This study applies Structural Variation Analysis (SVA) to assess the interdisciplinary impact of a highly cited paper on the Cross-Entropy Method in Operations Research. Using co-citation network analysis, the authors examine structural shifts through key metrics, including modularity change (\u2206M = 52.57), cluster linkage (CL = 135.2), centrality divergence (CKL = 0.47), and entropy (E = 0.98). The findings reveal that this methodological paper plays a pivotal role in bridging previously unconnected research domains. Beyond accumulating citations, the Cross-Entropy Method has fundamentally altered research connectivity. SVA offers an early indicator of transformative research before conventional citation metrics can capture their full impact.<\/p>","DOI":"10.4018\/ijssmet.381314","type":"journal-article","created":{"date-parts":[[2025,6,20]],"date-time":"2025-06-20T17:17:12Z","timestamp":1750439832000},"page":"1-16","source":"Crossref","is-referenced-by-count":0,"title":["Using Structural Variation Analysis to Measure Interdisciplinary Knowledge Integration in Operations Research"],"prefix":"10.4018","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6309-5452","authenticated-orcid":true,"given":"Khaled","family":"Mili","sequence":"first","affiliation":[{"name":"Department of Quantitative Methods, College of Business Administration, King Faisal University, Saudi Arabia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6560-5153","authenticated-orcid":true,"given":"Majdi","family":"Argoubi","sequence":"additional","affiliation":[{"name":"University of Sousse, Tunisia"}]}],"member":"2432","reference":[{"issue":"1","key":"IJSSMET.381314-0","first-page":"20","article-title":"Complex inventory management: Challenges and computational models.","volume":"15","author":"K.Al Khatib","year":"2024","journal-title":"International Journal of Service Science, Management, Engineering, and Technology"},{"issue":"3","key":"IJSSMET.381314-1","first-page":"88","article-title":"The role of agile supply chain management in improving organizational performance: A case study approach.","volume":"12","author":"H.Alzoubi","year":"2021","journal-title":"International Journal of Service Science, Management, Engineering, and Technology"},{"key":"IJSSMET.381314-2","doi-asserted-by":"publisher","DOI":"10.1287\/mnsc.41.12.1946"},{"key":"IJSSMET.381314-3","doi-asserted-by":"publisher","DOI":"10.1080\/15326349508807330"},{"key":"IJSSMET.381314-4","doi-asserted-by":"publisher","DOI":"10.1088\/1742-5468\/2008\/10\/P10008"},{"key":"IJSSMET.381314-5","doi-asserted-by":"publisher","DOI":"10.1086\/421787"},{"key":"IJSSMET.381314-6","doi-asserted-by":"publisher","DOI":"10.1002\/asi.20317"},{"key":"IJSSMET.381314-7","doi-asserted-by":"publisher","DOI":"10.1002\/asi.21694"},{"key":"IJSSMET.381314-8","doi-asserted-by":"publisher","DOI":"10.1016\/j.joi.2009.03.004"},{"key":"IJSSMET.381314-9","doi-asserted-by":"publisher","DOI":"10.1517\/14712598.2012.674507"},{"key":"IJSSMET.381314-10","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0223994"},{"key":"IJSSMET.381314-11","doi-asserted-by":"publisher","DOI":"10.1287\/opre.41.4.625"},{"key":"IJSSMET.381314-12","doi-asserted-by":"publisher","DOI":"10.1007\/s10479-005-5724-z"},{"key":"IJSSMET.381314-13","doi-asserted-by":"publisher","DOI":"10.1177\/0003122415601618"},{"issue":"4","key":"IJSSMET.381314-14","first-page":"55","article-title":"The effects of marketing mix on brand equity: Empirical evidence from fast food restaurants.","volume":"12","author":"J.
