In this paper I want to present the results obtained by using an algorithm in calculating locations for regional hospitals that could be built in Romania. The idea of regional hospitals in Romania have been discussed for some time in the local press, the final locations being established, by those responsible, in the first 8 cities, taken according to the number of inhabitants, as well as a city in the center of the country. In this approach we use a genetic algorithm, a method inspired by natural evolution, which will give us a series of alternative results to the solution proposed by officials. As in the official version, in the used method, to obtain the results we will take into account the population, but not only within the most populated localities, but within a larger number of localities from the country. The population of these localities, weighted with the distance between them and the possible solutions will contribute to the calculation of the final solution. [ABSTRACT FROM AUTHOR]

In this paper, we will discuss how to choose heating units using the utility function. This paper is conceived as a detailed continuation of the analysis made by the authors in their doctoral thesis. This paper is among the first tries of this type from Romania. A case study shows the practical application of this algorithm, and the results obtained were compared to the results obtained by other authors. The paper ends with the presentation of the numerical results and a few conclusions. We are also presenting several directions for future research in this field. [ABSTRACT FROM AUTHOR]

This paper analyses the selection of radiators using the method of the degree of belonging to the optimal variant. This paper is among the first tries of this type from Romania. A case study shows the practical application of this algorithm. The paper ends with the presentation of the numerical results and a few conclusions. The models proposed may be used in practice in case of feasibility studies, for master degree theses as well as for Ph.D. theses. The method of degree of belonging to the optimal variant can also be used for the selection of other types of materials for the installations related to the constructions. [ABSTRACT FROM AUTHOR]
