The paper proposes company's investment activity simulation model; on its basis we investigate the behavior of company's fundamental value under different control parameters. The interaction of bank and corporate borrower's value growth is analyzed. On the basis of regularities obtained a set of decision principles has been formulated determining bank's decision on appropriateness of financial resources...
An equilibrium model of the energy market is extended by a carbon emissions market. In addition, the mix of renewable energy sources is optimized given a limit on total generation. These two new features are integrated into an existing model to assess the effects of a carbon emissions market in a case study of the northern European power system. First, a fixed carbon emissions tax is deployed, revealing...
The internal rate of return of a fuzzy cash flow can be naturally presented as a solution of an algebraic equation with fuzzy coefficients. In this paper we construct fuzzy rate of return using the extension principle. We give an analog of the Norstrom condition providing the existence of a unique internal rate of return. To take into account the interaction of payments, we consider addition of fuzzy...
Supply chain finance is the integration of logistics, fund flow and information flow. Previous researches mostly analyzed the problem of financing decision in a cash-constrained supply chain from the point of financing companies in the supply chain. The paper studies a cash-constrained and two-stage supply chain system including a single manufacturer and a retailer from a new perspective of commercial...
We consider an impact of spreading information about future tax audits on strategies of a population of taxpayers. We suppose that each agent selects the best method of behavior, which depends on the behavior of other agents. Its assumed that all taxpayers pay taxes in accordance with their income, if they know that the probability of an audit is high. Though one share of agents can hide their true...
This paper proposes a mathematical model for a manufacturing and remanufacturing production problem which integrates environmental constraint. This study deals a closedloop system composed by a manufacturing and remanufacturing machines subject to random failures, in order to satisfy the random demand. This paper proposed two mathematical model minimizing the total cost of production, inventory and...
A significant increase in wireless communication has been observed in the last decade. Traditional fixed spectrum allocation presents limitations to better spectrum utilization. Real-time secondary spectrum market seems to be appropriate approach to eliminating the problem of spectrum scarcity. Economic aspects of the new approach are still only partially investigated. Besides the conventional wholesale...
In this paper, an approximate formula for the value of American option with a stock price driven by a geometric fractional Black-Scholes model is derived. A special case of the model would be the model driven by the standard Brownian motion.
Non-standard warehouse receipt pledge credit is a common and basic service form of supply chain financial products. This paper attempts to realize formalization and visualization description for such products. Petri net is used to model the business process of this service, and a hierarchical business model is built with the idea of modularization. Based on model correctness and performance analysis,...
Risk refers to a set of events that lead to loss but risk from the tax perspective refers to the taxpayers' behaviors that may lead to negligence from the public property by the taxpayers due to tax evasion. Such actions cause unusual volatilities in the amounts envisaged in the government budgeting. The fiscal and financial transactions outside the scope of the precautionary bound and failure to...
Our understanding of human behavior is limited and consequently lacks a standard formal model of human behavior that could represent relevant behavior in social-ecological systems. In this paper we explore the consequences of alternative behavioral models using a simple dynamic system of agents of harvesting daisies in the well-known Daisyworld model. We explore the consequences of different behavioral...
Improper disposal of unwanted medications can be very costly and harmful to the environment and people's health. To facilitate safe disposal and remove excessive household storage of medicines, this paper proposes an integrated reverse supply chain (RSC) model with a pharmaceutical company, a recycler, retailers, customers and government. We investigates the impact of different categories of unwanted...
Small-scale distributed photovoltaic (PV) generation, in which PV panels are installed on residential customers' rooftops, has been envisaged as an approach to increase renewable energy participation. In this paper, we have presented a method to determine the economic benefits obtained by residential customers who can freely purchase and sell electricity from an open electricity market, when PV panels...
With the passage of time the needs of an organization grow, therefore, the operational work and responsibilities are also grown. That is why there is a need of hiring more employees. Calculating salaries of many employees requires a lot of work and chances of occurring errors also increase. Automatic Payroll Processing System (APPS) simplifies the work by reducing errors and saving the time. In this...
The purpose of this research is to develop a decision support system that can provide an alternative targets and choose one of them becomes the target of the own source revenue in the Regional Government Budget. Alternative targets are based on model calculations the average unit rates are calculated from the average revenue realization and acceptance of the average percentage growth of each source...
EVA, as a performance assessment or evaluation in the enterprise (or departments), is more and more widely used. Right now, EVA is gradually being applied to the field of business valuation. However, the existing EVA evaluation model is obviously insufficient, especially not accurately reflects the impact of the profit and loss forecast for each year of the enterprise value of existence. In this paper,...
For many years, the relevant analyses have indicated problems in the functioning of the Croatian small-sized enterprises sector. It has been marked by recession, changes in legislation, financing problems, poor cash flow, dependence on large and state-owned companies and the low rate of survival. At the same time, the small-sized enterprises sector has been referred to as a generator of economic development,...
As a relatively new research field, the current literature research on supply chain financial risk management mostly focuses on the concept and qualitative description of value. In the aspect of theoretical research, a theory system on supply chain financial risk comprehensive management has not been formed. In the aspect of practical application, scientific quantitative measure model tools and effective...
Business analytics techniques help mine and analyze business/financial data. For instance, a structural support vector machine (SSVM) can be used to perform classification on complex inputs such as the nodes of a graph structure. We connect collaborating companies in the information technology sector in an undirected graph and use an SSVM to predict positive or negative movement in their stock prices...
Tax control is one of the most important tools for the administration of the tax system (fiscal, social, regulatory and control). Tax audit enables to increase the revenue of taxes and fees in the state budget. Assume that each taxpayer can declare his income less then his true income level, however total tax audits of the taxpayers' population is economically unreasonable and even selective tax audits...
