Welcome to ACIMS

Welcome to ACIMS

The Arizona Center for Integrative Modeling and Simulation is devoted to research and education that advance the evolution and use of M&S as means to develop disparate partial solutions into coherent, integrated solutions for complex, multifaceted problems.

Perspective on the modeling and simulation autocatalytic role and its past, present, and future impact on engineering, science, and people.

Simulating spatiotemporal phenomena

People, sciences, and engineering collectively shape the many kinds of intrinsically coupled natural, built, and artificial systems.

Time, space, and state concepts are integral to understanding the sustainability and resiliency of existing and evolving complex systems.

At ACIMS, research on modeling concepts, theories, and methodologies supported with the development of simulation frameworks and tools are being pursued rigorously, systematically, and flexibly created to experiment and evaluate adaptive systems’ complexity, heterogeneity, and scalability traits.

Human Breast Cancer Co-simulation: composition of agent and diffusion composable cellular automata models enabled by a Knowledge Interchange Broker (KIB) interaction model with implementation in the DEVS-Suite simulator. Simulation of this model (a 150×100 coupled CCA Diffusion) for 100 logical steps takes ~320 seconds using a Win 10 computer that has i7 2.60 GHz CPU and 64 GB RAM.

Modeling and Simulation Tools and Frameworks

Community choice award from SourceForge, issued to DEVS-Suite in 2022.

DEVS-Suite: it is a Parallel DEVS simulator with support for (i) automating the design of experiments in combination with (ii) animating models and (iii) generating superdense time data trajectories at run-time, and (iv) synchronized viewing of time-based trajectories alongside hierarchical component and I/O messaging animation.

PVM: This is a novel visual and persistent RESTful tool for creating modular and hierarchical component models. The tool separates while synchronizing the complementary visual and persistent models. Models can be independently and visually explored at multiple hierarchy levels and stored in MongoDB. The tool displays the structural metrics for any component at any level in its hierarchy.

CoSMoSim: it offers an integrated platform for system model development, simulation, & experimentation. It has a unified logical, visual, and persistent capability for specifying families of parallel DEVS, CA, & XML-Schema models. The DEVS-Suite simulator version 2.1.0 is integrated into CoSMoS.

DEVS-Suite Simulator

Version 7.0.0, released January 2023.

Predictive planning for water-energy systems: Composable Modeling & Interoperable Simulator Framework

A general composable, RESTful modeling and interoperable simulation framework supporting long-term planning of water-energy systems at realistic scales. It enables development of water, energy, and their interaction models: Componentized WEAPKnowledge Interchange Broker (KIB), and Componentized LEAP. The interactions between the water and energy models can be modeled and simulated with the WEAP-KIB-LEAP framework.

The Componentized WEAP and Componentized LEAP are RESTful frameworks written in NodeJS for the Water Evaluation and Planning (WEAP) and the Low Emissions Analysis Platform (LEAP) Systems. More information is available here.

Componentized WEAP Simulator

Version: 1.0, released May 28, 2020

Componentized LEAP Simulator

Version: 1.0, released February 2, 2021

Additional frameworks and tools are available. See the Frameworks and Tools menu for details.
