Abstract

Decision support systems (DSS), defined as an interactive computer-based system to support solving decision problems, have been developed and widely applied in real-world decisions. DSS have evolved from supporting individual decisions to supporting groups and then to supporting organisation-wide decisions. In response to the new issue identified within human decision-making process, many scholars and researchers have invested a significant amount of effort to search for solutions, which resulted in the emergence of knowledge-based systems (KBS), which is also termed as expert systems in America. Since 1990s, KBS and expert systems have been playing an important role in the new generation of DSS, which has led to the development of knowledge-based decision support systems (KB-DSS).
