This study demonstrates application of Lean techniques to improve working process in a sewing machine factory, focusing on the raw material picking process. The value stream mapping and flow process chart techniques were utilized to identify the value added activities, non-value activities and necessary but non-value added activities in the current process. The ECRS (Eliminate, Combine, Rearrange and Simplify) in waste reduction was subsequently applied to improve the working process by (i) adjusting the raw material picking procedures and pre-packing raw material as per demand, (ii) adding symbols onto the containers to reduce time spent in picking material based on visual control principle, and (iii) developing and zoning storage area, identifying level location for each row and also applying algorithms generated from a solver program and linear programming to appropriately define the location of raw material storage. Improvement in the raw material picking process was realized, cutting down six out of 11 procedures in material picking or by 55%, reducing material picking time from 24 to 4 min or by 83%. The distance to handle material in the warehouse can be shortened by 120 m per time or 2,400 m per day, equal to 86% reduction. Lean techniques proved to provide significant improvement in sewing machine company operations.

The implementation of milk-run in Indonesia has been started since 2005. As a developing country, there is a challenge to operate milk-run smoothly especially in urban area due to severe traffic congestion and unfavourable road condition in some areas. This research aimed to analyze the practice of milk-run operation in one of the biggest Japanese automotive companies in Indonesia. Transportation Value Stream Mapping (TVSM) is applied in order to perform just-in-time delivery in the supply chain before operating milk-run. It is discussed that this company still need to continue in improving milk-run operation. The operation system needs control and integration from manufacturer, supplier and logistics partner. The advantage of milk-run operation is cost reduction and also support green logistics in decreasing emission of carbondioxide (CO2) by reducing the number of trucks used.

The main aim of this paper was to analyze the actual state of buying and selling cut-flowers in a chosen company. New controlling system was suggested for this company on the basis of collected and consequently separated, compiled and organized data. This system should provide the information on the anticipated development of purchase in the future. The motivation for creating the new system was given by the actual problems appearing due to not very clear and transparent way of flowers buying decision making. Especially considering the decisions about the amount and sorts of cut-flowers booked in advance. The new controlling system was designed in order to improve the current state of warehouse supply chain management. We believe that it would be useful in the process of planning, deciding, controlling and evaluation of orders exactness.

Współczesne trendy w logistyce skupiają się na efektywniejszym wykorzystaniu zasobów, eliminacji marnotrawstw oraz zachowaniu wysokiej elastyczności dla zwinnej odpowiedzi na zapotrzebowania klientów. Równolegle rozwijane są narzędzia komputerowego wspierania procesów logistycznych. Wydaje się zatem, że logistyka jest gotowa na przyjęcie założeń czwartej rewolucji przemysłowej definiowanej od 2011 roku jako Industry 4.0 za sprawą rządu Niemiec. Przedsiębiorstwa produkcyjne, dostosowując swoje procesy do zmiennych warunków rynkowych, często wdrażają wybrane koncepcje lean lub agile czy też realizują transformację zgodnie z wymaganiami zyskującej na popularności koncepcji Industry 4.0. Celem artykułu jest odpowiedź na pytanie problemowe: czy współczesne trendy w logistyce pokrywają się z założeniami Industry 4.0? W drugiej kolejności autorzy pytają czy zmiany zachodzące w środowiskach produkcyjnych znajdą odzwierciedlenie w procesach logistycznych? W ramach pracy autorzy dokonują subiektywnej oceny trendów realizowanych przez współczesne przedsiębiorstwa i określają na podstawie analizy literaturowej wyzwania, z którymi będą się one musiały zmierzyć w najbliższych latach.

Current trends in logistics focus on increase in efficient usage of resources, eliminating losses within process and maintaining high flexibility to nimbly answer clients’ needs. Simultaneously other tools are being developed like computer aided software for supporitng logistics processes. It seems that modern logistics is ready to answer needs which come out of fourth industrial revolution which is defined since 2011 as Industry 4.0 according to German government. Production companies, while adjusting to changing market conditions, very often implement different conecpts like lean or agile. Sometimes they try to transform according to Industry 4.0 concept’s requirements. The main target of the paper is to answer the question: are current trends in logistics are concurring Industry 4.0 assumptions? What is more authors ask about following changes in production environment and their reflection in logistcs’ processes. Within the paper authors prepared subjective evaluation of current trends in modern companies and described, on the basis of literature review, challenges which will have to be faced by these companies in following years.

Obecnie w wielu przedsiębiorstwach postrzega się Lean Logistics jako nową dziedzinę logistyki, wdrażaną w celu bardziej skutecznej redukcji kosztów. W rzeczywistości etiologia Lean Management, jak i nowoczesnej logistyki jest tożsama. Wywodzą się one z opracowanych w latach 50. przez K. Toyodę i T. Ohno założeń TPS (Toyota Production System), który ewoluował następnie do postaci Kaizen. Zarówno TPS, jak i Kaizen dotyczą organizacji zarządzania przepływem materiałów oraz logistyki i stanowią nie tylko spójną filozofię, lecz również zespół technik optymalizujących ten przepływ.

Both modern logistics and philosophy of Kaizen and Lean Management have common roots - Toyota Production System. Despite the common roots of their evolution during the last 60th year ran slightly different ways. Logistics has focused primarily on the business environment, Lean Management and Kazien on optimizing flows within company. Research, presented in this article, are the tools used to diagnose Kazien and Lean Management in Polish enterprises and the answer to the question whether the use of these tools would improve the functioning of logistics in the company.
