Description:

Fuzzy Cognitive Maps (FCM) are widely applied to support decision making and for the prediction of the future behavior of systems. In this paper several real expert-defined models of an organization will be investigated. Simulations were performed in order to examine the asymptotic behavior of these models, especially to find (all) fixed point attractors, or to discover chaotic behavior. A sigmoid type of inference function was applied, and the effect of the steepness parameter on simulation results was investigated, too. It will be shown by several examples that the steepness parameter may even change the number and values of the final state vectors. In the end, the systematic study of the behavior of the models in terms of the changes of the (uncertain) relationship values among system components were studied.

A novel diversity induction method for bacterial memetic algorithm by hibernation of individuals

János Botzheim

Publication Name: Proceedings 2012 6th International Conference on Genetic and Evolutionary Computing Icgec 2012

Publication Date: 2012-12-01

Volume: Unknown

Issue: Unknown

Page Range: 328-331

Description:

Memetic algorithms combine evolutionary algorithms with local search heuristics in order to speed up the evolutionary process. The bacterial memetic algorithm applies the bacterial operators instead of the genetic algorithm's crossover and mutation operator. In this paper a novel diversity induction method is proposed for bacterial memetic algorithm. Hibernation of some individuals in the population is applied for avoiding premature convergence to local optima. This operation can help in turning back from unpromising region of the search space by previously found solutions represented in hibernated bacteria. © 2012 IEEE.

Comparison of discrete- and continuous-time models for scheduling waste wood processing facilities

Máté Hegyháti Balazs David Olivér Osz

Publication Name: Central European Journal of Operations Research

Publication Date: 2023-09-01

Volume: 31

Issue: 3

Page Range: 853-871

Description:

With the growing significance of environmental awareness, the role of renewable materials and their reuse and recycling possibilities have become increasingly important. Wood is one of the best examples for this, as it is a material that has a variety of primary uses, while also being a prime candidate for reuse and recycling. An important phase in most waste wood value chains is the processing of bulk waste from various sources, usually by means of shredding. This paper presents methods for scheduling the machines in such a waste wood processing facility, where incoming deliveries of different types of wood are processed by a series of treatment and transformation steps to produce shredded wood. Two mathematical models are developed for the problem that both allow overlaps between consecutive steps to optimize resource flow through the system. One of these is a more traditional discrete-time model, while the other is precedence-based and uses continuous-time variables for the timing of the various tasks. Both modeling techniques have their advantages and shortcomings with regard to the ease of integration of further problem-specific parameters and requirements. Next to providing a sound approach for the identified problem class, another aim is to evaluate, which technique suits better for this problem class, and should be used as a basis for extended and integrated cases in the future. Thus, the performance of these models is compared on instances that were randomly generated based on real-world distributions from the literature.

An implicit Method of Fundamental Solutions using twofold domains

Csaba Gáspár

Publication Name: Engineering Analysis with Boundary Elements

Publication Date: 2017-09-01

Volume: 82

Issue: Unknown

Page Range: 194-201

Description:

A novel meshless method is presented. It is based on completing the original problem with an additional one which is defined in the same domain and connected with the original problem through the boundary only. The boundary conditions are enforced by some internal sources appearing in the supplementary problem only. The fundamental solutions are not used explicitly. The two problems are solved simultaneously using computationally quite efficient multi-level tools. No dense and ill-conditioned linear systems have to be solved. Moreover, no external or boundary sources are to be located. The approach can easily be extended to more general elliptic problems in a natural way, since the corresponding fundamental solution is not needed to be known.

Description:

With the recognition that the engineering structures maintenance and repair needs far exceed the rescourses available to adress these needs, many firms have to turned to the development of ESMS (Enginnering Structures Management System) as a method to improve the allocation of these limited resources and the condition of their engineering structures. The paper provides an overviev of the need for ESMS.

INDUSTRY 5.0 AS A HUMAN-CENTRIC DIRECTION FOR SOCIAL AND LABOR ENTITIES TRANSFORMATIONS

Leonid Melnyk Oleksandr Kubatko Lyudmila Kalinichenko Sándor Remsei

Publication Name: Problems and Perspectives in Management

Publication Date: 2025-01-01

Volume: 23

Issue: 4

Page Range: 290-300

Description:

The interaction of humans with artificial intelligence and cyber-physical systems opens the way to understanding the role of humans in modern industrial ecosystems. The research purpose is to examine the roles and functions of humans in implementing Industry 5.0 through the analysis of personality transformations in social and labor entities. A structured review methodology that synthesizes existing research on Industry 5.0 as a human-centric direction using systematic and transparent procedures (framing the question, identifying relevant publications in the Scopus database, summarizing the evidence, and interpreting the findings) is used. Within Industry 5.0, the physiological needs of a bio-human (needs for food, water, living conditions, etc.) and the technocratic interests of a labor-human (the desire to earn money, career growth, prestige, etc.) are overwhelmed in terms of time and effort by the socio-human personality needs (intellectual development, the realization of creative abilities, and obtaining knowledge). In complex technical tasks and strategic decision-making processes, humans continue to play a key role, emphasizing that full automation is not possible in all areas, and a human-centric approach remains the basis of production systems. Among the key personality skills needed for Industry 5.0 are analytical and creative thinking, the ability to design technology, critical thinking, ability to solve complex problems, leadership skills, emotional intelligence, and generating new ideas. Industry 5.0 promotes the consumption of mainly information and services dictated by the informational (spiritual) nature of the personality and relatively depresses the use of materials and services, dictated by the material nature of the human-bio.

Green Energy–Related Financial Literacy for Environmentally Sustainable Development

Csongor Czipf Absalón J. Salmerón- Zapata José G. Vargas- Hernandez

Publication Name: Materials Techniques and Ecological Impact of Sustainable Prototyping

Publication Date: 2026-01-01

Volume: Unknown

Issue: Unknown

Page Range: 269-300

Description:

In the framework of ecologically sustainable development, this research paper explores the crucial relationship between financial literacy and the use of green energy. The study looks into how institutional and individual financial knowledge affects choices about energy-efficient technology, sustainable financial products, and investments in renewable energy. This paper highlights important gaps in green energy financial literacy that impede the shift to sustainable energy systems by thoroughly analyzing the body of existing literature, actual data, and theoretical frameworks. The study uses a mixed-methods approach, combining qualitative interviews with policymakers and industry professionals with quantitative surveys of 2,500 respondents from a range of demographic categories. Important findings show that although 78% of respondents are generally aware of the advantages of green energy, only 32% of them are sufficiently knowledgeable about green investments, tax breaks, financing options, and long-term cost-benefit evaluations.
