Definition of terms and context of the design study
The purpose of this chapter was to define basic concepts that underlie multiple criteria decision methods, decision support systems, and the context of cooperative multiple criteria group DSS in group decision-making situations.
Despite the multitude of algorithms found in multiple criteria decision methods, MCDM processes can be invariably broken into four steps: (i) identification and definition of alternatives, (ii) identification and definition of evaluation criteria, (iii) evaluation of alternatives according to criteria, and (iv) use of an algorithm to search for a solution.
Attempt to design multiple criteria DSS implies integration of MCDM methods into more elaborated dialogue interface and data base management. Furthermore, expanding MCDM to support group decision-making accentuates the differentiation between content-oriented and process-oriented approaches to decision-making. Such an extension also requires consideration of additional frameworks that help understand and resolve group decision-making such as aggregation of preferences and consensus seeking.
Before elaborating on the requirements analysis and design issues for cooperative multiple criteria group DSS, it is necessary to review important work related to collective decision-making.
