The INFORMS Analytics Society connects professionals and researchers in analytics, operations research, optimization, data science, machine learning (ML), and artificial intelligence (AI) to advance data and decision intelligence across industries. Members access exclusive networking, cutting-edge research, career development, and industry insights. Join us to stay ahead in the evolving world of analytics and operations research.

The Applied Probability Society (APS) of INFORMS advances the application of probability theory to understand and improve operations in systems affected by uncertainty and randomness. Domains of applications include manufacturing, communication networks, service platforms and market design, revenue management, healthcare, finance and insurance, energy, logistics and transportation, social networks, as well as emerging data science applications and integrations with operations. APS fosters the development of rigorous analytical, algorithmic, and statistical methodologies broadly rooted in probability and stochastics to devise cutting-edge techniques that drive innovations in decision-making under uncertainty, bringing together a diverse community from fields such as business, engineering, statistics, mathematics, economics, and computer science.

The INFORMS Computing Society (ICS) addresses the interface of OR and computing. Since their earliest days, OR and computing have been tightly linked. The practice of OR depends heavily on the availability of software and systems capable of solving industrial-scale problems: computing is the heart of OR in application.

ICS is INFORMS' leading edge for computation and technology. Major ICS interests are algorithms and software for modeling, optimization, and simulation.ICS is also interested in the leading edge of computing and how it affects OR (e.g. XML modeling standards, OR services offered over the web, open source software, constraint programming, massively parallel computing, high performance computing).

The mission of the Data Mining Society is to promote and disseminate research and applications among professionals interested in theory, methodologies, and applications in data mining and knowledge discovery.

The Decision Analysis Society advances decision-making through practical, science-based guidance and groundbreaking research. Rooted in Nobel Prize-winning contributions like subjective expected utility, Bayesian inference, and prospect theory, our work integrates psychology, game theory, risk analysis, and data analytics. By bridging human and machine learning, we pioneer innovative techniques to solve complex societal challenges.

The Health Applications Society focuses on the topics of health applications, with the aim of identifying current and potential problems and contributions to their solutions; to lead in the development, dissemination, and implementation of knowledge and advancing the basic and applied research technologies on health applications.

The INFORMS Information Systems Society seeks to foster, promote, and disseminate research on the use and impact of information technology in organizations. It provides a forum for researchers and practitioners in information systems to interact and further their interests in the area. One of the goals of the society is to encourage interdisciplinary research by leveraging connections between other societies and colleges within the INFORMS environment.

Promoting the enhancement and dissemination of knowledge, as well as the effectiveness and efficiency of industrial practice, related to the operations of manufacturing and service enterprises.

INFORMS Society for Marketing Science (ISMS) is a premier global organization dedicated to advancing the theory and practice of quantitative marketing research, analytics, and data-driven decision-making. ISMS connects marketing academics, marketing industry professionals, and marketing PhD students through cutting-edge research, the Marketing Science journal, and prestigious conferences including the ISMS Marketing Science Conference, ISMS Early-Career Scholars Camp, and ISMS Doctoral Consortium. Members gain access to networking, mentorship, and job resources, and support prestigious awards such as the John D.C. Little Best Paper Award. ISMS drives innovation in marketing applications of AI, econometrics, machine learning, and consumer behavior modeling.

The Military and Security Society (MAS) is an application-focused, technical society dedicated to advancing the science and practice of decision-making for global security.

The Optimization Society aims to advance the field of operations research and management sciences (OR/MS) by promoting the development and application of optimization methods and software tools for solving complex problems. Additionally, it seeks to foster the exchange of information and ideas among practitioners and scholars working in the area of optimization, encouraging collaboration and innovation within the community.

Organized and operated exclusively for educational and scientific purposes:

a. to encourage the development and dissemination of knowledge in the area of simulation; and
b. to promote communication and interaction among individuals and organizations who share an interest in simulation.

The TSL Society provides INFORMS members with a sustained, specialized focus on all topics of transportation science and logistics. It supports education, research, and professional development while serving as the editorial home of Transportation Science. The Society includes special interest groups in air transportation, freight logistics, urban planning, facility logistics, and intelligent transportation systems.
