Análise de risco econômico de dois sistemas produtivos de carvão vegetal

Abstract

This study aimed to analyze the economic viability of charcoal production in kilns-furnace system and "rabo-quente" kilns, as well as the investment risk simulation. The economic analysis was performed by determining the following indicators: Net Present Value (NPV), Equivalent Annual Value (EAV) and Benefit - Cost Reason (B/C). The risk analysis was performed by the Monte Carlo method. Economic indicators were viable. Kilns-furnace system evidenced to be more viable economically. Risk analysis indicated that there is probability to economical unviability of evaluated systems, 0.9% and 27.3% for kilns-furnace system and "rabo-quente" kilns, respectively. Inclusion of risk analysis in economic analysis of charcoal production projects results in greater security to infer on economic indicators.
