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.

Modeling and Simulation Tools and Frameworks

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.

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. This tool uses MS Access (see DEVS-Suite simulator). The DEVS-Suite simulator version 2.1.0 is integrated into CoSMoS.


Version 6.1.0, released April 2021.

Componentized WEAP and LEAP RESTful Simulators

The Componentized-WEAP (C-WEAP) and Componentized-LEAP (C-WEAP) are RESTful frameworks written in NodeJS for the Water Evaluation and Planning (WEAP) and the Low Emissions Analysis Platform (LEAP) Systems.

The nexus between the water (C-WEAP) and energy (C-LEAP) models can be modeled and simulated with the WEAP-KIB-LEAP framework. More information is available here.

C-WEAP Simulator

Version: 1.0, released May 28, 2020

C-LEAP Simulator

Version: 1.0, released February 2, 2021

Additional tools are available. See the “more software” menu for additional details.
