استخدام Win.Q.S.B. لإصدار خطة إنتاجية
...Show More Authors

المقدمة

بفضل التقدم الذي حصل في الحاسبات في العقد الأخير والذي انعكست آثاره على البرامج الجاهزة اعتبرت المشكلة التي في حدود بضعة آلاف من المتغيرات والقيود من المشاكل الصغيرة إذ تم حل مشاكل بعشرات الآلاف أو مئات الآلاف من المتغيرات المستمرة حلا مناسبا.وبفضل التقدم التكنولوجي للحاسبات وسرعة معاملتها للبيانات والمعادلات تم بناء برامج جاهزة لأساليب بحوث العمليات ومعالجة المشاكل الإدارية، هذه البرامج الجاهزة تساعد في سرعة التطبيق والتركيز على صياغة المشكلة وأسلوب معالجتها وتحليل حساسيتها لبيان التأثيرات المحتملة على الإنموذج.

ولغرض توفير الجهد والوقت وإتاحة فرصة أكبر للالتفات إلى المراحل المهمة الأخرى لمعالجة المشكلة قيد الدراسة جاءت الفكرة في استخدام البرامج الجاهزة لإصدار خطة إنتاجية فبعد دراسة الخطة الإنتاجية لشركة السلام والاطلاع على سير العملية الإنتاجية لمنتجاتها العشرة لاحظنا إن عملية التخطيط تتم يدويا باستخدام أساليب رياضية بسيطة وسطحية وبصورة تعتمد على الاجتهاد والخبرة الشخصية ومع الاعتزاز بتلك الخبرات في مجال تخطيط الإنتاج إلا إنها لا تواكب التطور الذي يشهده العالم من حيث تطبيق الأساليب العلمية الحديثة فالاعتقاد السائد هو عدم إمكانية تطبيق الأساليب العلمية واستخدام البرامج الجاهزة عمليا في تخطيط الإنتاج، وأحد أسباب ذلك هو التغيرات المفاجئة سواءا في طاقاتها المتاحة أو في كمية الطلب أو كمية الخزين للمنتجات ومن هذا المنطلق جاءت مساهمة البحث في استخدام البرنامج الجاهز W i n .Q.S.B لإصدار خطة إنتاجية لشركة السلام حيث تم توضيح آلية استخدام البرنامج وفي كيفية إدخال المشكلة قيد الدراسة إلى البرنامج بعد صياغتها وفي كيفية إدخال أو حذف التغيرات التي تطرأ على الأنموذج الرياضي وعن تفاصيل طرق حل المشكلة قيد الدراسة وعن تفسير نتائج الحل وكيفية توضيحها بمخططات ورسوم بيانية ببعدين أو ثلاثة أبعاد.

هذا الأنموذج ومن خلال البرنامج Win.Q.S.B والذي يعمل ضمن بيئة Windows له القابلية على استيعاب التغييرات الآنية والمستقبلية التي تمر بها شركاتنا ومصانعنا نتيجة لتغير الظروف المحيطة بها من وقت لأخر والتفاعل معها في أي وقت من الأوقات وبسرعة كبيرة كما يمكن تطبيق هذا الأنموذج في مصانع أخرى إذا ما أريد تخطيط إنتاجها مع إجراء بعض التغييرات لقيم أو معاملات ثابتة في الأنموذج.

"RUF procedures forgetting the best subset linear regression model"
...Show More Authors

The purpose behind building the linear regression model is to describe the real linear relation between any explanatory variable in the model and the dependent one, on the basis of the fact that the dependent variable is a linear function of the explanatory variables and one can use it for prediction and control. This purpose does not cometrue without getting significant, stable and reasonable estimatros for the parameters of the model, specifically regression-coefficients. The researcher found that "RUF" the criterian that he had suggested accurate and sufficient to accomplish that purpose when multicollinearity exists provided that the adequate model that satisfies the standard assumpitions of the error-term can be assigned.

The Study of Ability of Local Ninivite Rocks in Purification of Drinking Water
...Show More Authors

This study is conducted to verify the efficienecy of local Ninivite rock when used in the treatment of drinking water in plants operating currently in the country in order to develop the situation of these stations to cope with the increase in population. Also, this will limit the pollutian which are increasing in the country's rivers.

(Euphrates and Tigris). These rivers are the sources to feed all water treatment plants in the country. The idea is the develop or the modify these stations by replacing part of top layer of sand filters used in these stations with Ninivite rock to operate as filters composed of two medium.

Use Principal Component Analysis Technique to Dimensionality Reduction to Multi Source
...Show More Authors

This paper tackles with principal component analysis method (PCA ) to dimensionality reduction in the case of linear combinations to digital image processing and analysis. The PCA is statistical technique that shrinkages a multivariate data set consisting of inter-correlated variables into a data set consisting of variables that are uncorrelated linear combination, while ensuring the least possible loss of useful information. This method was applied to a group of satellite images of a certain area in the province of Basra, which represents the mouth of the Tigris and Euphrates rivers in the Shatt al-Arab in the province of Basra.

In this search, we examined the factorial experiments and the study of the significance of the main effects, the interaction of the factors and their simple effects by the F test (ANOVA) for analyze the data of the factorial experience. It is also known that the analysis of variance requires several assumptions to achieve them, Therefore, in case of violation of one of these conditions we conduct a transform to the data in order to match or achieve the conditions of analysis of variance, but it was noted that these transfers do not produce accurate results, so we resort to tests or non-parametric methods that work as a solution or alternative to the parametric tests , these method
