The aim of this article is to identify opportunities for using synergies obtained by incorporation of the two methods of management: Lean Management and Agile Management on the example of the process of column concreting. Despite the seemingly contradictory assumptions the two concepts complement each other in analysed example. The strategy is based on using the idea of "one piece flow" in accordance with the Lean Management which led to a reduction of costs due to increased turnover of formwork. At the same time the success of the project resulted in a significant dependence on the ability to provide a rapid response to changing conditions during in the maturation of concrete (depending on weather conditions, which can be expected on the basis of projections having different reliability). The simultaneous use of Lean and Agile Management allowed to achieve positive results for different scenarios of environment impact on the analysed process.
Author explains a necessity of supply optimization to construction sites with small storage areas. This paper takes account of conditions existing in Poland. From among all factors discussed by the author, first of all, we should point at construction works on plots located in densely built-up areas, obtained by demolition of existing buildings, as well as a necessity of plots utilization after demolished buildings that technical conditions do not allow for further exploitation.
The purpose of this article is to present the preparation of Project Risk Assessment Methodology and its mitigation in complex construction projects. The main text provides a summary of the approach, the method used and the findings. The conclusions have been drawn that the proper tools for quantifying risks have to be based on the criteria specific for mathematical statistic and probability or at least fuzziness. Function, which makes possible to categorize any risks into one of the five categories, is a combination of probability and the impact on one of the items: people and their safety or budget, cost, schedule and planning or quality and performance. An attempt was made to express numerically the relationship between risks impacts and their level of likelihood. Also, a method of associating the influence of projects risks impacts on the extent of the likelihood of project risk occurrence which makes possible to determine the direction and the strength of this relationship was presented.
Revitalization programme and spatial and strategic management, Revitalization programme is the set of integrated activities in favour of a local community, space and economy, which are territorially concentrated and performed by revitalization stakeholdres. These activities should be based on revitalizing strategic and spatial management strongly oriented to improvement of life and living conditions of a local community. The aim of the article is to explain the essence of revitalization programme as a scenario of spatial and strategic activities of the borough authorities. The authors proves that spatial management and strategic management are the tools that enable them to conduct the revitalization process. In the study there is a passage devoted to theoretical and operational meaning of the subject issue. Also the example collected from The Local Revitalization Programme of Krobia Borough, which was elaborated in 2017, has been presented.
The concept of a Ship Management is vaguely known in the Polish law and legal doctrine although the role of the Ship Manager has become quite complex through the years. It started in the eighties when there was a deep change in the shipping market as many shipping companies became bankrupt and mortgagor banks had to turn to ship managers for help. Thirty years ago in 1988 BIMCO published the first Ship Management Contract which provided the market with a standard document striking a fair balance between the rights and obligations of the owners and the managers, giving some uniformity in the widely used in-house contracts, particularly in the apportionment of liability between parties. After the implementation of the ISM Code in 1998 and creating the entity called “Company” as a subject responsible for a safe operation of a vessel the ship manager’s role rose extremely. It caused, among other factors, that BIMCO issued the world wide known form of contract named SHIPMAN 98, which was then superseded by its new version issued in 2009. The main goal of this article is to bring a reader closer to the issue of a Ship Management and the Ship Manager through a Polish translation of this modern BIMCO form named SHIPMAN 2009.
Production rates for various activities and overall construction project duration are significantly influenced by crew formation. Crews are composed of available renewable resources. Construction companies tend to reduce the number of permanent employees, which reduces fixed costs, but at the same time limits production capacity. Therefore, construction project planning must be carried out by means of scheduling methods which allow for resource constrains. Authors create a mathematical model for optimized scheduling of linear construction projects with consideration of resources and work continuity constraints. Proposed approach enables user to select optimal crew formation under limited resource supply. This minimizes project duration and improves renewable resource utilization in construction linear projects. This paper presents mixed integer linear programming to model this problem and uses a case study to illustrate it.
In recent years, the outsourcing of a variety of different activities has been more commonly observed in the coal mining industry. This is connected with employing workers by external companies. These practices are not necessarily perceived as good ones by mines’ employees because they may influence their remuneration directly or indirectly. Firstly, as external employees treat work in mining company as a source of a quick income. Therefore, external companies often calculate their employees compensation not based on working time (i.e. hours) but on the basis of a specific, accomplished task. Such employment is called piecework, whereas the workers employed in this kind of system are called output workers/piece workers. Therefore, to receive higher wages in these companies, employees carry out their tasks faster and more efficiently. This, in turn, can affect the standards of workers employed by the mining company. In addition, outsourced workers are often retired miners, so the costs incurred by employers are significantly lower. In addition, in order to not to lose the retirement benefit, they work for a much lower rate. On the other hand, outsourced work can be done in a hurry (on a piece rate), which is not conducive to compliance with safety regulations, therefore mine employees may feel unsafe. This article aims to present how mine employees assess outsourcing underground works. In order to achieve this aim, a survey was carried out among employees of one of the coal mine companies in Silesia. Participants of the survey were randomly chosen among underground miners employed at one mine company. The survey was anonymous which obviously might have influenced respondents’ honesty in answering. The survey was carried out in several mines of the chosen company. In some of them the survey was carried out online and in the remaining ones it was filled out on paper. Analyzing the survey results allowed for a better understanding of the reasons of the disapproval of outsourcing underground works. This, in turn, may be used for better human resources management including, in particular, planning an incentive based pay system.
Ship management is a topic that has rarely been approached in the modern Polish maritime legal sciences. There are numerous reasons behind the present state of affairs but it seems that the foremost one is, that the focus in political, legal and economic discourse is still on the legal aspects of ship ownership. This trend continues despite the fact that today over 73% of world shipping tonnage is managed by the specialized ship management entities. An economic analysis has proven that year after year Poland was ceasing to be a large ship owning nation, it used to be, and that this trend is unlikely to be reversed in the short and mid-term perspective. Poland may, however, still continue to play a vital role in the world of shipping by becoming a ship management centre. This article aims to introduce the Readers to the selected aspects of ship management operations.

This paper is a result of joint work of specialist from two diff erent areas: management and environmental protection. The interdisciplinary character of the paper is characteristic for smart cities.
We talk to Dr. Bogdan Jaroszewicz, head of the Białowieża Geobotanical Station of the University of Warsaw, about how planned logging in the Białowieża Forest will damage not only the forest itself but also Poland’s image around the globe.
Parental participation in co-management of state school becomes a key issue for democratization of public life in poland and for the quality and effectiveness of civic education of the young. The system of education needs social control, first of all of those whose children are subjected to school duty. “Such will the Republics of poland be as their youth is educated” is the thesis forming the foundations of the school system in the 3rd Republic of Poland. In compliance with the postulates and ethics of Solidarity, the system was supposed to be self-governing. What is analyzed in this study is the relation between politics and school education in the normative-empirical dimension. The (so far unpublished) research results of the author's own studies on democratization of state education are popularized here. This is done, after the dispute on some studies diagnosing the nationwide lack of socialization, in order to indicate subsequent aspects of fiction and appearances of the central authority, the rule of safe position employment, common paralysis of parental care, as well as natural expectations and aspirations which should be fulfilled by the subjects running state schools.
An accurate use of the ability to steer computer efficiency is essential from the database point of view. Effective resource allocation is dependent on the performance indicators gathered from running systems. There must be an appropriate balance between accurate measurements, performance indicators and speed of the reallocation algorithms of the computing resources. The extended measurement of efficiency which the authors propose for applications is: the average number of queries within a time unit for particular groups of users. This paper presents an analysis of using the Workload Manager utility in the AIX 5L operating system to improve the efficiency of applications in the MySQL database environment, and an analysis of methods which allows the use of Workload Manager for steering efficiency dynamically.
In the process of determining the content of impurities, including fossil fuels, crude oil, coke, pitch, plastics, glass, slag, rust, metals, and rock dust, in charcoal and wood briquettes via microscopic examination, the question of the use of ashes from the combustion of grill fuels (taking the scale of the new national sport into account, commonly referred to as „weekend grilling”) was raised. Another reason for addressing this issue was the question regarding the use of organic additives to acidified soil (mineral) fertilizers submitted by one of the clients of the bituminous coal and reservoir rocks analysis laboratory. In addition, the manufacturer of gardening soil has also expressed an interest in an unconventional deacidifying agent; the introduction of a new product with a unique ingredient is considered as a chance to stand out from the competition. A review of the literature shows that attempts to use ashes obtained from the biomass combustion in power boilers have been made. However, due to the biomass composition and additives and pollutants used in biomass for energy purposes, the production of such mixtures has been dropped. Based on the data from numerous samples of grill fuel, which meet the requirements regarding the content of impurities set out in the PN-EN 1860-2 standard, the question of the possible use of ash obtained from charcoal and wood briquette grilling as a component for use in the production of acidified soil (mineral) fertilizers was discussed. The article will present the amount of material obtained based on the statistical sales of barbecue fuels based on the experimentally calculated ash mass resulting from the combustion of 1 kg of starting material. In addition, a logistic proposal for obtaining ash from individual grill users will be developed. On the day of the submission of the present work, the results of the chemical analysis of charcoal and wood briquettes subjected to the gasification process have not yet been obtained. However, based on the microscopic analysis, it can be concluded that the content of impurities in the examined samples is highly unlikely to prevent the use of the mentioned ashes in agriculture.
One of the most important business areas of the company is the management of working capital. Energy companies that produce electricity and heat are the main consumers of steam coal, so their decision concerning stock levels is a major determinant of supply schedules. These decisions depend on legal and technical requirements as well as economic aspects. The seasonality of coal consumption jointly with pre-purchase costs and storage costs has a straight impact on delivery scheduling in a parabolic way. There is a divergence in expectations regarding delivery schedules among the coal market participants (energy, mining, transport companies). The purpose of this article is to present the concept of pricing of steam coal and transport service on the Polish market, assuming the use of price incentives, resulting in delivery scheduling during the year. The article presents selected theoretical content in the field of coal logistics and working capital management in the company, the expectations of the steam coal market participant regarding delivery schedules have been identified. The proposed concept of pricing steam coal and transport service should be discussed further in scientific and expert work.
Water reaches a river in the form of surface runoff (precipitation that has not seeped into the ground) or underground outflow (groundwater). Both of these factors affect the erosion and river deposition processes that shape the river valley. Understanding them is crucial for effective river management.
Municipal waste management has been an area of special interest of the European Commission (EC) for many years. In 2018, the EC pointed out issues related to municipal waste management as an important element of the monitoring framework for the transition towards a circular economy (CE), which is currently a priority in the economic policy of the European Union (EU). In the presented monitoring framework, 10 CE indicators were identified, among which issues related to municipal waste appear directly in two areas of the CE – in the field of production and in the field of waste management, and indirectly – un two other areas – secondary raw materials, and competitiveness and innovation. The paper presents changes in the management of municipal waste in Poland in the context of the implementation of the CE assumptions, a discussion of the results of CE indicators in two areas of the CE monitoring framework in Poland (production and waste management), and a comparison of the results against other European countries. In Poland, tasks related to the implementation of municipal waste management from July 1, 2013 are the responsibility of the municipality, which is obliged to ensure the conditions for the system of selective collection and collection of municipal waste from residents, as well as the construction, maintenance and operation of regional municipal waste treatment installations (RIPOK). The municipality is also committed to the proper management of municipal waste, in accordance with the European waste management hierarchy, whose overriding objective is to prevent waste formation and limiting its amount, then recycling and other forms of disposal, incineration and safe storage. The study analyzed changes in the value of two selected CE indicators, i.e. (1) the municipal waste generation indicator, in the area of production and (2) the municipal waste recycling indicator, in the area of waste management. For this purpose, statistical data of the Central Statistical Office (GUS) and Eurostat were used. Data has been presented since 2014, i.e. from the moment of initiating the need to move to the CE in the EU. In recent years, there has been an increase in the amount of municipal waste generated in Poland as well as in the EU. According to Eurostat, the amount of municipal waste generated per one inhabitant of Poland increased from 272 kg in 2014 to 315 kg in 2017. It should be noted that the average amount of municipal waste generated in Poland in 2017 was one of the lowest in EU, with a European average of 486 kg/person. Poland has achieved lower levels of municipal waste recycling (33.9%) than the European average (46%). The reason for Poland’s worse results in the recycling of municipal waste may be, among others, the lack of sufficiently developed waste processing infrastructure, operating in other countries such as Germany and Denmark, and definitely higher public awareness of the issue of municipal waste in developed countries. Municipal waste management in Poland faces a number of challenges in the implementation of GOZ, primarily in terms of achieving the recycling values imposed by the EC, up to a minimum of 55% by 2025.
Cities play a special role in the process of sustainable development of the country. The city management plays a fundamental role in this challenge. The mayor should become a manager and manage the city based on a strategic marketing management model. Thanks to this, it can optimally use available financial instruments that give the opportunity to achieve strategic development goals of the city.
With the increase in the mass of municipal waste generated, the demand for facilities dealing with their development is increasing. The aim of the research was to determine environmental and anthropogenic factors affecting the location of waste management facilities and an attempt to indicate potential locations for selected waste management facilities in the communes of the Sądecko-Gorlicki region. The scope of work included: a review of existing waste management facilities in the studied region, acquisition of geodatabase for digital data, analysis of the distance between the waste management facilities and environmental or anthropogenic elements, and analysis of potential locations designated in the GIS based on the developed criteria.As a result of spatial analyzes, it was found that in the study area, there are 3 places of potentiallocations for installation of municipal solid waste treatment facilities.
Modern cities are increasingly promoting their own individual brands to gain a competitive advantage. 28 Polish cities, after joining the Cittaslow international network of cities, can additionally use their native brand in their activities. The aim of the author was to answer the question: should cities only use an individual brand, or maybe they can support these activities with a common brand strategy. The growth of interest in individual brands of 28 cities belonging to the Cittaslow network has been evaluated, also their popularity, popularity of the native brand on the Facebook, and the use of the Cittaslow brand by cities on their websites were analysed. It was noticed that not all cities use the Cittaslow logo. But most cities in Cittaslow publish a link to the network and brand information on their websites. The native brand Cittaslow is in Poland at the positioning stage but probably its popularity will grow as the benefits from using it begin to be noticed.
The analysis of provisions of Local Spatial Management Plans and selected cases of practical implementation of such provisions showed, that the provisions of spatial law practically stay without any relation to rules of urban composition and spatial order. The research was limited to analysis of urban composition, without considering all the conditions for planning process and its results. The town planning is treated in this article as planned space resulted from clear urban concept based on general urban composition rules. Town planning does not refer in this case to spatial chaos which can be a result of implementation of Local Spatial Management Plan.
The main issues in hunting management in Belarus are environmental protection, social-cultural, and economic problems. The total area of hunting grounds in the area is approx. 16.6 million hectares, including approx. 7.4 million hectares of forestlands, 8.2 million hectares of farmlands, and approx. 1 million hectares of wetlands. The territory of Belarus is characterized by lowland terrain features and a large number and area of stagnant and flowing waters. Protected areas (parks, reserves) account for 8.7% of the total area of the country. The hunting management is implemented in 250 legal entities. The main user of hunting grounds is the Belarusian Associa-tion of Hunters and Fishermen managing an area of ca. 10 million hectares. Hunting management is implemented based on national legislation of 2005. In 2015, the population of the moose was 32 thousand, deer – 15.2 thousand, roe deer – 74.6 thousand, beaver –58.3 thousand, capercaillie – 8.5 thousand, black grouse – 37.3 thousand. Over the last 10 years, the population of moose has doubled and the population of deer and roe deer has increased 2.5-fold and 1.5-fold, respectively. In relation to the habitat potential and breeding recommendations, the current populations of game species (moose, deer, and roe der) do not exceed 70% of the expected number. There are wild boars, but their numbers have been substantially reduced from 80 thousand to 2–3 thousand due to the epizootic threat (ASF). The hunting size is limited with reference to the number of individual species and the abundance dynamics. The level of exploitation of Cervidae is 10–13% of the total abundance, beavers – ca. 15%, and capercaillie and black grouse – 8–10%. Wolves are a hunting species and their population size over the last 10 years increased from 1000 to 1600 individuals, and the culling size increased from 700 to 1400.
The paper presents the author’s reflection regarding the recent transformations of the city of Krakow. The study is focused on the changes that are novelties or distinctive to the city. The conclusions indicate activities that should be treated by city authorities as challenges for the public management of the metropolitan scale.
The paradox of enterprise management is the company must continually change in a dynamic and difficult-to-predict environment in order to achieve business continuity and profitability goals. The relatively low efficiency and awareness of the need for change at network organizations means the problems connecting with changes implementation, identification of conditions limiting their realizations and importance of final results are still significant. This article described this issue by the diagnosis of current state of the change management in various types of network organizations and showing how this state can be improved in the future. Assuming the organization will strive for conscious and organized change management.
