Fire risk analysis: general conceptual framework for describing models

A general conceptual framework has been developed as an aid to discussions of alternative approaches to fire risk analysis. The purpose is to show how each alternative seeks to address a few common concerns. Basic concepts and key elements--notably scenario structures, appropriate probability functions, and security and outcome measures--are defined and discussed, as are types of modeling approaches. A number of diverse examples are then presented using the framework to illustrate its value in making comparisons.
