Decision Support Systems

The activity of any manager constantly calls for decision-making.
‍
During complex decision-making, multitudes (decades or hundreds) of interconnected factors often have to be taken into consideration. To ensure a high professional level of decision-making it is necessary to integrate the knowledge of many specialists (experts). At the same time, an individual is unable to operate with more than 7-9 objects simultaneously. To overcome this constraint decision support systems are used.

Three classes of DSS can be marked out in accordance with their functional capacities:

01

First DSS class

These are individual usage systems, where knowledge bases are filled by the immediate user. Multi-criteria alternative estimation is used in such systems. They are primarily intended for usage by medium-rank public servants.

02

Second DSS class

These are systems capable of adapting to the user’s experience. They are intended for decision-making support in situations that are often repeated (such as crediting subject choice, job contractor selection, appointing a candidate for a vacant post, etc). Such systems also use the multi-criteria estimation of alternatives and provide decision-making support in the current situation based on results of practical usage of previously-obtained results.

03

Third DSS class

These systems can be used even in cases when DSS of the first and second classes are impossible to apply due to a lack of common criteria allowing for the estimation of every alternative. They provide maximal functionality, intended for application in highest-level governmental bodies (Administration of the President, Supreme Council, Cabinet of Ministers, ministries, oblast state administrations) and large busyness structures.
