The intermediary between Consumer and market of Natural gas is long transportation pipeline. Analysis of different dimension is a prerequisite for constructing these infrastructures. This study has been done in the fields of economics, environment and energy security. The proposed pipeline, which is called Islamic pipeline, passes through different countries, Iraq, Syria, Greece and Italy. It carries natural gas and feeds Europe gas requirements, also passes the Mediterranean Sea, which includes underwater pipe-laying technology that has been considered. Economic analysis of this project calculated, using Cost-Benefit analysis. Environmental issues has been identified and classified,... 

Car usage-based insurance is recently introduced to the market of car insurance and because these contracts are new in this market, Insurers and other beneficiaries are eager to know about the outcome of them. In this study, the outcome of these contracts and equilibrium of the market have been analyzed from the view of insurers. An insurer as a profitable firm want to analyze its costs and benefits, and as a result, one of the most important factors from the view of the insurer is the cost-benefit analysis when the insurer enters into the new market of usage-based insurance. For this analysis, by contract selection and insurer loss payment data, insurer cost and benefit forecasting models... 

Despite there are many publications and press on the benefits and costs of dams from a purely single-discipline perspective, but recent studies simultaneously assess biophysical, economic, and social issues as well as concepts related to political geography about dams. The purpose of this study is to model the benefits and costs of constructing a dam from a multi-field perspective. The Integrative Dam Assessment Modeling (IDAM) is designed to integrate biophysical, economic, social and political geography perspectives into a single cost-benefit analysis of dam construction. In particular, a new tool of integrative dam assessment model has been proposed to evaluate the costs and benefits... 

Most of the energy consumed in the country is spent on heating and cooling of buildings. The use of various materials in building construction can have a significant impact on reducing energy waste and the cost of consuming gas and electricity. One of the ways to increase the quality and efficiency of resources, including energy saving, is to use industrial and semi-industrial materials. The purpose of this study is to compare the use of traditional, semi-industrial and industrial materials in the external wall of the building in terms of energy consumption and utilization costs, taking into account the initial cost of energy and the cost of energy during the operation period. In this... 

Current trend of energy consumption and aging infrastructure of electricity grids mandates high amounts of investment in transmission and distribution networks. On the other hand, with increased awareness about environmental issues, share of renewable energy resources in power generation portfolio has risen in recent years. Microgrids, as one of the most promising solutions to tackle these issues, are able to accommodate high penetration levels of renewable energy sources and distributed generation in distribution systems. However, microgrids sizes are limited due to some operational considerations and as a result, efficient management of distribution systems with high penetration of... 

Meeting the energy demand of agricultural greenhouses has turned out to be the most important challenge of greenhouse cultivation. In this study, it is proposed to use the concept of industrial symbiosis between agricultural greenhouses and biogas plants to face this challenge. The main purpose of the study is to investigate the potential clean greenhouse area that may be supported by the proposed symbiotic network, in order to provide a decision-making tool for the relevant policymakers. The methodology is based on the agent-based input-output matching economic analysis. The amount of biogas produced by poultry and cattle manure is estimated to be 0.6 (m3 / kg VS) and 0.47 (m3 / kg VS)... 

Electric energy distribution system (DS) reliability has a great impact on the quality of service provided to customers. On the other hand, improving the reliability performance in a DS is an expensive task. So, determining an efficient and economical target for the reliability of DSs is imperative. This thesis aims to determine efficient and economical reliability targets for reliability indices of DS based on data envelopment analysis (DEA) considering distribution feeders as the decision-making units (DMUs). For this sake, using the fuzzy c-mean (FCM) method, feeders are clustered and the membership degrees are determined so that the target associated with each feeder gets greater impact... 

The Cost/Benefit Analysis (CBA) is considered to be among the chief and most widely used analytical tools in the realm of public policy and particularly environmental and climatic planning. The National Strategic Plan on Climate Change—a.k.a., Intended Nationally Determined Contribution (INDC) of Iran—under the Paris Agreement (PA) accommodates sets of measures to be undertaken in various sectors of the country, including energy and specifically the power generation sub-sector, so as to reduce the emission of greenhouse gases (GHGs). This study begins with a regression analysis of historical data to identify current trends of fossil fuels consumption, wherefrom the emission level of relevant... 

Implementation of telecommunication-based distribution automation is possible in both centralized and decentralized manners. Although centralized automation is more pervasive than decentralized automation, benefits of decentralized automation systems, like improving reliability and speeding up the fault management process, encourage distribution companies to implement these systems. However, high cost of decentralized automation can be a deterrent to most distribution companies. Therefore, economic planning and creating economic justifications for decentralized distribution automation are necessary for the development of these systems. In this dissertation, economic analysis and planning of... 

One of the natural functions of wetlands is to neutralize the dangers caused by floods. Therefore, if a facility is built in the area of wetlands, it should not disturb their natural functioning. During the Iran-Iraq war, several antenna roads were built across the wetland, and the construction of these roads divided the wetland into 5 separate reservoirs. After the end of the war and with the development of the oil fields west of Karun (Hor al-Azim region), the extraction of oil from this region was put on the agenda. With the flood of April 2018, these facilities and roads were exposed to damage and flooding, and oil production from these reservoirs was stopped. In this research, after...
