But the outsourcing experience ofrnWegagen bank S.c is faced different Weaknesses such as; Poor potential of the service providers,rnstaff members...
Supply Chain Management is crucial aspect of disaster relief operations as it deals withrngetting relief supplies needed from the source to the beneficiaries with the aim of saving lives.rnThe challenges of supply chain management prevent the humanitarian organizations fromrnmeeting their...
Transportation is the movement of persons or goods from one place to another. The needrnfor the conveyance of goods arises from the fact that they often produced in areas far fromrnthe place where they are needed. Therefore, mobility of people as well as transportation ofrngoods from place to place...

As countries of the world becomes more and more integrated through trade, there is a needrnfor efficient logistic system, in which customers who are interested in products manufacturedrnin another location can quickly find it at low cost. Ethiopia is among the fastest economicrngrowth in the world,...
Ethiopia’s international trade is regulated by the Ethiopian Customs Commission (ECC) andrnother governmental authorities, namely, the Ethiopian Food and Drug Authority (EFDA) thatrnregulate import & export of drugs, medical supplies or instruments. The custom-clearancernprocess is mandatory...
Logistics is part of the supply chain that plans, actualizes, and controls the practical, compellingrnstream and capacity of stock, organizations, and related data between the point of root and thernpoint of utilization in organize to meet customers’ prerequisites. Logistics management is...
In this paper we shall present the basic theory of Sturm-Liouville boundary value problem (BVP) together with a discussion of some of the powerful methods that are used to solve the Sturm-Liouville boundary value problem (SLBVP). Especially the paper focuses on Eigen values and Eigen functions of...
Elevated rail transportation has the advantage that with limited construction time a more open and lighter space below the structure can be realized, which is crucial to keep cities accessible. This study is interested in one of the elevated railway superstructure type, cast- in-situ posttensioned...
Different studies show that production and installation of ballast had considerable cost during the construction of ballasted track. The main objective of this research was to find and identify effective techniques of recycling/processing Ethiopian old railway ballast to its valuable form. The...
Due to the difficulty to analyze all failure modes of complex microprocessor based systems, it is risky to use those devices for a safety-critical Automatic Train Control system. A means to guarantee safety is a must in a microprocessor based train control systems. In this paper, the design and...
The general objective of this thesis is to analyze effect of change of wheel and rail profiles on contact fatigue stress using analytic and finite element softwares. The wheel rail contact condition is modeled assuming two general quadratic surfaces. The formulation in this study aims primarily at...
Train scheduling is the process of timetabling and train assignment along a given train network.rnThe key objective of this project is to design an efficient train scheduling of Addis Ababa LightrnRail Transit system which minimizes passenger waiting time and operational costs withoutrnjeopardizing...
In this study, the mechanical sliding wear and corrosion resistance property of purerncopper (Cu), Cu Ag and Cu Ni Si Cr overhead contact wire were investigated by a pinon-rndisc Tribometer with mechanical and electrochemical Measurement. The copperrnalloys were prepared in the form of pin are...
The aim of this study is to study and improve the aerodynamic performance (drag coefficient, lift coefficient, etc.), to reduce the energy consumption and checking the operational safety of the train against cross wind. The area of the study mainly concentrated on the frontal aerodynamic drag...
Fretting in railway transportation results usually on the contact areas (fitting zones) of wheelsrnand axles due to repeated relative oscillatory movement of small amplitude which leads to thernformulation of cracks. The wheel seat of the axle is the weak zone for fatigue with the impactrnof...
Regenerative braking system is a system which converts mechanical energy tornelectrical energy during braking action. It is an important system for the vehicle suchrnas hybrid and electric train. This paper which mainly concerned about the potential ofrnregenerative braking system on the reduction...
This paper deals with the problem of finding an optimum site for a railway station,rnsimultaneously it is intended to investigate, analyze and evaluate the Ethiopian railwayrnstation site selection using the method of Analytic Network Process (ANP). The paperrnidentifies five major criteria: (1)...
