Transportation problems are considered as a type of operation research problems. In fact, they deal with scheduling transportation of goods from their source to delivery sites in the minimum cost.

Such problems can be solved by the available traditional methods, which include; North-West corner, Least cost and Vogel’s method. As well as if this transportation problem is considered as a linear program it can also be solved by using Simplex method

The goal of the present study is to compare different research methods to provide the optimal and minimum cost.

This study was applied to resolve a transportation problem related to land Transportation Company, which had big convey for carrying goods of different weights among various governorates within the country.

At the beginning the problem was solved by applying the least cost method to obtain the primal solution, and then test it to find the optimal solution by modified distribution method (Ui, Vj). Secondly, as the problem is considered as a linear program model, it was solved by Simplex method. Lastly a new modification that was using both Dual theory related parameters and modified distribution method, and design a new mathematical model [2]. Then it was solved by Simplex method.

The total cost in both the first and second method were similar (i.e.) (the least cost method and direct application of Simplex method) whereas, the results in the last modified method was significantly lower. This indicates that the new relation between Dual theory and Modified distribution method provides better and efficient way to obtain optimal solution with less cost for such problem. This architectural is good in correcting the detail of Simplex solution to achieve more efficient solutions.

Using Public and Private Cloud Computing in developing the Evaluation System of annual employees' performance at Iraqi Universities: A comparative study
...Show More Authors

Abstract

Business organizations are using the technological innovations like cloud computing (CC) as a developmental platform in order to improve the performance of their information systems. In that context, our paper discusses know-how in employing the public and private CC to serve as platforms to develop the evaluation system of annual employees' performance (ESAEP) at Iraqi universities. Therefore, we ask the paper question which is “Is it possible to adopt the innovative solutions of ICTs (Like: public and private CC) for finding the developmental vision about management information systems at business organizations?”. In addition, the paper aim

Using Infographics as An Educational Technology Tool in EFL Writing: University of Baghdad Case Study
...Show More Authors

Infographics have the capability to organize and display information in a way that is easy for viewers to retrieve and make observations. While infographics have been successful in various fields, their potential benefits in composition writing have not been explored. The primary objective of this study is to investigate the perspectives of Iraqi EFL students who used infographics as an educational technology tool in composition writing, and to identify how gender influences students’ performance when using infographics in EFL writing classes. The significance of this study lies in its integration of infographics as an educational technology tool for teaching writing, aligning with the current trend of technology integration in ed

(Estimation and Analysis of the Cobb-Duglas Production Function for the Rail Transport Sector in Iraq for the Period 1990-2016 using the ARDL Model)
...Show More Authors

Abstract:

Since the railway transport sector is very important in many countries of the world, we have tried through this research to study the production function of this sector and to indicate the level of productivity under which it operates.

It was found through the estimation and analysis of the production function Kub - Duglas that the railway transport sector in Iraq suffers from a decline in the level of productivity, which was reflected in the deterioration of the level of services provided for the transport of passengers and goods. This led to the loss of the sector of importance in supporting the national economy and the reluctance of most passengers an

Mixture experiments are response variables based on the proportions of component for this mixture. In our research we will compare the scheffʼe model with the kronecker model for the mixture experiments, especially when the experimental area is restricted.

     Because of the experience of the mixture of high correlation problem and the problem of multicollinearity between the explanatory variables, which has an effect on the calculation of the Fisher information matrix of the regression model.

     to estimate the parameters of the mixture model, we used the (generalized inverse ) And the Stepwise Regression procedure

The study of cuneiform texts is very important for finding out the ancient history of Iraq and its civilization, as well as the close relation among languages, especially Semitic, the mother language to which both Akkadian and Arabic belong, the matter that clarifies the linkage among them. The Akkadian language is among these Jazri (a Semitic branch) languages, besides Arabic. It is the most ancient one. It consisted of a lot of genuine linguistic rules derived from the mother Jazri language. Contrastive Akkadian studies approved these linguistic rules. Due to the close linkage that relates Akkadian language to its sister Arabic , as they both relate to the same family, the researcher an verbs and compared them with studied aspects and moo
