Climate change and the increasing population of countries have made the importance of greenhouses more important for future food security. One of the most important considerations in greenhouse production is the need of energy to create suitable greenhouse conditions. Therefore, in this paper, the problem of greenhouse energy planning with a focus on renewable energies will be investigated. To ...
In recent years, mobile networks have faced with the increase of traffic demand. By emerging mobile applications and cloud computing, Mobile Cloud Computing (MCC) has been introduced. In this research, we focus on the 4th and 5th generation of mobile networks. Data Centers (DCs) are connected to each other by high-speed links in order to minimize delay and energy consumption. By considering a ...
iran is one of the most energy-rich countries subsidizing energy carriers, especially in the agricultural sector, to the extent that the resulting growth is at the expense of the environment. this study tries to investigate the potential impacts of energy price reform on the agro-environment, based on the marginal abatement costs (macs) of emissions. firstly, the energy demand function of the a...
: In water distribution networks, a significant amount of electricity is used to pump the water into the tanks. Planning and pump schedule could have an important role in energy consumption management and reducing the related cost. The aim of this study is to determine the optimal pump schedule on a 24-hour basis in which aims to minimize the cost of electrical energy, whilst meeting the requir...
the implementation of economic projects by targeting the subsidies can have a great effect on the costcompetitiveness of the industries and their products. the global steel industry has been considered as a basickey industry in the industrialized countries. it is also among the industries that may be seriously affected by theenforcement of subsidies. this industry, requiring energy and high-tec...
Growing concern in the management of energy due to the increasing energy costs, has forced managers to optimize the amount of energy required to provide products and services. This research integrates an energy-based resource investment project-scheduling problem (RIP) under a multi-skilled structure of the resources. The proposed energy based multi skilled resource investment problem (EB-MSRIP...
The deployment of multi-carrier energy systems, which are called energy hubs, is one of the most recent and useful strategies in the field of energy systems. The reliability of energy systems and their operation cost and efficiency could be improved by applying the concepts of energy hubs. The simultaneous management of electrical consumptions and heat demands by the concepts of energy hub woul...
