“…Por otra lado, una de las iniciativas que las industrias han empleado para generar desarrollo sostenible es la de implementar cadenas de suministro cerradas que esencialmente combinan la logística directa con logística inversa, es decir, estas cadenas de suministro cerradas pueden reducir sustancialmente la generación de residuos sólidos acorde a las perspectivas de distribuidores y sistemas de reciclaje (Lipan et al, 2017;Zhao et al, 2019); en otras palabras, satisfacer la demanda y, al mismo tiempo, recolectar y recuperar productos devueltos o usados (Alegoz et al, 2020) teniendo en cuenta que los seres humanos generan residuos en sus actividades diarias. En Ecuador se generan alrededor de 4 millones de toneladas por año, de las cuales se hacen esfuerzos para recuperar la mayor cantidad de residuos potencialmente reciclables, ya que una disposición final de dicha cantidad de residuos llevaría a un colapso de los rellenos sanitarios disponibles (Alarcón, 2017).…”

El presente artículo se enmarca en el reciclaje como motor de desarrollo para los actores presentes en esta industria, enfatizando en aquellos que intervienen en la cadena de suministro de papel y cartón en la ciudad de Cuenca-Ecuador. La metodología empleada, con carácter cuantitativo-inductivo de corte transversal, no experimental, tiene como objetivo usar el Método Analytic Hierarchy Process (AHP) (Saaty, 1980) aplicando criterios adaptados a realidades y particularidades presentes en dicha cadena de suministro. Finalmente, esto permite la selección de criterios para futuras evaluaciones de una gestión eficaz de la cadena de suministro respecto a la toma de decisiones gerenciales.

“…Hu et al [37] discussed two additional government subsidies in a CLSC considering capand-trade regulations, namely, policy bias and direct subsidy and concluded that there is little difference in the impact of the two types of government subsidies on the CLSC. Alegoz et al [38] analyzed and compared three different carbon policies, and found the optimal decision for each member of the CLSC under the three emission policies. Mohammed et al [39] compared and analyzed the various carbon regulation mechanisms implemented for carbon emissions in CLSCs and proposed a model that improves the overall benefits and emissions of CLSCs.…”

In the current context of resource scarcity and increased pollution, enterprises need to better allocate capacity and achieve carbon emission reduction. We examine the optimal decision problem for a closed-loop supply chain (CLSC) considering capacity constraints and stochastic demand under a cap-and-trade system. A two-level CLSC comprising a supplier and a manufacturer is established. To make the model more realistic, we treat demand as a random variable, consider the manufacturer’s production capacity within a certain upper limit, and allow the manufacturer to make investments to expand capacity to complete production demand. Based on this CLSC, the collection activities of the supplier and manufacturer are considered. Meanwhile, government carbon limits and carbon trading controls on the manufacturer are considered based on carbon reduction by enterprises. Through modeling and analysis, optimal decisions are derived for the amount of capacity investment, level of carbon emission reduction, and collection price variables. The results indicate that supplier collection has a positive effect on the sustainability of the CLSC. Moreover, the government’s carbon quota and carbon trading control of manufacturers can effectively reduce the carbon emissions of the CLSC, encourage enterprises to reduce carbon emissions, and improve the sustainability of the CLSC.

“…Therefore, some important parameters such as customer demands are completely unclear and appropriate planning to deal with this uncertainty seems necessary. In this connection, studies on the design of a stable CLSC under uncertainty have attracted the attention of researchers, which can be referred to (De et al, 2020;Alegoz et al, 2020;Pham, 2021). In a stable CLSC, financial factors are important because they have a greater impact on supply, production, distribution, and recycling.…”

In this paper, a stable CLSC problem is modeled in conditions of uncertainty and indeterminacy. The SCN is designed to maximize NPV and minimize carbon releases by maintaining environment friendly policies and accounting for increase. To achieve a suitable model for designing a stable CLSCN and making important decisions such as selecting the right suppliers, selecting the type of transport, initial the facility, the optimal flow between facilities and accomplishing an efficient solution to the problem decision making, the neutrosophic optimization method is used. The results of experiments that discuss and evaluate different scenarios confirm the efficiency and validity of the proposed model. The findings also show that the effective improvement of the obtained solutions by reducing the solution time up to twenty percent can be responsible for large-scale problems in different scenarios. This paper uses a neutrosophic optimization method to solve the problem of designing a stable CLSCN under uncertainty and indeterminacy.
