Railway track inspection using GPR
Ž . Swiss Federal Railways SBB inspect their railway tracks at regular intervals. The first step of track renewal planning is a geotechnical study. Inspection is focused on the thickness of the ballast, on subsoil material penetrating upwards into the ballast and on geotechnical properties of subgrade and subsoil materials. Up to now, the inspection has been done mainly by digging trenches at e...
متن کاملResource re-allocation at network units by using of bi-level data envelopment analysis
The lack of renewable primary resources is one of the most serious challenges in recent decades. So under this circumstance, managers are looking for appropriate solutions for the optimal use of these resources to improve the efficiency of the under management units. One of the most widely used techniques in finding the optimal resource is data envelopment analysis (DEA). So in this paper, in ...
متن کاملAcceleration-Based Quality Assessment of Railway Tracks using a 2D simulation model and recorded track data
Car body acceleration is an important factor affecting track safety and ride comfort, which are two primary aspects of railway systems. Though track level is an important source of wagon body acceleration, no quantitative relation between them is available and the aim of this paper is to propose a method to address this issue. To do so, car body acceleration is determined using a 10 DOF simulat...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
