Effect Of Using Quantitative Methods Of Demand Forecasting In Improving Of Supply Chain Performance:" Case Study In One Of An Industerial Organization"
...Show More Authors

Objecte The study aims to test the effect of using the appropriate quantitative method of demand forecasting in improving the performance of supply chain of the aviation fuel product ( The study sample), One of the products of the Doura refinery (The study site), By testing a set of quantitative methods of demand forecasting using forecasting error measurements, and choosing the least faulty, most accurate and reliable method and adept it in the building  chain.

Is the study of problem through a starting with the following main questions:

"Does the chosen of the appropriate quantitative method for demand forecasting affect the performance of supply chain of the aviation fuel product in the refinery (site the study)?"

The importance of study shows through investment all opportunities sales and reduce the opportunities

Adopted the study used the case study methodology to study the methods used in the Refinery to demand forecast for aviation fuel and analyze the supply chain, of the product  then test a set of quantitative methods to forecast  the demand of the sample of the study and choose the best method using predictive error measurements, to  depending it in the building  of supply chain proposed by the study, And then compare the performance of the current and proposed chain using a set of financial and quantitative measures most important (quantity of production, quantity of shortage deficit, total costs, revenues, profits) .

The study reached a set of conclusions the light of results the most important that the measurements adopted in the comparison of the two chain have indicated that the supply chain proposed by the study the current excelled supply chain of aviation fuel.

The research aims to recognize the impact of the training program based on integrating future thinking skills and classroom interaction patterns for mathematics teachers and providing their students with creative solution skills. To achieve the goal of the research, the following hypothesis was formulated: There is no statistically significant difference at the level (0.05) between the mean scores of students of mathematics teachers whose teachers trained according to the proposed training program (the experimental group) and whose teachers were not trained according to the proposed training program (the control group) in Pre-post creative solution skills test. Research sample is consisted of (31) teachers and schools were distribut

The facilities layout are among the most important of the most influential factors in the efficiency of the production system, and represents the systematic layout of the various work centers, tools, persons, and other auxiliary services within the factory. Careful selection of the technique that would be used in Re-layout, represents an important step in reaching to the optimum layout that keeps on reducing handling costs and reduce unnecessary movement of materials, as well as the regularity and functioning of the flow of materials through the facilities. The research aims to propose a new layout of (Al-M'ammon Factory / The General Company for Vegetable Oils Industry), and then re-layout according to the new propose layout by using of te
