Dear Colleagues,

The present Special Section aims to collect the most recent and notable studies of the theory and application of the intelligent algorithms in decision modelling taking into account the uncertainty in the environment.

This cutting-edge field integrates advanced technologies, such as artificial intelligence, data analytics, numerical and optimization methods for large-scale problems into industrial processes, revolutionizing the way industries operate. The growing challenges and complexity of business the environment created difficulties in making management decisions related to the inability to efficiently and effectively predict the business results of economic processes. An environment with a high intensity of changes determining decisions, taken in uncertain situations caused by unpredictability in the behavior of competition, political instability, inflation and demographic collapse, uncertainty at the local, regional and global level. Management faces inaccurate limitations due to inability to sense and detect continuous changes in the influence of environmental factors. Management in the business environment with many instability and unreliability. Managers get into stressful situations, take decisions at risk, with scarce and inaccurate information, even forced by constant changing circumstances to decide even in conditions of absence of information. The idea is to stimulate the development of modern alternatives for optimal and efficient business management in an uncertain business environment.

The topics of interest include, but are not limited to:

• Intuitionistic fuzzy logic and its extensions in decision-making problems

• Statistical analysis in uncertain environment
• Optimization in uncertain environment
• Computational algorithms for large-scale problems
