Abstract

1 / 1 resumo “processo de monitoramento de uma degradaã‡ãƒo de um dispositivo integrado de uma aeronave” um processo de monitoramento de uma degradaã§ã£o de um dispositivo integrado de uma aeronave compreendendo uma etapa de comparaã§ã£o de uma marcaã§ã£o de anormalidade obtida para um voo dado da aeronave a um limiar de decisã£o (s) e uma etapa de emissã£o de um alarme em caso de ultrapassagem do limiar de decisã£o (s), o limiar de decisã£o (s) sendo determinado automaticamente para uma probabilidade de alarme dada pa, correspondente ã  probabilidade que um alarme seja emitido no curso do processo de monitoramento enquanto que o dispositivo integrado ã© nã£o danificado, por meio das etapas seguintes: uma etapa de cã¡lculo de uma pluralidade de marcaã§ãµes de anormalidade para uma pluralidade de voos da aeronave sem degradaã§ã£o de maneira a obter uma distribuiã§ã£o da densidade de probabilidade da marcaã§ã£o de anormalidade, a distribuiã§ã£o sendo prã³pria para a natureza fã­sica do dispositivo integrado; uma etapa de ajuste da distribuiã§ã£o por um estimador nã£o paramã©trico da densidade de probabilidade de maneira a obter uma funã§ã£o de distribuiã§ã£o ajustada contã­nua; uma etapa de cã¡lculo de uma funã§ã£o de repartiã§ã£o ajustada contã­nua a partir da funã§ã£o de distribuiã§ã£o ajustada contã­nua; e uma etapa de leitura do antecedente da funã§ã£o de repartiã§ã£o ajustada contã­nua para o valor 1-pa, o antecedente correspondendo ao limiar de decisã£o (s).
