From creating complex operating plans to deciphering the puzzle of retail distribution, see how we’ve transformed good decisions into better ones for companies like CSX Transportation, United Airlines and BNSF Railway.

Reoptimizing CSX Transportation’s Railroad Operating Plan

Every few years, railroads take a clean slate look at their operating plans and look for opportunities to improve. We partnered with CSX to optimize its operating plan and reduce its annual operating costs.   

Combined Assignment Models for United Airlines

The combination of two airline models into one can increase optimization opportunities. We created an integrated system for United Airlines to save the company tens of millions of dollars annually.

Optimal Repositioning of Empty Containers for Pacer Stacktrain

Empty container movements result from geographical imbalances in supply and demand. We developed a model to help Pacer Stacktrain minimize these empty container movements.

Equitable Distribution of Cars from Plants to Retailers for Toyota Motors

We partnered with Toyota Motors to develop a transportation and distribution model that meets a variety of retailer demands in an equitable manner while minimizing costs.

Locomotive Operating Plan Optimization for CSX Transportation

We developed a locomotive plan optimization application that enables CSX to regularly optimize their locomotive operating plans as changes occur in the network.

Railroad Blocking Optimizer for BNSF Railway

BNSF Railway has licensed our railroad blocking optimizer and uses it to incrementally optimize its blocking plan periodically, resulting in tens of millions of dollars in annual savings.

Railroad Blocking Optimizer for Norfolk Southern Railroad        

Norfolk Southern integrated our blocking optimizer with its own planning system to generate an optimal blocking plan. This tool is now an integral part of their operating plan development process.

Developing a Train Schedule Design for BNSF Railway         

Train schedule design is an important component of a railroad’s operating plan. BNSF Railway partnered with Optym to develop the train schedule optimizer system now known as TrainMAX®.

Creating an Optimal Linehaul Plan for Towne Air Freight

We used our HaulPLAN® software product to help a national LTL carrier create an optimal linehaul plan and considerably reduce its empty miles.

Government Agency Crew Optimization for Presence on Scheduled Airline

We developed a single-pass optimization system that scheduled 100 percent of available crew resources while improving distribution of crew on flights and honoring lifestyle requirements.


Our simulation software has helped build advanced hump yards and improve warehouse productivity, saving companies millions of dollars in capital expenditures. Learn about our work with CSX Transportation, Walmart and more.

Evaluating an Intermodal Yard Layout for CSX Using Simulation

CSX Transportation built its largest intermodal yard layout near Chicago. Using a simulation system, we evaluated the layout and designed an improved layout that increased yard capacity by over 15 percent.

Evaluating AGV Use in Walmart’s Distribution Centers

We evaluated different methods of using AGVs in Walmart distribution centers and recommended the most cost effective option for improving productivity and capacity.

An Integrated Hump Yard Simulation System for CSX Transportation

We partnered with CSX to develop an integrated hump yard simulation system to assist the company in identifying bottlenecks, capacity expansion options and yard improvement opportunities.    

Developing a Locomotive Simulation System for CSX Transportation

We developed a locomotive simulation system for CSX Transportation to help the company make strategic decisions related to fleet sizing, fleet mix, shop locations, capacities and capabilities.

Using Simulation for Making Hump Yard Capital Expense Decisions

We developed a hump yard simulation system for Belt Railway of Chicago to use when making decisions aimed at increasing capacity, reducing costs and improving efficiency.

Using Simulation to Improve Rail Network Efficiency for a Large Mining Company

When mining companies aim to increase their annual production, their railroads can often become a bottleneck in the supply chain between mines and ports. By using simulation to identify improvement opportunities in the rail network, companies can make changes to help sustain such growth in capacity.

Data Analytics

With better visibility and analysis of data, companies gain insight on their operations like they’ve never had before. Read about how our products have become vital tools for some of North America’s biggest railroads.

Using Data to Identify Missed Connection Causes at a Hump Yard

BRC’s Clearing Yard found that a large number of its cars were missing their connections from inbound to outbound trains. We identified the causes for missed connections and found solutions to address them.

Developing a Service Analyzer System for CSX Transportation

We partnered with CSX to develop its next generation service measurement and reporting systems. These systems enable users to understand current operations better and identify how to improve them.

Developing a Business Intelligence System for Canadian Pacific Railway

Data analytics and business intelligence systems can help railroad companies improve operations and reduce costs. We worked with Canadian Pacific (CP) to design, develop and deploy such an application.    


It’s a powerful pair – our products teamed with our decades of combined industry experience. See how our consulting services have saved companies time and money when implementing new systems.

Inventory Control Systems for Office Depot         

In order to maximize its revenues and improve service quality, Office Depot hired us to review and enhance its SKU allocation system as well as to design and implement a new ABC classification system.

Routing of Locomotives to Shops for Periodic Maintenance

We developed a software solution to direct locomotives to shops for periodic maintenance on a just-in-time basis while ensuring consistency with shop capacities and capabilities.

A Railroad’s Migration to Next-Generation Systems

A major European freight railroad wanted to migrate its planning and scheduling systems to next generation systems. We evaluated their strategy and made recommendations to reduce risk.
