Solution Overview

Problem

Current systems for managing chassis resources in intermodal hub facilities (IHFs) suffer from inefficiencies due to the static nature of chassis allocation and utilization, leading to suboptimal use of resources, increased waiting times, and operational bottlenecks.

Innovation Solution

A system for dynamic classification of chassis pools that uses a dual-stream resource optimization (DSRO) approach to optimize the utilization of chassis resources. This system includes configuring dynamic chassis pool classifications with rulesets, guidelines, performance metrics, and constraints to manage and operate chassis pools efficiently.
