Abstract:

A major objective of a Pavement Management System (PMS) is to assist highway engineers and managers in making consistent and cost effective decisions related to maintenance and rehabilitation of pavement. But in many circumstances in pavement management decision making, engineers find themselves in a state of uncertainty. This stems from the incomplete, inexact information from different sources. In this paper, the application of belief-functions in a PMS analysis is discussed and the key points in the analysis are highlighted. It was considered that the variables have multiple evidences. The approach can be used to decide when sufficient evidence has been obtained to assume a decision.
