Abstrakt

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.

The presence of the spare parts stock is a necessity to ensure the continuity of services. The supply of spare parts is a special case of the global supply chain. The main objective of our research is to propose a global spare parts management approach which allows decision makers to determine the essential points in stock management. Thus, it is important for the stock manager to evaluate the system considered from time to time based on performance indicators. Some of these indicators are presented in the form of a dashboard. The presentation of this chapter chronologically traces the progress of our research work. In the first part, we present the work related to the forecast of spare parts needs through parametric and statistical methods as well as a Bayesian modelling of demand forecasting. To measure the appreciation of the supply of spare parts inventory, the second part focuses on work related to the evaluation of the performance of the spare parts system. Thus, we concretize the link between the management of spare parts and maintenance in the third part, more precisely, in the performance evaluation of the joint -management of spare parts and maintenance, in order to visualize the influence of parameters on the system. In the last section of this chapter, we will present the metaheuristic methods and their use in the management of spare parts and maintenance and make an analysis on work done in the literature.

Industry 4.0 promises to make manufacturing processes more efficient using modern technologies like cyber-physical systems, internet of things, cloud computing and big data analytics. Lean Management (LM) is one of the most widely applied business strategies in recent decades. Thus, implementing Industry 4.0 mostly means integrating technologies in companies that already operate according to LM. However, due to the novelty of the topic, research on how LM and Industry 4.0 can be integrated is still under development. This paper explores the synergic relationship between these two domains by identifying six examples of real cases that address LM-Industry 4.0 integration in the extant literature. The goal is to make explicit the best practices that are being implemented by six distinct industrial sectors

Abstract Industry 4.0 (I4) as a concept offers powerful opportunities for many businesses. The set of Industry 4.0 technologies is still discussed, and boundaries are not perfectly clear. However, implementation of Industry 4.0 concept becomes strategic principle, and necessary condition for succeeding on turbulent markets. Radio Frequency Identification (RFID) was used before I4 emerged. However, it should be treated as its important part and even enabler. The question arises how adoption of RFID was impacted by I4 paradigm. Therefore, to answer this question a set of technology management tools was selected and applied to forecast RFID potential development in forthcoming years. Moreover, case studies were conducted for technology management tools and their applications for RFID for qualitative discussion of its relevance. It aimed to prove that existing toolset should be applied for modern technologies related to I4. Tools were proven to be necessary and successful. However, some specific challenges were observed and discussed.

Abstrakt

The industrial revolution taking place since the 18th century has brought the global economies to the stage of mass production, mass industrialization and spreading ideas connected with its efficiency. The most famous of its kind is Fordism and its modern variations called Post- Fordism or Neo-Fordism. We can still see traditional way of producing things in some parts of the world, and the leading economies are using Ford’s ideas or the modifications of the Ford’s concepts. But there is a question about the place of these models in the modern economy, especially because mass-production causes mass-waste and modern societies has woken up to the reality of the global pollution, climate change or just the simple fact that the amount of the raw materials is limited. The social mood is slowly changing so there should be a change to the way we produce and consume things as well. There is a question: can we proceed within existing models or should we think outside the box so we can invent more suitable way of looking at efficiency and effectiveness. The objective of this paper is to contribute to the discussion about the future of how are we going to produce things. It is based on the literature review considering Fordism and its variations, Product Life Cycle facing issues like pollution, massive waste and changes in modern economy, as well as on the case study of implementing waste reduction activities in the product’ design phase in the industrial plant based in one of the EU countries – Poland.

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.

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.

Abstrakt

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.

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.

Abstrakt

Instytucja zarządzania statkami morskimi (ship management) nie jest zbyt dobrze znana ani polskiemu prawu, ani polskiej doktrynie prawa morskiego, pomimo tego że rola zarządzającego statkiem (ship manager) rosła sukcesywnie przez wiele lat. Jej początki przypadają na lata osiemdziesiąte poprzedniego stulecia, w okresie poważnych zmian na rynku żeglugowym, gdy dochodziło do wielu bankructw przedsiębiorstw armatorskich i gdy banki hipoteczne musiały zwracać się do fachowych podmiotów zarządzających statkami o pomoc w prowadzeniu działalności żeglugowej.

Trzydzieści lat temu, w 1988 r. BIMCO opublikowała pierwszy wzorzec umowy o zarządzanie statkiem o nazwie SHIPMAN, który zapewnił pewną równowagę pomiędzy prawami i obowiązkami armatora i zarządzającego statkiem oraz jednolitość w szeroko stosowanych na rynku żeglugowym umowach tego rodzaju, szczególnie w podziale odpowiedzialności pomiędzy stronami.

Po wejściu w życie w 1998 r. Kodeksu ISM, który wprowadził do prawa międzynarodowego instytucję Company jako podmiot odpowiedzialny za bezpieczną eksploatację statku, rola zarządzającego wzrosła niepomiernie. Było to między innymi przyczyną tego, że BIMCO przygotowała nowy formularz umowy o nazwie SHIPMAN 98. Po kolejnych kilku latach formularz został uaktualniony i jego nowa wersja została wydana w 2009 r.

Głównym celem artykułu jest przybliżenie czytelnikowi zagadnień związanych z zarządzaniem statkiem morskim i podmiotem nim zarządzającym (ship manager), przez omówienie i przetłumaczenie na język polski opracowanego przez BIMCO nowego wzorca umowy o zarządzanie statkiem o nazwie SHIPMAN 2009.

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.

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.

Abstrakt

W ostatnich latach w górnictwie węgla kamiennego coraz częściej praktykuje się zlecanie firmom zewnętrznym wykonywanie różnego rodzaju prac/usług. Wiąże się to z zatrudnianiem pracowników przez firmy zewnętrzne. Praktyki te nie zawsze są dobrze postrzegane przez pracowników kopalń, gdyż mogą wpływać w sposób zarówno pośredni, jak i bezpośredni na ich wynagrodzenie i warunki bezpieczeństwa. Po pierwsze bardzo często pracownikami firm zewnętrznych są osoby, które traktują prace w górnictwie jako możliwość szybkiego lecz krótkotrwałego (czasowego) sposobu na szybki zarobek. W związku z tym firmy zewnętrzne bardzo często wynagrodzenie swoich pracowników obliczają nie na podstawie czasu pracy (tj. liczby przepracowanych godzin), lecz w zależności od konkretnie wykonanej pracy. Takie zatrudnienie nazywane jest pracą na akord, zatem pracownicy akordowi, by uzyskać wyższe zarobki, pracują szybciej i wydajniej. To z kolei może wpływać na podnoszenie norm pracownikom zatrudnionym przez przedsiębiorstwo górnicze. Ponadto pracownikami firm zewnętrznych są bardzo często emerytowani górnicy i w związku z tym koszty, jakie ponoszą zatrudniający ich pracodawcy, są zdecydowanie niższe niż przedsiębiorstw górniczych. Dodatkowo tacy pracownicy, aby nie stracić świadczenia emerytalnego, pracują za dużo niższą stawkę. Praca zlecona na zewnątrz wykonywana zazwyczaj w pośpiechu (na akord) nie sprzyja przestrzeganiu przepisów bhp, co może wpływać na bezpieczeństwo pracy wszystkich zatrudnionych. W artykule pokazano, w jaki sposób pracownicy kopalni oceniają outsourcing prac podziemnych. Dla realizacji celu przeprowadzono badanie ankietowe wśród pracowników kopalń jednej ze spółek węglowych na Śląsku. W badaniu tym udział wzięli losowo wybrani pracownicy dołowi przedsiębiorstwa górniczego. Ankieta była anonimowa, co niewątpliwie mogło mieć wpływ na szczerość respondentów. Badanie przeprowadzane było w kilku kopalniach wybranej spółki. Część ankiet była prowadzona w wersji elektronicznej, a część w wersji papierowej. Analiza ankiet pozwoliła zrozumieć powody niechęci pracowników spółek węglowych do zlecania prac dołowych firmom zewnętrznym. To z kolei można wykorzystać do lepszego zarządzania zasobami ludzkimi, w tym w szczególności planowania motywacyjnego systemu wynagradzania.

Zagadnienie zarządzania statkami (ang. ship management) jest rzadko poruszane w polskiej doktrynie. Istnieją różne przyczyny takiego stanu rzeczy, aczkolwiek niewątpliwie znaczący jest priorytet nadany w politycznym, prawnym jak i ekonomicznym dyskursie zagadnieniom prawnym poświęconym właścicielom statków. Obecny trend utrzymuje się pomimo faktu, iż ponad 73% światowego tonażu jest zarządzane przez specjalistyczne podmioty „ship managerskie”.

Analiza ekonomiczna rok po roku dostarczała dowodów, że Polska przestała być krajem liczącym się pod względem ilości posiadanych przez nią statków i ten trend nie ulegnie odwróceniu w perspektywie krótko i średnioterminowej. Polska może jednak odegrać kluczową rolę w świecie żeglugi poprzez przekształcenie się w centrum zarządzania statkami. Niniejszy artykuł ma na celu przedstawienie wybranych aspektów zarządzania statkami morskimi.

Bridges are particularly vulnerable elements of transport infrastructures. In many cases, bridge structures may be subject to higher volumes of traffic and higher loads as well as more severe environmental conditions than it was designed. Sound procedures to ensure monitoring, quality control, and preventive maintenance systems are therefore vital. The paper presents main challenges and arriving possibilities in management of bridge structures, including: relationships between environment and bridge infrastructure, improvement of diagnostic technologies, advanced modelling of bridges in computer-based management systems, development of knowledge-based expert systems with application of artificial intelligence, applications of technology of Bridge Information Modelling (BrIM) with augmented and virtual reality techniques. Presented activities are focused on monitoring the safety of bridges for lowering the risk of an unexpected collapse significantly as well as on efficient maintenance of bridges as components of transport infrastructure – by means of integrated management systems. The proposed classification of Bridge Management Systems shows the history of creating such systems and indicates the expected directions of their development, taking into account changing challenges and integrating new developing technologies, including automation of decision-making processes.
