The transition within transportation towards battery electric vehicles can lead to a more sustainable future. To account for the development goal ‘climate action’ stated by United Nations, it is mandatory, conceptual design phase, derive energy-efficient system designs. One barrier uncertainty of driving behaviour usage phase. This often addressed using stochastic synthesis process representati...

Microalgae harvesting by coagulation can use coagulant agents such as alum, synthetic polymers or biocoagulants. Biocoagulants have attracted the attention of researchers because they are natural, biodegradable, and promote high microalgal efficiencies. This study aims to optimize Chlorella vulgaris based on dosage Opuntia cochenillifera extract choice eluent for biopolymer extraction. The outd...

For assessing and selecting sustainable suppliers, this study considers a triple-bottom-line approach, including profit, people and planet, and regards business operations, environmental effects along with social responsibilities of the suppliers. Diverse metrics are acquainted with measure execution in these three issues. This study builds up a new hybrid intelligent model, namely COA-LS-SVM, ...

This paper presents a solution on the optimization of traffic lights cycle depending on the timeframe by developing a mathematical model. Based on the analysis and processing of data obtained from a traffic lights intersection with intense traffic in Sibiu, was developed a mathematical model that allows an algorithmic approach to programming sequences for ensuring a smooth traffic. The article ...

We propose a hybrid evolutionary algorithm based on discrete Particle Swarm Optimization for solving a novel remanufacturing sustainable supply chain design problem. There is little research being done in mathematical modeling and solutions methods for these problems. The paper describes a NP-hard mixed-integer 0-1 model (MIP) for this remanufacturing sustainable problem in which given a networ...
