This paper presents two optimization methods of an interior permanent magnetic motor (IPM). The first method is based on the non-dominated sorting genetic algorithm II (NSGA-II), while second one NSGA-III algorithm. focus reduction cogging torque (CT), which acts upon rotor when IPM not powered, and current that flows through three windings 0. influence CT over operation a negative one, inducin...

Abstract This work addresses the use of a MO optimization algorithm to deal with reliability problem in order determine redundancy and each component system. Often, these problems are formulated as single-objective mixed variables (real-integer) is subject various design constraints. Classical solution approaches were limited most recent based on nature-inspired algorithms which belong artifici...

We address the problem of optimizing a spacecraft trajectory by using three different multi-objective evolutionary algorithms: i) Non-dominated sorting genetic algorithm, ii) Pareto-based ranking genetic algorithm, and iii) Strength Pareto genetic algorithm. The trajectory of interest is an orbit transfer around a central body when the spacecraft uses a lowthrust propulsion system. We use a Lya...

We present a multiobjective genetic algorithm that incorporates various genetic algorithm techniques that have been proven to be efficient and robust in their problem domain. More specifically, we integrate rank based selection, adaptive niching through coevolutionary sharing, elitist recombination, and non-dominated sorting into a multiobjective genetic algorithm called ERMOCS. As a proof of c...

To improve customer satisfaction of cold chain logistics fresh agricultural goods enterprises and reduce the comprehensive distribution cost composed fixed cost, transportation cargo damage refrigeration time penalty a multi-objective path optimization model products considering client is constructed. The solved using an enhanced Elitist Non-dominated Sorting Genetic Algorithm (NSGA-II), differ...

The process of intelligent multi-objective parametric optimization design for mirrors is discussed in detail this paper, with the error mirror surface shape and total mass being examined as objectives. establishment complex objective functions solving problem was realized, manual modification model avoided. Moreover, combining a non-dominated sorting genetic algorithm (NSGA) helped Pareto front...

In this paper, a novel mathematical model for a preemption multi-mode multi-objective resource-constrained project scheduling problem with distinct due dates and positive and negative cash flows is presented. Although optimization of bi-objective problems with due dates is an essential feature of real projects, little effort has been made in studying the P-MMRCPSP while due dates are included i...
