Opis:
Currently entrepreneurs have the opportunity to use many methods and tools that support production management, quality and improvement of working safety. A method worth paying attention to is the 5S method, which brings order and discipline to the workplace. The article presents practical aspects of the implementation of the 5S method using five simple steps that give the real benefits to a company. Particularly the specific solutions that can be applied at every stage of the implementation of the 5S method is indicated. Also innovative ways of conducting internal audits are presented. In addition, a model for the implementation of the 5S concept was proposed, which supports maintaining the healthy standards at a high level. It has been pointed out that the implementation of 5S rules must be constantly monitored and improved. Therefore, supervision and motivational activities are particularly important, especially from the side of leaders and managers represented an organization.

Opis:
In a reality of global competition, companies have to minimize production costs and increase productivity in order to boost com-petitiveness. Facility layout design is one of the most important and frequently used efficiency improvement methods for reducing operational costs in a significant manner. Facility layout design deals with optimum location of facilities (workstation, machine, etc.) on the shop floor and optimum material flow between these objects. In this article, the objectives and procedure of layout design along with the calculation method for layout optimization are all introduced. The study is practice-oriented because the described case study shows how the layout of an assembly plant can be modified to form an ideal re-layout. The research is novel and innovative because the facility layout design and 4 lean methods (takt-time design, line balance, cellular design and one-piece flow) are all combined in order to improve efficiency more significantly, reduce costs and improve more key performance indicators. From the case study it can be concluded that the layout redesign and lean methods resulted in significant reduction of the following seven indicators: amount of total workflow, material handling cost, total travel distance of goods, space used for assembly, number of workers, labor cost of workers and the number of Kanban stops.

Opis:
In a competitive market the manufacturing companies have to produce cost effective products which can be realized by minimized production cost and higher effectiveness. The effective facility planning can significantly reduce the operational costs of companies. An adequate facility layout can result in the improvement of the performance of the production line. The Facility Layout Problem (FLP) is relating to location of objects (departments, workstations, machines, etc.) on a given site and the material flow between these objects. The goal of this study is to show the reasons, objectives and steps of a layout redesign process. The minimization of the workflow realized on the shop floor is an often applied an objective function during the layout redesign. Material flow efficiency is a commonly used term for the determination of the amount of workflow, which is the multiplication of material flow data and distance data. In this study, this mathematical method for workflow calculation is introduced. The described case study shows how the efficiency and reduced manufacturing cost of a real manufacturing system can be improved by re-layout design, while smaller floor space is needed for the production.

Opis:
The article presents the results of measurements of selected thermal, moisture and mechanical properties of thermal insulating plaster, which is one of the alternatives to traditional methods of retrofitting the walls of buildings under conservation protection. An insulating plaster based on perlite was tested. Its thermal conductivity, vapor permeability and compression strength were determined. Images of the tested plaster under the microscope, at a magnification of 10-45x, were also taken. Through computer simulations, the possibility of improving the energy efficiency of an educational building by applying a layer of such plaster on external walls was determined. Changes in the heat loss structure were analyzed, and the obtained results were compared with the effectiveness of reducing heat loss through the walls using a traditional thermal insulation material. It turned out that the thermal conductivity coefficient of the tested plaster obtained by measurement was 0.0877 W/(m∙K), which confirmed the value declared by the manufacturer. Application of thermal insulating plaster with a thickness of 5 cm on the walls of the analyzed building, with other partitions of good thermal quality, reduced its energy demand by over 20%.

Opis:
After a short introduction characterizing the general outline of the issue, this paper describes the test results of oil leakage measurements through CVT actuator seals. The research was done using Jatco company's CVT 7model, the popular gearbox for small passenger cars. Several curves of leakage values are given for both actuators, concerning different conditions such as rotational speed, oil temperature or pressure. In the summary several conclusions are formulated, based on presented test results. The determined maximal value of leakage is about 1 l/min. It emerged that the influence of centrifugal force is negligible. What is more, the observed phenomena are shortly described and projected for more detailed investigation.

Opis:
During designing the ship its designer tends to obtain as high as possible efficiency of ship propulsion system. To this end on certain ships additional elements such as: nozzles, half-nozzles or suitably profiled fins attached to underwater part of ship’s hull before screw propeller, are applied (sometimes they are intended for the mitigating of vibration resulting from operation of screw propeller). Another device which affects operation of screw propeller is streamline rudder capable of improving its efficiency (most of the transport ships is fitted with single screw propeller and streamline rudder placed behind it). In this paper the influence of streamline rudder on screw propeller efficiency has been examined with the use of numerical methods of fluid dynamics (CFD).The obtained results indicate a very favourable influence of the rudder on screw propeller efficiency. Research in this area is continued and its results concerning impact of particular geometrical parameters of rudder on screw propeller efficiency, will be presented in the future.

Opis:
Evaluation of efficiency of the DMUs (Decision Making Units) in a company is a very important problem. Thus, the studies of evaluation of efficiency are being actively carried out on the basis of the production functions, for example Cobb-Douglas production function and fuzzy loglinear production function (fuzzy Cobb-Douglas model). Recently, DEA (Data Envelopment Analysis) was applied to evaluation of efficiency, in the sense of benchmarking evaluation. After having evaluated DMUs by DEA, we obtain the improvement plan for every input in the inefficient DMUs. Though we many not be able to decrease inputs at one time according to the DEA plan, it is natural to construct some phased improvement plans for decreasing the inputs. First, we propose to support the construction of some phased improvement plans by the sensitivity analysis for the evaluated efficiency by applicatiion of definite limits to the decrease of inputs. Second, we evaluate this method by applying it to the case of bank data.

Opis:
Lean has established itself as the primordial approach to obtain operational excellence. Its simple and intuitive techniques focus on reducing lead time through continuous improvement, involving all levels of employees in the organization. However, the rate of successful implementations has remained low. This paper contributes to the understanding of continuous improvement in a Lean context, by analyzing a database of almost 10.000 improvement actions, from 85 companies, covering the time frame 2010–2018. It discusses categories of actions, their impact and cost, as well as key characteristics of the companies. It proposes an objective criterion to identify “success” and “failure” in Lean implementation and tries to link these to operational results. It is probably the first time an analysis of this magnitude on the subject has been performed.

Opis:
Due to the pressure of competition, high process efficiency has become a corporate ob¬jective for companies to maintain their global competitiveness. To ensure high process efficiency, it is important to constantly reduce process losses within various business activities. Different concepts to evaluate the efficiency of a company's key processes have therefore been discussed in academia. These concepts largely concentrate on the production area of one single company. Currently, howev¬er, not only individual companies but also entire supply chains are competing with each other. For this reason, it is necessary to thoroughly evaluate and increase the efficiency of production, transport, handling, and warehousing processes along the entire Supply Chain. We addressed this challenge with the conceptual design of a supply chain improvement system (SCIS). The results of empirical research focussing on the managerial purpose of the SCIS indicate that intercompany efficiency evaluation and improvement are prevalent issues in entrepreneurial practice.

W artykule podsumowano argumenty w dyskusji naukowej na temat zarządzania wydajnością procesów w Przemyśle 4.0 jako podstawowego warunku doskonalenia procesów, eliminacji marnotrawstwa, wprowadzania innowacji, zdobywania przewag konkurencyjnych. Głównym celem badań było zbadanie wpływu diagramów procesów na możliwości doskonalenia procesów w produkcji zamówień w celu podniesienia jakości zamówień. Metody badawcze koncentrowały się na wykorzystaniu schematów blokowych dla poszczególnych procesów dla pewnego zamówienia. W badaniach wykorzystano wskaźnik efektywności procesu, wartości graniczne wskaźnika, analizę porównawczą. Przedmiotem badań był proces realizacji zamówienia w obszarze budownictwa. Trafność rozstrzygnięcia tego problemu naukowego była związana z jakością zamówień. W pracy przedstawiono wyniki wskazujące na znaczące usprawnienia w wybranym przedsiębiorstwie w poszczególnych procesach oraz podniesienie poziomu jakości świadczonych usług po zastosowaniu schematów blokowych dla procesów. W obszarze zasobów ludzkich i budżetowania zamówień obniżył się współczynnik efektywności, a pozostałe procesy wzrosły. Schematy blokowe w zarządzaniu procesami są bardzo skutecznymi instrumentami doskonalenia procesów. Wyniki mogą być przydatne do oceny wydajności procesów w produkcji zleconej w różnych dziedzinach przemysłu.

Opis:
Purpose: The aim of this article is to present the results of research on needs and possibilities of implementing Lean Management concept at the university. Using the literature review and the results of empirical research, author proposes specific solutions (tools). Design/methodology/approach: The aim of the research was carried out on the basis of latest world literature review and empirical research conducted at a Polish university, the domain of which is practical education. The article is a case study with a proposal for the implementation of LM in a selected university. The research covered selected organizational units of universities. Findings: Recommendations for the use of selected Lean tools is the need to rationalize the activities undertaken in universities, including continuous improvement and flexibility of processes. There are economically justifiable actions to reduce waste and losses occurring in universities, as well as the integration of diversified and often non-cooperating organizational (functional) units. The proposals presented in this article may become an inspiration for universities that are thinking about implementing previously unused improvement tools. Research limitations/implications: Empirical research has been limited to one university, and the proposed methods and tools relate to selected functional areas. LM implementation requires prior analysis of the needs and capabilities of each organization. Practical implications: Due to the functioning of universities in an increasingly difficult to predict environment, they are forced to look for ways not only to survive, but above all to continuously improve the entire organization. The implemented rationalization and development measures should contribute to the improvement of the effectiveness and efficiency of management. Unpredictable changes concern the legal, socio-cultural, economic and economic environment, as well as the COVID-19 epidemic situation. These challenges are met by the concept of LM - as an inspiration and an opportunity to accelerate remedial and pro-development actions. Originality/value: The article is dedicated to people interested in the theory and practice of the LM concept. The use of the methods and tools proposed by the author in various functional areas of the university may bring about beneficial changes in the form of improvements in activities, time savings, as well as rationalization and greater efficiency of the implemented processes.
