On Numerical Estimation Of Performance Robustness Of Transportation Networks
نویسندگان
چکیده
The limited economic and spatial resources require a careful planning of investments, so that achieving the most accurate knowledge of the performances of any proposed solution is a problem of worth importance. A possible solution to this problem is provided by sensitivity analysis to evaluate their robustness to uncertainties. Then, in this paper, traffic simulations will be used to evaluate, by means of a proposed sensitivity analysis approach, the robustness of several interventions planned for the real case study consisting of the transportation network around the seaport of Genoa in Italy.

Estimation of Reconstruction Cost and Traffic Functionality Relating to Roadway Transportation Lifelines after Natural Disasters
Earthquakes are among those natural hazards which may lead to disruption in the function of arterial traffic routes. Road networks are particularly vulnerable, due to their geographical dispersion, extensive functions and structural reliance on favourable geophysical conditions. Traffic functionality after a natural disaster and the repair/rehabilitation cost of roads are crucial considerations...
متن کاملRobust uncapacitated multiple allocation hub location problem under demand uncertainty: minimization of cost deviations
The hub location–allocation problem under uncertainty is a real-world task arising in the areas such as public and freight transportation and telecommunication systems. In many applications, the demand is considered as inexact because of the forecasting inaccuracies or human’s unpredictability. This study addresses the robust uncapacitated multiple allocation hub location problem with a set of ...

In some statistical process control applications, the combination of both variable and attribute quality characteristics which are correlated represents the quality of the product or the process. In such processes, identification the time of manifesting the out-of-control states can help the quality engineers to eliminate the assignable causes through proper corrective actions. In this paper, f...
متن کاملThe Assessment of Applying Chaos Theory for Daily Traffic Estimation
Road traffic volumes in intercity roads are generally estimated by probability functions, statistical techniques or meta-heuristic approaches such as artificial neural networks. As the road traffic volumes depend on input variables and mainly road geometrical design, weather conditions, day or night time, weekend or national holidays and so on, these are also estimated by pattern recognition te...
متن کاملTWO-STAGE METHOD FOR DAMAGE LOCALIZATION AND QUANTIFICATION IN HIGH-RISE SHEAR FRAMES BASED ON THE FIRST MODE SHAPE SLOPE
In this paper, a two-stage method for damage detection and estimation in tall shear frames is presented. This method is based on the first mode shape of a shear frame. We demonstrate that the first mode shape slope is very sensitive to the story stiffness. Thus, at the first stage, by using the grey system theory on the first mode shape slope, damage locations are identified in shear frames. Da...
