| Abstract | Cooperative problem Solving is gaining popularity as a powerful strategy for overcoming the inherent bounds of intelligence present in any finite AI system. In this thesis, the potential of applying neural network techniques for cooperative problem solving has been explored. For this purpose, a framework was designed which uses Cognitive Maps for knowledge representation of cooperating agents. Using appropriate aggregation functions, CMs of related agents are pooled together to arrive at cooperative solutions. The composed CMs are then encoded into neural networks (Auto-Associators) to simulate the parallel nature of human judgmental thinking. A learning algorithm is applied upon the Auto-Associative Net which allows it to self-adjust. Solutions, initially partial, are derived from the learnt network and passed as new focuses. Global solutions are achieved through repeated pooling and derivation until all disparities are resolved. To test the devised framework, a knowledge model of a group decision support application area was also designed. The test data was extracted from an operations research consultancy project concerned with identifying a successful future for an ailing publishing company. A complete simulation of the proposed Cooperative Problem Solver was then undertaken. This package has a generic loading program capable of accepting any society of CMs. For the purposes of this research, the designed test data was used and the proposed framework was tested for a variety of results. Conclusions and recommendations have been put forward on the basis of the results obtained. |
