This paper proposes a Fuzzy Goal Programming model (FGP) for a real aggregate production-planning problem. To do so, an application was made in a Brazilian Sugar and Ethanol Milling Company. The FGP Model depicts the comprehensive production process of sugar, ethanol, molasses and derivatives,...

This paper examines the optimal control of CO2 emissions from a perspective of efficiency analysis. Several centralized data envelopment analysis (DEA) models are introduced to study the optimal allocation of CO2 emissions under spatial, temporal and spatial–temporal allocation strategies,...

Canadian oil sands hold the third largest recognized oil deposit in the world. While the rapidly expanding oil sands industry in western Canada has driven economic growth, the extraction of the oil comes at a significant environmental cost. It is believed that the government policies have failed...

Policy makers in a number of countries have proposed or are considering proposing CO2 emission standards for new fossil fuel-fired power plants. The proposed standards require coal-fired power plants to have approximately the same carbon emissions as an uncontrolled natural gas-fired power...

This paper examines the potential welfare effects of storage under different market structures. This includes combinations of perfectly competitive and strategic generation and storage sectors, and standalone and generator-owned storage. We demonstrate that if the generation sector is perfectly...

China is the world's largest CO2 producer and energy consumer. In this paper, we calculate the maximum technically obtainable CO2 emissions reduction from the efficient use of inputs and estimate the shadow prices of CO2 emissions in order to assess the potential cost savings deriving from...

U.S. ethanol policies have contributed to changes in the levels and the volatilities of revenues and costs facing ethanol firms. The implications of these policies for optimal investment behavior are investigated through an extension of the real options framework that allows for the...

This paper proposes a dynamic programming model to explore the optimal stockpiling path for China's strategic petroleum reserve before 2020. The optimal oil acquisition sizes in 2008–2020 under different scenarios are estimated. The effects of oil price, risks and elasticity value on inventory...

The import risks confronting oil consumers are influenced by transport conditions, oil prices, geopolitics, etc. This paper constructs an evaluation framework for oil import security from a perspective of supply chain process, and builds a two-phase DEA-like model to evaluate oil import...

This paper presents an approach for calculating a tariff for electrical energy distribution systems. The methodology is similar to the standard tariff-calculation method used in Brazil. The approach combines the concepts of time-of-use tariffs and Ramsey prices. The process, initially designed...
