“…These initiatives mainly focus on mobile phones (Araújo et al, 2012). A particular concern in Latin America area is the contribution of the informal collection and dismantling systems, which is widespread in several areas: some attemptsespecially in Brazil (Gutberlet, 2015;Ghisolfi et al, 2017;Echegaray and Hansstein, 2017) -are developing to include or coordinate it in the formal system aiming to avoid unfair competition and environmental problems. By analyzing the condition of Caribbean countries about WEEE management, very few information is currently available.…”

“…De esta forma, se construyen representaciones sistémicas con flechas y puntos, denominadas diagramas causales, que capturan todas las hipótesis propuestas por el modelador, desde las que se puede aprender del sistema para intervenir sobre él en el ejercicio de decisión [8,20]. El modelamiento con Dinámica de sistemas para la gestión de residuos incluyendo los RAEE, recientemente ha sido utilizado en investigaciones similares [5,[9][10][11][12]. Esta consiste en 3 etapas, conceptualización del problema, Formulación del modelo y evaluación [13].…”

This paper presents a model for the evaluation of strategies in the management of Waste Electrical and Electronic Equipment (WEEE). Waste represents a risk to public health and the environment, the dangerous type compounds that constitute them and the increase of their generation. In Colombia, there is a law of 1672 guidelines for the adoption of a policy that improves the management of WEEE. This Law proposes public management objectives, of which in this article three of them were evaluated (Reduction in generation, incentive to use, promote integrated participation). For this evaluation, a model was built using the Dynamics of Systems methodology, which allowed the establishment of the socio-environmental system structure for the generation and management of WEEE. Likewise, the evaluation scenarios were defined, the first is the initial or natural state that corresponds to the system without any strategy and the second is the system with the implementation of the strategies, which were divided into two groups. One is Economic Circular Strategies, Environmental Education and Job Promotion, and the other group contains the producer's extended liability strategies, citizenship incentives and the collection rate. Model simulations and scenario comparisons showed that the first group of strategies decreased in the generation rate of WEEE. Likewise, they allowed a second group of strategies on disposition rate. Likewise, the proposed model for the management of Waste Electrical and Electronic Equipment is useful for the evaluation of waste management strategies in different scenarios.Keywords: waste; modeling; system dynamics; public management.Evaluación de estrategias para la gestión integral de residuos de aparatos eléctricos y electrónicos ResumenEste artículo presenta un modelo para la evaluación de estrategias en la gestión de Residuos de Aparatos Eléctricos y Electrónicos (RAEE). Estos residuos representan un riesgo para la salud pública y para el medio ambiente, por los compuestos de tipo peligroso que los constituyen y el aumento de su generación. En Colombia existe desde 2013 la ley 1672 lineamientos para la adopción de una política que mejore la gestión de los RAEE. Esta Ley propone objetivos gestión pública, de los cuales en este artículo se evaluaron tres de ellos (Reducción en la generación, incentivo al aprovechamiento, promover la participación integrada). Para esta evaluación, se construyó un modelo utilizando la metodología de Dinámica de Sistemas, la cual permitió establecer la estructura del sistema socio-ambiental de generación y manejo de los RAEE. Así mismo, fueron definidos dos escenarios de evaluación, el primero es el estado inicial o natural que corresponde al sistema sin ninguna estrategia y el segundo es el sistema con la implementación de las estrategias, las cuales se dividieron en dos grupos. Uno es Estrategias de economía circular, educación ambiental y fomento de empleo, y el otro grupo contiene las estrategias de responsabilidad extendida del productor, estímulos de la ciu...

“…Employed for computer simulation modelling, SD is a methodology used for understanding the dynamic behavior of complex systems in order to analyze and solve complex problems[42]. A system is described as a set of elements continuously interaction over a period of time, [43] while the term dynamics, refers to the situation where these systems have variables that are constantly changing. Sterman, (2000) [44] states that in an SD environment, relationships and connections between the components are called the structures of the system.…”

“…SD modelling for the automotive industry utilizes the same process as used for other manufacturing industries. First, system representation is needed by both qualitative and quantitative approaches, [43], [47], [48]. The qualitative stages includes, identification of the system to be examined and the definition of its boundaries and interfaces, [43].…”

Remanufacturing is a viable option to extend the useful life of an end-of-use product or its parts, ensuring sustainable competitive advantages under the current global economic climate. Challenges typical to remanufacturing still persist, despite its many benefits. According to the European Remanufacturing Network a key challenge is lack of accurate, timely and consistent product knowledge as highlighted in a 2015 survey of 188 European remanufacturers. With more data being produced by electric and hybrid vehicles, this adds to the information complexity challenge already experienced in remanufacturing. Therefore, it is difficult to implement real-time and accurate remanufacturing for the shop floor; there are no papers that focus on this within an electric and hybrid vehicle environment. To address this problem this paper attempts to (1) identify the required parameters/ variables needed for fuel cell remanufacturing by means of interviews (2) rank the variables by Pareto analysis (3) develop a casual loop diagram for the identified parameters/ variables to visualise its impact on remanufacturing (4) model a simple stock and flow diagram to simulate and understand data and information-driven schemes in remanufacturing.
