Rough集理论[1-3]自1982年由波兰数学家Pawlak Z教授提出以来，经过20多年的研究和发展，在系统理论、计算机模型的建立和应用系统的研制开发上，已经取得了许多成果，也建立了一套完整的Rough集理论体系，特别是由于上世纪80年代末和90年代初在知识发现等领域得到成功的应用而受到国际上广泛关注。

This dissertation proposes group reasoning and group AHP-based GDSS structure and its decision steps to solve the problems existing in research of theory and application of GDSS. Besides, the dissertation also studies the method of group reasoning on rough-set and qualitative reasoning method basis in GDSS. It also studies on constructing method of hierarchy structure of group AHP in GDSS and combinative method of judgment matrixes. Moreover, it studies on method regarding construction of judgment matrixes on rough set based and optimization theory of convex combination parameters of judgment matrixes as well. Finally, it develops an AHP based GDSS to demonstrate the efficiency of these methods.(1) This dissertation also summarizes the developing trend of GDSS and analyses problems as regards the research of GDSS.
