Avaliação Da Incerteza De Um Indicador De Desempenho Operacional De Uma Planta Industrial

Abstract

Este trabalho visa avaliar as incertezas associadas a um indicador de desempenho operacional de consumo de água de uma planta petroquímica, a partir de dados reconciliados e usando simulações de Monte Carlo. Neste sentido, propõe-se uma metodologia de avaliação das incertezas das correntes aquosas reconciliadas, cuja principal fonte de incerteza é os valores de qualidade de informação atribuída a cada corrente, uma vez que falta redundância de informação da planta. Como resultado foi constatado que o conhecimento da incerteza de um indicador é um fator relevante para analisar devidamente quais são as metas efetivas e ações necessárias.

Sustainability Multidimensional Optimization of Multiproduct Biorefineries: The Case Study in a Sub-Saharan African Country

“…13−15 The result of a measurement is only an approximation of its value; therefore, this must be accompanied by its uncertainty, 16 which contains a range of reasonable values of the measurand. 17 Therefore, the uncertainty evaluation is used to quantify the reliability of a measurement, which is associated with the knowledge of its precision and accuracy. 18 This review proposes a multidimensional optimization model to evaluate the sustainability of biorefineries based on technical, economic, environmental, and social indicators, considering the uncertainties associated with the respective indicators.…”

“…The technical indicators of bioenergy production have been the main focus of analysis in the consulted literature. ,, Moreover, most of the studies for techno-economic, environmental, and social evaluation of multiproduct biorefineries do not consider an uncertainty evaluation of the indicators used, compromising the reliability of the results obtained for decision-making. − The result of a measurement is only an approximation of its value; therefore, this must be accompanied by its uncertainty, which contains a range of reasonable values of the measurand . Therefore, the uncertainty evaluation is used to quantify the reliability of a measurement, which is associated with the knowledge of its precision and accuracy…”
