In multi-label classification (MLC), each instance is associated with a subset of labels instead of a single class, as in conventional classification, and this generalization enables the definition of a multitude of loss functions. Indeed, a large number of losses has already been proposed and is commonly applied as performance metrics in experimental studies. However, even though these loss fu...

در دیدگاه مرسوم و گذشته، مدیران زنجیره تأمین به دنبال تحویل سریع¬تر کالا و خدمات، کاهش هزینه و افزایش کیفیت بودند اما بهبود عملکرد زیست محیطی زنجیره تأمین و اهمیت هزینه¬های اجتماعی و تخریب محیط زیست لحاظ نمی¬گردید. با فشار مقررات دولتی برای اخذ استانداردهای زیست محیطی از یک طرف و رشد فزاینده تقاضای مشتریان برای عرضه محصولات سبز (بدون اثر مخرب بر محیط زیست) مفهوم زنجیره تأمین سبز و مدیریت آن را ...

In recent years, the optimization of multi-objective service composition in distributed systems has become an important issue. Existing work makes a smaller set Pareto-optimal solutions to represent Pareto Front (PF). However, they do not support complex mapping quality (QoS) objective space, thus having limitations providing representative solutions. We propose enhanced differential evolution ...

In this paper, a novel compensator based on Magnetically Controlled Reactor with Fixed Capacitor banks (FC-MCR) is introduced and then power system stability in presence of this compensator is studied using an intelligent control method. The problem of robust FC-MCR-based damping controller design is formulated as a multi-objective optimization problem. The multi-objective problem is concocted ...

in this paper, a non-dominated sorting genetic algorithm-ii (nsga-ii) based approach is presented for distribution system reconfiguration. in contrast to the conventional ga based methods, the proposed approach does not require weighting factors for conversion of multi-objective function into an equivalent single objective function. in order to illustrate the performance of the proposed method,...

vendor managed inventory is a continuous replenishment program that is designed to provide major cost saving benefits for both vendors and retailers. previous research on this area mainly included single objective optimization models where the objective is to minimize the total supply chain costs or to maximize the total supply chain benefits. this paper presents a bi-objective mathematical mod...
