Abstract:

Use of artificial intelligence systems in forecasting financial markets requires a reliable and simple model that would ensure profitable growth. The model presented in the paper combines Evolino recurrent neural networks with orthogonal data inputs and the Delphi expert evaluation method for its investment portfolio decision making process. A statistical study demonstrates the reliability of the model and describes its accuracy. Capabilities of the model are demonstrated using a trading simulation.

Abstract:

The paper suggests the author's method of analyzing the investment climate and assessing unsystematic investment risk. The authors propose an original non-traditional approach to the solution of two interrelated problems: investment climate diagnostics and investment risk level evaluation. The technique can be applied by both an investor for making an investment decision and an issuer for analyzing reasons of the low investment object attractiveness. It makes it possible to identify the barrier and restrictive factors determining a high risks and to develop measures to reduce them. The advance

Abstract:

Investors and decision makers (DMs) have become increasingly interested in portfolio selection in a borderless world in recent years. In real-world market situations, the performance of a great number of portfolios is typically unpredictable due to the presence of uncertainty and unreliable factors in numerous criteria. Therefore, it is essential to increase investor returns and promote an investment strategy through thorough evaluation. This occurrence becomes critical if the DMs employ an unsuitable strategy that fails to handle both aspects in a prudent manner. Due to its importance, this p

Designing maintenance strategies for a vast portfolio of aging infrastructures requires decision-makers to ensure adequate safety levels while addressing the requirements on service interruptions, costs, and workforce availability. This study addresses the problem of scheduling maintenance interventions for a portfolio of bridges, aiming to minimize CO2 emissions while meeting minimum reliability requirements and adhering to workforce and budget constraints. To achieve this, we present a Simheuristic algorithm that combines a metaheuristic core based on the Adaptive Large Neighborhood Search m

This article discusses the penetration of communication technologies in communication and social behavior patterns of rural and urban communities. The Internet was not able to erode the sense of nationalism and replace it with global values. This study also illustrates the effective communication with family, neighbors, or friends through social media in both urban and rural. An analysis shows that the internet does not affect prosocial attitudes, in traditional, moderate, and modern societies in urban and rural communities.

Abstract:

AbstractCrypto assets have become increasingly popular in recent years due to their many advantages, such as low transaction costs and investment opportunities. The performance of crypto exchanges is an essential factor in developing crypto assets. Therefore, it is necessary to take adequate measures regarding the reliability, speed, user-friendliness, regulation, and supervision of crypto exchanges. However, each measure to be taken creates extra costs for businesses. Studies are needed to determine the factors that most affect the performance of crypto exchanges. This study develops an integ
