Abstract
Optimization is the core of transportation asset management, but current optimization approaches are still in the stage of single infrastructure management, which seriously hinders the development and application of transportation asset management. This paper establishes a comprehensive multi-infrastructure optimization model for transportation assets consisting of roads and bridges, which is aimed at achieving the goal of transportation asset comfort, integrity, and security, taking budget funds as constraint conditions, and applying the optimization technique of goal programming and integer programming. An interactive fuzzy linear-weighted optimum-order algorithm is presented to solve the comprehensive optimization model. Finally, the comprehensive multi-infrastructure optimization model and algorithm are verified to be effective by practical data in a case study. The results indicate that the model and algorithm can provide a satisfactory and reasonable maintenance and rehabilitation schedule for transportation asset management agencies.
Highlights
Traditional transportation infrastructure management emphasizes a single infrastructure
PONTIS was developed for bridge management by the American Association of State Highway and Transportation Officials (AASHTO) [3]; the goal of this kind of system is to provide the most cost-effective rehabilitations and replacements for bridges with limited funds available [4]
An asset management primer was compiled by the Federal Highway Administration (FHWA), which systematically addressed the basic content of transportation asset management, such as the concept, principles, and composition [7]
Summary
Traditional transportation infrastructure management emphasizes a single infrastructure. PONTIS was developed for bridge management by the American Association of State Highway and Transportation Officials (AASHTO) [3]; the goal of this kind of system is to provide the most cost-effective rehabilitations and replacements for bridges with limited funds available [4]. Many agencies and scholars have begun to research comprehensive multi-infrastructure optimization. They consider the overall transportation infrastructure as one kind of asset, and systematically manage multiple infrastructures for overall interest [5,6]. In 1999, the Organization for European Cooperation and Development Working Group released a description of asset management system engineering, stating that the objects of asset management were all components of the road network, and through comprehensive management of limited resources it could reduce overall cost and improve the quality of management and the decision-making process. In 2002, the AASHTO issued a transportation asset management guide, which defined the task and framework of asset management and emphasized integrated management by using system theory [9]
