Though the main objective of this approach is to identify the efficient category value for nonhierarchical categorical factors, it can also be employed to identify the efficient category value for hierarchical categorical factors without any large adjustment. This new approach is applied to an empirical data from an Agricultural Resource Management Survey for soybean production in Pennsylvania. The result of the empirical application illustrates how our approach leads us to the efficient category value of categorical factors by using both radial measure and nonradial measure. Moreover, it shows us the existence of substantial heterogeneity in the use of categorical factors and the opportunity of improvement in DMUs' selection of category value for categorical factors.<\/jats:p>","DOI":"10.1142\/s0217595913500127","type":"journal-article","created":{"date-parts":[[2013,7,3]],"date-time":"2013-07-03T09:18:10Z","timestamp":1372843090000},"page":"1350012","source":"Crossref","is-referenced-by-count":0,"title":["AN IDENTIFICATION APPROACH OF TECHNICALLY EFFICIENT CATEGORY FOR CONTROLLABLE, CATEGORICAL FACTORS IN PRODUCTION AND AN APPLICATION TO A PRODUCTION PROCESS"],"prefix":"10.1142","volume":"30","author":[{"given":"SEUNG-MIN","family":"SONG","sequence":"first","affiliation":[{"name":"Department of Child and Family Welfare, University of Suwon, San 45, Wau-ri, Bongdam-eup, Hwasung, Kyunggi, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"TAEHO","family":"KIM","sequence":"additional","affiliation":[{"name":"Department of Business Administration, Incheon National University, 119 Academy-ro, Yeonsoo-gu, Incheon Metropolitan City, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JAE-GON","family":"KIM","sequence":"additional","affiliation":[{"name":"Department of Industrial and Management Engineering, Incheon National University, 119 Academy-ro, Yeonsoo-gu, Incheon Metropolitan City, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JANGHA","family":"KANG","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering, Chosun University, 375 Seosuk-dong, Dong-gu, Gwang-ju 501-759, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2013,10,2]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1287\/opre.34.4.513"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1287\/mnsc.32.12.1613"},{"key":"rf3","volume-title":"Durability, Separability, and Functional Structure: Theory and Economic Applications","author":"Blackorby C.","year":"1978"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.2307\/1243942"},{"key":"rf5","volume-title":"Data Envelopment Analysis: Theory, Methodology, and Application","author":"Charnes A.","year":"1993"},{"key":"rf6","volume-title":"Handbook on Data Envelopment Analysis","author":"Cook W.
