Understanding the dynamics of complex systems requires developing and combining different kinds of models that can be simulated separately and together. Modeling the interactions as separate models contributes to building flexible hybrid simulation frameworks. In this research, a Discrete Event System Specification–based Interaction Model (DEVS-IM) framework is developed based on the Knowledge Interchange Broker (KIB) approach. This KIB-based RESTful modeling composition framework is shown to enable systematic modeling and simulation of interactions between disparate simulatable models. It supports storing IMs developed for componentized Water Evaluation and Planning System (WEAP) and Low Emissions Analysis Platform (LEAP) tools. It generates the skeleton of DEVS-IMs stored in database for DEVS-Suite simulator. An exemplar model consisting of water, energy, and IMs demonstrates this methodology for developing nexus models of water–energy systems.

用于模拟水、能源和水-能源关系系统的知识交换代理组合建模框架

了解复杂系统的动力学需要开发和组合可以单独和一起模拟的不同类型的模型。将交互建模为单独的模型有助于构建灵活的混合仿真框架。在本研究中，基于知识交换代理（KIB）方法开发了基于离散事件系统规范的交互模型（DEVS-IM）框架。这种基于 KIB 的 RESTful 建模组合框架能够对不同可模拟模型之间的交互进行系统建模和模拟。它支持存储为组件化水评估和规划系统（WEAP）和低排放分析平台（LEAP）工具开发的IM。它为 DEVS-Suite 模拟器生成存储在数据库中的 DEVS-IM 骨架。由水、能源和 IM 组成的示例模型展示了开发水-能源系统关系模型的方法。
