Abstract We present a multi‐objective optimization framework for the design of an algal biorefinery with multiple target products. Four environmental endpoint indicators and economic performance are used as objective functions following life cycle assessment (LCA) methodology. The process alternatives modeled superstructure covering total 720 feasible routes. proposed method optimizes not only ...

the dynamic nature of projects and the fact that they are carried out in changing environments, justify the need for their periodic monitoring and control. collection of information about the performance of projects at control points costs money. the corrective actions that may need to be taken to bring the project in line with the plan also costs money. on the other hand, penalties are usually...

Hybrid electrical energy storage (HEES) systems consisting of heterogeneous electrical energy storage (EES) elements are proposed to exploit the strengths of different EES elements and hide their weaknesses for achieving a combination of superior performance metrics. The cycle life of the EES elements is one of the most important metrics that should be considered carefully. The cycle life is di...

This study suggests an optimization method for the life cycle cost (LCC) in an economic feasibility analysis when applying energy saving techniques in the early design stage of a building. Literature and previous studies were reviewed to select appropriate optimization and LCC analysis techniques. The energy simulation (Energy Plus) and computational program (MATLAB) were linked to provide an a...

Sustainability legislation, new consumer behaviour and the complexity of global trade are increasingly changing the way of designing and managing supply chains. In this context, one should take into consideration sustainability factors, such as minimization of carbon emission, treatment of reverse flows, optimization of energy consumption; etc., simultaneously with the product’s life cycle desi...

In the present study, the aim is to optimize full and half toroidal continuously variable transmission (CVT) in order to minimize the vehicle fuel consumption (FC) in ECE driving cycle. First, the model of both CVTs’ efficiency is presented. The control strategy of CVTs speed ratio based on minimizing the vehicle FC is introduced, and the algorithm of calculating the vehicle FC is shown. Afterw...

Optimization models can support decision-makers in the synthesis and operation of multi-sector energy systems. To identify optimal design a low-carbon system, we need to consider high temporal spatial variability electricity supply, sector coupling, environmental impacts over whole life cycle. Incorporating such aspects optimization is demanding. avoid redundant research efforts enhance transpa...
