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.

Using the Logistic Regression Model in Studding the Assistant Factors to Diagnose Bladder Cancer
...Show More Authors

The cancer is one of the biggest health problems that facing the world . And  the bladder cancer has a special place among the most spread cancers in Arab countries specially in Iraq and Egypt(2) . It is one of the diseases which can be treated and cured if it is diagnosed early . This research is aimed at studying the assistant factors that diagnose bladder cancer such as (patient's age , gender , and other major complains of hematuria , burning or pain during urination and micturition disorders) and then determine which factors are the most effective in the possibility of diagnosing this disease by using the statistical model (logistic regression model) and depending on a random sample of (128) patients . After

The use of GIS in the analysis of existing condition of spatial distribution of wire communications network in the city of Baghdad
...Show More Authors

The increasing efficiency of the telecommunications network in the city contributes to the increase in spatial interaction between activities (to influence and mutual influence) This study is based on the idea that the upgrading of telephone services provided to citizens are done exclusively through the growth and development of all levels of the service using advanced technologies to know the problems and appropriate solutions in short time and less cost. Thus, crystallized the objectives of the study which was built for the importance of GIS in the planning of services in general, and infrastructure services, in particular, including telephone services, which is represent a point of contact between individuals on the one hand a

Can diode laser avoid pilonidal sinus excision by the conventional operation?
...Show More Authors

Background: Pilonidal sinus is a recurrence pathology that affects the gluteal area, cleft part of it.  It affects many parts but mainly the sacral area and may present with various forms; from the asymptomatic cyst to severe infection in a form of painful abscess or sinus. The treatment of pilonidal sinus ranges from observation with good hygiene to excision of the sinus left wide incision. Recurrence may follow the excisional procedure and may need more operations. Many conservative ways had been used for the management of the sinus; laser (phototherapy) is one kind that may use. this paper aims to test the efficiency of the laser (diode 980nm) in the treatment of the sinus. material:

Using Iterative Reweighting Algorithm and Genetic Algorithm to Calculate The Estimation of The Parameters Of The Maximum Likelihood of The Skew Normal Distribution
...Show More Authors

Excessive skewness which occurs sometimes in the data is represented as an obstacle against normal distribution. So, recent studies have witnessed activity in studying the skew-normal distribution (SND) that matches the skewness data which is regarded as a special case of the normal distribution with additional skewness parameter (α), which gives more flexibility to the normal distribution. When estimating the parameters of (SND), we face the problem of the non-linear equation and by using the method of Maximum Likelihood estimation (ML) their solutions will be inaccurate and unreliable. To solve this problem, two methods can be used that are: the genetic algorithm (GA) and the iterative reweighting algorithm (IR) based on the M

This research includes the study of dual data models with mixed random parameters, which contain two types of parameters, the first is random and the other is fixed. For the random parameter, it is obtained as a result of differences in the marginal tendencies of the cross sections, and for the fixed parameter, it is obtained as a result of differences in fixed limits, and random errors for each section. Accidental bearing the characteristic of heterogeneity of variance in addition to the presence of serial correlation of the first degree, and the main objective in this research is the use of efficient methods commensurate with the paired data in the case of small samples, and to achieve this goal, the feasible general least squa
