This study aims to find the optimized parameters for surveying milling process of S50C steel in a minimum quantity lubrication (MQL) environment using support vector machine-genetic algorithm (SVM-GA). Based on experimental matrix designed by Taguchi method, surface roughness and cutting force data were collected corresponding each experiment with changes input such as speed, tooth feed rate, a...

The dense population and the large amount of domestic waste generated make it difficult to determine best route departure time for removal trucks in a city. Aiming at problems municipal solid (MSW) transportation not time, high collection costs carbon emissions, this paper studies vehicle routing problem under influence time-dependent travel traffic congestion emissions. In paper, dual objectiv...

Generating electricity near the consumption can provide more flexibility to supply various services consumers as well reduce system losses. The limited fossil fuels and air pollution are among main incentives for expansion of this technology. One perspectives proposed effective increase in these resources’ involvement is combine resources with objectives visibility relationship between distribu...

در این پژوهش مسئله زمان‌بندی کار کارگاهی منعطف با ماشین‌های موازی درنظرگرفتن معیار تولید پاک‌تر، منابع دوگانه انسان-ماشین، زمان دسترسی کارها و پردازش وابسته به سرعت ماشین‌ها بررسی می­‌شود. اهداف شامل حداقل­‌کردن مجموع جریمه‌­های دیرکرد زودکرد افزایش است. داده می‌شود تا تکمیل کاهش یابد. درحالی‌که آلودگی صوتی محیط تولیدی منجر توجه رویکرد پاک‌تر که نگرشی پیشگیرانه است، اینجا سعی شده است حداقل­کردن...

Lot streaming, is an effective technique to increase production efficiency in a productive system by splitting job into several smaller parts overlap operations between successive machines multi-stage system. In this paper, hybrid flow shop scheduling problem with lot learning effect and buffer's limitation considered. A bi-objective mathematical model presented for minimizing the total tardine...
