Knowledge is crucial for making good decisions in society. Different types of knowledge like data, information, and knowledge itself are transformed to create new knowledge. Models like SECI and BCI help in this transformation process. Decision Support Systems (DSS), Geographic Information Systems (GIS), and Operations Research/Management Science (OR/MS) play a key role in creating new knowledge by supporting decision-making. DSS help decision makers, GIS provide important business insights, and OR/MS models improve decision precision. These tools help in creating both explicit and tacit knowledge.
