Development of the pavement network systems, which is inevitable due to rapid economic growth, has increasingly become a topic significant concern because severe environmental impacts road expansion. For achieving sustainable development goals (SDGs), policies and actions towards pavements’ life cycle assessment (LCA) cost analysis (LCCA) must be carefully assessed. Consequently, purpose this r...

An integrated life-cycle assessment and life-cycle cost analysis model was developed and applied to enhance the sustainability of concrete bridge infrastructure. The objective of this model is to compare alternative bridge deck designs from a sustainability perspective that accounts for total life-cycle costs including agency, user, and environmental costs. A conventional concrete bridge deck a...

Vehicle coating is an important component of automotive manufacturing. The paint shop constitutes the plurality of initial investment in an automotive assembly plant, consumes the majority of energy used in the plant’s operation, and generates significant waste from paint overspray. The coating process also results in the emission of polluting volatile organic compounds (VOCs). New paint techno...

introduction: food industry is one of the most important industries in developing countries that has an enormous role in employment, export and value added of the agricultural sector. iran as a developing country has a comparative advantage in food product industries for several reasons such as adequate and cheap raw materials and having several companies in the field of food industries. the fo...

a new mathematical model for the optimal production isformulated for the inventory management system under time-varyingand stochastic inflation environment for deteriorating items. the timehorizon is finite and demand rate is dependent to the inflation. in thereal situation, some but not all customers will wait for backlogged itemsduring a shortage period, such as for fashionable commodities or...

Inventory models in which the demand rate dependents on the stock- dependent are based on the common real- life observation that greater product availability tends to stimulate more sales. In this study we develop an inventory model to determine an optimal ordering policy for quantity dependent demand rate and time dependent holding cost items with delay in payments permitted by the supplier un...

In recent decades, excessive using fossil fuels has been resulted in emitting greenhouse gases such as CO2, consequently, environmental pollution. In this study, the techno-economic analysis of the CCHP/PV hybrid system application for a sample building was examined to reduce the environmental pollution and primary energy consumption of the buildings. The life-cycle cost analysis was...

Air-Conditioning (AC) systems are responsible for a considerable portion of the energy consumption in buildings located in high cooling load requiring regions of Iran. In addition, the heat flow through the buildingschr('39') external walls plays a major role in cooling load estimations for the countrychr('39')s hot regions. Therefore, application of insulation materials in external walls has g...
