Abstract
The Department of Defense (DoD) is the key to the United States' National Security. The organizational body is responsible for being a safeguard for U.S. citizens and an integral alliance to our allies. However, the DoD has been plagued by costly overruns on defense programs that are funded to provide armaments that allow our military the ability to respond to and protect against national and international threats. These costly overruns have plagued the Department of Defense (DoD), as early as 1977 with high occurrences of cost overruns on more than 500 major defense programs resulting in tens of billions of dollars spent over the past 25 years on weapons systems that were over budget, delivered late, or canceled (Smith, 2022). The overruns limit future research and development, impede the country's defense capabilities, and disrupts the financial balance that affects taxpayers, healthcare, education, and transportation.This study examines DoD contract cost overruns by identifying and analyzing significant contributing factors and applying machine learning models to determine the likelihood of these overruns. The dataset for this research incorporated 524 records (262 overruns and 262 non- overruns) of various DoD contracts into four different supervised machine learning algorithms: logistic regression, gradient boosting, support vector machines, and random forest. The results outline which machine learning algorithm performed best using the induced dependent (overrun) and independent (factors) variables.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
