Badanie autokorelacji przestrzennej krwiodawstwa w Polsce

Aim of this study is to investigate the presence of spatial dependence in the level of development of the blood donation. Analysis of spatial data will identify the similarities and differences between provinces. Using the tools of spatial statistics will be revised hypothesis of the presence of spatial autocorrelation. Using local statistics there will be highlighted the major development centers of the blood donation in the country. The possibility of using measures of spatial autocorrelation will be shown by the example of analysis of diversity of the population per one blood donor, per one blood unit for particular provinces or diversity in the number of hospital beds per one blood unit for provinces. Then there will be formed the synthetic development measure of provinces on the basis of Hellwig's synthetic development measure. Assumed that determined development measure will illustrate overall situation of blood donation in particular province

A comprehensive study of classical heuristic algorithms used in the process of solving Transportation Problem

Background: Transportation Problem (TP) is a special case of integer programming, characterised by indisputable practical significance (in particular in the area of logistics). For this reason, many techniques have been proposed to solve the problem both in optimum and approximate manner. The problem of selecting an effective technique for determining a suboptimal solution for TP was addressed by many researchers, however the implementation of only certain heuristics, 'test bed' applied, as well as non-performance of statistical tests make it impossible to clearly identify the recommended approach to application of heuristics in TP, leaving a research gap which determined the writing of this article. The additional purpose of this paper is to provide a summary of selected approximate methods, taking into consideration the number of iterations necessary to design the optimal solution by means of Modified Distribution (MODI) method and to demonstrate potential correlations between the parameters describing a problem instance and the efficiency of the methods. Methods: This paper presents a comparative study of four classic techniques (NWC, LCM, VAM and RAM). The tests were performed on three sets of 2,500 pseudo-randomly generated tasks and the observations were also checked by means of the Wilcoxon Signed-Rank Test and Pearson correlation coefficient. Results: The results confirms that VAM is characterised by a significant quality of the determined results, whereas NWC develops solutions of low efficiency. However, contrary to the observations made for small TP instances, RAM was characterised by a higher error value than LCM for huge set, demonstrating the impossibility to generalise results obtained for small problems (presented e.g. in literature), in order to determine their efficiency for higher instances. Conclusions: It is recommended to apply VAM both for the determination of initial solution in MODI method and for performing allocation of resources, using only heuristics. However, taking into consideration the utilitarian approach and possible occurrence of the necessity to solve TP instances without using the appropriate software, it is recommended to use LCM for solving large instances of TP. The presence of strong correlation between the number of nodes describing the TP instance and the number of iterations necessary to determine the optimal solution by MODI method has been identified

Multiple probabilistic traveling salesman problem in the coordination of drug transportation - In the context of sustainability goals and Industry 4.0

Improving the effectiveness of route planning, especially in road transport deliveries is a challenge we need to face in the context of advancing climate change and the sustainable development goals. The main aim of the paper is to demonstrate the above average and utilitarian significance of the multiple probabilistic traveling salesman problem (MPTSP) in the coordination and modeling of sustainable product transportation, which is a novelty at the theoretical, conceptual, methodological and empirical level. We propose a new, hybrid algorithm of solving MPTSP instances (it connects harmony search, k-means and 2-opt), which can be successfully used in economic practice for coordination and modeling of Industry 4.0. The effectiveness of proposed approach is tested using a case study of drugs distribution services and datasets obtained from the transportation enterprise located in Poland. The study focuses on the issue of planning routes, with particular emphasis on the changing demand of customers. It should be stressed that this work may be of interest to researchers but also to management practitioners. The value added of this research lies in the innovative modeling the coordination of sustainable drug transportation as an instance of MPTSP and proposing an effective method to solve it. The main research results confirm that proposed method contributes to overall sustainability of studied supply chain

Success Factors of Blood Donation System in Poland

Sense of citizens' health security is one of the most important components of quality of life. Ensuring security in this area is the subject of the activities described in various policies and strategies of the state. One of the specific conditions of the health security of the state is to ensure the availability of human blood treated as a drug. In Poland, the environment in which it is implemented management of blood resources in blood donation system. Blood donation system is composed of independently functioning blood supply chains, implementing flows (blood and its components) from donor to recipient. The success of the system, and thus the chain ensuring availability of blood (as a drug) a sufficiently high level. The availability of blood as a raw material is dependent on the demographic population, as well as its willingness to honour the donation. In this paper the author presented the important relationship between the above factors and components

Noise problems in modern cities

Przedmiotem opracowania jest wskazanie na problematykę zanieczyszczeń we współczesnych miastach, a w szczególności zanieczyszczenia hałasem, jego przyczyny, skutki i możliwości ograniczania (programy Unii Europejskiej) – jako główną determinantę wyboru lokalizacji firm czy miejsc zamieszkania. Bez wątpienia wolne od zanieczyszczeń otoczenie może być źródłem przewagi konkurencyjnej i wyższej jakości życia mieszkańców miasta.The article takes the issues of noise problems in modern cities. The subject of this paper is to indicate pollutants – in particular noise pollution – its sources, consequences and possibilities of its reduction (programs of the European Union) as the main determinants of companies and places of residence location choice. Without a doubt, environment free from pollution is a source of city competitive advantage and a higher quality of life for city residents
