يتضمن هذا البحث تقييم عمل صيانة الآليات من خلال مؤشرات الأداء الرئيسة الخاصة بها، و المعتمدة من قبل الشركات الصناعية و الخدمية و نذكر منها الموثوقية، و الجاهزية، متوسط الزمن بين الأعطال، متوسط زمن اصلاح الأعطال، متوسط زمن الصيانة الدورية لمعداتها الانتاجية و الخدمية. بعد معالجة البيانات الخاصة بالأعطال الطارئة و الصيانة الدورية التي تمت على الآليات تم استخلاص قيم المؤشرات الخاصة بالصيانة و قياس أداءها و ترابطها لمعرفة مدى مطابقتها مع المؤشرات العالمية الموجودة. يهدف البحث إلى تقييم الوضع الراهن من خلال استخدام نمط الأساليب الكمية المستخدمة في الوصول لقيم مؤشرات الأداء السابقة الذكر و ترابطها لاستخدامها في دعم قرارات الصيانة في محطة الحاويات لاحقاً. تم التوصل إلى ارتباط عكسي قوي بين زمن الصيانة الدورية TPM و زمن إصلاح الأعطال TBD ، وصلت قيمته rERS= -0.99، و بالتالي يجب التركيز على زيادة عمليات الصيانة الدورية للتقليل من زمن إصلاح الأعطال، و إجراء استبدال للأجزاء التي تسبب المشاكل المتكررة حيث تسببت بأعطال دورية مكثفة مما يقلل من زمن الصيانة الدورية. كما تمكنا من تصنيف جودة الصيانة و الآلات من خلال مؤشرات الجاهزية و الموثوقية و متوسط الزمن بين الأعطال.
This research includes evaluating the work of maintenance of themachines through their own key performance indicators (KPI), and approved byindustrial and service companies, We mention reliability, readiness ,average time between failures, average Repair time ,average time of periodic maintenance of their production and serviceequipment. After the data processing of emergency failures and periodic maintenanceof machines , we extracted values for maintenance performanceindicators, we measured their performance and correlation to evaluateits compatibility with global indicators. The research aim to assess the current situation through the use ofquantitative methods pattern which is used to access the values of theprevious mentioned performance indicators and their interdependence tobe used in support of maintenance decisionsin the container terminal later. We noticed a strong inverse association between periodic maintenance TPMtime and breakdown TBD, and reached a value rERS = -0.99, and thereforewe must focus on increasing periodic maintenance to reduce breakdowntime, and replace parts that cause recurringproblems which caused about intensive breakdowns, thus reducing periodicmaintenance time. Also we were able to classify the quality of maintenance and machinesthrough the readiness and reliability indicators and the mean timebetween failures.

School buildings in Syria suffer of the high cost of maintenance works. In addition,
there is no fear methodology to organize the maintenance process and evaluate the
performance of these buildings.
This research aims to develop a system for evalu
ating the performance of school
buildings in the city of Tartous, in order to be used in the maintenance policy for these
buildings and other buildings in other regions.
The evaluating process is executed by calculating a performance indicator, which
defines the state of the building depending on three sub-indicators: functional, technical
and healthiness indicator.
Maintenance manual and evaluating lists were developed to evaluate the components
of school building. In addition, many questionnaires were set to determine the relative
importance for each component of school building.
The improved model was used to calculate the performance indicators for several
schools. As a result, most of these schools were in a moderate situation. Also, the results
clarify that some components have law state comparing to other ones and we should focus
on them in organized maintenance processes.
Economic growth and high competition have put a strong pressure on construction companies to improve their productivity and performance. Many studies on performance measurement have been carried out at the project level. Recently, the demand for perf
ormance evaluation at the company level has increased. This paper aims to identify a set of Key Performance Indicators (KPIs). A List of 20 potential performance indicators has been identified according to Balance Score Card (BSC) through a quantitative and qualitative analysis. We have obtained the required information about the relative importance of the indicators through interviews with six experts in the construction industry to determine the size of the relative importance of each indicator, on the grounds that a large number of performance indicators are difficult to measure and control. We have adopted the Analytic Hierarchy Process (AHP) to identify fewer and more effective performance indicators. And we have used Expert Choice software to analyze expert answers. As a result, we have obtained 9 important indicators which can be directly used as indicators to measure and identify performance projects or as indicators within an integrated system, for performance measurement and tracking helps in improving the performance of construction projects in Syria.
A comprehensive literature review was carried out in order to
identify potential factors that have an influence on project
performance. Based on this review, a formal questionnaire survey
was developed and sent to a carefully selected focus group
of
construction experts from within the Syrian construction industry.
In this research, we developed an algorithm to measure
the quality of processed digital video, with no
information about the video before processing, to know
how much the video was distorted as a result of

This study aims to evaluate and compare the financial performance of the Jordanian
Islamic and conventional banks using the five financial indicators of the "CAMEL"
method represented by: Capital Adequacy index, Asset Quality index, Management
Qua
lity index, Profitability index, and the Liquidity index. This comparison will detect
which of the two banks Islamic or Conventional achieves a better performance than the
other. In order to study the reflection of financial performance on customers at the level of
public trust, and to achieve these purposes, we select a total of thirteen Jordanian
Conventional banks and two Islamic banks as a sample for this study during the period of
(2006-2012). We employ a test “t-test” to study the significance of the differences between
the averages of financial ratios and the use of multiple linear regression analysis to show
the impact of financial performance indicators individually and collectively on the level of
public trust. The result of this study clearly shows that Conventional banking achieves a
better financial performance than Islamic banking, although the level of public trust of
customers in Islamic banking stems mainly from its achieved financial performance,
contrary to what has been obtained during this study for Conventional banking.
