## Overview

DISSECT-CF-Fog models cloud-to-thing infrastructure and IoT workloads in a discrete-event simulator; its documented workflow is to configure a scenario, execute it, and analyze resource, energy, application, and cost outcomes. The tree also includes an executor for stored simulation jobs and a desktop predictor UI for time-series scenarios. The README documents web-app and converter capabilities, but their source trees are absent here. Relationships below are limited to explicit README claims and shown or indexed source references; many unsampled subsystem connections are omitted.
