Multicriterial Optimization of the Composition of a Lubricant

Journal of Machinery Manufacture and Reliability, 2020
In this paper, a study has been performed to reveal the effect of the composition of a three-component lubricant on the consumption thereof, on the wear rate of the wheels of the rolling stock, and on the friction coefficient of the wheel-rail tribocontact by means of a simplex-lattice design that provides a minimum wear rate of wheel flanges.

Safety as Objective in Multicriterial Structural Optimization

29th International Conference on Ocean, Offshore and Arctic Engineering: Volume 2, 2010
Multicriterial design methodology with safety as one of the design objectives is presented. The aim of the paper is to analyze the influence of safety based design objectives on generated nondominated designs on the Pareto frontier. Possible improvements in nondominated designs are investigated by comparison to ones obtained with the standard design ...

GPU-Based Parallel Computations in Multicriterial Optimization

Russian Supercomputing Days, 2018
In the present paper, an efficient approach for solving the time-consuming multicriterial optimization problems, in which the optimality criteria could be the multiextremal ones and computing the criteria values could require a large amount of computations is proposed.

A Class of Multicriterial Optimization Models with Criteria Ranged by Importance

IFAC Postprint Volumes IPPV / International Federation of Automatic Control, 1980
Abstract Study and design of complex systems often lead to the problem of multicriterial optimization. In contrast to classical optimezation multicriterial one is aimed at finding the extremums of several functionals and characterized by a problem of multiplicity of optimal solutions uncomparable to each other.

Necessary Optimality Conditions for Nonsmooth Multicriterial Optimization Problems

SIAM Journal on Optimization, 1992
Summary: Necessary optimality conditions of the first order are derived for nonsmooth non-convex constrained optimization problems where the cost mapping is vector-valued and all occurring spaces are infinite- dimensional. These necessary conditions are given in the Karush-Kuhn- Tucker formulation and hold for various optimality concepts as proper and ...
