Systems-analysis. info is a reference and information website focused on systems analysis and related disciplines. It presents systems analysis as a scientific method for solving complex problems and connects the subject with operations research, mathematical modeling, decision theory, machine learning, artificial intelligence, and large language models.

Visitors can explore main sections of the site and browse a catalog of systems analysis materials. The website also provides access to two knowledge resources: the international, multilingual Systems Analysis Wiki and an English-language Systems Analysis Wiki. Language options listed on the site include Spanish, French, Japanese, and Russian, alongside English.

Together, these resources offer an organized starting point for readers seeking information about analytical methods, optimization, and computational approaches to complex problems. The site’s emphasis is on reference materials and knowledge sharing rather than on a clearly specified commercial product or service. Its subject range brings established techniques, such as operations research and decision theory, together with newer fields including machine learning and large language models
