Material Requirements Planning for the Electric Motor in Fuzzy Environment for State Company for Electric Industries
...Show More Authors

ABSTRUCT

This research aims at examining the expected gap between the fact of planning and controlling process of production at the State Company for Electric Industries and implementation of material requirements planning system in fuzzy environment. Developing solutions to bridge the gap is required to provide specific mechanisms subject to the logic of fuzzy rules that will keep pace with demand for increased accuracy and reduced waiting times depending on demand forecast, investment in inventory to reduce costs to a minimum.

The proposed solutions for overcoming the research problem has required some  questions reflecting the problem with its multiple dimensions, which are in essence the possibility of employing fuzzy sets theory to remove high levels of uncertainty in demand, lead times , and  in the total cost of the electric motor for air coolers (consisting of fifty-six part) during the time period between (2/1/2014) and (15/1/2015), and to increase the effectiveness of material requirements planning system for achieving its goals more efficiently.

In order to answer the research questions, fuzzy time  series technique has used for estimating demand and its expected change rates.IF-THEN rules has also been used with their linguistic variables and experts opinions at the company studied after being converted to probability matrices reflecting the variation of lead times owing to demand levels fluctuations and its indicator. Furthermore, IF-THEN rules has also been used for estimating fuzzy inventory costs.

The required mathematical and quantitative analyses of research data have conducted using a number of statistical packages (Win Qsb, SPSS, Matlab).

The final results confirmed the applicability of fuzzy sets theory to reduce the effects of environmental variability facing the company studied in areas of demand, lead times and inventory costs . Moreover, it has reached to a result indicating the possibility of using  modern techniques in controlling demand and inventory fluctuations via material requirements planning system in fuzzy environment that provide a proposed solutions to the research problem and specific answers on the research questions, Research recommendations have raised the necessity of remove the vagueness and uncertainty accompanying the Iraqi production environment by employing fuzzy sets theory applications for ensuring the effective application of material requirements planning system within fuzzy environment.

The aim of the research is to identify the extent of the direct and indirect relationship of the population growth of the cities as a result of the urbanization process witnessed by the Arab region for the urban development of the city structures and their formative structures, changing the planning criteria of some cities and the extent of their changes in spatial and temporal dimensions and their relation to the standards of the western cities. In changing the concept of the modern Arab city, such as the emergence of new functional uses affecting the change in the pattern of formal formations of its urban fabric associated with its ancient morphology and distinctive human nature. The research seeks to identify the extent to which plann

Prediction of the number of births in the Governorate of Basra for the period (1998-2050)
...Show More Authors

The adoption of many mathematical concepts contributes to the construction of models of sports and the population can be interpreted to explain the movement and growth of the population lead to proper planning to manage the requirements of the population and meet their needs of providing education or providing medical services, health and others. In this study, the number of births in the Governorate of Basrah for the period (1998-2050) is estimated to be based on the assumption that the population of the visually impaired is a stable society. If the rate of growth is (0.0492), some demographic indicators are important for maintaining the average age of women at pregnancy (27.817). Each woman will give birth (3.74) female birth d

The Necessary and Sufficient Optimality Conditions for a System of FOCPs with Caputo–Katugampola Derivatives
...Show More Authors

The necessary optimality conditions with Lagrange multipliers  are studied and derived for a new class that includes the system of CaputoKatugampola fractional derivatives to the optimal control problems with considering the end time free. The formula for the integral by parts has been proven for the left CaputoKatugampola fractional derivative that contributes to the finding and deriving the necessary optimality conditions. Also, three special cases are obtained, including the study of the necessary optimality conditions when both the final time  and the final state  are fixed. According to convexity assumptions prove that necessary optimality conditions are sufficient optimality conditions.

Propagation Mechanisms for Surface Initiated Cracking in Composite Pavements
...Show More Authors

The primary objective of this study was to identify the mechanisms for the development and propagation of longitudinal cracks that initiate at the surface of composite pavement. In this study the finite element program ANSYS version (5.4) was used and the model worked out using this program has the ability to analyze a composite pavement structure of different layer properties. Also, the aim of this study was modeling and analyzing of the composite pavement structure with the physical presence of crack induced in concrete underlying layer. The results obtained indicates that increasing the thickness of the asphalt layer tends to decrease the stress intensity factor, which may be attributed to the rapidly decrease of horizontal tensile st

Signification with its different aspects constitutes various aesthetic pictures for human and nature creations over different periods of time. It was a focal around which logical thinking loops on the interpretation level of the signification movement according to its structural context expresses its hidden entities with which a human being deals according to two symmetrical levels while interpreting to attain meaning. Sense was the first passing window for the picture of signification which thought deals with. While trying to decode it and because art in general and theatre in particular are considered as the basis of creating signification through its visual and aural elements, so it was necessary to consider one of the elements of cre

The Arabic grammatical theory is characterized by the characteristics that distinguish it from other languages. It is based on the following equation: In its entirety a homogeneous linguistic system that blends with the social nature of the Arab, his beliefs, and his culture.
    This means that this theory was born naturally, after the labor of maintaining an integrated inheritance, starting with its legal text (the Koran), and ends with its features of multiple attributes.
Saber was carrying the founding crucible of that theory, which takes over from his teacher, Hebron, to be built on what it has reached. It is redundant to point to his location and the status of his book.
