New variants of fuzzy optimal control problems

Asian Journal of Control, EarlyView.
Abstract This study introduces a groundbreaking approach to optimal control problems by incorporating fuzzy conformable derivatives. Our primary goal is to identify the optimal control strategy that maximizes fuzzy performance indices while adhering to fuzzy conformable dynamical systems.

Ulam‐type stability of ψ− Hilfer fractional‐order integro‐differential equations with multiple variable delays

Asian Journal of Control, EarlyView.
Abstract We study a nonlinear ψ−$$ \psi - $$ Hilfer fractional‐order delay integro‐differential equation ( ψ−$$ \psi - $$ Hilfer FrODIDE) that incorporates N−$$ N- $$ multiple variable time delays. Utilizing the ψ−$$ \psi - $$ Hilfer fractional derivative ( ψ−$$ \psi - $$ Hilfer‐FrD), we investigate the Ulam–Hyers––Rassias (U–H–R), semi‐Ulam–Hyers ...

No‐regret and low‐regret control for a weakly coupled abstract hyperbolic system

Asian Journal of Control, EarlyView.
Abstract This paper explores an optimal control problem of weakly coupled abstract hyperbolic systems with missing initial data. Hyperbolic systems, known for their wave‐like phenomena and complexity, become even more challenging with weak coupling between subsystems.

On qualitative analysis of an ecological dynamics with time delay

Asian Journal of Control, EarlyView.
Abstract In this paper, we study a fractional‐order predator–prey system with time delay, where the dynamics are logistic with prey population commensurate to the carrying capacity. Mainly, by linearizing the system around the equilibrium point, we first analyze the stability and then prove the existence of Hopf bifurcation.

Interval‐valued Caputo–Fabrizio fractional derivative in continuous programming

Asian Journal of Control, EarlyView.
Abstract This study investigates a novel class of variational programming problems characterized by fractional interval values, formulated under the Caputo–Fabrizio fractional derivative with an exponential kernel. Invex and generalized invex functions are used to discuss the Mond–Weir‐type dual problem for the considered variational problem.

Development of a consolidated bioprocess for the production of citric acid using Aspergillus niger as biocatalyst

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The industrial production of citric acid, an ingredient in beverages, pharmaceuticals, and cosmetics, is based on microbial fermentation of glucose or sucrose. Given the elevated cost of these sugars, lignocellulosic biomass is emerging as a cost‐effective and environmentally friendly feedstock for sustainable bioprocesses.

Can Sustainability Disclosure Affect Crowdfunding Success?

Business Strategy and the Environment, EarlyView.
ABSTRACT Sustainability has emerged as a critical element in entrepreneurial finance, yet its role in reward‐based crowdfunding (RBC) remains underexplored. Existing studies on sustainability and crowdfunding primarily focus on equity‐based models, specific project types, or single‐country analyses, leading to mixed findings and limited ...

Balancing Barriers and Enablers: Swedish SMEs' Journey Toward Contributing to SDGs

Business Strategy and the Environment, EarlyView.
ABSTRACT Swedish multinational SMEs contribute to sustainable development goals (SDGs) by implementing various business processes and practices that are internal and external to the organization. However, research related to SDGs and business practices contributing to their implementation often focuses on large enterprises, whereas small‐ and medium ...

Illuminating the Field of Sustainable Ecosystems: Framing the Evolution and Future Through Bibliometric and Theme Analyses

Business Strategy and the Environment, EarlyView.
ABSTRACT Recent years have witnessed rapid growth in academic literature on ecosystems related to sustainability. However, existing studies have treated different types of ecosystems as separate research streams, resulting in fragmented knowledge. Additionally, there are still blind spots regarding the foundational works and emerging themes that should
