This paper develops several novel kinds of power geometric operators, which are referred to as variable power geometric operators, and extends them to interval-valued hesitant fuzzy environments. A series of generalized interval-valued hesitant fuzzy power geometric (GIVHFG) operators are also proposed to aggregate the IVHFSs to model mandatory requirements. One of the important characteristics of these operators is that objective weights of input arguments are variable with the change of a non-negative parameter. By adjusting the exact value of the parameter, the influence caused by some \u201cfalse\u201d or \u201cbiased\u201d arguments can be reduced. We demonstrate some desirable and useful properties of the proposed aggregation operators and utilize them to develop techniques for multiple criteria group decision making with IVHFSs considering the heterogeneous opinions among individual decision makers. Furthermore, we propose an entropy weights-based fitting approach for objectively obtaining the appropriate value of the parameter. Numerical examples are provided to illustrate the effectiveness of the proposed techniques.<\/jats:p>","DOI":"10.1142\/s0219622016500255","type":"journal-article","created":{"date-parts":[[2016,5,13]],"date-time":"2016-05-13T07:14:27Z","timestamp":1463123667000},"page":"1055-1114","source":"Crossref","is-referenced-by-count":19,"title":["On Extending Power-Geometric Operators to Interval-Valued Hesitant Fuzzy Sets and Their Applications to Group Decision Making"],"prefix":"10.1142","volume":"15","author":[{"given":"Sheng-Hua","family":"Xiong","sequence":"first","affiliation":[{"name":"School of Transportation and Logistics, Southwest Jiaotong University, Chengdu, Sichuan 610031, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhen-Song","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Transportation and Logistics, Southwest Jiaotong University, Chengdu, Sichuan 610031, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yan-Lai","family":"Li","sequence":"additional","affiliation":[{"name":"School of Transportation and Logistics, Southwest Jiaotong University, Chengdu, Sichuan 610031, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kwai-Sang","family":"Chin","sequence":"additional","affiliation":[{"name":"Department of System Engineering and Engineering Management, City University of Hong Kong, 83 Tat Chee Avenue, Kowloon Tong, Hong Kong, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2016,9,5]]},"reference":[{"key":"S0219622016500255BIB001","doi-asserted-by":"publisher","DOI":"10.1287\/opre.2015.1350"},{"key":"S0219622016500255BIB002","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-0114(86)80034-3"},{"key":"S0219622016500255BIB003","doi-asserted-by":"publisher","DOI":"10.1016\/0165-0114(89)90205-4"},{"key":"S0219622016500255BIB004","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2013.06.013"},{"key":"S0219622016500255BIB005","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2012.04.003"},{"key":"S0219622016500255BIB006","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2010.04.064"},{"key":"S0219622016500255BIB007","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2011.01.036"},{"key":"S0219622016500255BIB008","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2011.09.099"},{"key":"S0219622016500255BIB009","doi-asserted-by":"publisher","DOI":"10.1016\/j.apm.2012.04.031"},{"key":"S0219622016500255BIB010","doi-asserted-by":"publisher","DOI":"10.1016\/j.knosys.2012.09.009"},{"key":"S0219622016500255BIB011","doi-asserted-by":"publisher","DOI":"10.1109\/TFUZZ.2013.2239650"},{"key":"S0219622016500255BIB012","volume-title":"Fuzzy Set, System: Theory and Applications","author":"Dubois D.","year":"1980"},{"key":"S0219622016500255BIB013","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2013.03.034"},{"key":"S0219622016500255BIB014","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2014.02.009"},{"key":"S0219622016500255BIB015","doi-asserted-by":"publisher","DOI":"10.1016\/j.knosys.2012.08.019"},{"key":"S0219622016500255BIB016","first-page":"113","volume":"16","author":"Gomes L.","year":"1992","journal-title":"Foundations of Computing and Decision Sciences"},{"key":"S0219622016500255BIB017","doi-asserted-by":"publisher","DOI":"10.1016\/j.cie.2009.05.007"},{"key":"S0219622016500255BIB018","doi-asserted-by":"publisher","DOI":"10.1142\/S0219622010004160"},{"key":"S0219622016500255BIB019","doi-asserted-by":"publisher","DOI":"10.1017\/CBO9781139644150"},{"key":"S0219622016500255BIB020","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2011.11.042"},{"key":"S0219622016500255BIB021","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2012.09.010"},{"key":"S0219622016500255BIB022","doi-asserted-by":"publisher","DOI":"10.1002\/int.21653"},{"key":"S0219622016500255BIB023","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-0114(98)00093-1"},{"key":"S0219622016500255BIB024","doi-asserted-by":"publisher","DOI":"10.1109\/3477.915345"},{"key":"S0219622016500255BIB025","doi-asserted-by":"publisher","DOI":"10.1109\/TFUZZ.2006.889952"},{"key":"S0219622016500255BIB026","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2010.02.095"},{"key":"S0219622016500255BIB027","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2014.02.137"},{"key":"S0219622016500255BIB028","doi-asserted-by":"publisher","DOI":"10.1142\/S0219622012500095"},{"key":"S0219622016500255BIB029","doi-asserted-by":"publisher","DOI":"10.1016\/j.knosys.2013.08.028"},{"key":"S0219622016500255BIB030","doi-asserted-by":"crossref","first-page":"65","DOI":"10.3233\/IFS-130978","volume":"27","author":"Liao H.
