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.
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.
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.
Underground spaces having features such as stability, resistance, and being undetected can play a key role in reducing vulnerability by relocating infrastructures and manpower. In recent years, the competitive business environment and limited resources have mostly focused on the importance of project management in order to achieve its objectives. In this research, in order to find the best balance among cost, time, and quality related to construction projects using reinforced concrete in underground structures, a multi-objective mathematical model is proposed. Several executive approaches have been considered for project activities and these approaches are analyzed via several factors. It is assumed that cost, time, and quality of activities in every defined approach can vary between compact and normal values, and the goal is to find the best execution for activities, achieving minimum cost and the maximum quality for the project. To solve the proposed multi-objective model, the genetic algorithm NSGA-II is used.
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.
Within the boundaries of many municipal urbanized areas, large grounds are found, from which the noise is emitted into the environment, surrounded by the regions liable to acoustic protection. Such a condition generates many problems including also those ones related to the lack of the fulfillment of requirements concerning environmental protection against excessive noise. Therefore the aim of vital importance is the proper management of municipal grounds, both in view of the investment in policy steering, especially of new investments, and in the case of activities aimed at maintaining or restoring (revitalizing) the acoustic properties on the grounds that have already been used or simply degraded before.
Keeping the scale of the problem in mind, such activities must be carried on not temporarily, but must have a systemic character. The structure of every system is characterized by the appropriate relationships among their elements and the properties of those relationships. In case of the noise management system, the elements of such a system are the activities connected with the management itself that are the actions which rely on specifying the aims and causing their realization within the scope and on the grounds subject to the managing entity. The superior aim of such activities should be to supply the tools for improvement of management and in the process of taking decisions that relate to investments including the of optimization conditions and maintenance of socio-economic importance of such areas.
The article presents relationship between history and management. Methodological inspirations between these disciplines have been shown and also the achievements carried out within the history of business and organizational theory have been described. The author has characterized the “historical turn” in organizational researches in the 1990s of XX century. In the subsequent part of the article, three methodological approaches have been characterized, namely: narrative research and storytelling, business history, and historical perspective in organizational research. The achievements of Polish researchers in the distinguished areas of research were taken into account. At the end, barriers to greater interest of using the historical perspective in the research of organizations, conducted by Polish researchers, have been presented. They are as follows: small share of historical knowledge in the education of management adepts, domination of a historical paradigms in organization and management research, the lack of continuity in the development of Polish organizations and scientific reflection on organizations and management in the 20th century and low historical awareness of Polish entrepreneurs and managers.
Maintenance of process plants requires application of good maintenance practice due to
a great level of complexity. From a plant maintenance point of view, the most significant activity
is turnaround, an activity carried out through project task with long planning process
period and very short execution period, which makes it one of the most complex projects
of maintenance in general. It is exactly this kind of maintenance that is based on multidisciplinarity
which has to be implemented through the system of quality management on all
levels of maintenance management. This paper defines the most significant factors determining
the process of turnaround projects quality management and its efficiency. Such relation
is observed through moderating influence of complexity on process management efficiency
in the turnaround project. The empirical research was conducted based on the survey of
turnaround project participants in five refineries in Croatia, Italy, Slovakia and Hungary.
For exploring the influence of research variables testing of the target relation is carried out
by applying logistical regression. Research results confirm the significance of complexity as
variable that significantly contributes to the project performance through the moderating
influence on success of the project, as well as the influence of an efficient management on
a plant turnaround project key results. Beside theoretical indications, practical implications
that arise from this research study mainly refers to management process of the industrial
plant maintenance project.
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.
