APPLICATION OF MAINTAINABILITY AND EXPECTED COST DECISION ANALYSIS TO HIGHWAY DESIGN

There are many trade-offs between construction and maintenance of highways. Conventional engineering economy methods such as the benefit-cost ratio are sometimes used to compare these trade-offs. However, conventional methods often cannot incorporate all the factors that should influence a decision. Two techniques that can extend the capabilities of the conventional engineering economy analysis are maintainability and expected cost decision analysis. These techniques are not new. They have been applied to real problems in the fields of aerospace and business administration for several years. This paper urges that these techniques be used to analyze highway design trade-offs and illustrates their use with the aid of example problems. Maintainability and expected cost decision analysis allow the engineer to use a more systematic approach to certain types of design problems. Application of this approach would lead to better decisions in many situations involving trade-offs between construction and maintenance costs.
