Methodology

Scope: 50 U.S. schools and three journals: Management Science, Operations Research, and M&SOM.

Paper classification: A paper is classified as OM/OR using Management Science departments where OM/OR is typically published (for example, Operations Management, Healthcare, and Optimization). This is augmented by GPT-5.3 inference for papers in other departments. Using this process, 26.8% of Management Science papers (2016 onward) are classified as OM/OR. For the two core operations journals, the OM/OR shares are 99.1% for Operations Research and 100.0% for M&SOM, so the overwhelming majority is included.

School mapping: Author affiliations at publication are mapped to ranked schools only if a business school affiliation is present in the affiliation text. Postdocs and PhD students are not included in faculty counts.

Citation source: OpenAlex only (DOI-based matching; cited_by_count).

Faculty counts: Research-track Operations Management / Decision Sciences faculty only (assistant, associate, full). Excludes clinical, teaching-track, emeritus, adjunct, visiting, and practice-track roles.

Metrics:

Papers / School / Year: school-level paper credits divided by the number of years in the selected window. A paper counts once for a school, even if multiple authors from that school appear on it.
Papers / Faculty / Year: author-level paper credits divided by OM faculty count and by years in the selected window. If two authors from the same school are on a paper, that school receives two faculty-level credits.
Citations / School / Year: total citations attached to the school-level paper set, divided by years in the selected window.
Citations / Faculty / Year: the same school-level citation total divided by OM faculty count and by years in the selected window.

Rolling windows: the table and graph also allow rolling five-year windows from 2016–2020 through 2022–2026.
