THE TOOLS OF DECISION SUPPORT SYSTEMS

THE TOOLS OF DECISION SUPPORT SYSTEMS

Decision support systems tools are programs or codes which are the foundation used to create the generations and in turn specific DSS.

Decision support tools may involve the following: -

1. Material requirement planning (MRP) – MRP is a method for ordering and maintaining materials in stock. It is a systematic approach to identify cost-beneficial ways of storing materials.

2. Linear programming – Linear programming assists in solving problems which involves allocation off limited resources and evaluation of alternatives to achieve objectives.

3. Queuing theory – Queuing theory is used in planning the activities of the organization to determine economically beneficial queues e.g. production of goods.

4. Descriptive statistics- Descriptive statistics are used to estimate parameter and the dispersion of values associated with that parameter. These estimates are made for the various critical environmental factors to plan the day-to-day operations of the organizations.

5. Correlation analysis- Correlation analysis is made to calculate relationship between values for particular parameters, such parameters value describing current conditions.

6. Variance analysis- Variance analysis is used to describe variance between two or more variables.

7. Network analysis- Network analysis is a pictorial tool for identifying and sequencing tasks. Those analysis help manager in controlling tasks necessary for successful operation of organization.

8. Transportation problems- Transportation problems are used for planning and distribution of various facilities and resources.

9. Maximum flow or distance – Program flow or distance is a tool for identifying the most economically beneficial flow through, or distances between, particular objects, this facilitates in determining the most preferred flow of goods or services through an object for which the organization must conduct business.

10. Dynamic programming – Dynamic programming is a tool to enable that appropriate course of action and top-level management are being followed by managers at operational level.

11. Regression analysis- The regression analysis can be used to estimate particular values on the basis of known values for variables. It may be used to estimate the value of known variables which may influence plans for implementing the decision of top-level managers.

12. Markov processes – Markov processes are tools used to determine global associated with the occurrences of the related to changing probabilities of particular object. These global probabilities can then be used to determine more appropriate courses of action for the organization.
