يتناول البحث بالدراسة و التحليل مسألة تصميم خطط المعاينة الإحصائية بالمواصفات و استخدامها في مراقبة و ضبط جودة المنتجات الصناعية في ضوء العلاقة بين المنتج و المستهلك، و ذلك بفحص كميات معينة من الإنتاج بالاعتماد على معايير محددة مسبقاً بهدف الحكم على قابلية الدفعة في الوصول إلى مستوى الجودة المقبول أم لا. و ينطوي مفهوم معاينة القبول على فحص المواد و الأجزاء ذات المصدر الخارجي, و فحص الإنتاج في أجزائه المختلفة, و الفحص النهائي للمنتج من قبل مستهلك أو أكثر و ذلك باستخدام (MIL-STD-105E) و النظام الأمريكي (Dodge&Romin) المتعلق بخطط المعاينة الإحصائية، و يوضح البحث في إطار ذلك كيفية تصميم خطط المعاينة الإحصائية نظرياً و عملياً لضبط جودة المنتج الصناعي و تطبيقها في ضبط جودة منتجات معمل جود لتجميع الأدوات الكهربائية بالاستعانة ببرنامج (SPSS) الاحصائي. و يخلص البحث إلى نتائج تؤكد افتقار الشركة المدروسة لتطبيق التقنيات الإحصائية في ضبط الجودة و اقتصارها على قياس خصائص جودة الإنتاج معملياَ دون وجود طريقة علمية واضحة في فحص الدفعات كتصميم خطط المعاينة الإحصائية، و باعتبار أن شركة جود حاصلة على شهادات مقاييس الجودة السورية و الأوروبية، فكان لابد من توصية الشركة بتطبيق تقنيات المعاينة الإحصائية العلمية في مراحل الإنتاج جميعها، و تدريب العاملين على تطبيقها بالاستعانة بمتخصصين في مجال الجودة مع وضع خطط تبين مكان و زمان إجراء المعاينة ، و تحديد نقاط المعاينة و الفحص في مختلف المراحل الإنتاجية بهدف ارتقاء الشركة بمنتجاتها، و تقديم منتجات خالية تقريباً من العيوب ،مما يؤهل الشركة للمنافسة في الأسواق الخارجية، و ليس المحلية.
This research deals with the study and analysis the issue of planning and designing statistical sampling plan in specifications and how to use in monitoring and control industrial products quality in the light of the relationship between the producer and the consumer by examining certain quantities of production based on criteria pre defined in order to judgement on the batch viability to reach an acceptable quality level or not. The acceptance preview concept involves on examination of materials and parts of the external source, product examination in its different parts and final examination for the product by one customer or more, by using American system (MIL-STD-105E) and tables of (Dodge and Roming) which related with statistical sampling plans. This research shows theoretical and practical how to design statistical sampling plans to adjust the industrial products quality and its application in products quality control of Jood company for assembling electrical tools using statistical program (SPSS). The study concludes to results confirm that the company doesn't have an application of statistical techniques in quality control and limited to measuring the output quality characteristics in the laboratory without a clear scientific method in examine batches such as designing statistical sampling plan. Jood company has certificates of Syrian and European standards of quality control so it had to be a recommendation for the company in application the scientific statistical sampling techniques in all production stages and training the staff on its application using specialists in the field of quality with plans showing the place and the time of doing sampling and determine sampling points in different production stages in order to promote the company with its products and provide products almost free of defects which qualifies the company to competition in foreign markets, not local.

This research deals with study and analysis the issue of adjust and control the production process by using the Quality Control Charts (Control Panels) for variables , in order to measure products quality during production process , by knowing deviat
ions amount occurring in production process , causes, time and place deviation then take appropriate corrective actions.
the quality control charts show graphic measurements over time and show the lower, central, and upper limits of the process that we want to control and quality control in order to distinguish between natural changes that caused by general reasons inherent in the process and the changes that caused by specific reasons.
The research focuses on kinds of Quality Control Charts, the case have been applied on Jood Factory for assembly electrical tools, such as Control Charts for variables which includes Average chart ( X ̅- chart ) , standard deviation chart (s ̅ – chart), range chart
(R – chart), and units chart (X– chart), the control lines were drawn by using SPSS program.
The research concludes realistic results confirm that the company doesn't have an application of statistical techniques in quality control such as Quality Control Charts and there isn't clear scientific method according to athletic basis followed in process control.
Jood company has certificates of Syrian and European standards of quality control so it had to be a recommendation for the company related to use statistical control charts in all production stages , and put periodic developmental specialist training programs in quality control field with the need to include a statistical cadre to staff working in the company, and the importance of measuring process capability to make sure of its abilityto achieve quality within the specified standards, and use control limits of six standard deviation about process average.
This study concentrates on two basic problems:i)- Increasing of power
efficiency in Industrial premises to reduce the energy needed for product
unit without any impact on the production level .
To achieve this goal, lighting system should be opera
ted in a certain
condition, capacitor banks for power factor improvement should be
installed, and energy losses of distribution transformers should be reduced.
This paper tests the relationship between economic growth and human
development using annual data from Syria for the period 1970-2000. This
period is chosen for two reasons; firstly because of its political and economic
homogeneity which is conduc
tive to arrive at accurate results and secondly
because the significant changes in the Syrian government's policies in the
fields of education and health like the opining for the first time of private
universities and open learning programs and the involvement of the private
sector in providing health services and health insurance.
These papers aim to study the estimation of the simple linear regression equation
coefficients using the least square method at different sample sizes and different sampling
methods. And so on, the main goal of this research is to try to determine
the optimum size
and the best sampling method for these coefficients. We used experimental data for a
population consist of 2000 students from different schools all over the country. We had
changed the sample size each time and calculate the coefficients and then compare these
coefficients for different sample sizes with their coefficients of the real population; and the
results have been shown that the estimation of the linear regression equation coefficients
are close from the real values of the coefficients of the regression line equation for the
population when the sample size closes the value (325). As it turns out that the Stratified
random sampling with proportional distribution with class sizes gives the best and most
accurate results to estimate linear regression equation with least square method.
Housing is considered void that protects the rights of the external factors and provide
him with the necessary requirements, and depending on the quality and the pioneers of
global research in this range, the most important measure of the quality o
f the residential
building is the degree of satisfaction achieved by the building of the user , Since users are
the first to be affected by the decision of the house's design to understand they have the
right to participate in decision-making in the design process.
The research presents a field study on the posts in the design of residential buildings
in the city of Latakia in order to check the impact of user participation on the quality of the
residential building designed by measuring the relationship between the degree of user
participation and the amount of satisfaction from their homes.
The research found that the user has the participation of a major role in raising the
quality of the design of the apartment building in the city of Latakia in line with available
resources.
