در این پایان نامه الگوریتم های مختلفی برای پیشبینی توان تولیدی سامانه های فتوولتائیک، برای بازه زمانی 10 دقیقه آینده، با استفاده از سری زمانی از داده های مربوط به تولید توان این سامانه ها پیشنهاد شده و مورد ارزیابی قرار میگیرند. نتایج نشان میدهد که عملکرد الگوریتمها برای روزهای آفتابی و ابری یکسان نیست. با این حال در میان این الگوریتمها، نتایج شبیهسازی نشان میدهد که مدل ( auto-regr...
We address a novel integrated maintenance and production scheduling problem in a multi-machine and multi-period production system, considering maintenance as a long-term decision. Deterioration of machines over time decreases production capacity. Since maintenance activities improve machine conditions, increasing production capacity, but also take time that cannot be used for production, the ch...
Analysing and modelling efforts on production throughput are getting more complex due to random variables in today’s dynamic production systems. The objective of this study is to take multiple random variables of production into account when aiming for production throughput with higher accuracy of prediction. In the dynamic manufacturing environment, production lines have to cope with changes i...
In recent years, Supplying sustainable water resources in waterless areas can be considered as some of the major problems in Iran. Presently, there are two conventional systems for desalination technique i.e MED and RO to produce drinkable water, eventhought each ones have its advantages and disadvantages. In this research two integrated system including series and parallel configurations of ...
Typical models of the production inventory systems assume that lot sizes of raw materials and final products are treated separately which leads to suboptimization production process. In this paper, a unified inventory model of an integrated production inventory system, where each of production, demand and deterioration rates are general functions of time, is considered. Shortage for the final p...
