Multiple Machine Continuous Setup Lotsizing with Sequence-dependent Setups
Bernardo Almada-Lobo; Diego Klabjan; Maria Antónia Carravilla; José F. OliveiraWe address the short-term production planning and scheduling problem coming from the glass container industry. A furnace melts the glass that is distributed to a set of parallel molding machines. Both furnace and machine idleness are not allowed. The resulting multi-machine multi-item continuous setup lotsizing problem with a common resource has sequence-dependent setup times and costs. Production losses are pe...
Single machine multi-product capacitated lot sizing with sequence-dependent setups
Bernardo Almada-Lobo; Diego Klabjan; Maria Antónia Carravilla; José F. OliveiraIn production planning in the glass container industry, machine-dependent setup times and costs are incurred for switch overs from one product to another. The resulting multi-item capacitated lot-sizing problem has sequence-dependent setup times and costs. We present two novel linear mixed-integer programming formulations for this problem, incorporating all the necessary features of setup carryovers. The compac...
Prevalência de auto-imunidade tireoidiana em um grupo de pacientes com diabetes...
Souza,Otton Luis Raffo; Diehl,Leandro Arthur; Carleto Jr.,Lineu Domingos; Garcia,Valdinei; Carrilho,Alexandre José F.; Oliveira,Maria Leocádia deA auto-imunidade tireoidiana é uma co-morbidade freqüente entre pacientes com diabetes mellitus tipo 1 (DM1). Neste estudo, avaliamos a prevalência da positividade para auto-anticorpos anti-tireoidianos (anti-microssomal, anti-Tg e anti-TPO), bem como características clínicas (idade, sexo, duração do DM) e laboratoriais (função tireoidiana, HbA1) de 101 pacientes (idade média de 20 ± 9,6 anos; 62 do sexo femini...
