Methodological aspects of creating a DSS. Possible outcomes of DSS operation

Lecture



These can be:

  • • reprocessed source information;
  • • alternative managerial or economic decisions;
  • • managerial or economic decisions proposed by the system as final.

Depending on the specifics of the situation under study, the DSS being created may be aimed at solving the following tasks:

  • • only reprocessing the source information for the purpose of presenting it in a form convenient for the DM in making any managerial or economic decisions;
  • • preliminary processing of information for the purpose of using the results obtained to form alternative and (or) final managerial or economic decisions;
  • • forming alternative managerial or economic decisions;
  • • forming decisions proposed by the system as final;
  • • forming alternative decisions and selecting from among them those that are proposed by the system as final.

The degree to which a decision support system covers methodological information

.

Depending on the option for how much methodological information a decision support system covers — information used for solving the specific tasks assigned to the DSS — a distinction is made between DSS considered in the narrow and in the broad sense.

Most often the term «decision support system» is used in the narrow sense, when a DSS is understood as a software-and-hardware complex that enables the decision maker, through the capabilities of modern electronic computers for collecting, storing and processing information, on the basis of specific models, algorithms and rules for constructing development scenarios, as well as through the use of various tools, to make well-founded decisions in complex situations. Nevertheless, the need to provide the DM with additional information — primarily methodological information on the specifics of implementing the management processes themselves and on the procedure for developing and making economic decisions, on economic-mathematical methods and tools for decision-making — leads to considering the DSS in the broad sense, when the system also includes this information.

In this case, a decision support system is understood as an information-analytical complex used to obtain:

  • • informational and methodological support for the preparation of a managerial or economic decision;
  • • information on the economic-mathematical methods and tools used for processing the source and operational information analyzed in the course of preparing the decision;
  • • the results of reprocessing this information in a form convenient for preparing a decision;
  • • alternative or final managerial decisions.
