If x∗ is a pareto-optimal solution of a convex multi-objective optimization problem, then there exists a non-zero positive weight vector w such that x ∗ is a solution of problem (1. Robust optimization of multi-objective problems is the third and final type of uncertainty considered in this work and it involves the optimization of a set of pareto optimal solutions that. It formulates a multi-objective model where the primary objective is to minimize the sum of the artificial variables (uncovered shifts), and the secondary objective is to minimize the maximum difference in the number of shifts worked between any pair of workers.

Multiobjective optimization involves minimizing or maximizing multiple objective functions subject to a set of constraints example problems include analyzing design tradeoffs, selecting optimal product or process designs, or any other application where you need an optimal solution with tradeoffs.
A multi-objective optimization method is presented for estimating the parameters of finite element structural models based on modal residuals the method results in multiple pareto optimal structural. In the present paper a mathematical model for a mini-channel heat exchanger is proposed multiobjective optimization using genetic algorithm is performed in the next step in order to obtain a set. Problem can be solved by using taughis optimization procedure as multi objective function model the mathematical models can be represented by y= f (v,n,d) (1.

This paper presents a multi-objective optimization model in optimizing the operation of natural gas pipeline networks a mathematical model is established for different network configurations, namely linear, branch and looped topologies.
In mathematics, computer science and operations research, mathematical optimization or mathematical programming, alternatively spelled optimisation, is the selection of a best element (with regard to some criterion) from some set of available alternatives. Firstly, the multi-objective optimization mathematical model of product configuration is constructed, the objective func- tions are performance, cost, and time. Mathematical models have been developed to assess and /or optimize sc performance previous researches on sc optimization have been considering two forms: single objective (so) and multi-objective (mo.  p zanchetta, heuristic multi-objective optimization for cost function i = 1, , 8, the coefficients of the discrete-time input filter weights selection in finite states model predictive control, in proc on.
