论文摘要
几乎没有探索基于代理的模型中参与者选项的明确模拟及其演变。这项研究建议将提供的能力用作代理环境和代理行动之间的中间实体。我们在法国东南部的典型重力喂养网络上说明了这种方法，以探讨传统水的放弃如何改变灌溉者的灌溉选择。我们在两个机构安排下模拟了一个典型的干旱年度灌溉季节（即通过每日插槽及其放弃的传统协调）。仿真结果与现场调查是一致的，并且揭示了灌溉器之间的内部冲突数量增加，这是放弃传统水的遗弃。它们还强调了集体机构中灌溉者利益的异质性的后果。对模型的敏感性分析允许识别最佳协调方式，并在过去和当前的机构安排之间存在潜在的妥协。在ABM中使用负担能力的关键好处在于研究其人口动态，以表征参与者与其环境之间的相互作用情况，并更好地理解模型动态。
There has been little exploration of the explicit simulation of the set of options of actors in agent-based models and its evolution over time. This study proposes to use affordances as intermediate entities between agents' environment and agent actions. We illustrated the approach on a typical gravity-fed network in the South-East of France to explore how the abandonment of traditional sharing of water changes the irrigators' options to irrigate. We simulated a typical dry year irrigation season under two institutional arrangements (i.e. traditional coordination through daily slots and its abandonment). Simulation results are consistent with field surveys, and reveal an increase in the number of internal conflicts among irrigators as the counterpart of the abandonment of traditional sharing of water. They also highlight the consequences of the heterogeneity of the irrigators' interests within the collective institution. The sensitivity analysis of the model allowed identification of optimal modalities of coordination, and a potential compromise between past and current institutional arrangements. The key benefits of using affordances in ABM lie in the study of their population dynamics for characterizing the interaction situations between actors and their environment and for better understanding the model dynamics.
