Multi-Attribute Decision Support Model Based on Bijective Hypersoft Expert Set

Soft set tackles a single set of attributes whereas its extensionhypersoft set is projected for dealing attribute-valued disjoint sets corresponding to distinct attributes with entitlement of multi-argument approximate function. In order to furnish soft set-like models with multi-decisive opinions of multi-experts, a new model i.e. soft expert set has been developed but this is inadequate for handling the scenario where partitioningof attributes into their respective attribute-valued sets is necessary. Hencehypersoft expert set has made its place to be developed. This article intendsto develop a new type of hypersoft set called bijective hypersoftexpert set which is more flexible and effective. After characterization ofits essential properties and set-theoretic operations like union, relaxed andrestricted AND, a decision-support system is designed which is characterizedby new operations such as decision system, reduced decision system,etc. with illustrated examples. The proposed decision-support system isapplied in multi-attribute decision-making process to manage a real-lifeapplication.AMS (MOS) Subject Classification Codes: 91B06; 93E25Key Words: Soft set, Soft expert set, Bijective soft set, Hypersoft set, Hypersoft expertset, Bijective hypersoft set, Bijective hypersoft expert set
