Obecnie przedsiębiorstwa produkcyjne funkcjonują w turbulentnym otoczeniu, co jest następstwem m.in. kryzysu światowego wywołanego przez pandemię i wojnę. Z tego względu są zmuszone do ciągłego poszukiwania rozwiązań umożliwiających obniżanie kosztów produkcyjnych, skracania czasu reakcji na potrzeby rynkowe czy wprowadzanie innowacyjnych rozwiązań z zakresu doskonalenia procesów produkcyjnych. Nowe spojrzenie na realizowane procesy produkcyjne zostało wymuszone przez zmieniające się i stale rosnące wymagania rynku oraz możliwość implementacji innowacyjnych rozwiązań techniczno-organizacyjnych. Zadaniem usprawnienia procesu produkcyjnego jest eliminacja strat i poszukiwanie źródeł marnotrawstwa, a także standaryzacja zaimplementowanych rozwiązań. Jednym ze sposobów poprawy efektywności i elastyczności procesów produkcyjnych jest koncepcja Lean, nastawiona na eliminację marnotrawstwa oraz skracanie cykli realizacji zamówienia w procesie. Do najważniejszych narzędzi stosowanych w koncepcji Lean Management należą: 5S, Kaizen, Just in Time, Just in Sequence, Kanban (system pull), Single Minute Exchange of Die (SMED), Total Productive Maintenance (TPM), Value Stream Mapping (VSM), standaryzacja, muda, Total Quality Management (TQM), takt time, heijunka, andon (Visual Management), poka yoke. Celem opracowania jest redukcja czasu przezbrojenia maszyny wykrawającej w procesie produkcji maty bitumicznej z zastosowaniem metody SMED.

Currently, production companies operate in a turbulent environment as a result, among others, of the global crisis caused by the pandemic and war. For this reason, they are forced to constantly search for solutions in the field, e.g., lowering production costs, shortening reaction time in response to market needs, or introducing innovative solutions to improve production processes. A new look at the production processes implemented was forced by the changing and constantly growing market requirements and the possibility of implementing innovative technical and organizational solutions. The task of streamlining the production process is the elimination of losses and the search for waste sources and standardizing the implemented solutions. One of the ways to improve the efficiency and flexibility of production processes is the Lean concept, which is focused on eliminating waste and shortening order fulfilment cycles in the process. The essential tools used in the Lean Management concept include: 5S, Kaizen, Just in Time, Just in Sequence, Kanban (pull system), Single Minute Exchange of Die (SMED), Total Productive Maintenance (TPM), Value Stream Mapping (VSM), standardization, muda, Total Quality Management (TQM), tact time, heijunka, andon (Visual Management), poka yoke. The paper aims to reduce the changeover time of the punching machine in the bitumen mat production process based on the use of the SMED method.

Originated as a production management philosophy, Lean Manufacturing has successfully transferred and implemented globally. Lean genealogy studies have been conducted, indicating the essential concept now evolves to Lean Management (LM), which is applicable to many branches of production and services management, viz quality and productivity, human resources, knowledge and technology, etc. Innovation has been made to ensure a smooth customization of knowledge and principles, tailored to each organization who is eager to implement this state-of-the-art management system. However, failures are becoming commonplace due to the lack of understanding the core values, and insufficient intensification of compensation for cultural differences. In this paper, cases of implementing LM across the Visegrád group (V4) and the ASEAN Free Trade Area (AFTA) from previous literature are taken into consideration. Factors that differentiate the characteristic of LM are brought to discussion. Therefore, the discovered gap between the two trade blocs urges the in-depth amendment and modification of employed concepts, tools, etc. A model is consequently elaborated, which aims at facilitate the managerial decision-making process regarding knowledge transfer of LM between V4 and AFTA, based on critical factors related to human, technology and culture, i.e. Labor cost, Manual requirement, Awareness, Continuous Improvement culture. This model can be used to predict the change should be made, or the criterion should be fulfilled to transfer the implementation and knowledge of LM effectively.

The article presents definitions of Lean Management. One of the methods of Lean idea, SMED, or Single-Minute Exchange of Die, is described in detail. The aim of this article is to present the implementation of the SMED method on the example of a PET bottle blowing machine and to show the benefits of using the SMED method in production. The influence of changeover times on the production process was analysed and evaluated according to selected measures of effectiveness of implemented measures. The work consists of six parts. The first part is an introduction, the second and third part is a description of the definitions of lean management and SMED. The fourth part of the article is the implementation of the SMED method, the fifth part is the analysis of rearmament of a PET bottle blow moulding machine. The last part of the paper are conclusions.

An effective and efficient New Product Development (NPD) and implementation process is crucial for creation of competitive advantage for each company. Due to this fact, companies are more and more often looking for methods and tools for improvement of NPD processes. The paper deals with an integrated Model Based Systems Engineering (MBSE) and lean approach to NPD. The individual stages of the NPD process are predisposed to different degrees to the use of MBSE and Lean. The research conducted shows that the use of advanced MBSE and lean tools and techniques in the development of new products is not widespread. There is a room for future research.
