DECISION SUPPORT SYSTEM: 

DECISION SUPPORT SYSTEM PRESENTED BY, GEETA BHATIA

Decision Support System: 

Decision Support System Interactive computer-based systems that help people use computer communications, data, documents, knowledge and models to solve problems and make decisions Companies use DSS to support the decision making of customers and suppliers.

Type of decisions: 

Type of decisions Programmed decisions repetitive and routine have a definite procedure Non-programmed decisions Novel and unstructured No cut-and-dried method for handling problem.

Problem solving phases: 

Problem solving phases Intelligence Searching environment for conditions calling for a solution Design Inventing, developing, and analyzing possible courses of action Choice Selecting a course of action from those available Review Assessing past choices

Slide 5: 

DSS include a wide variety of analytical information systems. DSS provide managers more control of their data, access to analytical tools. Capabilities for consulting and interacting with a distributed group of staff. Characteristics of DSS

Components of DSS: 

Components of DSS Database Management System. DBMS manipulates, updates, maintains and disseminates data. -internal data generated by TPS -external data from newspapers, census data, tax codes, census figures, competitors -online data services -databases (finance, marketing, HR and others)

Components of DSS Model Management systems – Stores and accesses models that managers use to make decisions e.g. manufacturing facility,analysing financial status, forecasting demand for product or service .

Slide 8: 

Retrieve information elements Analyze entire files Prepare reports from multiple files Estimate decision consequences Propose decisions Degree of problem solving support Degree of complexity of the problem-solving system Little Much DSS Types Make decisions 13- 8

Three DSS Objectives: 

Three DSS Objectives 1.Assist in solving semi structured problems. 2.Support , not replace, the manager. 3.Contribute to decision effectiveness, rather than efficiency.

Functions of a DSS: 

Functions of a DSS Goal seeking –determining input values to achieve goals Risk analysis-Assess risks. Decisions can be low-risk, medium-risk and high-risk. Graphical analysis-Visualize impacts of action, forecast activities, detect trends - e.g. line or bar charts, grouped line or bar charts
