TL;DR: In this paper , the authors evaluated the performance and efficiency of 49 Islamic banks across 10 countries during 2019-2020 to assess how those banks can preserve their performance and remain resilient in the aftermath of the COVID•19 pandemic.

TL;DR: In this paper , the impact of retailer's risk aversion on the equilibrium strategies and channel coordination in the presence of consumers' low-carbon preference is examined, and an option and cost-sharing combined contract is proposed to coordinate the supply chain.

TL;DR: The demonstration of global research trends in CO can support researchers in identifying the relevant issues regarding this expanding and transforming research area.

TL;DR: In this article , the authors construct three models to examine the operation strategy in an E-commerce platform supply chain by considering live streaming services, and they show that introducing streaming services is always beneficial for both the Ecommerce platform and streaming services supplier.

TL;DR: In this paper, the authors argue that DEA benchmarking models should incorporate into their objectives criteria for the selection of suitable benchmarks among peers, in addition to considering the setting of appropriate targets (as usual).

TL;DR: In this article, the authors have been supported by FCT-Fundacao para a Ciencia e a Tecnologia-within the Project Scope UID/CEC/00319/2019 and grant SFRH/BD/90558/2012.

TL;DR: In this article , a branch-and-cut algorithm for irregular strip packing with uncertain demand for the items to be cut is presented, where the strip is discretized over a mesh of points in the model and constraints to ensure items are non-overlapping based on the concepts of inner-fit raster and no-fit Raster.

TL;DR: In this article , the online retailer's optimal choice of selling mode is mainly affected by the direct selling cost under Bertrand competition, whereas it is affected jointly by the indirect selling cost, competition intensity, and commission rate under Cournot competition.

TL;DR: This work builds upon [16], which studied Γ-robustified LCPs for `1 and box-uncertainty sets, whereas it now focuses on ellipsoidal uncertainty set.

TL;DR: In this paper , the authors present a rigorous, component-based analysis of six widespread metaphor-based algorithms for tackling continuous optimization problems, deconstructing the six algorithms into their components and relating them with equivalent components proposed in well-established techniques, such as particle swarm optimization and evolutionary algorithms.

TL;DR: In this paper, a unified variational inequality framework was developed for spatial price network equilibrium problems that handles multiple products with multiple demand and supply markets in multiple countries as well as multiple transportation routes.

TL;DR: In this article, instead of the maximization of the profit per unit time, or the minimizing of the average inventory cost, the objective is to maximize the return on inventory investment, defined as the average profit divided by the average cost.
