SYSTEMS APPROACH TO BRIDGE STRUCTURE REHABILITATION OR REPLACEMENT DECISION-MAKING

This paper presents a systems approach to the difficult bridge structure rehabilitation or replacement decision-making. Essential elements of the data base, or structure information system, supporting this decision-making process are indicated. Adequacy for future use and economic criteria for a rational appraisal of alternates are developed and their application is indicated. Constraints, such as available and projected flow of funds and of local or legal nature are identified and their impact on decisions are analyzed. Analytical decision methods, such as pay-off matrix and decision tree, for evaluation of alternate proposals are presented and illustrated in a systematic, step-by-step procedure. Guidelines are also presented to assist the decision-maker in the selection of a method suitable for individual situations. /Author/
