This paper examines the problem of choice investment strategies of firms in an oligopoly markets. We study the impact of investment strategies of companies on its financial performance and the efficiency of investment under demand uncertainty and competition in the market. A mathematical model describing the investment behavior of firms in an oligopoly markets presented. A solution of the problem...
The increasing amount of gathered sensor data in Industry 4.0 allows comprehensive data analysis software that creates value-adding opportunities. As companies often cannot implement such software by themselves and as they typically don't want to give their data to external scientists, they commission them to build the required software in order to execute it locally. However, installing, configuring,...
Globalizing changes in society are able to influence changes in the economies of individual countries. Individual economic entities from various sectors attempt to achieve high economic performance and development. They do this within the conditions that are possible at that time; if there are favorable conditions for their development, this will result in creating innovative production and its subsequent...
There are different studies analyzing which are the aspects influencing the project success; this paper will focus on the project knowledge management and the sustainability in project management. As it is broadly accepted that these two fields impact directly on project success. There has been studied separately but in this case, there is going to analyze the combination of each of them. The model...
Social capital is transformed due to the digitalized environment built with the ICT expansion. The evolution of the social capital' forming and development reflects the new forms and models of communication, the extended possibilities of choice and of presence into the Web as a unique space of exchange. This article presents the theoretical approach to the analysis of behavior' regulation within the...
The article is devoted to the problem of making environmental management decisions that take into account the interests of the enterprise in the form of profit and the interests of society and the state, by reducing damage to the environment. The authors pay attention to the process of making environmental management decisions. Proposed algorithm for making environmental management decisions is presented...
In the pharmaceutical supply chain, all players have to ensure the highest level of service while containing costs, because of the ethical issues concerning drugs. The outsourcing of logistics should be recognized as a competitive lever, especially in this complex and highly regulated industry. Based on these premises, the research objective of this study is to investigate the relationship between...
The Maximum Diversity (MD) problem is the process of selecting a subset of elements where the diversity among selected elements is maximized. Several diversity measures were already studied in the literature, optimizing the problem considered in a pure mono-objective approach. This work presents for the first time multi-objective approaches for the MD problem, considering the simultaneous optimization...
In the current Brazilian energy sector a lack of management for connecting distributed generation sources in distribution networks, especially mini and micro generation, can lead to several negative impacts on the quality of electrical energy supplied to the customers. The distribution energy companies are responsible for controlling and managing the distribution network in order to maintain the quality...
Nowadays complex and dynamic business environments require easy and hands-on methods for enterprise modelling that recalibrate models constantly. This article describes a set of tools and techniques for enriching organizational models with semantic information and adjusting them on request. Firstly, we propose an approach for binding the model with relevant documents and experts. Secondly, we define...
Although that Cloud infrastructures are nowadays available, there is a lack ofadoption by companies. While big companies with large computing devisionsadopted the Cloud paradigm, small and midsize enterprises (SME) with a limitednumber of computer experts were scared by the complexity of the technology and by the huge investement to move to Cloud. But even for SMEs, the migration to Cloud infrastructure...
Impact Financing funding models, namely Social Impact Bond and Impact Investing, are applied worldwide. However, they do not receive enough attention in the Czech Republic. The present study analyzes closely these methods, describes their functional principles and practices and illustrates them with process maps. Importantly, it is contextualized within the Czech conditions. The study includes an...
The electric utility depends on accurate load predictions for scheduling spinning reserve, unit commitment, fuel allocation and maintenance. Artificial neural networks (ANNs) have been the popular method for load forecasting but support vector machines (SVM) have recently been successfully applied to the challenge of load forecasting. In this study, the ANN and SVM techniques were applied to short...
A federated cloud environment is composed of interconnected clouds that share resources using an interface, transparent to users. In such environments, ensuring security is a complex task, since individual characteristics of each federated cloud has to be considered. This is one important issue, which can prevent companies and organizations from adopting federated clouds. In this context, this paper...
The study of mechanisms to faciliate the economic development of social groups is of vital importance to social scientists. One of the major contributions to development is the creation of economic clusters that are used together to achieve specific objectives. This consists of identifying business groups, companies, or muncipalities that are spacely disseminated. In this research, we propose a methodolgy,...
The internet changed the traditional ways of relationship between and the consumers. The company started offering new buying, selling and shipment models to their customers. On a Portuguese context the most seller sector is the holydays and accommodations with 55% of online sales. Through the time evolution new models where investigated to study the service quality, to provide a higher service quality...
Coopetition (cooperation between competitive organizations) was conceptually established several years ago. However, the number and diversity of business model elements (products, partners, employees, customers, processes) within and outside particular supply chains has grown, establishing a need for rethinking relationships between stakeholders with similar and yet also competing strategies. Second,...
In order to reduce the complexity of modeling product lines, many authors propose modeling product concerns separately by using multiple feature models. These proposals use well-known operations such as merge, union and slice to compose the models for analysis and engineering. Such operations produce new models that represent sets of products that comply with the semantics of the operations. We use...
In recent years, several countries have placed strong emphasis on openness, especially open data, which can be shared and further processed into various applications. Based on studies, the majority of open data providers are government organizations. This study presents two cases in which the data providers are companies. The cases are analyzed using a framework for open data based business models...
In the article the game-theoretic model of limited resource extraction by competitive enterprises in terms of differential non-zero sum games is considered. The Nash equilibrium is found and the cooperative variant of the game investigated, the Shapley value constructed and its dynamic stability (time-consistency) investigated. As the results of this work were found the conditions on the input parameters...
