The benefits provided by a model of system dynamics are directly related to its correct construction. One of the main challenges in the process of building such models is that they must be able to effectively represent a specific problematic situation. Thus, the main objective of this study is to develop a multi-methodological approach, adapting the problem structuring method of strategic options development and analysis (SODA) in the initial stage of the system dynamics (SD) model. The role of each of them clearly represents the contribution of this study: the SODA in the structuring (representation) phase of the problem and proposition of alternatives and the SD in the evaluation phase of these alternatives. To illustrate its application, the multimethodological approach developed was used to simulate scenarios considering management strategies, and the various variables affecting a water supply system, including population growth, in order to evaluate more “assertive” water management strategy(s) that could have been adopted to address the water crisis (2012–2017) and analysis future scenarios. The results show that, based on the vision of specialists with enough experience for the case studied, it was possible to structure the problem, and therefore propose a set of strategies (alternatives), which were: water loss control, wastewater reuse, application of more efficient tariffs to reduce water waste, inter-basin water transfer, and awareness regarding the use of water resources. After the survey of alternatives, scenarios were simulated considering these water management strategies. Simulation results showed that actions taken on the demand side would only be effective for a short period of water scarcity, (for example, the impact of the scarcity-based tariff on water consumption reduction). For severe drought scenarios and with a water producing system heavily dependent on rainfall, such action would no longer be efficient. However, water supply management-oriented strategies, e.g., inter-basin water transfers (PISF) and wastewater reuse, are highly effective in securing water supply and preventing water supply collapse in the region. The development of this multi-methodological approach is expected to be useful to support managers in the decision-making and implementation of water management strategies.

“…Com o objetivo de mapear o pensamento de uma pessoa sobre um determinado problema, os mapas cognitivos, de acordo com Eden (2004), são caracterizados por uma estrutura hierárquica geralmente construídos em forma de um grafo, com meios e fins, além de um objetivo situado no topo da hierarquia. Destaca-se que para a análise avançada do mapa cognitivo realizado nesse trabalho, utilizou-se a metodologia apresentada por Santos et al (2011).…”

A importância da logística reversa vem crescendo nos últimos anos, motivada dentre outros fatores, pelas exigências legais e pela oportunidade de melhorar a imagem da empresa e valorizar a sua marca. O canal reverso se caracteriza pela existência de diversas atividades, desde a coleta do material a ser retornado até a destinação ou disposição final do mesmo. Neste sentido, a armazenagem aparece como um elo fundamental no desenvolvimento das operações na logística reversa. A fim de garantir a eficiência das operações de armazenagem é importante realizar medições de desempenho adequadas. Dessa forma, esse trabalho tem por objetivo propor medidas de avaliação de desempenho das operações internas de armazenagem do canal reverso, através de um estudo de caso em uma empresa do setor de distribuição de bebidas. Para atender ao objeto proposto, fez-se uso da metodologia de mapa cognitivo. Por meio deste trabalho, a empresa objeto de estudo será capaz de avaliar o desempenho de suas operações reversas de armazenagem através de métricas que retratam a realidade de seus processos.
