Ranking & Optimization

Ranking & Optimization

Ranking and optimization plays an important role in any economic evaluation, in the case that more than one project is competing for limited available funds. Our knowledge of ranking and optimization is based on economic and mathematical theories, real-life constraints (e.g., budgetary, institutional, and geographical), and statistical analysis. We use optimization for quantifiable benefits (e.g., the value of time, or the production cost of electricity), and ranking for variables for which monetization will be fraught with subjective factors and valuations. All Pavement Management Systems (PMS) include either ranking or optimization, or oftentimes both, based on their usage of different types of data.


Economikr’s comparative advantage is in our in-depth understanding and ability to apply several kinds of ranking and optimization procedures, and apply them to local client requirements. These factors include budget constraints, institutional, geographical, social and environmental impacts as clients adopt different approaches to decision-making. Our expertise and experience helps our clients make better decisions, deliver more effective projects, and demonstrate their value.

Sample Projects 

Pavement Management System of Rural Roads in the Dominican Republic

This project, funded by the IDB (Inter-American Development Bank) contained the following elements: development of an economic methodology for transport sector evaluation and analysis, creation of a socio-economic ranking procedure and poverty indices based on economic potential, social, and other factors. The procedures developed in the course of this project were used to allocate budgets under a set of budgetary ceilings, based on IBC (Incremental Benefit Cost) multi-year optimization.

Nigerian Interurban Pavement Management System (PMS)

Under the auspices of the World Bank, this DBOMT (Design, Build Operate Maintain Transfer) project was considered to be on of the first PPP (Public Private Partnership) projects in Africa. The project’s focus was on economic optimization under three types of constraints (budgetary, geographical, and institutional), beyond typical year-by-year constraints. Economic optimization for this project was based on IBC (Incremental Benefit Cost) methods, incorporating both efficiency frontiers and multi-year analyses.

Development of a Budgeting System for Funding Interurban and Urban Roads in El Salvador

Supported by the IDB (Inter-American Development Bank), this project was dedicated to developing and calibrating engineering and economic models for road transport projects, from heavily trafficked paved roads, down to dirt roads. The results of these models were culminated in a budget optimization method for periodic road maintenance activities and prioritization of routine maintenance activities. Three types of optimization were deployed: standard budget optimization, agency cost optimization, and reverse optimization (e.g., determining costs of raising the road network to a given user-defined level).
