One method of isolating the useful signal from the noise is by using a soft- processor Kalman filter. There are many applications of how one could use a Kalman filter: using navigation systems, such as satellite or radio, and sonar tracking systems. The guidance systems in military applications...

The explanation of investment behaviour in the light of expected utility it meant an important step in the substantiation of the theory regarding investment portofolio. It was demonstrated that the linear form of utility function excludes certain decisive decisions (Allais’s paradox), so that...

The approach to decision theory has varied from one scholar and school of thought to the other from the development of mathematically complex systems, models and equations to the disregard of this particular academic endeavor altogether due to randomness and overwhelming subjectivity and...

The Modified Han (MH) algorithm aims at providing a cost optimized solution to real world maritime container transportation problems, which often are unbalanced and inconsistent. By modelling a 3-index container transportation problem as an inconsistent systems of linear inequalities, we apply...

Dynamic Programming is a general algorithm design technique for solving problems defined by or formulated as recurrences with overlapping sub-instances. Dynamic programming is regarded as a particular approach to optimization problems in which a considerable number of decision variables and the...

The firms have different behaviors on the real market. Starting from these ideas the present paper intends to identify the main explanatory elements that show the evolution of the firm. We study the effect of time delays in evolutionary games with one population of users and two strategies. The...

The distributed databases are fundamental elements of the informatics systems contained in the infrastructure of an economic organization with offices distributed in various locations around the world. This paper presents the techniques by which a distributed database management system provides...

In our paper, an approach is proposed for determination of equilibrium solutions for several ports operators who are competing among themselves for cargo, i.e. under oligopoly. This approach is a combination of the methods from microeconomics and operations research (non-linear transportation...
