Multicriteria model for the integral management of urban solid waste in Quevedo -Ecuador

Abstract

The analysis of the urban solid waste supply chain reveals the main problems that affect it. This work presents a multi-criteria model for the optimization of the economic variables, environmental impact and customer satisfaction of the integral management process of urban solid waste, which facilitates the promotion of systematic improvement actions of variables or factors that intervene in the process. The model allows generating information for decision-making by municipal authorities in the canton of Quevedo-Ecuador. To achieve this, a diagnosis was made of the current conditions of the generation, transport, separation, treatment, composting and final disposal process of these wastes, identifying the relevant indicators for the current management of the same and later the multi-criteria model was elaborated including four objective functions whose goal is the optimization of the problem, considering a series of restrictions in each of the processes mentioned above. The result obtained allows minimizing the cost and use of transportation, maximizing savings in environmental impact and customer satisfaction. It is concluded that the application of the multi-criteria model allowed to verify its feasibility and rational use as an effective instrument of the decision-making process
