Hamy mean (HM) operators play a vital role to accumulate the information. HM operators give us a more general and stretchy approach to develop the connections between the arguments. Spherical fuzzy sets (SpFSs), the further extension of picture fuzzy sets (PcFSs) that handle the data in which square sum of membership degree (MD), non-membership degree (NMD) and neutral degree (ND) always lie between closed interval [0, 1]. In the present article, we modify the HM operators like spherical fuzzy HM (SpFHM) operator and weighted spherical fuzzy HM (WSpFHM) operator to accumulate the spherical fuzzy (SpF) information. Moreover, various properties and some particular cases of SpFHM and the WSpFHM operators are discussed in details. Also, to compare the results obtained from the HM operators a score function is developed. Based on WSpFHM operator and score function, a model for multiple criteria decision-making (MCDM) is established to resolve the MCDM problem. To check the significance and robustness of the result, a comparative analysis and sensitivity analysis is also performed.<\/jats:p>","DOI":"10.3233\/jifs-201708","type":"journal-article","created":{"date-parts":[[2021,7,13]],"date-time":"2021-07-13T14:27:32Z","timestamp":1626186452000},"page":"273-298","source":"Crossref","is-referenced-by-count":7,"title":["Multiple criteria decision making based on Hamy mean operators under the environment of spherical fuzzy sets"],"prefix":"10.1177","volume":"41","author":[{"given":"Muhammad Sarwar","family":"Sindhu","sequence":"first","affiliation":[{"name":"Department of Mathematics, University of Management and Technology, Lahore, Pakistan"}]},{"given":"Tabasam","family":"Rashid","sequence":"additional","affiliation":[{"name":"Department of Mathematics, University of Management and Technology, Lahore, Pakistan"}]},{"given":"Agha","family":"Kashif","sequence":"additional","affiliation":[{"name":"Department of Mathematics, University of Management and Technology, Lahore, Pakistan"}]}],"member":"179","reference":[{"key":"10.3233\/JIFS-201708_ref1","doi-asserted-by":"crossref","first-page":"47","DOI":"10.1016\/j.procs.2017.11.209","article-title":"Interval linear programming based decision making on market allocations","volume":"120","author":"Aliyev","year":"2017","journal-title":"Procedia Computor Science"},{"key":"10.3233\/JIFS-201708_ref2","first-page":"23","article-title":"Sensitivity analysis of TOPSIS technique: The results of change in the weight of one attribute on the final ranking of alternatives","volume":"7","author":"Alireza","year":"2011","journal-title":"Journal of Optimization in Industrial Engineering"},{"issue":"1","key":"10.3233\/JIFS-201708_ref3","doi-asserted-by":"crossref","first-page":"87","DOI":"10.1016\/S0165-0114(86)80034-3","article-title":"Intuitionistic fuzzy sets","volume":"20","author":"Atanassov","year":"1986","journal-title":"Fuzzy Sets and System"},{"key":"10.3233\/JIFS-201708_ref4","first-page":"1","article-title":"Spherical fuzzy sets and their applications in multi-attribute decision making problems","author":"Ashraf","year":"2018","journal-title":"Journal of Intelligent & Fuzzy Systems"},{"key":"10.3233\/JIFS-201708_ref5","unstructured":"Benayoun R. , Roy B. , Sussman N. , Manual de reference du programme electre, Note de synthese et Form 25(79) (1966)."},{"key":"10.3233\/JIFS-201708_ref6","first-page":"183","article-title":"Lingenierie de la decision; Elaboration d instruments daide a la decision, La methode PROMETHEE, Quebec, Canada","author":"Brans","year":"1982","journal-title":"Presses de lUniversite Laval"},{"issue":"1","key":"10.3233\/JIFS-201708_ref7","doi-asserted-by":"crossref","first-page":"235","DOI":"10.3233\/JIFS-191374","article-title":"A novel q-rung orthopair fuzzy TODIM approach for multi-criteria group decision making based on Shapely value and relative entropy","volume":"40","author":"Chen","year":"2021","journal-title":"Journal of Intelligent and Fuzzy Systems"},{"key":"10.3233\/JIFS-201708_ref8","first-page":"1","article-title":"Picture fuzzy sets, a new concept for computational intelligence problems, Published in proceedings of the third world congress on information and communication technologies.
