The Defense Priority Model for Department of Defense Remedial Site Ranking... 

The Defense Priority Model (DPM) is designed to provide an estimate of the relative potential risk to human health and the environment from sites containing hazardous materials. The DPM evolved from a model called the Hazard Assessment Risk Model (HARM) developed by Oak Ridge National Laboratory from 1984-1986 for the Air Force. The automation of DPM was done first in KES(r) and then in Arity Prolog(r) for use on an IBM-PC/AT class machine. The computerized model has already become more sophisticated than the paper model and as development continues, it is possible to take advantage of additional expert system features. This paper is designed as a case study of DPM development and presents the reasons for the choice of expert system environment and its evolution, the current scope of the model, and planned additions that will increase the functionality of model in the future. The methodology used to evaluate this expert system is also described. 

Development proceeded and in the Fall of 1988, a version of the code that included all of the features of HARM II was available for testing (DPM version 1.0). At this time, the name of the model was also changed to the Defense Priority Model (DPM) and it was adopted by the Office of the Deputy Assistant Secretary of Defense (Environment) for uniform use by the armed services to rank sites for remedial action in Fiscal year-1990 (4).
