Abstract: لقد شهدت طرائق تقدير نماذج الانحدار اللامعلمي في السنوات الماضية توسعا كبيرا، ويعزى ذلك التوسع الى توصل الباحثين الى صعوبة مواكبة الطرائق المعلمية المستعملة في تقدير نماذج الانحدار بسبب المرونة المطلوبة عند تحليل البيانات سواء كانت البيانات كمية ام نوعي | In the past many years, the methods of estimating nonparametric regression models have been witnessed a significant expansion, due to the researchers reach difficulties to cope with use of the parametric methods in estimating of regression methods because of the desired flexibility during data analysis whether being qualitative or quantitative. But this expansion in the field of estimating nonparametric regression models come up with the major development in the hardware and software of computers, which leads to development of nonparametric regression methods and one of the most important methods is smoothing methods.In this research, the study takes different types of smoothing methods which include Kernel Smoothing and Smoothing Splines and their significant role in estimation of nonparametric regression models to describe the relationship between the explanatory variables and response variable. The researcher employs the concept of Robustness in the smoothing methods that have been adopted in this research, by using three types of smoothing methods which are Local Polynomial Kernel (LPK), Penalized Spline (PS) and Spline Regression (SR) which ends up with robust smoothing methods which are, Robust LPK, Robust PS, and Robust SR.Many issues may face the researcher while smoothing nonparametric regression models, such as data includes outliers. This leads to use the robust methods when smoothing the nonparametric functions. To do this certain methods of robust nonparametric regression has been used instead of some suggested methods in case of outliers exists in data. Therefore, the aim of this dissertation is to estimate the nonparametric regression model using robust smoothing methods and making comparisons between different methods. The researcher took the most useful researches deals with this subject such as robust methods that use these methods to estimate nonparametric regression model, and apply them in two fields, experimental and practical, in experimental field we use the simulation technique to have constant data that simulate the real data that use it in practical field. In practical field real data has been taken from Iraqi Stock Market especially the data about Al - Khaliej Insurance Company, the response variable represents the Close Price for Stock and the elementary variable is the Trading Volume. Also, the researcher suggested some of the most important conclusion drawn from experimental and practical fields in addition to some recommendations that can be adopted in future studies

Abstract: سعت الدراسة الى استعمال قرارات تصميم عملية الخدمة عبر بيان الاثر الذي تحمله هذه القرارات على اداء عمليات المركز التخصصي لطب الاسنان في العلوية، وبما يسلط الاضواء على الوسائل التي تساعد في تقديم افضل الخدمات للمجتمع، اذ اعتمدت الدراسة في جانبها التطبيقي | The study sought to use the service process design decisions through explaining the impact of these decisions on the operation performance of specialist Dental Centre in al - alwia , and highlights the ways that help provide better services to the community, in its applied side the study based on a set of quantitative indicators used to describe the impact of customer contact and resources flexibility and capital intensity on performance of cost , quality, speed and flexibility, by taking into account certain external influences of customer contact and internal represent in resources flexibility and capital intensity. The study adopted the case study method in the specialty Center for dental/ al - alwia as one of the centers of the Baghdad Health Directorate/Rusafa, data were collected from the wrote - down data in records of patients and doctors and equipment used for the six working units within the Centre. The study has concluded a set of conclusions was notably the existence of bottlenecks in some periods as a result of sudden increases in numbers of patients because of the reliance on assumption estimates by doctors in appointing future appointments for patients, and then no mechanism by which to maneuver between doctors in the units where this bottleneck occurs, in addition to that there were several manipulations that can be made for each doctor that can utilize from doctors in units that have a surplus in Units that suffer from a shortage of doctors. The study was ended with practical recommendations highlighted the reliability of the average immersed in the communication process that occur between patient and doctor appointments for treatment rather than relying on subjective estimates by doctors, as well as the possibility of utilizing of the flexibility of the size, the number of patients as the basis on which scheduling doctors into units that leading to high performance of specialty Center, also the possibility of redeployment of available equipment in the capital - intensity units such as the teeth roots unit and oral and dental surgery to units of Less capital - intensity such as a dental renovation
