Downstream humanitarian supply chain management is one of the major functions in thernsupply chain management practice since it covers almost half of the operation performedrnin the humanitarian supply chain management. The main objective of this study was tornexamine the performance of downstream...
The objective of this study is to explain the effect of ACE on Air Cargo TerminalrnWarehouse performances in the case of Ethiopian Airlines Group Cargo section. Arnsystematic literature review was made on ACE operating system and warehousernperformance to identify the explanatory or independent...
This project work concentrates on the ideal theory of subtraction algebras. We start it with lattice, semi-lattice, Boolean algebra, supremum and infimum of a set. The main body of the project recapitulates subtraction algebra and ideal of subtraction...
Previous studies published thoughts that dry port container handling service Practice can bernaffected by many factors and this study revealed that factors such as insufficient port yardrnequipment, dwell time, container cargo volume and truck turnaround time, custom clearance,rnlimited storage...
Vaccines are essential health commodities which need their own specific supply chain system withrnstorage of 2 oC to 8 oC from manufacturing up to final use. It is recommended and critical that theyrnshould be kept in appropriate temperatures during transport, storage and use. The purpose of...
The objective of this study was the effect of strategic sourcing on the organizational performancernwhich as operational performance in Ethiopian Shipping and Logistics Service Enterprise. Thernstudy used descriptive research design that was used to achieve the purpose of the study. Thernstudy had...
Multi-level programming is characterized as mathematical programming to solve decentralized planning problems with multiple decision makers in a hierarchical organization. They become more important for contemporary decentralized organization where each unit or department seeks its own...
The Central idea of iteration theory is the division of the complex plane in to Fatou set and Julia sets. Especially the paper focuses on properties of Fatou sets of iteration of rational function. We devoted much time on the Fatou and Julia sets due to their particular importance to express...
This seminar report is devoted to the study of harmonic functions on disc and upper half plane. These functions are closely connected to analytic functions since the real and imaginary parts of analytic function are harmonic functions. The study of harmonic functions is important in physics and...
The set covering problem (SCP) is a fundamental problem in the class of covering problems.rnGiven a finite set and a family , ,…, rn of subsets of rn . . , , rn1,2,…, the set covering problem is to find the minimum cardinality 1,2,…, suchrnthat ...
The plan for the operation of trains on the Addis Ababa Light Rail Transit (AALRT) is based onrna fixed interval of riding between stations. Fixed riding time between stations will have the effectrnof inefficient energy consumption by the trains. Furthermore, the transportation capacity of...
Electro-pneumatic braking system (epbs) components can be frequently used in anyrncommercial automobile vehicles regardless of their size of outputs. Their difference is in thernamount of longitudinal force developed inside these components according to the size of thernautomobile. The simulation...
I introduced more of the combinatorial interpretations of Catalan numbers using different techniques ( interpretations) like enumeration of lattice path, ordered trees, binary trees ,etc their one to one correspondence using different theorems lemmas and rules and also an interpretations of k-th...
The manual system of preparing timetable in railway system with complex network line is very timernconsuming and usually ends up with various train conflicting either at some stations or at some substationsrnhaving more than one train at a time. To overcome all these problems it is important...
An electric transmission in an electrified railway system must provide power transmission within the voltage limit at safe and quality conditions. Therefore, system analysis within the traction power system is vital to the design and operation of an electrified railway. Loads in traction power...
The implementation of Light Rail Transit System (LRTS) as an integrated form of public transportation, with the rail corridor running through city centers and connecting major commercial centers, presents a unique electromagnetic coupling scenario between sensitive installations and the dc magnetic...
In rapidly developing cities automobile ownerships and their utilization isrnincreasing and accordingly the problem of traffic congestions quickly go fromrnbad to worse. It is, therefore, necessary for these cities to construct and operaterna transit system. The basic question that must be...
It is easy to point out that any function of a complex-variable can bernconsidered as a mapping from one complex plane into another. A great dealrnof attention is devoted to the study of holomorphic functions. The reason forrnthis is that many problems from the theory of holomorphic functions can...
