这一章引导读者阅读本书中的材料。它首先概述了基于主体的模型/建模(ABM)的含义和基本原理，重点介绍了它们的历史、它们是如何演变的，以及它们如何处于地理系统建模和模拟的更广泛的背景下。然后概述了我们认为对ABM至关重要的三个主题，即ABM代表前者的细节与模型和数据简洁性的问题，由此产生的模型验证问题，以及关于ABM在多大程度上是应用方面的通用或特定风格的问题。我们根据使用各种规则对行为建模的方式来检查这些模型的本质，然后我们讨论了诸如计算、可视化、误差和模型设计方案等技术问题。所有这些都为后面的各个章节设定了背景。最后，我们简要地解释每一章所包含的内容，并指导读者如何最好地使用这本书。
This chapter guides the reader to the material in this book. It begins by outlining the meaning and rationale for agent-based models/modelling (ABM), focusing on their history, how they evolved and how they sit within the broader context of modelling and simulation for geographical systems. Three themes which we see essential to ABM are then outlined, namely the question of detail versus model and data parsimony of which ABM represents the former, questions of model validation that flow from this, and lastly issues about the extent to which ABM is a generic or specific style in terms of applications. We examine the essence of such models in terms of the way behaviour is modelled using various rules, and then we discuss technical issues such as computation, visualization, error, and schemes for model design. All this sets the context for the various chapters that follow. We conclude by explaining briefly what is contained in each chapter and by guiding the reader in how best to use this book.
