From Nature to Supply Chain: Exploring Biomimicry‐Based Pathways to Sustainability and Competitive Advantage

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Inspired by insights gleaned from biomimicry theory, this paper addresses the persistent lack of theoretically grounded research in sustainable supply chain management (SSCM) and examines how nature‐inspired biomimicry principles could enhance various dimensions of its competitiveness. This study's theoretical contribution lies in its proposal

Using nonstationary fuzzy sets to improve the tractability of fuzzy association rules [PDF]

open access: yes, 2013
Modern organisations now collect very large volumes of data about customers, suppliers and other factors which may impact upon their business. There is a clear need to be able to mine this data and present it to decision makers in a clear and coherent ...

How Multiple Streams Influence Agenda‐Setting for Water Reuse in Swiss Substates

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT As climate change creates significant challenges for both the environment and society, potential mitigation and adaptation solutions are widely discussed. Yet, neither challenges nor their potential solutions automatically reach the political agenda or lead to a policy decision.

REVISITING SOME FUZZY ALGEBRAIC STRUCTURES

open access: yesJournal of Computer Science and Cybernetics, 2022
Following our investigations on some fuzzy algebraic structures started in [6--8], and [9], in the present work, we revisit fuzzy groups and fuzzy ideals and introduce some new examples and then define the notion of fuzzy relation modulo a fuzzy subgroup and modulo a fuzzy ideal.

A New Algebraic Structure of Complex Pythagorean Fuzzy Subfield

open access: yesIEEE Access, 2023
The concept of complex Pythagorean fuzzy set $(\mathbf {CPFS})$ is recent development in the field of fuzzy set $(\mathbf {FS})$ theory. The significance of this concept lies in the fact that this theory assigned membership grades $\psi $ and non-membership grades $\hat {\psi }$ from unit circle in plane, i.e., in the form of a complex number ...

Robust Position Control of an Electro‐Hydraulic Actuator via Metaheuristic Optimization of a Fractional‐Order PID Controller

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this study, a robust position control strategy is presented for a two‐stage electro‐hydraulic actuator system using a fractional‐order proportional–integral–derivative (FOPID) controller tuned by Kirchhoff's law algorithm (KLA). Electro‐hydraulic systems exhibit strong nonlinearities, parameter uncertainties, and external disturbances ...

An investigation of group action on intuitionistic fuzzy primary and semiprimary ideals of Γ-ring [PDF]

open access: yesNotes on IFS
This article is a continuation of the author’s earlier work [11]. Here we extend the study of group actions on intuitionistic fuzzy structures by focusing on intuitionistic fuzzy primary and semiprimary ideals of Γ-rings.

Nonprofit Governance and Financial Stability: A Study of Government‐Funded Social Services

open access: yesNonprofit Management and Leadership, EarlyView.
ABSTRACT Nonprofit social service providers are essential in delivering vital services, often with public funding. This study adopts a contingency perspective to explore the relationship between organizational governance and financial stability in publicly funded nonprofit organizations. We use a combination of comparative multilevel analysis (CMA) and
