A new NBI-style Tchebycheff approach has been adopted in [68] coping with portfolio optimization problems.
Therefore the solution of multi objective problem can be solved by using the following Tchebycheff problem (26) (Shi & Xia 1997, Osman, Abo-Sinna et al.
Para calcular el numero de simulaciones se utilizo el teorema de Tchebycheff [5]:
For the second part of MOORA the Reference Point Theory is chosen with the Min-Max Metric of Tchebycheff as given by the following formula (Karlin; Studden 1966: 280):
MOEA/D uses Tchebycheff decomposition approach [33] to convert the problem of approximating the PF into a number of scalar optimization problems.
In this paper, both weighted sum and Tchebycheff decomposition approaches are used.
Every element of the ratio matrix is recalculated and final rank is given according to deviation from the reference point and Min-Max Metric of Tchebycheff (Karlin and Studden, 1966, p.
This matrix is subject to the Min-Max metric of Tchebycheff (Karlin, Studden 1966):
Whereas the Ratio System and the Full Multiplicative Form are fully compensatory methods, the Reference Point is the method based on the Min-Max metric of Tchebycheff and thus identifies certain alternatives peculiar with relative backwardness in either of criteria.
Por su parte, las aplicaciones de la programacion multiobjetivo en la administracion de la calidad del agua no son demasiado frecuentes, destacan los trabajos de Steuer y Wood (1986) que consideran el metodo de Tchebycheff de la programacion 0-1 para conseguir agua de calidad y Lai, Lin y Hwang (1994) quienes desarrollaron una tecnica para ordenar preferencias por similitud con un metodo de solucion ideal para desarrollar en el valle del rio Bow.
Para las mediciones de temperatura y flujo del aire se utilizo el metodo Tchebycheff [10], la distribucion de los puntos de medicion se muestra en la Figura 2 para un ducto rectangular y para la descarga del ventilador de la maquina comercial, el caudal de aire se obtuvo multiplicando el promedio de los valores medidos con dicha distribucion por el area.
