Decision help system

A decision help system DSS is an information system that supports house or organizational decision-making activities. DSSs serve a management, operations as well as planning levels of an agency usually mid and higher supervision and help people have decisions about problems that may be rapidly changing and not easily intended in advance—i.e. unstructured and semi-structured decision problems. Decision support systems can be either fully computerized or human-powered, or the combination of both.

While academics pull in perceived DSS as a tool to support decision making processes, DSS users see DSS as a tool to facilitate organizational processes. Some authors pretend extended the definition of DSS to include any system that might support decision making and some DSS put a decision-making software component; Sprague 1980 defines a properly termed DSS as follows:

DSSs increase knowledge-based systems. A properly designed DSS is an interactive software-based system refers to help decision makers compile useful information from a combination of raw data, documents, and personal knowledge, or house models to identify and solve problems and make decisions.

Typical information that a decision support applications mightand offered includes:

Classification

There are several ways to classify DSS applications. not every DSS fits neatly into one of the categories, but may be a mix of two or more architectures.

Holsapple and Whinston categorize DSS into the following six frameworks: text-oriented DSS, database-oriented DSS, spreadsheet-oriented DSS, solver-oriented DSS, rule-oriented DSS, and compound DSS. A compound DSS is the most popular line for a DSS; this is the a hybrid system that includes two or more of the five basic structures.

The support assumption by DSS can be separated into three distinct, interrelated categories: Personal Support, Group Support, and Organizational Support.

DSS components may be classified as:

DSSs which perform selected cognitive decision-making functions and are based on artificial intelligence or intelligent agents technologies are called intelligent decision support systems IDSS

The nascent field of decision engineering treats the decision itself as an engineered object, and applies engineering principles such as design and quality assurance to an explicit explanation of the elements that equal a decision.
