✦ Synopsis
Development, implementation and tentative validation of a prototype of the Haztimator system, a knowledgebased (expert) system (KBS) intended to provide design and time/cost estimates for hazardous waste remediation projects, is presented. The p r o t o w evaluates one potential remedial alternative, soil vapor extraction followed by vapor-phase granular activated carbon for air emissions control. Haztimator represents the first known expert system in the environmental field with a prima y knowledge domain of system design. As shown by this work} the environmental field is a prime example of a problem domain where KBS development can be used as a tool for obtaining and exploiting "compiled" knowledgeknowledge which can be used to explain heuristics in terms offirstprinciples.
* Automated design process allows timely "what-if'' scenarios to be performed to aid in the selection of the most *KBS historically haw been termed Expert Systems (ES); this practice remuins prevalent today. H o w , KBS is a more accurate descrip tion ofthe systems referenced, and thus is used throughout this docum a t .
