Constrained Bimatrix Games with Fuzzy Goals and its Application in Nuclear Negotiations [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2018
Solving constrained bimatrix games in the fuzzy environment is the aim of this research. This class of two-person nonzero-sum games is considered with finite strategies and fuzzy goals when some additional linear constraints are imposed on the strategies.

Duality in Fuzzy Sigma Models [PDF]

open access: yes, 2004
Nonlinear `sigma' models in two dimensions have BPS solitons which are solutions of self- and anti-self-duality constraints. In this paper, we find their analogues for fuzzy sigma models on fuzzy spheres which were treated in detail by us in earlier work.

Data-Driven Behavior-Based Negotiation Model for Cyber-Physical-Social Systems

open access: yesIEEE Access, 2019
This paper presents an agent-based fuzzy constraint-directed negotiation (AFCN) model for cyber-physical-social systems (CPSS). The proposed AFCN model is a behavior-based negotiation framework, which involves the agents perceive the opponents' behavior ...

Optimizing Production Mix Involving Linear Programming with Fuzzy Resources and Fuzzy Constraints

open access: yesInternational Journal of Computational Intelligence Systems, 2020
In this paper, Fuzzy Linear Programming (FLP) was used to model the production processes at a university-based bakery for optimal decisions in the daily productions of the bakery. Using the production data of five products from the bakery, a fuzzy linear

A Novel Constraints Model of Credibility-Fuzzy for Reliability Redundancy Allocation Problem by Simplified Swarm Optimization

open access: yesApplied Sciences, 2021
A novel constraints model of credibility-fuzzy for the reliability redundancy allocation problem (RRAP) is studied in this work. The RRAP that must simultaneously decide reliability and redundancy of components is an effective approach in improving the ...
