Abstract

Multi-resolution modelling (MRM) has been increasingly applied in engineering practice. While in a distributed simulation environments, time advance method for MRM is less studied. When the system is running in a relatively low-resolution status, it usually adopts basic time advance modes to save simulation resources. However, these basic modes usually suffer from inaccurate response of interactions and are separate from the resolution switching process. In this paper, we propose an improved time advance method for distributed multi-resolution models. We introduce an interaction table to enable dynamic management of interactions, and decouple the interaction request process from the interaction response process, resulting in a more fine-grained interactive mode. Moreover, the interactive deviation index is introduced to quantitatively characterize the cumulative errors from delayed interactions. This index has been incorporated into resolution switching conditions to provide a more flexible and intuitive way for multi-resolution modelling. Proposed method has been verified on both theoretical cases and practical applications, and can achieve high simulation accuracy with less time consumption.

一种用于分布式多分辨率建模的改进型时间提前法，具有交互式偏差特征描述功能

多分辨率建模（MRM）在工程实践中的应用越来越广泛。而在分布式仿真环境中，MRM 的时间提前方法研究较少。当系统在相对低分辨率状态下运行时，通常会采用基本时间提前模式来节省仿真资源。然而，这些基本模式通常存在交互响应不准确的问题，并且与分辨率切换过程分离。本文针对分布式多分辨率模型提出了一种改进的时间提前方法。我们引入了交互表来实现交互的动态管理，并将交互请求过程与交互响应过程解耦，从而实现了更精细的交互模式。此外，我们还引入了交互偏差指数，以定量描述延迟交互产生的累积误差。该指数已被纳入分辨率切换条件，为多分辨率建模提供了更灵活、更直观的方法。所提出的方法已在理论案例和实际应用中得到验证，并能以较少的时间消耗实现较高的仿真精度。
