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.

''The use of factor analysis to identify the leading factors to high blood pressure.''A field study in Baghdad hospitals
...Show More Authors

Abstract :

    In view of the fact that high blood pressure is one of the serious human diseases that a person can get without having to feel them, which is caused by many reasons therefore it became necessary to do research in this subject and to express these many factors by specific causes through studying it using (factor analysis).

  So the researcher got to the five factors that explains only 71% of the total variation in this phenomenon is the subject of the research, where ((overweight)) and ((alcohol in abundance)) and ((smoking)) and ((lack of exercise)) are the reasons that influential the most in the incidence of this disease.

Effect Use of Two Chemical Compounds Sodium Nitrate and Sodium Silicate as Corrosion Inhibitor to Steel Reinforcement
...Show More Authors

Corrosion of steel reinforcement is one of the biggest problems facing all countries in the world like bridges in the beach area and marine constructions which lead to study these problems and apply some economical solutions. According to the high cost of repair for these constructions, were studied the effect of using kind of chemical compounds sodium nitrite(NaNO2) and sodium silicate(Na2SiO3) as corrosion inhibitors admixture for steel bars that immersed partially in electrolyte solution (water + sodium chloride in 3% conc.) (Approximately similar to the concentration of salt in sea water). The two inhibitors above added each one to the electrolyte solution at concentrations (0.5%, 1% and 2%) for both

Evaluating the utility of plasma Atherogenic Index among several atherogenic parameters in patients with chronic renal Failure on maintenance hemodialysis
...Show More Authors

Background: Patients with chronic renal failure undergoing longterm hemodialysis (HD) are prone to atherosclerosis and at increased risk of developing cardiovascular diseases.
Objective: The objective of this study is to compare atherogenic index of plasma (AIP) in predicting the risk of cardiovascular disease (CVD) in patients with chronic renal failure (CRF) on regular hemodialysis, when associated with other chronic diseases.
Patients and methods: A total of forty male patients with CRF on hemodialysis, matched in, age, body mass index BMI, and duration of hemodialysis were enrolled. They were grouped as group 1 (G1) includes eleven subjects with CRF without (hypertension and / or diabetes) groups 2 (G2) fourteen CRF subjects wi

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

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:

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

Using the Critical Path Method to Find Time of Constriction for Helicopters Airport Project in the Oil Fields
...Show More Authors

This research is considered one of the important researches in Maysan Governorate, as it focuses on the construction of helicopter airport project in the oil fields of the Maysan Oil Company, where the oil general companies in Maysan Governorate suffer from the cost of transporting the foreign engineering experts and the governing equipment of sustaining oil industry from Iraq's international airports to oil fields and vice versa. Private international transport companies transport foreign engineering from the oil fields to Iraqi airports and vice versa, and other international security companies take action to provide protection for foreign engineering experts during transportation. Hence, this process is very costly.
