Most of organizations (both national and international) have struggled with many difficulties during the past decades due to many problems, creating a negative impact on the productivity and utilization levels of many institutions around the globe, and within Libya in particular. This paper presents the current role, relevance, trends and challenges with respect of quality management applications in educational field within Libya as a case study. It outlines an overview of the current state of art to show how in the face of growing global competitiveness quality at the levels of knower, knowing and known elements of educational system using unified field of all the laws of nature, are deriving the benefits of the quality techniques. The paper also investigates the current implementation levels of Total Quality Management (TQM) as a philosophy for improving the quality levels within some academic and training institutions within Libya. A survey methodology has been applied in this research where some findings from interesting case studies are presented to show the benefits of successful TQM implementations originally developed for manufacturing industry. The paper has also pointed to areas where senior managers within the surveyed organizations should take immediate actions to achieve effective and successful TQM implementations, thereby improving their position in this competitive marketplace. arabic 17 English 115

In this paper, an orthopedic robot-assisted drilling system is presented. The system consists of a six degree of freedom robot manipulator equipped with a multi axis force/torque sensor and an electrical drilling tool attached to the robot end-effector. The purpose of the system is to enable the orthopedic surgeons to drill the patient bone using the robot manipulator and automatically detect the bone breakthrough during bone fixation process. The breakthrough is detected by measuring the forces acting on the drilling tool tip. This will reduce/eliminate the need for X-rays imaging used in traditional bone fixation. The system has been tested on sheep bone. The result has shown that, the bone drilling operation can be handled by a robot manipulator to improve the quality of the drilling operation. With this system, the bone breakthrough can be easily detected and further damage of the healthy patient tissue would be avoided. This will lead to fast patient recovery and short hospital stay.

عند تطبيق سياسات الصيانة تواجه المؤسسات الصناعية والخدمية على حدا سواء تحدى ألا وهو ماهى طريقة الصيانة المثلى والسياسة الأفضل الواجب إتباعها لصيانة النظام بالأخذ في الاعتبار التكاليف ؟ بكلمات أخرى ماهى السياسة المثلى للصيانة التي تحقق التوازن بين تقليل الأعطال والحفاظ على النظام في أحسن الظروف التشغيلية وبأقل تكلفة ممكنة للصيانة.لذلك تشكل تكلفة الصيانة دورا هاما قي عملية المفاضلة عند اختيار وتخطيط سياسات الصيانة. إن حساب تكاليف الصيانة لاى نظام من بداية تشغيله إلى نهاية عمره الافتراضي له أهمية كبيرة للمؤسسة الصناعية ، حيث يضمن لمتخذي القرار حسن التصرف في مصادر رؤؤس الأموال وهذا الأمر مهم جدا خصوصا للدول النامية نظرا لمحدودية توفر إمكانياتها . لذلك يقدم البحث نموذج رياضي مطور لتقدير التكاليف الإجمالية لسياسات الصيانة المتبعة أو المقترحة لنظام ما على طول العمر الافتراضي له ، تقدير عدد الأعطال التي يتعرض لها النظام، تقدير تكلفة المواد المطلوبة لعمليات الصيانة ، تقدير العدد الأمثل لمرات إجراء الصيانة الوقائية بكل فترة من فترات عمر النظام ، ومن خلال البحث نقوم بدراسة وتحليل تأثير العناصر المختلفة للصيانة على معايير الأداء . أيضا يعطى النموذج الرياضي المطور الوقت الأمثل لإجراء العمرة لمعدات النظام بدلا من السياسة التقليدية المتبعة ببعض المؤسسات الصناعية في الدول النامية والتي تعتمد فقط على إجراء عمرة لمعدات النظام بعد فترات زمنية ثابتة بغض النظر عن حالة النظام ومدى احتياجه فعليا لتجديد معداته .ويدعم البحث بدراسة تحليلية وعملية لنظام محطة نقل الطاقة الكهربائية بالشركة العامة للكهرباء كمثال للدراسة . Abstract Through implementation of the maintenance policies, companies face challenge with respect to system maintenance cost, which is how to keep the system in good working condition at low maintenance cost? Thus the tradeoff process between cost and performance of the system plays an important role in the selection of the maintenance policies.This research is intended to achieve the optimum maintenance policies, and to achieve the leverage between system performance and life cycle maintenance cost. It focused on accomplishing the following points:Developing a mathematical model to evaluate maintenance policies through life cycle of the system.Assessing the impact of maintenance parameters on system performance measures.Using the developed model to determine the appropriate overhauling times for the industrial enterprises, actually when the equipments should be overhauled, instead the traditional way, that is performed based on fixed number of years. The model works based on criteria's are set by enterprise's decision makers, such that if the system exceeds certain number of breakdowns through its life cycle, then system must be overhauled. This thing helps the companies saving money. Using appropriate performance measures to evaluate how well the system meets its goals based on the applied maintenance policy. Practical and analytical study of power transmission station's equipments in general electrical company of Libya was presented as a case study.
