The use of traditional methods to analyze massive amounts of data sets is not conducive to the discovery of new knowledge patterns supports the decision-making process So the purpose of this article is designed visual analysis system that supports analysis of data sets through the use of automated analysis, which includes many of the techniques such as assembly process (clustering) and Altnsnev (classification) and the correlation base (association Rule) And the process of visual data exploration techniques Manifesting, and then the comparison with other data sets manifestation techniques and evaluation of the proposed Manifesting system.

The Research Aims: Syrian organizations keep large amounts of information and data about their personnel in their IT systems. This information, however, is often left unutilized or may be analyzed through statistical methods. In this study, DM is considered a solution for analyzing HR data and explore knowledge from data stored in some Syrian organization through two major stages: Stage A: Using results of Semi-Annual performance evaluation process to build prototype showed in (Fig. 6) to accomplish two tasks: 1. Building a models to predict appropriate job function for an employee through majority principle and using high accuracy result to increase the number of training data and make it self-learning model. 2. Choose most important attributes that used in classify methods to use it in personnel selection and recruitment. Stage B: Using data of Time & Attendance to analysis personnel activity through clustering methods and building many meaningful groups.
Educational data mining aims to study the available data in the educational field and extract the hidden knowledge from it in order to benefit from this knowledge in enhancing the education process and making successful decisions that will improve th e student’s academic performance. This study proposes the use of data mining techniques to improve student performance prediction. Three classification algorithms (Naïve Bayes,J48, Support Vector Machine) were applied to the student performance database, and then a new classifier was designed to combine the results of those individual classifiers using Voting Method. The WEKA tool was used, which supports a lot of data mining algorithms and methods. The results show that the ensemble classifier has the highest accuracy for predicting students' levels compared to other classifiers, as it has achieved a recognition accuracy of 74.8084%. The simple k-means clustering algorithm was useful in grouping similar students into separate groups, thus understanding the characteristics of each group, which helps to lead and direct each group separately.
In this article, we propose a mathematical model, fundamentally based on evidence theory in order to process and to combine the information elements coming from different sources of information in a security system. These elements could be heteroge neous (qualitative, quantitative, ordinal, binary … etc.) and imperfect (imprecise, ambiguous, probable, missing values … etc.). Along with the heterogeneity and the imperfection, we must consider the case bases that contain security cases with solutions to help us to make decisions as supplementary sources of information (this is called in machine learning field ''case-based reasoning''). Furthermore, the proposed method must consider the conflict and the contradictory resulting from the different sources of evidence. The afore-mentioned issues will be explained through an illustrative numeric example to clarify the proposed model.
The university is undoubtedly one of the basic components of modern state, but of the most important priorities, as they play an active role in the transfer of state-of-the stage of underdevelopment and dependency to the growth and development phase. Education has become a strategic resource of modern societies because it extends the community with all requirements of the specialized scientific personnel helping to increase the benefit and enhance the economic, social and cultural growth.
The decision-making process is the most important topics of operations research, which offers methods and tools to assist decision makers in reaching resolution. Research overture applied and analytic study for decision making state in production workshops whose belong estimation of optimal production size and overture mathematical model for production plan by dependence on Input – Output table for constraint production size in every workshop and coordination between internal demand, market, and production plan for solve recession problem and estimation of plan profits. Research eventuates to results overture Input – Output table model practicable in any production unit.
