Opis:
In a previous work [1], we have defined an object library that allows the building of architectural models of urban traffic systems. In this work we illustrate the procedures that enable us to produce a system simulator starting from the architectural model of an urban vehicular traffic system.

Opis:
This work is part of the research activities developed in our department on the construction of vehicle traffic system simulators (TASKQuart.22(2) 135 [1],20(1) 9 [2],17(3) 155 [3],20(3) 273 [5],14(4) 405 [6],9(4) 397 [7],Simulation Modelling Practice and Theory 17 (4) 625 [8]). The modeling of the traffic system is implemented through the use of queuing networks. In this case we analyze, through a simulation, the impact on traffic flows of a structural change that the Municipal Administration has implemented on the urban road system. The study refers to some works published by us previously about the procedures applied by us to build a simulator. In this case we have developed software allowing us to analyze the data tracked by the system simulations to display it graphically. This procedure enables us to clearly compare the traffic system behavior in its new configuration with the traffic system behavior in the previous configuration.

Opis:
This paper outlines a study carried out to answer the questions asked by an architect of the Siena Municipality Office during a conference at our Department on the managementof traffic flows through the Siena North city road system. The purpose of the study was to ascertain if changes in the road system introduced and included in the new City Developmen tPlan would resolve the current traffic congestion issues. In order to answer this question, we used the technology for the development of vehicle traffic system simulators which was introduced during our previous projects (TASKQuart.14(4) 405,17(3) 155,20(1) 9,20(3) 273).

Opis:
In the previous works we presented a study for modeling and simulation of vehicular traffic systems based on queuing networks. Specifically, in paper (Pasini and Bianchini, 2019), we studied the urban network located in North Siena, in the city of Siena (Italy), in its actual layout, after the Municipality had introduced some changes for vehicular flow management. This system is based on two roundabouts and a crossroad, as shown in Figure 1. In this work, we are going to conclude our previous study, comparing the actual vehicular flow and the flow derived from an alternative system, foreseen by the PRG of the Municipality of Siena which is composed of three roundabouts and which has not been implemented yet.

Opis:
W artykule przedstawiono i zanalizowano problem zarządzania zasobami w służbie zdrowia. Omówiono podstawowe zagadnienia w procesie alokacji zasobów medycznych. Zaprezentowano przykłady zastosowania wybranych metod: programowania matematycznego (liniowego, całkowitoliczbowego, celowego, sieciowego), teorii kolejek, modelowania symulacyjnego, systemów hybrydowych oraz standardowych metod kosztowo-efektywnościowych do analizy zagadnień, związanych z podziałem zasobów w systemach opieki zdrowotnej. Przedyskutowano użyteczność tych metod do rozwiązywania szczegółowych problemów dotyczących zarządzania zasobami medycznymi.
Various issues referring to general problems of resource allocation in the area of healthcare were discussed in the article. Fundamental questions regarding the process of allocating healthcare resources were pointed out. The topics were presented according to the categories of methods used to potentially solve these problems. The following approaches were considered: chosen methods of mathematical programming, queuing theory, simulation, hybrid algorithms combining, among others, artificial intelligence and other techniques, as well as standard cost-effectiveness methods. Such methods were applied to the following problems: analyzing the current state of health care units and presenting proposals of changes to such systems. The modifications suggested referred to: allocation of material resources, planning the work schedules of medical personnel and patient admission. The question of determining the effectiveness of various medical strategies was also discussed. The article clearly underlined the importance and complexity of the problem of managing healthcare resources.
