After 1990, the Romanian health system has entered into a comprehensive reform process, which continues even today in order to meet the conditions imposed by the European Union. Also, the implementation of a risk management's system in each hospital is a condition that has to be accomplished and implemented. As the risks encountered at a hospital's...

The present paper focuses on the development of a computational grey model designed of such a manner that will allow to firm's managers a better picture about the risks their firm can be exposed to in the future. For this, elements taken from grey systems theory are taken into account for melting the firms' characteristics and for establishing the...

The main objective of the paper is to discuss how indicators and metrics can be used in risk management. In introduction, there are presented some general ideas about enterprise risk management and its implementation using key risk indicators (KRIs). In Section, there are presented several definitions for KRI and the steps which must be followed fo...

Purpose The present paper focuses on the major risk categories that could be encountered in hospitals and other medical facilities and attempts to determine which are more important from the patients’ perspective for the purpose of improving to the hospital-patient relationship improvement.

Recent studies have shown that based on informal communication, made from one user to another, certain opinions regarding the activity of a company can be formed, with long-term influence on consumers, perception on its image. By focusing on the Millennial generation, this research presents its main characteristics and examines the consumer’s behav...

This paper aims to model the covariance of financial assets using neutrosophic fuzzy numbers. Two main concepts are discussed and used, namely the neutrosophic covariance of the financial assets and the independent neutrosophic portfolios. In terms of methodology, a three-step approach is proposed with the purpose of identifying the independent neu...

The purpose of this paper was to model, with the help of neutrosophic fuzzy numbers, the optimal financial asset portfolios, offering additional information to those investing in the capital market. The optimal neutrosophic portfolios are those categories of portfolios consisting of two or more financial assets, modeled using neutrosophic triangula...

As the evacuation problem has attracted and continues to attract a series of researchers due to its high importance both for saving human lives and for reducing the material losses in such situations, the present paper analyses whether the evacuation doors configuration in the case of classrooms and lecture halls matters in reducing the evacuation...

This paper studies the problem of tangible assets acquisition within the company by proposing a new hybrid model that uses linear programming and fuzzy numbers. Regarding linear programming, two methods were implemented in the model, namely: the graphical method and the primal simplex algorithm. This hybrid model is proposed for solving investment...

This paper focuses on the environmental conflicts induced by insufficient continuous snow cover on the ski areas in Romania. The case study aims envisions the area of Southern Carpathians, Latoriței Mountains, belonging to the group of Parâng Mountains. The area chosen to develop and improve the artificial snow system was conducted for in the propo...

This paper studies the problem of neutrosophic portfolios of financial assets as part of the modern portfolio theory. Neutrosophic portfolios comprise those categories of portfolios made up of financial assets for which the neutrosophic return, risk and covariance can be determined and which provide concomitant information regarding the probability...

This research sets the basis for modeling the performance indicators of financial assets using triangular neutrosophic fuzzy numbers. This type of number allows for the modeling of financial assets performance indicators by taking into consideration all the possible scenarios of their achievement. The key performance indicators (KPIs) modeled with...

The paper aims to develop a MAMDANI fuzzy controller for detecting the financial sustainability risk of the assets owned by the company. This type of risk indicates when an asset no longer produces economic benefits to the company, or the benefits are small enough to no longer justify the asset maintaining in working order. The proposed fuzzy contr...

This paper develops a Mamdani fuzzy logic system (FLS) that has stochastic fuzzy input variables designed to identify cash-flow deficits in bank lending policies. These deficits do not cover the available cash-flow (CFA) resulting from the company's operating activity. Thus, due to these deficits, solutions must be identified to avoid companies' fi...

As companies operate in a competitive environment, where the struggle for survival on the market is rather tough, the top management face new challenges to identify methods, and even techniques, which allows it to select from the market those assets that provide an optimal ratio between the acquisition cost and the economic performance. In this con...

Sentiment analysis is one of the most important topics in the Natural Language Processing field, aiming to determine whether a text expresses a positive, negative or neutral perception. In most sentiment analysis applications, a central role is played by the sentiment lexicons, which are lexical resources that include lists of tokens, together with...

Purpose The purpose of this paper is to focus on the adjustment of the GM(1, 2) errors for financial data series that measures changes in the public sector financial indicators, taking into account that the errors in grey models remain a key problem in reconstructing the original data series. Design/methodology/approach Adjusting the errors in gre...

Through this study we intend to demonstrate that the capital market index in Romania is influenced by the real GDP, the stock exchange indices, the real interest rate, the exchange rate RON/USD and the inflation rate. Therefore, the grey systems theory has been used, namely the degrees of grey incidences have been calculated for the considered vari...

Due to the development of information technology, every enterprise has a lot of data, which magnify the difficulties of selecting the most relevant. Hence, appears the mistake of measuring too many things. Owning too much information, will lead to vagueness, the opposite effect of a measuring system. This phenomenon does not depend on the manager’s...

Today, the beneficai impact of using Key Risk Indicators (KRI) is known all over the world, but there isn't a structured and uniform approach to build and apply KRI in every „ structure" of a company. In this paper, six of the most KRI have been identified along with their underlying correlated indicators. Implementation of KRI is necessary for obt...
