In this study, we define the concept of possibility SNS including two types of information such as the neutrosophic performance provided from the evaluation objects and its possibility degree using a value ranging from zero to one. Then by extending the existing neutrosophic information, aggregation models for SNSs that cannot be used effectively to fusion the two different information described above, we propose two novel neutrosophic aggregation operators considering possibility, which are named as a possibility-induced simplified neutrosophic weighted arithmetic averaging operator and possibility-induced simplified neutrosophic weighted geometric averaging operator, and discuss their properties. Moreover, we develop a useful method based on the proposed aggregation operators for solving a multi-criteria group decision-making problem with the possibility simplified neutrosophic information, in which the weights of decision-makers and decision criteria are calculated based on entropy measure. Finally, a practical example is utilised to show the practicality and effectiveness of the proposed method. © 2016 Informa UK Limited, trading as Taylor & Francis Group.eninfo:eu-repo/semantics/closedAccessmulti-criteria group decision-makingNeutrosophic setspossibility simplified neutrosophic setssimplified neutrosophic setsMathematical operatorsAggregation operatorArithmetic averagingAveraging operatorsConcept of possibilityDecision criterionsDecision making processMulti criteria group decision makingNeutrosophic setsDecision makingmulti-criteria group decision-makingNeutrosophic setspossibility simplified neutrosophic setssimplified neutrosophic setsMathematical operatorsAggregation operatorArithmetic averagingAveraging operatorsConcept of possibilityDecision criterionsDecision making processMulti criteria group decision makingNeutrosophic setsDecision makingArticle29476978510.1080/0952813X.2016.12592662-s2.0-84999673388Q3WOS:000403013800007Q3
