The DSS Architecture Based on Non-Mathematical Problems Specification and Model/Solver Independence

  • Tsuyoshi Mukohara

Part of the International Series in Operations Research & Management Science book series (ISOR, volume 43)


The proposed DSS architecture includes (1) specifying decision problems with an extended entity-relationship model ‘GERM’, (2) distinguishing a user-defined model from a standard model, (3) bridging a problem specification and its user-defined model through ‘unification condition’, and (4) bridging a user-defined model and a standard model through ‘connection information’. A prototypal DSS with the proposed architecture helps a decision-maker having insufficient mathematical knowledge to communicate with OR/MS experts and to select and invoke an adequate solver for a decision problem.
