TUBIS is a comprehensive distribution network integrity and economic management system designed to assist gas utilities with decisions in maintenance, replacement planning, and resource allocation. The approach of TUBIS is unique in that its models are based on the advanced mathematical science of operations research.

The principal objectives of the system are to:

• Increase public safety
• Reduce risks to property
• Minimize overall short and long term costs
• Preserve and manage the integrity of the pipeline system

TUBIS uses economic criteria to assess risk and identify the optimum strategy available. TUBIS requires a minimal amount of data, is user friendly, and can integrate with Geographical Integration Systems (GIS) or work directly with a company's data using flexible modules.
