This paper is about finding a solution to a transport problem, using visual programming applications, with one of the specialty software – Visual Basic. Among company’s spendings there are product transport spendings suported by economic agent in his way from each producers to beneficiaries....

In quantitative approach to decision making, a possible point of view for portfolio optimization is to model a portfolio in terms of a linear program. In this approach a linear programming model is in form of continuous non-negative variables instead of integer non-negative variables. In some...

The EU statistics reveal over 19 million active enterprises within the EU-27’s nonfinancial business economy (defined as industry construction, distributive trades and services, and therefore excluding financial and public services) in 2004. About one third (32.5%) were active in the...

A Really GENERAL Decomposition Algorithm for Very Large Linear Optimization Problems Proven theory as Regards Optimality and Finality Advantageous for very large problems with a rather small percentage of real variables in the optimal solution - Simplex method is used as a calculating...

In this paper, we examine main properties of the Constant Proportion Portfolio Insurance (CPPI) strategy, when trading in continuous-time is not allowed. We focus instead on stochastic-time rebalancing. We prove that investor's tolerance determines crucially portfolio performance, in particular...

The Ramsey model of economic growth is revisited from the perspective of viability theory. The Ramsey model, augmented with minimal consumption and sustainability criteria, becomes a viability problem. The framework allows for a clear picture of optimal viable, optimal nonviable, and viable...

In this paper a type of Heath, Jarrow and Morton (1992) (HJM) based affine model is derived theoretically. This type of affine model is obtained by applying Linear Realization Theory to construct Finite Dimensional Realizations (FDRs) of the Gaussian HJM model. The algorithms of constructing...

We derive a general equilibrium linear relationship between the market prices of risks and market risk aversion under a continuous time stochastic volatility model completed by liquidly traded options. The relation is robust as it is valid for both endowment and production economies, and for...

Why do some men father children outside of marriage but not provide support? Why are some single women willing to have children outside of marriage when they receive little or no support from unmarried fathers? Why is this behavior especially common among blacks? To shed light on these...

The Cumulative Prospect Theory (CPT) is one of the most popular theories for evaluating the behavior of decision makers in the context of risk and uncertainty. This theory emerged as a generalization of the Expected Utility Theory (EUT) and being a relatively recent theory, its application has...
