Design of a System Dynamics Model to Analyze the Styrene Demand in the Brazilian Market

摘要: The growth of the petrochemical industry is based on end-user applications such as automotive and construction sectors, which are main drivers styrene market. However, use substitutes for petrochemicals a reality creates competition in petroleum products. In this sense, research aimed to design system dynamics model evaluate different scenarios, observing behavior demand over time. first phase project, greater understanding issue was created closed loops diagram elaborated. It used during second an explanatory regression validation demand. three, visualizing scenarios were designed. themselves results each scenario evaluated. designed simulated impact that substitute materials variations gross domestic product cause together with planning efficient strategies market could be evaluated scenarios. A critical analysis model’s contribution decision-making within organizations concludes study.
