Abstract

Multi-agent approach is very popular for modelling and simulation of complex phenomena, design and programming of decentralised computing systems. Asynchronous beings, which do not share state but communicate using messages are a convenient abstraction for representing various phenomena observed in the real world. When the number of the considered agents grows, the designers and developers of such systems must address the problem of performance. Introducing distribution is often a weapon of choice, which, however, does not guarantee obtaining proper scalability and efficiency. The intensity of communication in a large-scale agent-based system can easily exceed the abilities of a distributed hardware architecture, leading to poor performance. After analysing various distributed agent-based systems, we identified several reasons for limited performance and several architectural solutions, which can help overcoming this problem. The main aim of the presented work is identification and systematization of these architectural solutions in the form of design patterns. As a result, we propose three new design patterns for building scalable distributed agent-based systems. A systematic description of their aims, structure, variants and features is provided, together with examples of applications. PDF XML

基于代理的可扩展计算和仿真的三种新设计模式

多代理方法在复杂现象的建模和仿真、分散计算系统的设计和编程方面非常流行。异步生命不共享状态，但使用消息进行通信，这是一种方便的抽象概念，可用于表示在现实世界中观察到的各种现象。当所考虑的代理数量增加时，此类系统的设计者和开发者必须解决性能问题。引入分布式系统通常是一种选择，但这并不能保证获得适当的可扩展性和效率。大规模代理系统的通信强度很容易超过分布式硬件架构的能力，从而导致性能低下。在对各种基于代理的分布式系统进行分析后，我们发现了性能受限的几个原因，以及有助于克服这一问题的几种架构解决方案。本文的主要目的是以设计模式的形式识别这些架构解决方案并将其系统化。因此，我们为构建可扩展的分布式代理系统提出了三种新的设计模式。本文系统地描述了这些设计模式的目的、结构、变体和特点，并提供了应用实例。
