Energy is one of the primary inputs in textile processing industries that have a significant impact on the cost of a cotton product. The energy cost-share is reported between 5-10% of the total production cost of woven cotton fabric in textile factories of developed countries. However, it is far higher in developing countries. This study aims to contribute to the understanding of energy use and...

Energy consumption share in construction part and dependent industries is about 40 percent of total energy consuming in Iran which is significant compared to other industries such as transportation, agriculture and therefore is of important. As energy consumption reduction and material durability improvement leads to cost reduction from one hand and environment pollution reduction on the othe...

This paper presents an AHP and FLP model for the allocation of energy subsidies to different economic sectors. To do so, we defined a group of socio-economic criteria that may affected by the allocation of energy subsidies. These criteria are: economic growth, energy intensity, labor intensity, inflation, social cost of air pollutions and distribution of energy subsidy among socio-economic leve...

This paper demonstrates a method to how reserve capacity and cost allocation could be determined in a pool-based and disaggregated market model. The method considers both the spinning reserve and interruptible loads as the operating reserve services. In the proposed market, generators and consumers (including participation of interruptible loads) submit offers and bids to the independent system...

Management and optimization of energy consumption has been importantly considered by policy-makers in the field of energy and environment from the perspective of energy security and environmental considerations. In this study, nondominated sorting genetic algorithm (NSGAII) was applied to determine the optimal share of fossil energy sources for energy intensive industries of Iran including The ...

This article tries to analyze the effect of eliminating the electricity subsidy on the intensity of this energy in production industries during 1995-2007 using GMM dynamic panel data method. Having used the cost function with Cobb-Douglas form, it was recognized that there is a negative and significant relationship between electricity intensity and its price. Meanwhile, the increase in the pric...

One of the main goals of a medical education transition program is to estimate the cost of educating a student. The aim of this study was to estimate the final cost of student’s education in the Tabriz School of Management and Medical Informatics. The present study used the Activity Based Costing method (ABC) to calculate the cost of student education in the academic year 2015-16. After identif...
