What does the Four-Library System of DSS refer to?

[JulianaRose]

dss's four-library system refers to adding a method library on the basis of the three libraries. Here are the relevant introductions: 1. DSS System: The method library of dss's four-library system mainly stores some standard algorithm programs for the model library to call. The Decision Support System (referred to as DSS) is a computer application system that assists decision-makers in making semi-structured or unstructured decisions through data, models, and knowledge in a human-computer interaction manner. 2. DSS Structure: The DSS structure is based on the traditional three-library DSS, adding a knowledge base and an inference engine, incorporating a natural language processing system (LS) into the human-computer dialogue subsystem, and inserting a problem processing system (PSS) between the four libraries to form the four-library system structure.
