The prototype system incorporates reference and user databases. In this chapter, we examine a major function in class of decision support systems (dss): The use of decision support systems usually increases the manager’s ability to make correct and balanced decisions.
Figure 1 Decision support system structure.
The model directory for this specific application consists of the following:
Dss software packages are called dss generators.
According to turban, the dss has four components and the structure including data management, model management, knowledge management, and interface management. Model based management system is a set of computer programs embedded within a dss generator that allows users to create, edit, update, and / or delete a model. Models are an integral part of decision making and use for many tasks, such as designing a manufacturing facility, analyzing the financial health of an organization, forecasting demand for a product and. A manager can apply his knowledge to the system generated information and get a more clear view of the problem.
Having summarized the most important functions of a dss, it should be remembered that a dss is only as good as the individual components that it consist of:
Dbms first component of dss. They contain models of databases, model, and creation, interrogation, and maintenance of the dss database, a model base management module provides the ability to create, maintain, and manipulate the mathematical models in the models base using capabilities provided by modeling packages. A model is an abstract representation of reality. Gra model in which the evaluation was done based on quantitative criteria.
Tps captures all the data and arrange it in the database continuously updated.
Up to 10% cash back the developed model base management system has the facilities such as model base, model directory, model execution, integration of models and command processor. Dss is built on top of a transaction system, a database and a data model, all of which provides the dss with data and information that is processed and presented to the user in a simplified form. A prototype decision support system to support model management involving econometric modeling in the planning process is briefly described. In particular, the chapter focuses on.
Kb executive information system (eis) high levels of filtered information.
Decision support system (dss) management information system (mis) transaction processing system (tps) robust transaction processing system which the bedrock dss. Broadly speaking, a decision support system (dss) is an analytics software program used to gather and analyze data to inform decision making. The data that might be gathered and presented by the dss are evaluating the company’s assets and comparing information from different figures.
