Towards a Reliable Framework of Uncertainty-Based Group Decision Support System
This study proposes a framework of Uncertainty-based Group Decision Support
System (UGDSS). It provides a platform for multiple criteria decision analysis
in six aspects including (1) decision environment, (2) decision problem, (3)
decision group, (4) decision conflict, (5) decision schemes and (6) group
negotiation. Based on multiple artificial intelligent technologies, this
framework provides reliable support for the comprehensive manipulation of
applications and advanced decision approaches through the design of an
integrated multi-agents architecture.Comment: Accepted paper in IEEE-ICDM2010; Print ISBN: 978-1-4244-9244-
Class-based Rough Approximation with Dominance Principle
Dominance-based Rough Set Approach (DRSA), as the extension of Pawlak's Rough
Set theory, is effective and fundamentally important in Multiple Criteria
Decision Analysis (MCDA). In previous DRSA models, the definitions of the upper
and lower approximations are preserving the class unions rather than the
singleton class. In this paper, we propose a new Class-based Rough
Approximation with respect to a series of previous DRSA models, including
Classical DRSA model, VC-DRSA model and VP-DRSA model. In addition, the new
class-based reducts are investigated.Comment: Submitted to IEEE-GrC201
