This dissertation presents multi-objective multi-task learning, a new learning framework. Given a fixed sequence of tasks, the learned hypothesis space must minimize multiple objectives. Since these objectives are often in conflict, we cannot find a single best solution, so we analyze a set of solutions. We first propose and analyze a new learning principle, empirically efficient learning. From...
Heuristic optimizers are an important tool in academia and industry, and their performance-optimizing configuration requires a significant amount of expertise. As the proper configuration of algorithms is a crucial aspect in the engineering of heuristic algorithms, a significant research effort has been dedicated over the last years towards moving this step to the computer and, thus, make it au...
Resource allocation is the optimal distribution in a limited number of resources available for certain activities. The large activities requires exponentially multiplying computation cost. Therefore, resource problem known as NP-Hard literature. In this study, multi-objective binary artificial bee colony algorithm has been proposed solving problems. benefited from robust structure and easy impl...
در این پایان نامه بهره برداری بهینه از ریزشبکه ها با در نظر گرفتن قیود کیفیت توان مورد بررسی قرار گرفته است. موضوع اصلی در بهره برداری بهینه ریزشبکه ها تعیین میزان تولید منابع تولید پراکنده مورد استفاده در ریزشبکه می باشد. برای در نظر گرفتن قیود کیفیت توان در این پایان نامه از شاخص میزان اعوجاج هارمونیکی ولتاژ کل ( thd ) استفاده شده است. در این پایان نامه مفاهیم جدیدی از کنترل ریزشبکه ها بصورت ...
این تحقیق بر آن است تا با برنامه ریزی بهینه و کوتاه مدت منابع تولید پراکنده برای روز بعد در یک شبکه توزیع 85 باسه استاندارد با استفاده از الگوریتم ژنتیک، تلفات و هزینه انرژی تولیدی شبکه را کاهش داده و همچنین پروفیل ولتاژ را بهبود بخشد. در این تحقیق منابع تولید پراکنده شامل فتوولتاییک و توربین بادی و همچنین بار مصرفی در هر ساعت شبانه روز مدلسازی شده اند و بر اساس این مدلها، رنج تغییرات پارامترها...
arguably, the natural gas transmission pipeline infrastructure in iran represents one of the largest andmost complex mechanical systems in the world. the optimization of large gas trunk lines known asigat results in reduced fuel consumption or higher capability and improves pipeline operation. in thecurrent study, a single-objective optimization was conducted for khormoj compressor station on t...
today, transportation of hazardous materials (i.e., hazmat) is a very important issue for researchersdue to the risk of this transit, which should be considered for development of industries and transportation.therefore, a model that is useful should consider the risk and damage to humanitarianand environmental issues due to transit of hazmat materials. by considering the related cost, thereali...
diesel engine emission standards are being more stringent as it gains more publicity in industry and transportation. hence, designers have to suggest new controlling strategies which result in small amounts of emissions and a reasonable fuel economy. to achieve such a target, multi-objective optimization methodology is a good approach inasmuch as several types of objective are minimized or maxi...
