óptimo minimizando los
tiempos de producción. Esquema de las
estaciones de trabajo Modelización Función objetivo
MIN W = 8*Y11 + 10*Y12 + 2.5*Y21 + 2*Y22 + 5*Y31 + 5.6*Y32 + 8*Y41 + 9*Y42 + 10*Y43 + 11*Y44 + 7.5*Y51 + 6*Y52 Productos Objetivo Restricciones Operaciones en cada estación de trabajo Y11 + Y12 =1
Y21 + Y22 = 1
Y31 + Y32 = 1
Y41 + Y42 + Y43 + Y44 = 1
Y51 + Y52 =1 Precedencia Y21 + Y22 - Y11 - Y12 = 0
Y31 + Y32 - Y21 - Y22 = 0 Y41 + Y42 + Y43 + Y44 - Y31 - Y32 = 0
Y51 + Y52 - Y41 - Y42 -Y43 - Y44 = 0 Y41 + Y22 <= 1 Y42 + Y31 <= 1 Disposición Conclusión Tiempo óptimo: 29, 5 minutos. Problema abierto: extensión del modelo a la minimización del tiempo integrando varios productos.
