Title: Standardization guide for construction and use of MORT-type analytic trees

Abstract

Since the introduction of MORT (Management Oversight and Risk Tree) technology as a tool for evaluating the success or failure of safety management systems, there has been a proliferation of analytic trees throughout US Department of Energy (DOE) and its contractor organizations. Standard fault tree'' symbols have generally been used in logic diagram or tree construction, but new or revised symbols have also been adopted by various analysts. Additionally, a variety of numbering systems have been used for event identification. The consequent lack of standardization has caused some difficulties in interpreting the trees and following their logic. This guide seeks to correct this problem by providing a standardized system for construction and use of analytic trees. Future publications of the DOE System Safety Development Center (SSDC) will adhere to this guide. It is recommended that other DOE organizations and contractors also adopt this system to achieve intra-DOE uniformity in analytic tree construction.
