学人》的一篇文章将 abm 看作 DSGE 模型的替代品。与此同时，j · 多恩 · 法默和邓肯 · 福利的一篇文章认为，反弹道导弹可以同时满足凯恩斯代表复杂经济的愿望和罗伯特 · 卢卡斯在微观基础上构建模型的愿望。法默和福利指出，已经取得了进展，使用反弹道导弹模型的部分经济模型，但主张创建一个非常大的模式，包括低水平的模型。通过建模一个复杂系统的分析师基于三个不同的行为剖面-模仿，反模仿，无关金融市场被模拟到高准确度。结果表明，网络形态与股票市场指数之间存在相关性。
-===In economics and social sciences===
-ABMs have been deployed in architecture and urban planning to evaluate design and to simulate pedestrian flow in the urban environment and the examination of public policy applications to land-use. There is also a growing field of socio-economic analysis of infrastructure investment impact using ABM's ability to discern systemic impacts upon a socio-economic network.

-The agent-directed simulation (ADS) metaphor distinguishes between two categories, namely "Systems for Agents" and "Agents for Systems." Systems for Agents (sometimes referred to as agents systems) are systems implementing agents for the use in engineering, human and social dynamics, military applications, and others. Agents for Systems are divided in two subcategories. Agent-supported systems deal with the use of agents as a support facility to enable computer assistance in problem solving or enhancing cognitive capabilities. Agent-based systems focus on the use of agents for the generation of model behavior in a system evaluation (system studies and analyses).

-Many ABM frameworks are designed for serial von-Neumann computer architectures, limiting the speed and scalability of implemented models. Since emergent behavior in large-scale ABMs is dependent of population size, scalability restrictions may hinder model validation. Such limitations have mainly been addressed using distributed computing, with frameworks such as Repast HPC specifically dedicated to these type of implementations. While such approaches map well to cluster and supercomputer architectures, issues related to communication and synchronization, as well as deployment complexity, remain potential obstacles for their widespread adoption.
-许多 ABM 框架是为串行 von-Neumann 计算机体系结构设计的，这限制了实现模型的速度和可扩展性。由于大规模 ABMs 中的突发行为与种群大小有关，可扩展性限制可能会妨碍模型验证。这些限制主要是通过使用分布式计算来解决的，例如 Repast HPC 这样的框架专门用于这种类型的实现。虽然这些方法很好地映射到集群和超级计算机架构，但是与通信和同步相关的问题，以及部署的复杂性，仍然是广泛采用这些方法的潜在障碍。

-Since Agent-Based Modeling is more of a modeling framework than a particular piece of software or platform, it has often been used in conjunction with other modeling forms. For instance, agent-based models have also been combined with Geographic Information Systems (GIS). This provides a useful combination where the ABM serves as a process model and the GIS system can provide a model of pattern. Similarly, Social Network Analysis (SNA) tools and agent-based models are sometimes integrated, where the ABM is used to simulate the dynamics on the network while the SNA tool models and analyzes the network of interactions.
-由于基于 agent 的建模更像是一个建模框架，而不是一个特定的软件或平台，因此它经常与其他建模形式结合使用。例如，基于代理的模型也与地理信息系统(GIS)相结合。这提供了一个有用的组合，其中 ABM 作为一个过程模型，而 GIS 系统可以提供一个模式模型。同样，社会网络分析(Social Network Analysis，SNA)工具和基于代理的模型有时也集成在一起，其中 ABM 用于模拟网络上的动态，而 SNA 工具用于模拟和分析交互网络。

-Verification and validation (V&V) of simulation models is extremely important. Verification involves making sure the implemented model matches the conceptual model, whereas validation ensures that the implemented model has some relationship to the real-world. Face validation, sensitivity analysis, calibration, and statistical validation are different aspects of validation. A discrete-event simulation framework approach for the validation of agent-based systems has been proposed. A comprehensive resource on empirical validation of agent-based models can be found here.
-仿真模型的验证及确认是非常重要的。验证包括确保实现的模型与概念模型相匹配，而验证则确保实现的模型与现实世界有一定的关系。人脸验证、敏感度分析、校准和统计验证是验证的不同方面。提出了一种基于离散事件仿真的系统验证框架方法。这里可以找到关于基于主体的模型的经验验证的综合资源。

-As an example of V&V technique, consider VOMAS (virtual overlay multi-agent system), a software engineering based approach, where a virtual overlay multi-agent system is developed alongside the agent-based model. Muazi et al. also provide an example of using VOMAS for verification and validation of a forest fire simulation model.
-作为 v & v 技术的一个例子，考虑一下基于软件工程的方法，VOMAS (虚拟覆盖多智能体系统) ，在个体为本模型旁边开发了一个虚拟覆盖程序。等人。还提供了一个使用 VOMAS 模拟森林火灾模拟模型的验证及确认例子。
