TDI and the TNDM
The Dupuy Institute does occasionally make use of a combat model developed by Trevor Dupuy called the Tactical Numerical Deterministic Model (TNDM). That model is a development of his older model the Quantified Judgment Model (QJM).Â
Â
There is an impression, because the QJM is widely known, that the TNDM is heavily involved in our work. In fact, over 90% of our work has not involved the TNDM. Here a list of major projects/publications that we done since 1993.
Â
Based upon TNDM:
Artillery Suppression Study – study never completed (1993-1995)
Air Model Historical Data feasibility study (1995)
Support contract for South African TNDM (1996?)
International TNDM Newsletter (1996-1998, 2009-2010)
TNDM sale to Finland (2002?)
FCS Study – 2 studies (2006)
TNDM sale to Singapore (2009)
Small-Unit Engagement Database (2011)
Â
Addressed the TNDM:
Bosnia Casualty Estimate (1995) – used the TNDM to evaluate one possible scenario
Casualty Estimation Methodologies Study (2005) – was two of the six methodologies tested
Data for Wargames training course (2016)
War by Numbers (2017) – addressed in two chapters out of 20
Â
Did not use the TNDM:Â
Kursk Data Base (1993-1996)
Landmine Study for JCS (1996)
Combat Mortality Study (1998)
Record Keeping Survey (1998-2000)
Capture Rate Studies – 3 studies (1998-2001)
Other Landmine Studies – 6 studies (2000-2001)
Lighter Weight Armor Study (2001)
Urban Warfare – 3 studies (2002-2004)
Base Realignment studies for PA – 3 studies (2003-2005)
Chinese Doctrine Study (2003)
Situational Awareness Study (2004)
Iraq Casualty Estimate (2004-2005)
The use of chemical warfare in WWI – feasibility study (2005?)
Battle of Britain Data Base (2005)
1969 Sino-Soviet Conflict (2006)
MISS – Modern Insurgency Spread Sheets (2006-2009)
Insurgency Studies – 11 studies/reports (2007-2009)
America’s Modern Wars (2015)
Kursk: The Battle of Prokhorovka (2015)
The Battle of Prokhorovka (2019)
Aces at Kursk (2021)
More War by Numbers (2022?)

Â
Our bread and butter was all the studies that “did not use the TNDM.” Basically the capture rate studies, the urban warfare studies and the insurgencies studies kept us steadily funded for year after year. We would have not been able to maintain TDI on the TNDM. We had one contract in excess of $100K in 1994-95 (the Artillery Suppression study) and our next TNDM related contract that was over $100K was in 2005.
