[ 1 ] - Developing Self-adaptive Melody Search Algorithm for Optimal Operation of Multi-reservoir Systems
Operation of multi-reservoir systems is known as complicated and often large-scale optimization problems. The problems, because of broad search space, nonlinear relationships, correlation of several variables, as well as problem uncertainty, are difficult requiring powerful algorithms with specific capabilities to be solved. In the present study a Self-adaptive version of Melody Search algorith...
[ 2 ] - Hydrological Assessment of Daily Satellite Precipitation Products over a Basin in Iran
In order to measure precipitation as the main variable for estimating the runoff and designing hydraulic structures, the satellite algorithm products that have the proper spatial and temporal coverage, can be used. In this study, at first, the daily streamflow simulation of Sarough-Cahy River from the Zarinehroud basin was conducted through the artificial neural network (ANN) and ground data of...
[ 3 ] - Investigating Pareto Front Extreme Policies Using Semi-distributed Simulation Model for Great Karun River Basin
This study aims to investigate the different management policies of multi-reservoir systems and their impact on the demand supply and hydropower generation in Great Karun River basin. For this purpose, the semi-distributed simulation-optimization model of the Great Karun River basin is developed. Also, the multi-objective particle swarm optimization algorithm is applied to optimize the develop...
[ 4 ] - استفاده از مدل جایگزین شبکه عصبی مصنوعی به‌منظور کاهش محاسبات شناسایی نشت در شبکه‌های آبرسانی
دست‌یابی به پارامترهای نشت در روش تحلیل معکوس جریان گذرا (ITA) به صورت معکوس و با حل یک مسئله برنامه‌ریزی غیرخطی توسط الگوریتم‌های فراکاوشی همچون الگوریتم ژنتیک (GA) انجام می‌شود. با وجود توانایی بالای روش ITA در یافتن پارامترهای نشت، استفاده از الگوریتم GA در این روش سبب می‌شود تا از نظر کارایی محاسباتی، نیازمند صرف هزینه و زمان محاسباتی زیادی باشد. دلیل این امر را می‌توان ماهیت حرکات تصادفی و...
