What We Do

TFD is the world leader in the development of analytical methods and software tools for logistics decision support. If you are a planner, provider, buyer, designer, owner, operator or maintainer of a hardware system, then TFD is here to help.

For over 40 years, we have been delivering solutions that enable our Customers worldwide to make logistics decisions affecting the design, cost and performance of their systems. With proven experience of military and commercial hardware systems in the air, land, maritime and space environments, we have developed a range of software-based tools and services to help you plan, control and optimize.

Acknowledged as the world’s best practice implementations of fundamental analytical methods, the TFD Supportability Workbench is at the core of all that we do. The Workbench is a suite of software application tools that were designed specifically for use in total ownership cost analysis, spares and resource optimization, level of repair analysis, logistic support analysis, reliability modelling and options evaluation; in both static and dynamic environments. Based on an architecture that uses a central ‘common source’ structured database, the Workbench enables analysts to create and develop multiple models using the different tools, but employing an ‘enter data once, re-use many times’ approach.

In addition to TFD’s world-class software, we offer a range of services, including:

  • consultation
  • supportability audit
  • logistic analytical services
  • logistic and life-cycle cost analyst training
  • TFD software application training; and database management
