Model Optimasi Pemeliharaan Jalan Multi Tahun dengan Batasan Anggaran

Abstract

Pavement maintenance has longtermly been perceived as an essential factor for the road network efficiency and the driver safety. However, these activities involve the challenge issues relating to the pavement aging, the deterioration mechanism, and the available budget constraints. This paper then presents an optimization model for handling the multiyear maintenance programs in the network-level by including budget constraint. The model is developed as a mathematical programming problem, in which the Lagrange relaxation-based procedure is invoked for solving the problem. The numerical examples are also presented for providing the better insight of model application, in which the model could provide not only the multiyear maintenance programs but also the optimum budget allocation by considering the expected roughness performance of road network.
