The Service Enterprise Systems (SES) program, sponsored by the National Science Foundation (NSF), supports research on decision-making related to the design, planning, and operation of commercial, nonprofit, and institutional service enterprises. The goal is to improve the overall effectiveness and cost reduction of these enterprises. Research proposals should be grounded in relevant applications and require the development of novel analytical and computational methodologies. Key research areas of interest include healthcare operations, financial engineering, transportation logistics, and national security. Proposals will be evaluated based on their potential to advance scientific knowledge, develop innovative technologies, and address national challenges. The SES program offers grant funding, with typical award amounts ranging from $250,000 to $650,000 for project periods of 3-5 years. The program is open to a wide range of applicant types, including academic institutions, research organizations, and other eligible entities across the United States. The place of performance is not specified, but the research is expected to be conducted at the applicant's facilities.
