[ 1 ] - الگوریتم ترکیب فازی مدل‌های پیش‌بین جریان ترافیک در حضور داده‌های اغتشاشی
پیش‌بینی جریان ترافیک یکی از راه‌حل‌های جلوگیری بروز ازدحام در بزرگراه‌ها است. با توجه به مطالعات انجام‌یافته، تاکنون یک مدل جامعی برای پیش‌بینی جریان ترافیک ایجاد نشده است که بتواند مانع وقوع ازدحام در شرایط مختلف ترافیکی شود. یک ایده جالب برای حل این مسئله، استفاده از ترکیب چندین مدل پیش‌بین متفاوت برای کاهش خطای پیش‌بینی است. در این مقاله یک الگوریتم ترکیب جدید بر اساس منطق فازی جهت پیش‌بینی...
[ 2 ] - Solar desalination plant site suitability through composing decision-making systems and fuzzy logic in Iran (using the desert areas approach)
Freshwater resources represent around 3% of all water on Earth, and less than 1% of that is available. Consideringcurrent conditions, as well as future predictions of need, freshwater resources cannot meet human needs. Thus,sweetening of the brackish water can be performed to provide freshwater for human use. Solar energy, because ofIran's climatic conditions, may be used for sweetening the bra...
[ 3 ] - The Development of Maximum Likelihood Estimation Approaches for Adaptive Estimation of Free Speed and Critical Density in Vehicle Freeways
The performance of many traffic control strategies depends on how much the traffic flow models are accurately calibrated. One of the most applicable traffic flow model in traffic control and management is LWR or METANET model. Practically, key parameters in LWR model, including free flow speed and critical density, are parameterized using flow and speed measurements gathered by inductive loop d...

[ 5 ] - Solving Environmental/Economic Power Dispatch Problem by a Trust Region Based Augmented Lagrangian Method
This paper proposes a Trust-Region Based Augmented Method (TRALM) to solve a combined Environmental and Economic Power Dispatch (EEPD) problem. The EEPD problem is a multi-objective problem with competing and non-commensurable objectives. The TRALM produces a set of non-dominated Pareto optimal solutions for the problem. Fuzzy set theory is employed to extract a compromise non-dominated sol...
