Decision Support System couple the intellectual resource of individuals with the capabilities of the computer to improve the quality of decision. It's a computer based support system for management decision makers who deal with semi-structured problem. An integrated decision support system for use in an machine mollen product has been developed. It incorporates a linear Programming model that represents the contribution optimal and optimizes the production water pump and mollen machine. An optimization model is performed using a management scient model called linear programming approach in older to determine media selection. To use this model, the DSS needs ti interface with another software. Mathematical Programming is a technique used in mathematical models, particularly optimization models, to assist in decision making. The Simplex Method is "a systematic procedure for generating and testing candidate vertex solutions to a linear program." (Gill, Murray, and Wright, p. -137) It begins at an arbitrary corner of the solution set. At each iteration, the Simplex Method selects the variable that will produce the largest change towards the minimum (or maximum) solution. The  development of computer programs to be used as Decision Support Systems involves several tasks such as mathematical modeling, technical and data collection and development of a user friendly interface.

A university as an educative institution needs an assessment for the programs it has. In order to conduct such assessment , some components need to be assessed based on the internal and external factors. It is necessary to establish a decision support system toward the performance of the department. It can help the decision maker to know the condition occurred in this department. 'l he assessment of the study program's performance for evaluating can be done by underlining the components that will be assessed by making the model. The model which is prepared by applying some rules, stated in accreditation board, will be used as a reference in performance assessment for  Diploma III program. By applying a model toward the assessment criteria from the related department, it will help us to get the result. The achieved result is in form of the total score from the assessment, the score is devided into 5 class excellent, very good, good, sufficient and poor. Consequently, the report of resulting assessment can be to determine some steps to improve or maintain the recent achievement. By applying the decision support system of the department’s performance , it allow a decision maker to be able to monitor the department or the study program.

Object-Oriented Programming is innovation in development for software the last decade, moreover to appear visual programming language models. OOP concept needed for implementation components used in application preparation and preparation new component, so that to appear visual programming language models, preparation new component in veil VB programming is news interesting, except for to fill requisites unique new component, so using plentiful OOP concept.

This article discuss research progress and future opportunities for modeling consumer choice on the Internet using clickstream data and also to compare the nature of Internet choice (as captured by clickstream data) with supermarket choice (as captured by UPC scanner panel data). Though the application of choice models to clickstream data is relatively new, and review existing early work and provide a two-by-two categorization of the applications studied to date (delineating search versus purchase on the one hand and within-site versus across-site choices on the other). The article discusses additional opportunities afforded by clickstream information, including personalization, data mining, automation, and customer valuation and also offers directions for further research in these areas. Notwithstanding the numerous challenges associated with clickstream data research.

When creating databases for GIS-applications often existing maps are scanned and vectorised for used. However, vectorisation becomes obsolete when GIS-objects can be referred to both in theme and geometry in a raster environment. This article shows to use model spatial data raster and vector for GIS - applications in both the graphical and image structure. Geographical data must first be converted into a computer- readable format before it can be used in a GIS. Spatial data are "elements that can be stored in map form." These elements correspond to a uniquely defined location on the Earth's surface. Spatial data have also been describe as “any data concerning phenomenon a really distributed” in two or more dimensions. (Peuquet and Marble, I990.) Data model is the rules to convert real geographical variation into discrete objects. There are two main GIS data models - vector and raster. Each of the two data models has specific types of data, analysis and displays that can handle better than the other system. The vector model represents geographical reality as a series of discrete objects or features, classified as points, line's or areas (polygons). The geographical co-ordinates describing the locations of these features are stored in the computer database which lies at the heart of the GIS. In the raster model a regular grid of cells, or pixels, is used to encode the features found on the earth's surface. Each pixel has a number associated with it representing; the value of a geographical phenomenon, such as terrain elevation, soil type or biomass. Layers of raster grids covering the same region can be built up to represent further variables.

This paper presents n conceptual model of Internet-based business-consumer relationship marketing with a focus on the context, content, and the process of relationship development from the consumer's perspective. The model con be divided into two broad groups. The first group is a set of contextual factors (environment, parties to the relationship, consumption task) that influence relationship development. The second group is the content and process of relationship development that can be viewed via three interrelated conceptual phases: consumer motives to seek interaction, exploration and interaction, and relationship bonding. With the rapid growth of E-commerce and on-line consumer shopping trends, the importance of building and maintaining customer loyalty in electronic marketplaces has come into sharper focus in marketing theory and practice. This paper also to present a conceptual framework of "e-loyalty" and its underlying drives.

Resiko yang dihadapi oleh kebanyakan pengguna atau pemakai komputer sering kurang mendapatkan perhatian yang utama dalarn perlakuan antisipasi yang mungkin akan terjadi pada komputernya. Padahal perlakuan preventif atau pencegahan ini sangat penting sekali. Para pemakai komputer baru sadar dan baru melakukan perlakuan pengamanan secara represif setelah resiko teriadi dan menimbulkan akibatkan yang sangat merugikan baik pada dirinya secara langsung maupun secara tidak langsung. Para pengguna kurang begitu menyadari dan bahkan kurang peduli terhadap perlakuan system sekuritas terhadap komputernya, hal ini diakibatkan karena pengetahuan yang terbatas dari kebanyakan pemakai komputer. Untuk itu dalam penelitian ini perlu mengambil topik tentang aspek-aspek sekuritas pada system komputer. Hasil penelitian ini dapat melakukan identifikasi masalah sekuritas komputer, yaitu menentukan bagaimana komputer dapat rusak ditinjau dari sisi perangkat keras (hardware), perangkat lunak (software), dan pengaruhnya terhadap pemakai (user), dan bagaimana langkah pencegahan sebelum terjadinya kerusakan, dan menentukan langkah penanggulangannya setelah terjadi kerusakan. Bentuk pengamanan tersebut dapat dilakukan dengan menentukan model tingkat pengamanan seperti melakukan kewaspadaan terhadap pemakai, pengamanan fisik baik fisik komputer maupun lingkungan yang terlibat. Setelah melakukan tindakan pengamanan fisik maka selanjutnya melakukan tindakaan pengamanan fungsi komputer. Ancaman yang sering dirasakan oleh pengguna komputer yang berhubungan langsung dengan keamanan data, aplikasi, dan system operasi adalah Virus komputer. Saat ini untuk proteksi data dari bentuk manipulasi data yang sedang berkembang adalah dengan cara metode enkripsi. Metode ini akan melakukan enkrip atau membual kode sandi tertentu dengan cara menyamarkan data.

The passage analize about the model of DSS. Models begins step from DSS concept. After that, we must choose modeling approach, beside decision making processes. We have many types of model DSS, especially in statistical, financial and optimization. Finally, we get benefit of models.

Decision support systems based on fuzzy logic may be used to solve problems to find optimum solution on  fuzziness environmental. The differences with old decision support system is we can find optimum solution that more realities, because in fuzzy logic not use absolute  truthful right or false. Goal of this article is how to construct model base on decision support system based on  fuzzy logic.
