در این مقاله یک مدل ریاضی برای مسئله سیستم تولیدی همکارانه ساخت بر اساس سفارش با رعایت انصاف تخصیص بار‌های تولید طراحی شده است. اهداف اصلی مدل، کمینه‌سازی هزینه‌‌های کل و حداکثر استفاده از منابع به‌منظور عادلانه شرایط عدم­قطعیت کنترل پارامتر‌های غیرقطعی روش برنامه‌ریزی فازی ‌شده نتایج نشان می‌دهد افزایش نرخ عدم‌قطعیت، می­یابد. ازآنجاکه ظرفیت کارخانه‌ها ثابت است، مقدار تقاضا، هر کارخانه نیز می­ی...

Synthetic Aperture Radar (SAR) is one of active microwave sensor could work all weather and day/night time. This system can observe the objects on ground surface, and obtain microwave image by SAR image processing. SAR needs modulated signal like chirp pulse for high resolution and preciseness. In the case of UAV, some pulse parameter, i.e. bandwidth etc, should be changed to adequate value dur...

We investigated the impact of climate change on the number of wildfires in the Peak District uplands of northern England. Wildfires in peat can result in severe carbon loss and damage to water supplies, and fighting such fires is difficult and costly in such a remote location. The Peak District is expected to experience warmer, wetter winters and hotter, drier summers. Local weather simulations...

Consumer telecommunication integrated circuits and wireless communication devices, such as cell phone systems and wireless local area network systems, require high-performance analog and radio frequency (RF) integrated circuits (ICs). As the technology advances, nowadays billions of transistors can be integrated into one single chip. Placement is essential to both digital and analog integrated ...

We examine seasonal and spatial variations of stochastic-weather-generator (SWG) parameters and their impact on simulated weather sequences. Using daily weather observations from 29 stations across the contiguous United States, we estimate monthly station-specific parameters that are compared with the constant parameters that frequently are used in SWG applications. A WGENtype SWG is then used ...

Many methods to generate future weather files run building performance simulations have been proposed. However, do not account for local urban climate modifications, such as heat island and may be representative of buildings’ conditions. This study describes a methodology include effects in using multiple tools: the EURO-CORDEX regional model data, Urban Weather Generator, URBVENT canyon wind m...

This study develops a methodological framework to analyze the climate sensitivity as well as climate change impacts on outdoor recreation activities, applied to a case study of 2 lidos in the city of Zurich. A negative binomial regression is used to link daily data on lido entries with weather variables for the period 2003 to 2010, while controlling for non-climatic factors (such as weekends an...

One of the main challenges in automatically generating textual weather forecasts is choosing appropriate English words to communicate numeric weather data. A corpus-based analysis of how humans write forecasts showed that there were major differences in how individual writers performed this task, that is, in how they translated data into words. These differences included both different preferen...

CLIGEN is a stochastic weather generator to produce daily variables to drive process-based runoff and erosion prediction models such as WEPP. Algorithms were developed to compute the R-factor, its monthly distribution, and 10-year storm erosion index (EI) needed to apply the revised Universal Soil Loss Equation (RUSLE) using stochastically generated weather variables. Measured R-factor and 10-y...
