many real water resources optimization problems involve conflicting objectives. in this study, multiobjective genetic algorithm nsga-ii, has been developed for optimization the conjunctive use of surface water and groundwater resources and optimal management of supply and demand of agricultural water. here, optimal allocation of land and water resources to the dominant products in najaf abad pl...

The safe operation of a semi-batch catalytic reactor remains a sensitive issue when highly exothermic side reactions may occur, and various elements such as controllability, stability, safety, and economic aspects have to be considered in the process development. Nominal operating conditions are set to avoid excessive thermal sensitivity to variations in the process parameters. Several shortcut...

cash is a critical source for business enterprises and creating balance between available cash and the required cash is the most important factor concerning the economic viability of a business enterprise. both of the companies that do not hold enough cash or hold too much cash, face too much problems. this paper investigates the impact of deviation from the estimated optimal cash level on firm...

In this paper we study a continuous time, optimal stochastic investment problem under limited resources in a market with N firms. The investment processes are subject to a time-dependent stochastic constraint. Rather than using a dynamic programming approach, we exploit the concavity of the profit functional to derive some necessary and sufficient first order conditions for the corresponding So...

Solvent–steam mixture is a key factor in controlling the economic efficiency of the solvent-aided thermal injection process for producing bitumen in a highly viscous oil sands reservoir. This paper depicts a strategy to quickly provide trade-off operating conditions of the Expanding Solvent–Steam Assisted Gravity Drainage (ES-SAGD) process based on Pareto-optimality. Response surface models are...

A building integrated photovoltaic thermal (BIPVT) system is a complex technology that produces electricity and heat simultaneously. The media in BIPVT only uses heated air as an energy source for heating cooling without other facilities such fans, which facilitates the construction process reduces damages to due freezing or leakage. use of handling unit (AHU) connected air-type collector load ...
