Aircraft Boarding Strategies
The pandemic caused by the COVID-19 virus (SARS-CoV-2) has been a source of concern for airlines regarding safe flight environments. The main reason is that infected people may experience no symptoms. Nevertheless, they may have high viral loads and spread the disease. To ensure the safety of passengers concerning virus propagation, such as COVID-19, and keep the turnaround time at low levels, airlines should seek efficient aircraft boarding strategies in terms of both physical distancing and boarding times.

BSC-Based Digital Transformation Strategy Selection and Sensitivity Analysis
The digital transformation era is ushering in a revolution in how businesses operate, communicate, and compete. This seismic shift is driven by technological advancements, changing customer expectations, and the need for greater efficiency and agility. In 1992, David Norton and Robert Kaplan introduced the Balanced Scorecard (BSC) as a component of a strategic project management framework. The Kaplan–Norton BSC model emphasizes four well-rounded perspectives: financial, customer, internal business processes, and learning and growth.

Concentrated Solar Power Technology
The modernization, efficiency, and decarbonization of the energy supply systems are among the new challenges to be faced in the coming decades to achieve the targets and objectives dictated by European strategic policies. Despite the countless benefits related to renewable energy sources (RES) integration, this brings key challenges to the power system, such as the risk of imbalance between energy generation and demand, sudden changes in flows in transmission lines with a need for expensive and time-consuming upgrades, and the withdrawal of conventional generation systems with consequent demands for new solutions and innovation to support grid services. A potential solution to limit the huge intermittence and fluctuation in power generation from RES is Concentrated Solar Power (CSP) technology integrated with thermal energy storage.

Operation Optimization of Complex Industrial Processes
The operation optimization of complex industrial processes is a dynamic multi-objective optimization problem. These problems cover industrial areas such as steel, chemicals, and energy. Specifically, they address operation optimization problems under uncertain environments in production processes, with production metrics as the optimization objectives and controllable variables as the decision variables. They consider changing factors in production processes, operational metrics, and constraints on production metrics, establishing dynamic models for solving these problems. Unlike static models, these objectives and constraints change over time, similar to how the Pareto set (PS) and Pareto front (PF) in dynamic multi-objective optimization problems (DMOPs) can change over time.

To Solve Scheduling Problems to Minimize Carbon Footprint
Effective scheduling is an important method proposed by some shop floor engineers and operational analysts to minimize carbon emissions. Scheduling always has a key role in the manufacturing environment and operations management. There is a direct link between the energy consumption of a manufacturing facility and its environmental impact, which is mostly analyzed as a carbon footprint.

Humanitarian Supply Chains
In humanitarian logistics, efficiently evacuating people during disasters poses a significant challenge. Comprehensive plans are essential for moving individuals from affected areas, encompassing both pre- and post-disaster phases. These plans must optimize resource usage, including public transportation, and consider those with mobility challenges.

Robot Target Recognition and Grasping Pose Estimation
The deployment of collaborative robots on a large scale in intelligent factories has increased with the convenience of human–robot collaboration to replace manual labor in undertaking 3C (Computer, Communication, and Consumer Electronics) manufacturing and intelligent handling. As a result, the intelligence, speed, and reliability of these robots have become core factors that impact the productivity and production quality of intelligent factories. Objectively sorting objects is a vital and habitual responsibility in intelligent production lines featuring collaborative robots.
