Numerical simulation of track settlements based on an iterative holistic approach

A Holistic Approach Based on MCDM for Solving Location Problems

Location decision is an integral part of organizational strategies involving many factorsthat may be conflicting in nature. This paper presents a holistic approach of the multi-criteria decisionmaking (MCDM) methodology to select the optimal location(s), which fits best for both investors andmanagers. A case study is also provided to illustrate the application of the proposed holistic approach....

A holistic Approach on the Simulation of Rotary-Friction-Welding

The contribution deals with a new holistic approach on the process simulation of Rotary Friction Welding (RFW). The main focus in this regard is on the proper determination of process parameters for new pairs of weld partners in a complete virtual manner. Basis of the simulation is a Carreau fluid material law coupled with the heat transfer problem. The plastic deformations of the flash are map...

An iterative approach for estimation of efficiency by weighted distance

An Experimental and Numerical Study on the Effect of Different Types of Sleepers on Track Lateral Resistance

Lateral resistance of railway track is one of the most important parameters in lateral stability. This parameter depends!on the conditions of different components of ballasted railway track (such as density of ballast layer, sleeper spacing, type of sleeper, etc.). From this perspective, type of sleeper has an important effect on lateral resistance. However in some conditions, in technical and ...
