AN APPLICATION OF THE FUZZY SET THEORY TO THE OPTIMIZATION OF PAVEMENT REPAIR PROGRAM

Abstract

Generally, it is difficult to decide definite budget constraints at the starting stage of the pavement repair program, owing to its long analysis period. Further, in case of the number of projects are large, the sensitivity of the total life cycle cost becomes indistinct with the change of the budget constraints. In order to take these obscurity into consideration, in this study, we applied the fuzzy set theory to the optimization system of the pavement repair program.
